• Execute an approach and a missed approach;
• Fly to and land at the alternate aerodrome;
• Then fly for an additional 45 minutes at normal cruising speed.

Route and flight Planning

• Ensure that the destination's forecasted weather from one hour before to one hour after your ETA meets the required minima: a ceiling of at least 1,000 feet above the FAF altitude and visibility of at least 3 statute miles

Departure Procedures

• Single-engine aircraft require 1 SM visibility for IFR takeoff (unless otherwise published).
• Multi-engine aircraft may take off with ½ SM visibility.
• Takeoff alternates are required when the departure airport is below landing minima, not just because visibility is low.
• Takeoff Minima: Based on aircraft category; RVR 1200 or greater required in most cases, and check the airport’s published IFR takeoff minima in the CAP GEN and departure charts.

En Route Procedures

Intercept

• Use a 30°-45° intercept angle when joining a VOR radial for efficient tracking.
• CDI full deflection means you are far off-course—use an intercept heading.
• Inbound radial means flying opposite to the radial’s bearing (270° radial = 090° inbound).
• Avoid excessive corrections—small adjustments help maintain course accuracy.

En Route Procedures

1. Position reports

• Position Reports: Required in non-radar environments and for altitude changes.

En Route Procedures

4. Altitude Limitations – MEA, MOCA, MRA, GASA

Holding Procedures

• Holding entries: Direct, Parallel, Teardrop.
• Standard hold = right turns.
• Non-standard hold = left turns.
• Fix is the centre of the holding picture.
• Radial = FROM the station; inbound course is normally the reciprocal.
• Direct entry = cross the fix and join the racetrack right away.
• First crossing = entering; after completing the entry and crossing the fix again = established.
• Report established after completing the entry and joining the normal racetrack, not simply at the first fix crossing.
• At or below 14,000 ft ASL → 1 minute outbound/inbound timing target.
• Above 14,000 ft ASL → 1.5 minutes outbound/inbound timing target.
• Start outbound timing abeam the fix or when established on the outbound heading, whichever occurs later.
• Abeam = the fix is beside you, about 90° off the wing.
• At or below 6,000 ft ASL → maximum holding speed 200 KIAS.
• 6,001 ft to 14,000 ft ASL → maximum holding speed 230 KIAS.
• Above 14,000 ft ASL → maximum holding speed 265 KIAS.
• If a chart publishes a lower holding speed, the published chart restriction wins.
• DME hold = use distances, not timing.
• Hold between 10 DME and 15 DME → leg length is 5 NM.
• In a 10–15 DME hold: turn outbound at 10 DME and turn inbound at 15 DME.
• Inbound too long → shorten the next outbound leg.
• Inbound too short → lengthen the next outbound leg.
• Outbound wind correction = about 3 × inbound correction, opposite direction.
• Inbound too long → outbound shorter; inbound too short → outbound longer.
• Inbound correction × 3, opposite side outbound.

• 🧠 Standard = right; non-standard = left.
• 🧠 6 / 14 / above = 200 / 230 / 265.
• 🧠 Chart beats the general holding-speed table.
• 🧠 Inbound too long → outbound shorter.
• 🧠 Inbound too short → outbound longer.
• 🧠 Inbound correction × 3, opposite side outbound.
• Example: Hold east on the 090 radial → holding area east of VOR, outbound 090°, inbound 270°.
• Example: Hold north on the 360 radial → holding area north of VOR, outbound 360°, inbound 180°.
• Wind direction aid: If you correct right, the wind is coming from your left.
• 🧠 Inbound too long → outbound shorter; inbound too short → outbound longer.

• Used for circling minimums.
• Used for protected airspace radii.
• Used for charted approach lines and different minima by category.

• 🧠 Category speed drives protected airspace and minima.

An LPV (Localizer Performance with Vertical guidance) approach:

• Is an RNAV (GNSS) approach
• Uses WAAS (Wide Area Augmentation System)
• Provides both lateral and vertical guidance
• Uses a DA (Decision Altitude), like an ILS
• But is not classified as a precision approach under ICAO

Missed Approach

• DA = Decision Altitude: decide immediately, land or missed.
• MDA = Minimum Descent Altitude: maintain MDA until the MAP unless visual reference is established.
• Non-precision approach uses MDA and MAP.
• Precision/APV approach uses DA.
• At MAP on a non-precision approach, if runway environment is not in sight → execute missed approach.
• At DA on ILS/LPV/LNAV/VNAV, if runway environment is not in sight → execute missed approach immediately.
• Do not descend below DA/MDA unless the required visual reference is established and the aircraft is in a normal position to land.
• Do not level off at DA; DA is a decision point, not a level-off altitude.

