What’s VLS?
Lowest selectable speed
What’s V alpha prot?
After entering the protection range (amber&black strip) the speed the nose will pitch for when releasing side stick
What’s V Alpha Max?
Lowest speed the aircraft will reach with full back side stick deflection (aoa limit)
What’s A floor?
The AOA between Alpha prot and Alpha max where Toga thrust is set even if A.T is off
Above which Alt. Should you avoid Exped* climb?
FL250
Auto pilot disconnection Heights on FLS VS Final App?
FLS: 200’ (FDs can stay on if runway is anchor point)
Final App: highest of Minima or 250’ ( FDs off)
When can you use “committed to stay procedure”?
Delay is of traffic nature (not wx)
Actual+Taf AAM at dest.
2 separate inst. RWYs (unless alt is also SGL RWY)
TWR/APP are notified of BINGO fuel/time
2D approaches
Nav/Loc/Trk FPA
Early stabilized: Vapp @ FAF
AP+FDs off bird on @ 250’
Flap speed extension recommendation
-15 from LIM to avoid flap wear
Normal ILS intercept envelope?

+/-8°
At what height does app capability upgrade from CAT I to CAT II/III?
Below 5000’ AGL
Early/untimely “Flare” mode
GA or AP+FDs off & continue raw data+visual
Dual RA Fault:
Early stabilized
REGULAR FD ON LOC/NAV+VS mode
Landing flaps 3
Add 5 KTS to Vapp if S/E
Flaps 3 established on descent and then Gear down (EMER cancel LG warning)
LG DOWN - Direct Law+ AP Off
No APP mode - LOC avail
No Auto callouts - PM reads out loud
Dual FCU:
Loss of AP/AT/FD and TRK bug
No mode on FMA
Both PFD use 1013 QNH, only STBY has control of QNH
Minima can be set as RA alt
Landing Flaps 3
BIRD ON
use bird using white lines on horizon, cardinal heading
Intercept at 20° max, on a very long final
Continuous scan of dagger vs green diamond
If S/E - use FO to setup power (wt+10%) increase Vapp 5 KTS
Min Icing speeds
Wing A/I+Clean, 1, 2, 3 - VLS +10
Wing A/I+Full - VLS+5
No Wing A/I - VLS + 10 / G.Dot
