Route and flight Planning
6.Fuel requirements – aeroplanes, helicopters
- Fly to the destination aerodrome;
- 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
7. Weather requirements – take-off, landing, alternate
- 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 clearance, Entry, Standard holding pattern, Non-standard holding pattern, Timing, Speed limitations, DME, Shuttle
- Holding Entries:Direct, Parallel,Teardrop
- Adjusting for Wind: Apply correction on outbound leg to maintain position.
- Always check NOTAMs and approach plates for any published holding pattern variations

230 | Holding 6,000 - 14,000 feet ASL | ||
250 | Below 10,000 feet ASL (general airspace speed limit | ||
265 | Holding > 14,000 feet ASL |
Approach Procedures
Approach Categories
- Approach categories are based on VREF (reference landing speed) or 1.3 × VS0 (stall speed in landing configuration), whichever is higher.
- Precision Approaches: ILS/PAR, provide both lateral and vertical guidance.
- Non-Precision Approaches: VOR/NDB/LOC/RNAV, provide lateral guidance only.
Approach Procedures
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
Approach Procedures
Missed Approach
- Initiate at DA (Decision Altitude) for precision or MDA + MAPt for non-precision.
- At DA/MDA, if you do NOT have the required visual reference, you MUST go missed.
- Never descend below DA/MDA unless Runway or runway markings, Runway Lights and approach lights sytem visible.
- RVR is reported and it's below the minimum required, do not pass FAF
Approach Procedures
Approach Ban
- ATC clearance does NOT override the approach ban.
- Approach categories are based on VREF (reference landing speed) or 1.3 × VS0 (stall speed in landing configuration), whichever is higher.
- Precision Approaches: ILS/PAR, provide both lateral and vertical guidance.
- Non-Precision Approaches: VOR/NDB/LOC/RNAV, provide lateral guidance only.
- Approach bans are based on visibility (RVR), NOT ceiling.
- You cannot continue an approach past the FAF if reported RVR is below minimums.
- Cannot continue below MDA/DH unless required visual references are in sight.
- You may continue if the RVR improves above minimums before reaching the FAF.
- Exceptions apply for certain aircraft with specific approach equipment (e.g., CAP GEN exemptions).
- Circling Approach: Requires maintaining visual reference with the airport.
- Approach Ban, a pilot must not continue an approach below the DA or MDA
- When:
RVR is less than 1,200 feet, or 1/4 SM visibility (unless specific exemptions apply) | Ground visibility is less than 1/2 statute mile,(depending,o,what's controlling and available) |

Meteorology
Low / High Pressure and Impact
- Definition
Low: A region of lower atmospheric pressure than surrounding air | High: A region of higher atmospheric pressure than surrounding air |
- Air Movement (Surface)
Low: Inward and counterclockwise (Northern Hemisphere) | High: Outward and clockwise (Northern Hemisphere) |
- Vertical Airflow
Low: Rising air (clouds, precip) | High: Sinking air (clears skies) |
- Flight Planning Alert
Low: Requires more planning for alternates, diversions, turbulence, icing | High: Easier VFR/IFR planning, stable conditions, fewer enroute concerns |
- Altimeter Setting Caution
Low: Rapid pressure drops possible → risk of altimeter under-reading | High: More stable pressure → altimeter readings more predictable |
- Altitude/Separation Risk
Low: From high to low, look out below! → risk of descending into terrain | High: Altimeter may over-read but with safer margin |
- Fuel Consumption
Low: Increased: headwinds, deviations, holds, more climb power needed | High: Decreased: tailwinds, smoother cruise |
- Aircraft Performance (Climb)
Low: Reduced climb performance in warmer, moist air; possible icing | High: Improved performance in cooler, dry air |
- Takeoff/Landing Conditions
Low: Poor braking action, crosswinds, gusts, low visibility | High: Calm winds, clear runway, better visibility |
- Ceilings & Visibility
Low: Often IFR/LIFR, below approach minima → possible approach ban | High: Typically VFR, high ceilings and good vis |
- Weather-Driven Delays
Low: Common: ATC flow restrictions, holding patterns, deicing delays | High: Rare: operations more predictable |
- Enroute Hazards
Low: CBs, turbulence, embedded TS, icing layers, sudden wind shifts | High: Smooth flight, low convective risk |
- Icing Conditions
Low: Common in stratiform or frontal cloud layers | High: Low risk, unless fog or frost on ground |
- Thunderstorm Potential
Low: High — especially near fronts or unstable airmass | High:Low — unless tropical or post-frontal instability |
- Turbulence Zones
Low: In/near fronts, CBs, LLWS (low-level wind shear) | 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 | High: Found behind cold fronts or large blocking high-pressure ridges |
- Pilot Decision-Making
Low: Requires flexibility, fuel margins, weather briefings, approach alternates | High: Lower workload and less contingency planning |
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.
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
Aviation Weather Reports
Aviation Forecasts
✪ 4. Aerodrome Forecasts (TAF)
- Provide forecasted/observed weather at airports.

✪ 6. Significant In-Flight Weather Warning Messages (SIGMET)
- Warn about severe weather like thunderstorms, icing, or turbulence.
Weather Maps and Prognostic Charts
Weather Interpretation
Instrumentation, Navigation and Radio Aids
Pitot Static System
- Blocked pitot tube → Airspeed increases in climb, decreases in descent.
- Blocked static port → Altimeter freezes, VSI shows no change.
- Blocked Pitot Tube (Drain Hole Open) → Airspeed reads zero
- Blocked Pitot Tube (Drain Hole Closed) → Airspeed acts like an altimeter
- Blocked Static Port → Airspeed, Altimeter, VSI all provide incorrect readings
Pitot Static Instruments
Gyroscopic Systems and Instruments
Magnetic Compass
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

- HSI (Horizontal Situation Indicator): Combines heading indicator and VOR/LOC course guidance.
Human Factors and Airmanship
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.