• 🧠 DA = Decide Now.
• 🧠 MDA = Maintain Until MAP.
• 🧠 No runway at MAP = go missed.
• 🧠 DA/MDA tells you if you may continue to land.
• 🧠 LP/LNAV use MDA; LNAV/VNAV/LPV use DA.

• Reference table included here: MDA vs DA comparison.

Approach Ban

• Approach ban = gate before final.
• Approach ban is checked before continuing past the FAF.
• Approach ban is based on reported visibility/RVR, not ceiling.
• ATC approach clearance does not cancel the approach ban.
• RVR = Runway Visual Range, the distance a pilot can see along the runway.
• RVR 2600 is commonly treated as about 1/2 SM.
• You may continue if RVR improves above minimums before reaching the FAF.
• If RVR drops after passing the FAF, continue only if legally allowed and required visual reference exists at DA/MDA.
• Circling approach requires maintaining required visual reference with the airport/runway environment.
• DA/MDA is the landing decision point after the approach-ban gate has been satisfied.

• 🧠 Approach ban = gate before final.
• 🧠 Approach ban tells you if you may continue inbound.
• 🧠 DA/MDA = landing decision.
• 🧠 DA/MDA tells you if you may continue to land.
• 🧠 RVR = runway seeing distance.
• 🧠 Approach ban = gate before final; DA/MDA = landing decision.

• Or radial + DME (e.g., 270° radial at 15 DME).
• Or radial + NDB bearing.

• VOR Bearings

• Radial = direction FROM the station.
• Bearing = direction TO the station.
• Example: If you are on the 090° radial, the station lies on a 270° bearing TO.

• Crosschecks

• Used to verify position along airways:
• ➤ VOR/VOR cross radials.
• ➤ VOR/DME (radial + distance).
• ➤ VOR/NDB (radial + relative bearing).
• Helps confirm you are at the correct fix for reporting or procedure turns.

• 🧠 Memory Tip

• “Fix = one line + one distance or two lines.”
• ➤ Two radials crossing, or
• ➤ One radial + DME, or
• ➤ One radial + ADF bearing.

2.7 STARs and RNAV Arrivals – Interpretation and Constraints

• STAR = published IFR arrival route from the enroute structure to a terminal fix/transition.
• Cleared via STAR = fly the STAR laterally as published.
• Descend VIA STAR = obey published altitude and speed restrictions.
• Descend to 5,000 = ATC altitude replaces/cancels published altitude restrictions, unless ATC says otherwise.
• Speed restrictions remain unless ATC cancels them.
• No STARs = expect vectors or other ATC instructions.
• Fly-by waypoint = turn anticipation allowed.
• Fly-over waypoint = cross the waypoint before turning.

• 🧠 STAR = arrival recipe.
• 🧠 Descend VIA = obey all restrictions.
• 🧠 Fly-over = over the point first.
• 🧠 RNAV STAR = ±1 NM accuracy required unless otherwise specified.

• STAR Chart Interpretation

• STARs are made of transitions from enroute fixes → common route → terminates at a fix or navaid for an approach.
• Clearance wording matters:
• ➤ Cleared via the OAKVL 1 STAR” = fly the STAR as published
• ➤ Cleared direct OAKVL, then OAKVL 1 STAR” = join STAR at OAKVL fix
• If “No STARs” in clearance, ATC will vector you instead.

• Altitude & Speed Constraints

• Depicted with lines/symbols:
• ➤ At (underline): 6,000 → must cross at exactly 6,000 ft.
• ➤ At or Above (line below): 6,000 → cross ≥6,000.
• ➤ At or Below (line above): 6,000 → cross ≤6,000.
• ➤ Window (box): 4,000–6,000 → cross within that range.
• Speed restrictions also published (e.g., “MAX 250 KIAS”).

• RNAV STARs

• Require RNAV 1 accuracy (±1 NM 95% of the time).
• Some may have RNP values specified.
• Lateral paths defined by waypoints (fly-by or fly-over).
• Vertical constraints ensure safe descent and spacing.

• ATC Interaction

• Clearance “descend via the STAR” means comply with all altitude & speed constraints as published.
• Clearance “descend 5,000” cancels published altitudes and replaces them with ATC instructions.

