Part A Chapter 8 Flashcards
Minimum altitude requirements
• Vertical Separation:
- 1,000 ft for terrain/obstacle up to 5,000 ft AMSL
- 2,000 ft if terrain/obstacle is higher than 5,000 ft AMSL
• Lateral Separation:
- Track defined by 2 separate navaids, separation within
. 10nm either side of track
. 10nm beyond checkpoints
- Tracks not meeting previous criteria, separation within:
. 20nm either side of track
. 20nm beyond checkpoints
• En Route chart MOCA (Magenta color) provides:
- 1,500 ft separation for terrain up to 5,000 ft AMSL
- 2,000 ft separation if terrain higher than 5,000 ft AMSL
Cold weather altitude corrections
• Corrections to MSA, aerodrome temperature :
- ISA-15 or above, No correction
- Less than ISA -15°C add 10% to MSA
- Less than ISA -30°C add 20% to MSA
- Less than ISA -50°C add 25% to MSA
• Corrections for altitudes at or below MSA:
- Aerodrome temperature above 0°C, no corrrection
- Aerodrome at or below 0°C, use table in Part A or QRH
RNAV (GNSS) / GPS approaches, meaning of temperature limitation
• Actual temperature above chart temperature limit:
- Fly either
. FINAL APP mode to LNAV/VNAV DA
. NAV-FPA to LNAV MDA
- Temperature corrections are not required
• Actual temperature below chart temperature limit:
- Fly vertically selected NAV-FPA to LNAV MDA
- Cold weather corrections required, table in Part A/QRH
Precautions to avoid mountain waves and associated turbulence
- Do not fly through or close to rotor clouds adjacent to mountain ranges
- Overfly mountains by at least
- 5,000 ft for mountains up to 5,000 ft
- The height of the mountain if higher than 5,000 ft
• If mountain wave conditions are suspected, be prepared for turbulence even in clear air
• On routes within 20nm of terrain having a maximum elevation exceeding 2,000ft, increase safe altitude by: Elevation of Terrain Windspeed in knots
0-30 31-50 51-70 over 70
2,000-8000 ft 500ft 1,000ft 1,500ft 2,000ft Above 8000 ft 1,000ft 1,500ft 2,000ft 2,500ft
Lowest circling minima for Dragonair aircraft
Highest of:
- MDA 1,000 ft AAL / Visibility 4,600m
- Chart published minima
Precision Approach Light system guidance principle
Precision Approach Light System provides guidance from 300m before the runway threshold to 900m into the runway
Category X airport
• Airports that may not be nominated as a destination or alternate on the ATS Flight Plan but considered suitable for a non-scheduled landing
• Crew members may operate to Category X airports on the basis of self-briefing from appropriate charts
Example Subic Bay
Colors of airport taxiway lights
- Runway exits lights, alternate green and yellow until clear of ILS sensitive area
- Centerline lights, Green
- Edge lights, Blue
Planning stage, weather and fuel requirements for an isolated destination airport (no alternate within 1 hour 45 minutes flight time of the destination)
• Weather forecast from 30’ before to 2 hours after ETA:
- Visibility and ceiling above Company Minima for Filing as an Alternate
- Crosswind at or below aircraft and crew operating limit
• Fuel,
Alternate and Reserve Fuel is substituted by 2h holding fuel overhead destination at cruise consumption
• CFP, additional information provided:
- Critical Point (both 1 engine inop and depressurised)
- Point of No Return (1 engine inop)
NOTE: Use of this policy requires authorisation from Duty Operations Manager or Line Operations
Maximum distance from landing threshold where the ILS beam is protected (LOC/GS)
• Localiser:
- 25NM within 10° of LLZ course
- 17NM within 35° of LLZ course
• Glidepath:
- 10NM within 8° of RWY centreline
Alternate fuel
• Alternate fuel accounts for:
- 1 missed approach from minima at destination
- Fly to an alternate airport plus 5% contingency at CI 0
- 1 approach and landing at alternate airport
Minimum acceptable Rescue and Fire Fighting (RFF) level for the A320/321
• Minimum RFF category for A320 / 321
- Departure and destination 6(4) / 7(5)
- Alternate except ETOPS 4/5
(Takeoff, Destination, Critical Point Alternate)
- ETOPS Alternate 4
• Figures in brackets may be used for temporary downgrades not exceeding 72 hours
Planning stage, weather minima for En route alternates others than the ones nominated on the CFP for depressurization, Engine Out and ETOPS
1h before to 1h after Alternate ETA:
- Weather forecast at or above published landing minima
- Crosswind forecast at or below aircraft and crew limits
Planning stage, destination weather forecast indicates Low Visibility Operations in use
• Destination alternate must permit Cat 1 operations to protect against aircraft or airport systems downgrades
It means, airport with Non Precision Approach only is not acceptable!
