How many fire bottles for each cargo compartment?
Two fire bottles with two discharge heads.
How long after the AGENT 1 discharge will the crew have to discharge AGENT 2?
60 minutes
CARGO SMOKE - A flow metering unit system controls the discharge of bottle 2 in approximately…
140 minutes
CARGO SMOKE - the combination of both bottles ensures sufficient agent concentration for…
200 minutes
ELEC EMER CONFIG - AIR CONDITIONING - as cockpit and cabin temperature control is lost, it is recommended to…
open the cockpit door.
The 60 minute circle divergence distance for A321 is:
400 NM
After entering Oceanic Airspace, ATC must be advised if speed changes by
+/- 0.02 Mach
After entering Oceanic Airspace, ATC must be advised if waypoint crossing time changes by
More than 2 minutes from the last estimate given to ATC.
What is SLOP and what offset is used?
Strategic Lateral Offset Procedure is used in the NAT Region.
Th offset should be between 0.1NM and 2NM, RIGHT of track.
An adequate airport is an airport that the aircraft can safely divert, in case of emergency and:
- Satisfies the aircraft’s performance requirements
- It is available at the expected time of use
- Landing authorisation is granted
- It has ground operational services (ATC, Meteorological and information offices, lighting)
- At least one instrument approach (ILS, VOR, NDB…)
- RFFS category at least CAT 4.
LIMITATIONS
- The time capability of the cargo fire suppression system is…
- The time capability of all other ETOPS significant systems is…
- 195 min.
- 195 min.
The ETOPS Critical Point is the point, along the route, for which the difference between the…
… standard fuel expected to be on board (FUEL TO CONTINUE) and the required ETOPS diversion fuel (FUEL TO DIVERT) is minimum or negative, thus requiring the carriage of additional ETOPS fuel reserves.
MW point checks includes:
- time
- coordinates
- wind
- temperature
- FOB
- FU
- FF
ETOPS critical fuel planning - diversion fuel is defined as:
- Fuel burn-off from the critical point to the end of descent, 1500ft above en-route alternate
- Contingency fuel:
5% of the above fuel, to allow for WIND DATA ERRORS
5% of the above fuel, to account for DECREASE FUEL BURN PERFORMANCE - 15 minutes holding at 1500ft at GREEN DOT
- First approach and landing
- MEL/CDL effect
- APU fuel consumption (160kg/h)
- Forecasted SEVERE ICING CONDITIONS
Suitability time window is the period commencing…
…at the EARLIEST POTENTIAL TIME of LANDING at the considered en-route alternate aerodrome and ENDS:
- ONE HOUR AFTER the LATEST ESTIMATED TIME OF ARRIVAL at this aerodrome.
Unless reliable icing forecast is available, icing may be presumed to occur when the…
- TAT (temperature on airplane surface) is LESS THAN 10°C at any point between the most critical point and ETOPS alternate at FL100
- if OAT is between 0°C and -20°C with a Relative Humidity of 55%
WX avoidance - if deviation < 5NM:
- Deviate away from OTS or route system
- REMAIN at level assigned
- Look out for traffic (visually and TCAS)
- Switch ON ALL LIGHTS
- Communicate intentions and position at SUITABLE INTERVALS (Callsign, FL, position) on active frequency and 121.500 or 123.450
WX avoidance - if deviation >= 5NM:
- Deviate away from OTS or route system
- Initiate LEVEL CHANGE (South - climb, North - descend)
- Look out for traffic (visually and TCAS)
- Switch ON ALL LIGHTS
- Communicate intentions and position at SUITABLE INTERVALS (Callsign, FL, position) on active frequency and 121.500 or 123.450
CONTINGENCY PROCEDURE - apply in case of:
- WX avoidance
- En-route diversion (due medical reasons)
- Loss/reduction of navigation capability

SOP - BEFORE ETOPS ENTRY POINT
- ETOPS ‘BEFORE ENTRY POINT’ checklist
- Obtain alternate WX (apply normal minima to valida suitability)
- Check A/C system status for ETOPS
- Update winds in FMS
- Set assigns Mach
- LOGON CPDLC
- Evaluate potential en-route diversion airports WX/services
- Use FMS-ETP page to enter most suitable airports and use PROG page with city pair
- Verify next leg track and distance
- HF/SELCAL check
The technical criteria governing a re-routing or diversion decision can be classified into four categories:
- Loss of MNPS capability (before entering the MNPS area)
- ETOPS alternate becomes unavailable (e.g. WX below minima BEFORE reaching EEP)
- Failure cases requiring a diversion (LAND ASAP)
- Failures that cause an INCREASE in FUEL CONSUMPTION
