Auto Flight Flashcards
How many autopilots are installed?
2
What is A/P engagement criteria?
• no force is being applied to the control wheel
• the STAB TRIM AUTOPILOT cutout switch is at NORMAL.
When can both A/P be engaged at the same time?
Only one A/P can be engaged at a given time unless the approach (APP) mode is engaged. And before 800’
Can you do an autoland with 1 engine inoperative?
YES
What causes the A/P to disconnect?
• pushing either A/P disengage switch
• column or wheel force override
• pushing either Takeoff/Go-around (TO/GA) switch with a single A/P engaged in CWS or CMD;
• below 2000 feet RA or,
• with flaps not up or,
• G/S engaged
• pushing either Takeoff/Go-around (TO/GA) switch with a single A/P engaged in CWS or CMD above 2000 feet RA with flaps not up or G/S engaged.
• pushing either TO/GA switch after touchdown with both A/Ps engaged in CMD (except with LAND 3 or LAND 2 annunciated)
• pushing an illuminated A/P ENGAGE switch
• pushing the A/P DISENGAGE bar down
• activating either pilot’s control wheel trim switch (except with LAND 3 or LAND 2 annunciated)
• moving the STAB TRIM AUTOPILOT cutout switch to CUTOUT
• for a column and/or wheel force override of a single or dual channel CMD engaged autopilot, in approach or non-approach phase of flight. The AFDS will maintain the active pitch and roll modes with flight
director guidance.
• either left or right IRS system failure or FAULT light illuminated
• loss of electrical power or a sensor input which prevents proper operation of the engaged A/P and mode
• loss of respective hydraulic system pressure.
What would be the indication that the 2 FCCs are operating in independent mode and when does it happen?
Land 3
After pressing TOGA while conducting a takeoff how many degrees pitch up is the flight director showing?
At 60 KIAS, the F/D pitch commands 15 degrees nose up.
When will LNAV / VNAV engage on takeoff?
Armed but not engaged
If engaged in CWSp and CWSr, what attitude will the A/P hold after releasing the control wheel?
When control pressure is released, the A/P holds existing attitude.
What does a second press of the TOGA switch on takeoff or go-around do?
Thrust levers advance to full go around thrust
When is climb thrust automatically active?
Automatic reduction to climb thrust occurs upon reaching the selected thrust reduction altitude
On a go-around, what rate of climb is targeted by the thrust and what degree pitch up will the flight director show?
thrust advances toward the reduced go–around N1 to produce 1000 to 2000 fpm rate of climb
F/D pitch commands 15 degrees nose up until reaching programmed rate of climb.
After achieving this desired go around climb, what will the flight director command in terms of pitch?
F/D pitch then commands target airspeed for each flap setting based on maximum takeoff weight calculations
Does the A/P or autothrottle disconnect with a windshear warning?
NO
What overspeed/underspeed protections are there?
Placard limit reversion
Minimum speed reversion
