Autoflight Flashcards
(28 cards)
What are the indicated takeoff FMA’s for:
FD/CMD, A/T, Pitch, Roll
@ Initial Pitch and Roll indications
@N1 Selection
@80KIAS
@Rotation (Speed Captured)
@LNAV Selection
@VNAV Selection (FRA)
@Initial Pitch = 8 degrees up, Roll = Wings Level
@N1selection = on FD, A/T = N1, Pitch and Roll = TO/TO
@80KIAS = FD, A/T = THR HOLD, Pitch and Roll = TO/TO
@Rotation = F/D, A/T = THR HOLD, Pitch = the greater of V2 + 15, or Liftoff + 15, Roll = ground track @ 5ft RA.
@LNAV = FD, A/T = THR HOLD, Pitch = TO, Roll = LNAV
@VNAV = *CMD, A/T = N1, Pitch = VNAV SPD, Roll = LNAV
*CMD only if Autopilot selected
What is the minimum altitude for Autopilot engagement after takeoff?
200 feet AGL
good memory tip:
half way between Roll Mode selection (400’) and ground. 400/2 = 200.
What is the minimum altitude for Autopilot Enroute use (except during approaches)?
1000 feet AFE
What is the minimum altitude for autopilot disconnect during non-CAT II or III approach?
i.e CAT I, RNAV, Visual
CAT I 50 feet below DA
RNAV 50 feet below MDA
Visual by 50 feet AGL
Use of aileron trim with autopilot engagement is allowed or prohibited?
Prohibited
How many FCC’s, Autopilot, and Flight Directors are on the 767?
Three each. L, C, R
3 separate FCC’s
3 separate Autopilots
3 separate FD’s
How many FCC’s are required for Autopilot engagement?
Two
What powers the L & C FCC’s?
Normal Operation = Left AC system
What powers the R FCC?
Normal Operation = Right AC system
When the Center FCC is isolated during auto land approaches, what powers the system instead of the L AC?
The HOT Battery Bus through the Static Inverter allows for triple isolation during auto land approaches.
When does T/O mode end on the FMA’s?
At the selection of another pitch/roll mode
With no FD selected on, what mode pitch/roll will the autopilot go into?
Vertical speed and Heading hold
What is the meaning of the yellow AUTOPILOT light?
Autopilot is operating in a degraded condition.
How can the APP, LOC, G/S mode be de-selected?
- Turn off both FD’s, or by
- Selecting G/A mode
Is the TAI reference installed on the 300’s?
No
Altitude (ALT) light comes on at what altitude? What altitude will it extinguish during normal operations climbing or descending?
@ 900’ remaining = ALT on
@ within 300’ = ALT off
What can you expect when you deviate more than 300’ of selected altitude when not in approach mode?
Master Caution lights
Aural “CAUTION” sounds
EICAS “ALTITUDE ALERT” displays
When will the PLI’s be present on the ADI and what does it mean?
The PLI’s will be out when flaps are down and the indication is where stick shaker should occur.
What is the function of the ASA system?
To monitor the A/P when the electrical system is powered
What is the meaning of the top and bottom windows on the ASA?
The top = capability
The bottom = incapability
What is the general meaning of LAND 3?
Fail Operational status with three autopilots working normally.
What is the general meaning of LAND 2?
Fail Passive status indicates a minimum of two autopilots operating normally.
During a crosswind ILS approach with LAND 2 or LAND 3 annunciated on the ASA’s, at what approximate radio altitude does the autopilot enter the runway alignment submode?
500 feet radio altitude
During flare on an auto land landing in the 767-300 at what altitude will the auto throttles retard the thrust levers to idle?
15 feet radio altitude
