PART A CHAPTER 8 Flashcards
How should you correct altitudes in cold weather conditions?
Corrections to MSA: TEMPERATURE CORRECTION ISA-15 or above No correction < ISA -15°C +10% < ISA -30°C +20% < ISA -50°C +25%
Corrections for altitudes at or below MSA:
Aerodrome at or below 0°C, use table in Part A or QRH.
What minimum separation with terrain should be maintained throughout the flight?
- 1 000 ft from obstacles or terrain up to 5,000 ft AMSL
- 2,000 ft from obstacles or terrain higher than 5,000 ft AMSL.
MOCA, in Magenta on the en route chart provides 1 500 ft / 2 000ft terrain separation.
In airspace where track is well defined by 2 separate navaids, separation must be maintained from obstacles and terrain within
10nm either side of track
10nm beyond checkpoints
Elsewhere separation must be maintained from obstacles and terrain within 20nm either side of track and 20nm beyond checkpoints.
For RNAV (GNSS) or GPS approaches, what is the meaning of the temperature limitation?
If the actual temperature is above the chart temperature limit:
o Use managed FINAL APP mode to LNAV/VNAV DA or selected NAV-FPA to LNAV MDA.
o Temperature corrections are not required.
If the actual temperature is below the chart temperature limit:
o The approach may be flown only to the LNAV MDA.
o Temperature corrections are required, table in Part A or QRH.
What are the precautions to avoid mountain waves and the associated turbulence ?
a. No flight through or close to rotor clouds adjacent to mountain ranges.
b. Overfly mountains by at least
- 5,000 ft for mountains up to 5,000 ft
- The height of the mountain for higher mountains
c. When flying in an area in which mountain wave conditions are suspected, always be prepared for turbulence, even in clear air.
d. Increase the safe altitude on routes within 20nm of terrain having a maximum elevation exceeding 2,000ft by at least the following increments to counteract wind effect:
Elevation of Terrain Windspeed in Knots
0-30 31-50 51-70 over 70 2,000-8,000ft 500ft 1,000ft 1,500ft 2,000ft Above 8,000ft 1,000ft 1,500ft 2,000ft 2,500ft
What are the lowest circling minima?
The minimum circle to land altitude and visibility for all Dragonair aircraft types is the highest of:
- 1,000ft AAL with a required visibility of 4,600m
- Chart published minima
How does the Precision Approach Light system helps the crew ?
Precision Approach Lighting Systems provide guidance
From 300m before the runway threshold to 900m into the runway.
What is a Category X airport?
Category X airports are airports which may not be nominated as a destination or alternate on the ATS Flight Plan but are considered suitable for use if a non-scheduled landing is required for operational necessity.
Crew members may operate to Category X airports on the basis of self-briefing from the appropriate charts, specifically noting the terrain hazards.
Example Subic Bay
What are the colors of airport taxiway lights?
- Taxiway Centerline lights:
Runway exits are marked with alternate green and yellow lights Taxiway centerline lights are green when clear of ILS sensitive area - Taxiway Edge lights:
Blue
At the planning stage, what are the weather and fuel requirements when the destination airport is isolated (no alternate within 1 hour 45 minutes flight time of the destination)?
a. Weather forecast from 30 minutes before to 2 hours after ETA:
- Visibility and ceiling shall above Company Minima for Filing as an Alternate
- Crosswind at or below the aircraft or crew operating limit.
b. Fuel, Alternate and Reserve Fuel must be substituted by 2 h holding fuel, at normal cruise consumption overhead destination.
c. CFP, a CP (both one engine inoperative and depressurised) and point of no return (one engine inoperative) will be provided.
NOTE: Use of this policy requires authorisation from the Duty Operations Manager or Line Operations department.
At what maximum distance from landing threshold is the ILS beam protected (LOC/GS)?
Localiser:
- 25NM within 10° of LLZ course
- 17NM within 35° of LLZ course
Glidepath:
- 10NM within 8° of RWY centreline
What does the Alternate fuel account for?
ALTERNATE FUEL accounts for:
i. 1 missed approach from minima at destination
ii. The flight to an alternate airport, plus 5% contingency
iii. 1 approach and landing at the alternate airport
Alternate Fuel is planned using Cost Index 0.
What is the minimum acceptable Rescue and Fire Fighting (RFF) level for the A330 ?
Minimum RFF category for A330
Departure and destination 9 (7)
Takeoff Alternate
Destination Alternate 7
Critical Point Alternate
ETOPS Alternate 4
Figures in brackets may be used in the event of a temporary downgrade not exceeding 72 hours.
At the planning stage, what weather minima applies to En route alternates others than the ones nominated on the CFP for depressurization, Engine Out and ETOPS?
1h before to 1h after the estimated time of arrival at the alternate,
- Weather forecast at or above the published landing minima
- Crosswind at or below the aircraft and crew limits
When the destination weather forecast indicates Low Visibility Operations in use, what additional precautions must be taken ?
A destination alternate which permits Cat 1 operations should be selected to protect against aircraft or airport systems downgrades.
It means NPA airport only not acceptable!
What is the effect on operations of lightning warnings?
AMBER warning: Ramp activities continue as normal
RED warning:
- Transport:
Passenger Terminal Building, transport continues normally
Remote stands, transport is suspended, If already at a remote stand crew remain on board the bus until red warning is cancelled.