Effect on operations of lightning warnings
• AMBER warning: Ramp activities continue as normal
• RED warning:
- Passenger Terminal Building:
. Passenger boarding/disembarkation is normal
. Cargo and baggage, loading/unloading is suspended
. Refueling operations are suspended
. Security staff operations are suspended
- Remote stands
. Crew transportation is suspended, if already at the stand crew stay in the bus until red warning is cancelled
. Passenger boarding/disembarkation is stopped
. Cargo and baggage loading/unloading is suspended
. Refueling operations are suspended
. Security staff operations are suspended - Pushback:
. Groundcrew disconnect their headsets and the ensuing engine start will be without ground support
. Pushback is suspended, however if the pushback has already commenced it continues until completed - Parking:
. Preferential Stand Allocation System suspended, aircraft are assigned in order of priority frontal then remote stands
. When all stands are occupied, aircraft hold on taxiway
. Marshalling:
Continues at the PTB
Suspended at remote stands
. Chocks not inserted, a crew member must remain on board to monitor brake pressure until ground crew contact is established
. If APU is inoperative:
Leave right-hand engine running
At a frontal stand contact Apron Control on 121.775 to advise park brake set, left engine shutdown and aircraft ready for passenger disembarkation
Planning stage, weather minima for destination alternate airport
• 1h before to 1h after Alternate ETA:
- Forecast visibility and cloud ceiling at or above Company specified Minima for Filing as an Alternate
- Crosswind forecast at or below aircraft and crew limits
• Provided they are at or above the applicable landing minima, the following forecast weather conditions may be ignored:
- PROB of any value
- TEMPO (changes for periods less than 60 minutes)
- INTER (changes for periods less than 30 minutes)
Planning stage, weather minima for a Take off alternate airport
At time of intended use:
- Weather conditions at take-off alternate must be at or above CAT 1 landing minima or the minima for the approach in use if no ILS available (visibility and ceiling required for a NPA)
- Crosswind forecast at or below aircraft and crew limits
Planning stage, weather requirements for En-Route Alternate airports nominated on the CFP for mandatory fuel and ETOPS Alternate airports
1h before to 1h after Alternate ETA:
- Forecast visibility and cloud ceiling at or above Company specified Minima for Filing as an Alternate
- Crosswind forecast at or below aircraft and crew limits
Planning stage, destination weather below landing minima or no forecast is available
• 2 destination alternate airports meeting the following requirements must be selected:
- Weather criteria for destination alternate
- Fuel planned to the most distant alternate
- Both destination alternates specified on ATS flight plan
Planning stage, weather minima for destination airport
• At time of intended use:
- Weather forecast at or above published landing minima
- Crosswind forecast at or below aircraft and crew limits
• Visibility:
- Forecast visibility can be converted to an equivalent RVR using Part A
- LVO minima may be used if the aircraft is appropriately equipped, crew qualified, and LVO approach available
- Following weather conditions may be ignored:
. PROB Visibility of any value
. TEMPO Visibility of any value
. INTER Visibility of any value
• Cloud ceiling:
- Evaluated for a precision approach
- Above appropriate MDH for a NPA
• Freezing Rain or Freezing Drizzle:
- Arrival can be planned during a forecast of Light Freezing Rain/Drizzle (-FZRA/-FZDZ)
- If destination forecast indicates Moderate or Heavy Freezing Rain/Drizzle nominated alternate shall not forecast any sort of Freezing Rain/Drizzle from 1 h before to 1 h after time of intended use
Reserve fuel
- Reserve Fuel is equal to 30 minutes holding at 1,500 ft based on aircraft planned landing weight at the alternate
- In the absence of available data the A320/321 will use 1,200/1,500kg
- Reserve Fuel is the company defined minimum fuel with which the aircraft must land
Depressurization fuel
• Sufficient fuel must be carried at any point on route to permit in case of loss of pressurization, failure of an engine or both:
- Continued flight to the nearest suitable ERA
- Hold at 1,500ft over that ERA for 30’
- Carry out 1 approach and landing
• If route analysis shows that above requirement is limiting a Route Brief will be published to indicate required minimum Diversion Fuel
Total Fuel
Total fuel is the sum of:
- Fuel Required
- Recommended Extra Fuel
Operational halt procedure
• IOC initiates the Operational Halt Procedure if:
- Flight is on the ground preparing for takeoff
- Loading variance exceeds Maximum ZFW, breaks a structural limitation or any other limit
• IOC shall immediately:
- Send ACARS message to the aircraft
“DO NOT TAKEOFF – LOADSHEET DATA ERROR”
- Call Station or ATC to stop the aircraft until data is verified and confirmed by a new Loadsheet