2.8 ILS, LOC, Back Course, GS Interception

• ILS = localizer plus glide slope; lateral and vertical guidance.
• LOC = localizer only; lateral guidance only; non-precision.
• Back Course = back lobe of localizer; no usable glide slope.
• For a back course, set the front course on the OBS/HSI to avoid reverse sensing.
• Intercept glide slope from below at the published altitude.
• If glide slope is intercepted from above, the approach may be unstable or misleading.

• 🧠 ILS = two needles.
• 🧠 LOC = lateral only.
• 🧠 BC = back course, no glide slope.
• 🧠 Always intercept GS from below.

• LOC (Localizer)

• Lateral guidance only, no GS.
• Can be flown as a stand-alone non-precision approach (LOC approach).
• Minima: MDA higher than ILS.

• Back Course (BC)

• Uses the back lobe of the localizer.
• Provides reverse sensing unless front course is set in OBS/HSI.
• GS is not used — only lateral guidance.
• Higher minima (often ~500–700 ft).

• Glide Slope Interception

• Usually intercepted from below (e.g., from the FAF or GS intercept altitude).
• If intercepted from above → unstable, may cause false capture.
• At intercept altitude, GS alive → descend to follow the slope.

2.9 Missed Approach Segments: Procedure and Obstacle Avoidance

• For precision/APV: missed approach begins at DA if required visual reference is not established.
• For non-precision: missed approach begins at MAP if required visual reference is not established.
• Climb gradient is normally 200 ft/NM unless a higher gradient is published.
• Pilot begins climb at DA/MAP, not later.
• Missed approach has initial, intermediate, and final segments.

• 🧠 DA/MAP = do not delay.
• 🧠 Missed = Initial climb, Intermediate track, Final to hold.
• 🧠 200 ft/NM unless higher published.

Segments of a Missed Approach

• Initial Segment

• Begins at the MAP/DA.
• Pilot executes immediate climb along published track.
• Starts obstacle clearance guarantee.

• Intermediate Segment

• From the end of the initial climb to where you’re established on the published missed approach track.
• Obstacle clearance gradually increases.

• Final Segment

• Extends from end of intermediate to the missed approach holding fix.
• Provides full obstacle clearance (at least 1000 ft).

Obstacle Avoidance Assumptions

• Climb gradient: 200 ft/NM (≈ 3.3%) unless higher published.
• Pilot begins climb at DA/MAP, not later.
• Straight ahead until reaching 400 ft AAE before any turns (unless procedure specifies otherwise).

2.3 DME Slant Range and Fix Identification

• DME measures slant range, not pure horizontal ground distance.
• At 6,000 ft directly overhead a DME, the DME may read about 1 NM.
• DME arc correction: if DME is greater than desired, turn toward the station; if DME is less than desired, turn away.
• For DME arc lead-in, start the turn before the desired radial to avoid overshooting.

• 🧠 DME is the hypotenuse.
• 🧠 Twist 10, turn 10 for DME arc tracking.

2.12 Approach Plate Symbols and Fixes

• Approach plate symbols identify where final approach begins, where missed approach begins, and where supporting fixes are located.
• FAF usually marks the start of final approach on non-precision approaches.
• FAP or glide path intercept point can mark the start of final descent on precision/APV approaches.
• IF is between the IAF and FAF and prepares the aircraft for the final approach segment.
• IAF is the starting point for the initial approach segment.
• MAP is the point to execute the missed approach if required visual references are not established.

• 🧠 IAF → IF → FAF/FAP → MAP/DA → missed or land.
• 🧠 FAF for non-precision; FAP/GP intercept for precision/APV.
• 🧠 MAP = missed approach point on non-precision approaches.
• 🧠 DA = decide now; MDA = maintain until MAP.
• Reference table included here: approach plate symbols.

• High: Minimal, often limited to terrain-induced or mechanical turbulence

• Radio/Nav Issues

• Low: Possible signal distortion near CBs or due to static discharge
• High: Better signal reliability

• Mountain Flying

• Low: Tricky: updrafts, downdrafts, turbulence, pressure differentials
• High: Safer: stable airmass, more predictable performance

• Runway Selection Impacts

• Low: Changing wind directions → may require opposite runway or last-minute change
• High: Stable wind direction, easier runway planning

• Common Synoptic Feature

• Low: Found with fronts, troughs, occluded systems, or tropical cyclones

Fundamentals of Weather

9. Air masses - Effects of a Cold Front on Flight Operations

• Cold fronts are dynamic and cause sudden weather changes.
• Expect strong turbulence, wind shear, and convective cloud development (CB).
• Significant temperature drops and pressure rises occur after frontal passage.
• Precipitation is often heavy, short-lived, and associated with thunderstorms.