- Ramp handling:
Cargo and baggage, loading/unloading is suspended.
Passenger boarding/disembarkation, continues normally at the PTB but is suspended at a remote stand.
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:
The Preferential Stand Allocation System is suspended and aircraft are assigned in order of priority frontal stand then remote stands. When all stands are full, aircraft will hold on the taxiway.
- Marshalling:
Continues at the PTB but is suspended at remote stands.
As chocks will not be inserted, a crew member must remain on board to monitor the brake pressure until ground crew contact is established.
If APU is inoperative, leave the right-hand engine running.
At a frontal stand, contact Apron Control on 121.775 to advise that the park brake is set, left engine is shutdown and the aircraft is ready for passenger disembarkation.
At the planning stage, what weather minima shall be used for the destination alternate airport?
1h before to 1h after the intended time of arrival at the alternate,
- Forecast visibility and cloud ceiling shall be at or above the Company specified “Minima for Filing as an Alternate”.
- Crosswind shall be forecast to be at or below the aircraft or crew operating limit.
Provided they are at or above the applicable landing minima, the following forecast weather conditions may be ignored:
i. PROB of any value
ii. TEMPO (changes expected to occur for periods less than 60 minutes)
iii. INTER(changes expected to occur for periods less than 30 minutes)
The “Minima for Filing as an Alternate” are calculated by Navigation Services Unit and shown on the CFP; they are the higher of Company calculated or, where published, State operating minima.
At the planning stage, what are the weather minima for a Take off alternate airport?
At the time of intended use,
- Weather conditions at the take-off alternate must be at or above the CAT 1 landing minima or the minima for the approach in use if no ILS available (visibility and ceiling required for a NPA)
- Crosswind at or below the aircraft and crew limits
At the planning stage, what are the weather requirements for CFP nominated En-route and ETOPS alternate airport?
En-Route Alternate airports nominated on the CFP in support of engine inoperative or depressurisation mandatory fuel and ETOPS Alternates, should have the following weather conditions:
From 1h before to 1h after the ETA at the alternate
- Weather conditions shall be at or above the Company specified Minima for Filing as an Alternate.
- Crosswind at or below the aircraft and crew limits
At the planning stage, what additional precautions must be taken if the destination airport weather is below landing minima, or no forecast is available?
2 destination alternate airports shall be selected
Both destination alternate airports shall have the following requirements:
a. The weather shall meet the criteria for filing as a destination alternate.
b. Fuel shall be planned to permit diversion to the most distant of the 2 selected alternates.
c. All destination alternates shall be specified on the ATS flight plan.
At the planning stage, what are the weather minima for the destination airport?
At the time of intended use,
- Weather conditions shall be at or above the published landing minima.
The following criteria apply assessing the weather
a. Following forecast visibilities (Ceiling must be above minima) may be ignored:
i. PROB of any value
ii. TEMPO (changes expected to occur for periods less than 60 minutes)
iii. INTER* (changes expected to occur for periods less than 30 minutes)
* Note: The term INTER is not used by all States.
b. Visibility, when converted to an equivalent RVR, is at or above the minima for landing.
LVO minima may be used if the aircraft is appropriately equipped, the crew qualified, and a LVO approach is available.
c. Cloud ceiling shall be evaluated but it’s not a limiting factor for a precision approach.
For a non precision approach, the cloud ceiling shall be at or above the appropriate MDH.
d. Crosswind shall be evaluated in relation to aircraft and crew limits.
e. Arrival may be planned during periods of forecast Light Freezing Rain (-FZRA) or Light Freezing Drizzle (-FZDZ).
However, if the destination forecast (including PROB, TEMPO or INTER) for the relevant period indicates the presence of Moderate or Heavy Freezing Rain, Drizzle, then the nominated alternate shall not have a forecast (including PROB, TEMPO or INTER) of -FZRA, FZRA, +FZRA, -FZDZ, FZDZ, +FZDZ for the period from one hour before until one hour after the time of intended use.
What is Reserve fuel?
Reserve Fuel is equal to 30 minutes holding at 1,500 ft based on aircraft’s planned landing weight at the alternate.
In the absence of available data the A330 will use 2,600kg.
Reserve Fuel is the company defined minimum fuel with which the aircraft must land.
What is the Depressurization fuel?
Sufficient fuel must be carried at any point on the planned route to permit in case of loss of pressurization, failure of an engine or both:
a. Continued flight to the nearest suitable ERA
b. Hold at 1,500ft over that ERA for 30’
c. Carry out 1 approach and landing.
On any Dragonair route for which the route analysis shows that the above requirement is limiting, a Route Brief will be published to indicate the minimum Diversion Fuel Required along the planned route.
What is Total Fuel?
Total fuel is the sum of:
a. Fuel Required
b. Recommended Extra Fuel
What is the Operational halt procedure?
IOC will initiate the Operational Halt Procedure if :
- The flight is on the ground preparing for takeoff
- The loading variance exceeds the Maximum ZFW, breaks a structural limitation, or any other limit
IOC shall immediately
- Send the following ACARS message to the aircraft:
“DO NOT TAKEOFF – LOADSHEET DATA ERROR”
- Telephone the Departure Station or ATC to stop the takeoff until the data is verified and confirmed by a new Loadsheet.
