Autoflight Flashcards
How many flight guidance modules are there in the AFCS?
Two.
Where is the Flight Mode Annunciator (FMA) located?
On the top of the PFD.
Which of the following would you see on the Flight Mode Annunciator (FMA) display?
AP or TCS engage status, AP/YD status messages, mismatch and mistrim messages, FD selected targets, lateral active and armed modes, vertical active and armed modes, FD abnormal condition messages, HSI, dual FD or CAT II fail indications, AFCS failure messages.
T or F: Flight Guidance Module (FGM) 1 is the master channel.
True.
T or F: Flight Guidance Module (FGM) 2 is the slave channel.
True.
T or F: the Flight Guidance Modules operate independently and act as the “brains” of the AFCS.
True.
The autopilot and the yaw damper functions require ____ FGM(s) to be operational.
Both.
T or F: the flight director displays both lateral and vertical visual guidance for the crew on the PFD.
True.
T or F: primary controls of FD modes and selections are provide by the Flight Guidance Control Panel.
True.
When flight guidance modes are active, what color are they displayed in on the PFD?
Green.
When flight guidance modes are armed, what color are they displayed in on the PFD?
White.
When do flight guidance modes that are armed become active?
When certain conditions are met.
When an armed flight guidance mode changes to active, it is annunciated by the display changing to reverse green video for ____ seconds.
Five.
T or F: dual FD mode is a sub-mode of the ILS approach mode.
True.
If pilots activate the AP with no AFCS commands set and are in a bank greater than 6 degrees, what does the system default to?
ROLL HOLD.
Which of the following is a basic lateral mode?
ROLL HOLD, WING LVL, HDG HOLD.
T or F: when pilots switch to HDG mode, the AP flies the heading the aircraft is currently on.
False, it will be the heading bugged.
T or F: when pilots enter HDG mode, the AP flies the heading the heading bug is set to, even if it is not the current heading.
True.
T or F: when in VOR mode, the FD tracks VOR radials.
True.
When in VOR mode and flying over a VOR, what does the sub mode do to keep on course?
Maintains a heading of selected VOR course.
When is LOC mode used?
During localizer based instrument approaches.
T or F: the AFCS has a localizer back course mode.
True.
When climbing or descending, pilots will get an aural tone how far from the altitude set in the altitude alerter?
1,000 feet.
T or F: in IAS mode, the pitch is adjusted to maintain desired airspeed.
True.
In VS mode, pitch is adjusted to maintain ____.
A selected vertical speed.
How is the GA mode activated?
Pressing either of the two go-around switches on the power levers.
T or F: if the yaw damper is inoperative and on MEL, the autopilot will still engage.
False.
T or F: the yaw damper can be on without the AP but the AP cannot be on without the YD.
True.
When does the autopilot automatically disengage?
If any engagement logic is not met:
- aircraft is still airborne,
- attitude is within limits,
- ADC and AHRS inputs are valid and agree,
- yaw damper is available or already engaged,
- autopilot disengage annunciators are not displayed.
The Tactile Control Steering (TCS) allows the pilot to accomplish what?
Gives crew manual control without disengaging the autopilot.
If one flight guidance module fails, which system will remain operative with the remaining FGM?
The flight director.
When the HSI SEL is pressed with flight guidance modes and FD present, what happens?
Changes which side the FDs receive nav, heading, course, and AHRS data from; clears all FMA modes and removes FDs from view.
What does the VOR OS lateral mode indicate?
The aircraft is transitioning over the tuned VOR station and the AFCS will maintain a constant heading.
Which button on the AFCS panel is pressed to arm the LOC mode?
NAV or APPR.
Which of the following is the normal pilot action to ensure the AFCS captures a selected altitude during climb or descent?
Select the ALT SEL switch.
T or F: the aircraft must be airborne to engage the autopilot.
True.
When the autopilot is engaged, and the red A/P DIS on the yoke is pushed once, it disconnects the autopilot. Pushing it a second time does what?
Cancels disconnect message.