Icing

3. Effects on aircraft performance

• Avoid icing conditions between -10°C and -20°C in visible moisture.
• Rime ice = rough, opaque, brittle; usually small droplets in stratiform cloud.
• Clear ice = smooth/glaze; usually large droplets and often the most dangerous.
• Mixed ice = combination of rime and clear ice.
• Freezing rain or large-droplet icing can create rapid clear ice and should be avoided.

• 🧠 Clear ice = clear danger.
• 🧠 Icing + visible moisture near freezing = plan an exit.

Turbulence

• Climbing to a higher altitude can help avoid icing layers and turbulence.
• Descending into a low-pressure system is often a bad idea, as icing and turbulence may worsen.
• ATC vectors are useful but may not always be available; altitude selection is the pilot’s responsibility.
• Check GFA (Graphical Area Forecast) and SIGMETs for freezing levels and turbulence advisories.

Turbulence

1. Mechanical

• Caused by terrain and buildings

Turbulence

2. Thermal

• Rising
• warm
• air

Turbulence

3. Frontal

• associated with cold fronts

Turbulence

4. Wind Shear

• Wind shear can cause sudden airspeed and altitude loss, making approaches extremely dangerous.
• If wind shear is encountered below 1,000 feet AGL, an immediate missed approach is the safest response.
• Do not attempt to 'power through' severe wind shear—escape the hazard by climbing out of it.
• Low-Level Wind Shear (LLWS) advisories should always be taken seriously, especially during approach.

Turbulence

4. Flight precautions

Thunderstorms

• Mature thunderstorm stage has the greatest combination of hazards.
• Avoid thunderstorms laterally; do not try to pick through embedded cells.
• Microburst sequence: headwind gain, downdraft, tailwind loss.
• Wind shear on approach = go-around/escape if unsafe.

• 🧠 Mature thunderstorm = maximum hazard.
• 🧠 Microburst = gain, sink, loss.
• 🧠 Wind shear warning close to the ground = escape/go around.

Aviation Weather Reports

• METAR = current observed aerodrome weather.
• SPECI = special observation issued when significant changes occur.
• SIGMET = severe/significant weather warning.
• AIRMET = moderate or widespread weather hazard.
• PIREP = actual pilot report, useful but local and time-sensitive.

• 🧠 SIGMET severe; AIRMET moderate.
• 🧠 PIREP = pilot saw it.

Aviation Forecasts

4. Aerodrome Forecasts (TAF)

• Provide forecasted/observed weather at airports.
• TAF TEMPO = temporary fluctuations.
• TAF BECMG = gradual change to new prevailing conditions.
• TAF PROB = probability group.
• GFA cloud bases/tops are normally ASL unless marked SFC.
• GFA ICG = icing; TURB = turbulence; FZLVL = freezing level.
• FD winds code gives wind direction, wind speed, and temperature.
• FD 9900 = light and variable wind.
• For FD winds of 100 kt or more, add 50 to direction and subtract 100 from speed.

• 🧠 TEMPO = temporary.
• 🧠 BECMG = becomes.
• 🧠 GFA = big picture weather map.
• 🧠 FD 9900 = calm/light variable.

Aviation Forecasts

6. Significant In-Flight Weather Warning Messages (SIGMET)

• Warn about severe weather like thunderstorms, icing, or turbulence.

Weather Maps and Prognostic Charts

Weather Interpretation

Pitot Static System

• Blocked pitot tube with drain hole open → ASI reads zero.
• Blocked pitot tube with drain hole closed and static clear → ASI acts like an altimeter.
• Blocked static port → altimeter freezes, VSI shows zero, and ASI reads low in climb / high in descent.

• 🧠 Pitot-only = airspeed.
• 🧠 Pitot-only problem = airspeed problem.
• 🧠 Static = altitude/VSI/airspeed.
• 🧠 Static problem = altitude, VSI, and airspeed affected.
• 🧠 Pitot-only = airspeed; static = altitude/VSI/airspeed.

Pitot Static Instruments

Gyroscopic Systems and Instruments

• Vacuum failure usually affects attitude indicator and heading indicator.
• Turn coordinator is commonly electric.
• If attitude indicator fails, cross-check turn coordinator, heading, altimeter, VSI, and standby instruments.

