8.3 FLIGHT PROCEDURES Flashcards
When given clearance in Metres, is it ok so set MCP with reference to metre read out?
8.3.9.1.1
Yes, can set initially based on metre read out, but level change cannot be executed until correct level referenced to FEET is verified.
What to set in MCP if METRE to FEET conversion is 3940’?
Ops 8.3.9.1
Round up or down to nearest 100’.
So this example, set 3900’.
Max wind speed at airport in including gusts, except emergency (take off and landing)
55kt
8.3.12
Thunderstorms
(Take off and landing)
8.3.12.1
Take off approach and landing SHALL not be attempted with moderate or heavy TS over or near the airport.
(UNLESS, app and landing can be made to runway clear of TS and associated front)
Flight crew should allow how much clearance from a THUNDERSTORM?
20nm
FO limits (8.3.4.4.1)
-TO and Landing crosswind 15Kts
(BTC’s max x/w, TC and STC max 25kt)
- landing following major mech failure or shutdown
- field length limited
- landing with weather less than 300’ and 1500m vis
- Alternate airport not familiar to both
- night visual at cat B
Lightning strike ops?
Subject to work load, check compass on various headings, and note in AML
(8.3.12.2)
Also inform ENG (inspection on arrival, perhaps 2 hours)
ASR? And AML?
HKIA ATLAS (Airport Thunderstorm and lightning alerting system)
Amber
Red
Amber:
lightning forecast to strike within 5km of airport.
Or intense radar echoes and lightning in range of 5-15 km
Red:
Cloud to ground lightning detected or forecast within 1Km
Min length of time for red or Amber lightning warning?
8.3.12.2
4 min (cannot be cancelled by ATC)
Amber lightning warning operations
Ramp activities as per normal.
Headset comm with engineer by wireless headset only
Red lightning warning considerations
8.3.12.4
Parking bay: siren and red light
Ramp activities:
-No walk around
-HAS bus can drop you at S21 passenger terminal
- all Maintenance ramp activities cease
(Fuelling, etc)
- policy to NOT use hand signals as comma with ground Eng
- occur during pushback, Eng will
Complete pushback, but cannot remove pin, and will seek shelter until over.
PASSENGER APRON
- allowed to taxi into frontal bays
- bridge connected when:
Park brake set
Engines off
Beacon off
- one crew member SHALL remain on FD to watch brakes, until ground comm established with ENG and chocks in.
I
Red lightning warning with inop APU? 8.3.12.4
Taxi in.
-Shut down Port engine, leave starboard engine running.
-Inform APRON CONTROL 121.775 that port engine shut down, brakes set, ready for disembarkation.
- this allows bridge to be connected
Red lightning warning on cargo bays or remote bays?
Marshalling at remote and cargo bays cease.
ATC will hold you.
What indicates sever Windshear?
8.3.12.5
below 1000’
-Airspeed changes greater than 15 knots
- VS changes greater than 500fpm
- 1 dot GS
- 5 degrees pitch
(CTWO BRIEF SHALL INCLUDE WINDSHEAR COUNTER MEADURES WHEN APPLICABLE)
JFK Windshear experience
Positive 15 knots at 1500’ and pitch went to -10 degrees.
Re-engaged autopilot and went around.
Then got -20 knots shear.
If this happened at 200’, scary.
Don’t be afraid to go around in positive shear environment, knowing negative shear coming.
If sever Windshear reported (not forecast), delay the takeoff until condition improve.
Microburst
Approach SHALL be discontinued, or
Departure delayed when microburst alerts or advisories in effect
Success of Windshear recovery depends on 3 things
Reaction time
Performance
Altitude
If aircrew encounter windershear, ensure you do a Pirep.
Include
Altitude
Loss or gain Of airspeed or altitude
Type of aircraft
Location.
Turbulence
8.3.12.7
Flight crew should avoid forecast or reported SEVERE turbulence.
ATC SHALL be advised as soon as practical of severe turb encounters and deviations from assigned ALT
BE SURE TO USE TURB PENETRATION SPEED (270 knot below F250…280 knot or M0.82 which ever lower at F250 or above)
Dealing with Passengers and ISM with turbulence.
Good communication key
SHALL BRIEF ISM prior, with expected level and duration.
Seatbelt signs SHALL be selected on
ISM safety PA
iSM shall inform captain that cabin checked and secure
(Of going to make a PA, use the handset, so not to wake up Over head crew rest)
Classification of turbulence
Description of severe:
Severe:
Large abrupt changes in altitude or attitude
Large airspeed changes
Momentarily out of control
Turbulence forecast for different phases:
Take off : Communication key
Inform cabin crew
Ensure seated until released.
Descent:
Turb penetration speed and maintain clean until reducing for approach
Diversion option if severe turb persists
Cont ignition on if an option
PA in case of Moderate or Severe turbulence when deemed necessary:
Hello everyone, observe the seatbelt signs are on, cabin crew, stop your service and take your seats.
When finished:
“Resume normal duties”
