Q

Do reversers affect your crosswind limits?

A

Only when asymmetric reverse thrust is used.

Reduce crosswind limits by 5 kts on WET or CONTAMINATED runways.

55
Limitations on the use of reversers during RTO?
-ER: Shall contact maintenance control to see if maintenance inspection is needed before another takeoff -300: can’t takeoff until after maintenance action.
56
Max engine power (N1) for ground ops in strong tailwind and crosswind

58
Which flight control mode can you takeoff in?
Only in normal mode
59
Max alt with flaps extended
20,000 ft
60
Do you need to do Cold temperature altimeter correction to EO ACCEL HT?
For takeoff. NO. OPT EO ACCEL HT are valid for low temperatures. In case of discrepancy between OPT or Port page EO ACCEL HT, use the greater of. OMA 8.1.1.4.3
61
Do you need to do a correction to the Missed approach EO ACCEL HT with temperature of 0°c or below?
YES OMA 8.1.1.4.3
62
Can you use LNAV/VNAV for the approach into BGTL?
No, QFE need to be used and LNAV / VNAV USE with QFE is prohibited
63
What is the fuel SG limit?
SG between 0.73 and 0.85 kg/litte
64
Can you have centre tank fuel if main tanks are not scheduled to be full?
NO. Residual centre tank fuel limit of 1300kg.
65
-300: how much additional fuel is required if centre tank fuel is required?
320kgs of reserve fuel must be added to the centre tank fuel load. **BUT** only if centre tank fuel is required for the mission. (Tankering is not fuel that is required for the mission)
66
-300: Fuel imbalance limits between main tanks
Main tank fuel exceeds 51.7T -> 1.3T Main tank fuel less than or equal to 22.6T -> 2T Interpolate between 1.3T-2T between 51.7T and 22.6T
