UPRT/Unreliable speed/Stabilisation Flashcards
When should a crew consider applying the unreliable speed indication procedure?
(i) Action line displayed on ECAM
(ii) Crew suspects an erroneous indication
With erroneous speed, does the stall warning still apply?
Yes, based on alpha
If the crew has applied the mem items for unreliable speed, what should be done with the pitch?
Level off
Use pitch and thrust tables in QRH
Below what height should all ADRs be switched off with unreliable speed?
FL250 - activates the BUSS
How many ADRs should be left on above FL250?
1
Will the bird be reliable with unreliable speed?
Possibly if good ADR source, not if source is unreliable
What law is the ac in with the BUSS?
Alternate
What is done to the ac config with unreliable spped?
If FLAP FULL then FLAP 3
If Gear down then Gear up
What should be done with the automation with unreliable speed?
AP/FD OFF
A/THR OFF
What are the stable approach criteria for an ILS?
1/2 Dot LOC
1 Dot GS
What is the speed requirement for a stable app?
+15 to -5 Kt
What is the bank limit for a stable app?
15 degrees max (at 400 ft for a circling app)
What call is made for fuel priority to ATC?
“MINIMUM FUEL” (ICAO)
Used when likely to land below min reserve fuel
When is the SINK RATE call made by PM?
Descent rate exceeds 1200fpm
When is the bank call made
7º
When should the speed call be made?
speed exceeds -5 to +10 kts
When is the pitch call made?
Pitch lower than 0º or greater than +10º
When is the pitch call made on a GA?
Pitch lower than +10º or higher than +20º
What is the universal recovery technique?
Push
Bank
Thrust
Recover
Why should you never do a rolling pull recovery from an unusual position?
It will put far to much stress on the wings
What thrust should be used on a stall recovery?
“As appropriate” thrust
How long must the takeover PB be pressed to disable the other sidestick?
40 secs
What action will reactivate a disabled sidestick?
Pressing either of the takeover PBs
If both pilots press and hold their takeover PBs together, which one gets priority?
The last one to press his takeover PB
What will any spoiler extension do at top of climb?
Prevent the engagement of A/THR soft mode
When does AoA protection become active?
At alpha prot
Why do Vα MAX and Vα PROT move up when in an AP level turn while GDS and VLS remain static?
Vα PROT and MAX are affected by the increase in load factor, whereas GDS and VLS are affected by aircraft weight.
What does the ß target provide?
Minimal aircraft total drag and therefore best climb performance
Must the max eng out accel alt be observed if only flex thrust used
Yes
