What minimum separation with terrain should be maintained throughout the flight?
MOCA, in Magenta on the en route chart provides 1 500 ft / 2 000ft terrain separation.
MRA depiced on the OFP provide terrain and obstalce clearance 10NM either side of the route centerline inlucing a 10NM radius beyong the end points defining the route segment. Min MRA is 2000ft.
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 below the chart temperature limit:
Use managed FINAL APP mode to LNAV/VNAV DA not allowed.
If temperature is at or below 0 and above the chart temperature then temperature corrections are required to DA, IF and IAF, Missed Approach Altitude. Not required to FAF.
If the actual temperature is below the chart temperature limit:
- The approach may be flown only to the LNAV MDA.
- Temperature corrections are required DDA, IF, IAF, FAF, Vertical profile check heights, Missed Approach Alt
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
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.
PIC may operate to Category X airports on the basis of self-briefing from the appropriate charts, specifically noting the terrain hazards.
Example Subic Bay
Category A airport?
Airports satisfy the following requirements:
1. Approved instrument approach procedure
2. lease one runway supporting satisfactory take-off and/or landing performance
3. appropriate airport/runway lighting for night operations, where applicable.
PICs may operate unrestricted into Category A airports.
Category B airport?
Category B airports do not satisfy Category A requirements or are airports, which require additional evaluation due to non-standard approach aids and/or approach patterns, unusual local weather conditions, unusual characteristics or performance limitations, or any other relevant considerations (obstructions, physical layout, lighting, etc.).
PICs may operate after competency has been established by physical entry, or by one or more of the following:
* Simulator exercise (SIM)
* Audio-visual presentation (AV)
* Self-briefing (SB).
Category B Airport competency is valid for 12 months. Revalidation is by line operation (LINE OP), physical entry, audio-visual presentation, self-briefing or simulator exercise.
Note: Self-briefing (SB) alone is not considered sufficient to establish or maintain
competency at Category B airports marked with an asterisk (*).
Category C Airport?
Category C airports are Category B airports, which require additional evaluation. PICs may NOT operate until competency has been established by an Airport Briefing (AB) and either physical entry or a representative airport model simulator exercise approved for the purpose by the Regulatory Authority.
Category C Airport competency is valid for 12 months. Revalidation is by physical entry or an approved simulator exercise.
How should you correct altitudes in cold weather conditions?
Corrections to Enroute Altitudes: TEMPERATURE CORRECTION ISA-15 or above No correction ISA -15 to -24°C +10% ISA -25 to -34°C +15% ISA -35 to -45°C +20% > ISA -45°C +25%
The Cold Wx Altimetry calculator in the Aircrew Tools application or the Procedural Altitude Correction Table (Table B) shall be used to correct minima, procedural altitudes and 25NM MSAs and Terminal Arrival Altitudes (TAAs), where applicable.
What Cold WX Temp corrections are required to ILS and GLS approaches?
Apply the altitude correction to the following procedural altitudes:
1. DA,
2. IF and IAF altitudes,
3. FAF altitude,
4. Vertical profile check altitudes,
5. Missed Approach Altitude.
What are the colors of airport taxiway lights?
At the planning stage, what are the weather and fuel requirements when the destination airport is isolated (no alternate within 1 hour 30 minutes flight time of the destination)?
The requirement to nominate a destination alternate aerodrome can be waived subject to the
following requirements:
Note: Perth, Brisbane and Auckland are the only on-line destinations where Isolated
Aerodrome Reserve may be routinely applied. Use of this policy at other destination
aerodromes requires authorisation from the Line Operations or the Duty Operation
Manager.
Minimum RFF Category
At what maximum distance from landing threshold is the ILS beam protected (LOC/GS)?
Localiser:
Glidepath:
- 10NM within 8° of RWY centreline
What does the Alternate fuel account for?
Alternate Fuel is the fuel required to:
* Carry out a missed approach from the minima at destination
* Climb to cruising altitude
* Fly to an alternate airport via expected routing, plus 5% contingency fuel
* Descend and complete an approach to landing
Note: If the total distance along the expected routing is less than 90 NM, Alternate Fuel
planning will assume a minimum distance of 90 NM.
Alternate fuel is planned at CI – 0 (zero)
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?
En-route alternate airports supporting non-EDTO routes or route segments shall meet the requirements for an adequate airport. Refer to FOP OM-Part A 8.1.2.3–Adequate Airport. If more than one solution then no need to account for weather (D-EDG).
Unless engaged in EDTO operations, all flights shall be planned with the following restrictions:
1. Twin-engine aircraft are to remain within 60 minutes flight time at the one-engine inoperative cruising speed (calculated in ISA and still air conditions) of an adequate
