Atlantic Operations Flashcards
When do ACARS clearance requests need to be sent to ANSPs before entry.
Gander: 60-90 mins (Flights departing less than 45 mins from OEP need to send message 10 mins before start up.
Shanwick 30-90 mins
Reykjavik: No earlier than 20 mins
Santa Maria: At least 40 mins before.
RVSM altitude
Aircraft should be within +/- 200ft
Climb and descent should be limited to 2000ft per min or 1000 ft per min when within 5nm of other aircraft.
Any deviation of 300ft or greater needs to be reported to the competent authority within 72 hours.
RVSM requirements
Two primary altitude measuring systems
One automatic altitude control (holding) system
One altitude alerting device
Operating transponder.
60/60 Rule
After certain defects have been rectified aircraft must fly for 60 mins before entering ETOPS airspace
RFFS categories
330-300: 9
330-200: 8
A321N: 7
A320N/320: 6
A330 positioning operations for departure and destination and respective alternates. RFF -2
A330: For passenger ops RFF-1 (RFF -2 still applies to alternates)
With temp downgrade by NOTAM destination and departure allowed RFF-2, alternates RFF -3 both with max downgrade to RFF 4
ETOPS E route alternates allowed RFF 4 with 30 mins notice for all operations.
RVSM requirements
1 Altitude Alerting Systems
1 Alt hold system
2 Altimeters
1 SSR Transponder
NAT HLA Requirements
FL 285-FL 420
RNP 10 (2 LRNS)
2LRCS: HF and either satcom or CPDLC (FL290-410)
ADS-C (FL290-410)
PBCS requirements
(FL 350-390)
RCP 240
RSP 180
RNP4
The following may qualify for a diversion
Pilot incap
Engine failure
Rapid decompression
Crew or passenger sickness
Bomb/security threat
Smoke/fire
One hydraulic system remaining
One generator remaining
Three main categories of diversion
Immediate descent necessary
Altitude can be maintained followed by gradual descent
Altitude can be maintained
Essential factors to consider when diverting
Runway length
Runway condition
Approaches available
Fuel remaining
Familiarity of aerodrome
Weather
ATC available
RFF
Traffic congestion at aerodrome
Ideal things to consider when diverting
Engineering support
Passenger handling
Turning circle
Fuel up life facilities
Hotel accommodation for passengers
Approach at airfields without ATC
122.7 frequency
Click mic 7 times for full brightness
5 for med
3 for low
More info in this is found in Atlantic procedures for USA and Canada
Medlink
Can be a good idea to get cabin crew to call them to reduce Chinese whispers
Good medical facilities
CYQX, CYYR, CYXE, CYYT, CYWG
CYYQ has a basic medical centre.
180 degree turns on runway
48m for the 330-300
41m for the 330-200
180 degree turns on 60m rays may only be performed in the runway having first briefed for the FCOM and highlighting any threats associated with lights and lack of markings. 45m runway turns without pads are not permitted.
Planning minima ETOPS alternates
Weather needs to be above planning minima from earliest arrival time to one after after latest expected arrival
Precision APP: ceiling DA/DH +200ft req vis +800m
NP/RNAV/Circle: Ceiling MDA/DH +400ft Req vis +1500m
NB: The above minima is not mandatory for a cat II/III approach but it is recommended.
Non ETOPS must stay within an hour of the nominated aerodrome.
Weather deviation on route
Attempt to get re clearance
If not poss announce LvL POSN and intentions on 123.45 & 121.5
Lights on
Watch for other a/C
Maintain level until 5nm off track then climb descend as appropriate 300ft
Critical Fuel Scenario allows for
Immediate descent toFL100 at 310kts
Descent to 1500ft above aerodrome
Hold for 15 mins at 1500ft
IFR approach, GA and VFR approach.
5%contingency and 2% degradation factor
Fuel for MEL penalties
Fuel for icing systems and APU use
Turbulence
Leave the automatics in
If autopilot disengages and won’t reengage fly wings level at constant pitch
If large thrust changes disconnect A/THR
Set recommended thrust from chart on back of normal checklist
NB: Thrust above MCT at alt ineffective due perf limitations.
Recommended buffet margins
Severe Turb: 2.0g
Moderate Turb: 1.5g
A descent if 1500ft will only increase margin by 0.1g
Do not plan to fly through severe turb
REC max alt in FMS 1.3g. Should plan to fly at least 1000ft below this. Tables much more conservative.
Separation from convective weather
Do not fly less than 5000ft above an area of convective weather
@FL 300 20 mile separation is required
@FL 250-300 15 mile separation is required
@FL 200-250 10 mile separation is required.