• 🧠 Vacuum often drives AI/HI; electric often drives TC.

Magnetic Compass

• Compass turning errors are strongest on north/south headings.
• Compass acceleration/deceleration errors are strongest on east/west headings.
• UNOS = undershoot north, overshoot south.
• ANDS = accelerate north, decelerate south.

• 🧠 UNOS and ANDS for compass errors.
• 🧠 UNOS = undershoot north, overshoot south.
• 🧠 ANDS = accelerate north, decelerate south.

VOR

• Provides radials; tracking inbound requires a TO indication, outbound requires FROM.

ADF NDB

• Aircraft heading affects needle but not station location.

ILS

GNSS

5. RAIM, Fault Detection & Exclusion

• GPS RAIM: Required for GNSS approaches to ensure signal integrity.
• RAIM (Receiver Autonomous Integrity Monitoring): Checks GPS signal integrity before using RNAV.

Transponder

Other Systems – Basic Principles and Use

1. DME

• Provides slant-range distance (not ground distance).

Other Systems – Basic Principles and Use

2. VORTAC

Other Systems – Basic Principles and Use

5. Horizontal Situation Indicator (HSI)

• HSI (Horizontal Situation Indicator): Combines heading indicator and VOR/LOC course guidance.

Glass Cockpit Displays and Failures

• PFD failure: use standby instruments and reversionary mode if available.
• AHRS failure affects attitude/heading.
• ADC failure affects airspeed, altitude, and VSI.
• MFD may still provide map/engine/weather/traffic information if the PFD fails, depending on installation.

• 🧠 AHRS = attitude/heading.
• 🧠 ADC = air data: airspeed, altitude, vertical speed.

IFR Fuel Requirements and Planning Memory Aids

• IFR fuel planning includes taxi, trip, alternate if required, holding/contingency, and reserve.
• Private IFR reserve planning commonly uses 45 minutes at normal cruising speed.
• Fuel totalizer can be useful for endurance, but required fuel planning must still be conservative and legal.

• 🧠 IFR fuel = Taxi, Trip, Alternate, Holding, Reserve.
• 🧠 IFR fuel = T-T-A-H-R: Taxi, Trip, Alternate, Holding, Reserve.

Takeoff, Alternate, and Landing Planning

• Takeoff alternate is needed when the departure aerodrome is below landing minima or unsuitable for return.
• Destination alternate depends on destination forecast conditions around ETA and applicable rules.
• ATC clearance does not remove pilot responsibility for weather minima and aircraft legality.

• 🧠 Takeoff legal does not always mean return landing is legal.
• 🧠 Weather minima are pilot responsibility.

De-Icing, MEL/CDL, Wake Turbulence

• Clean aircraft concept: no takeoff with frost, ice, or snow adhering to critical surfaces.
• MEL = relief for inoperative equipment with conditions.
• CDL = relief for missing external parts with restrictions.
• ATC cannot waive aircraft airworthiness/equipment requirements.
• Wake turbulence sinks and drifts with the wind.
• Intersection departure behind a heavy normally increases wake wait time.

• 🧠 Clean wing, clean tail, clean prop, clean sensors.
• 🧠 MEL says if you may go; ATC only clears traffic.
• 🧠 Wake sinks and drifts.
• 🧠 Intersection adds time.

Aviation Physiology

Aviation Psychology

Pilot - Equipment/Materials Relationship

Controlled Flight into Terrain (CFIT)

• Spatial Disorientation: Occurs when the body’s senses contradict instrument readings; rely on instruments.
• Hypoxia: Lack of oxygen at altitude, leading to impaired decision-making.
• Fatigue: Reduces reaction time and situational awareness.
• Controlled Flight into Terrain (CFIT): Happens when the aircraft is flown into the ground due to lack of situational awareness.

IFR Airmanship – Approach Stabilization and Decision Discipline

• Do not continue an unstable approach just because the runway is nearby.
• DA requires an immediate land/missed decision.
• MDA requires disciplined level flight until MAP unless visual reference is established.
• If unsure of position or terrain clearance, use the appropriate safe altitude and communicate with ATC.
• Workload management includes briefing the approach, setting avionics early, and knowing the missed approach before final.

• 🧠 Brief before busy.
• 🧠 No visual at DA/MAP = go missed.
• 🧠 Aviate, navigate, communicate.
• 🧠 DA = Decide Now; MDA = Maintain Until MAP.
