AUTOFLIGHT Flashcards
- The autopilot system can detect the degradation of a specific autopilot mode. What indication(s) result when an engaged mode degrades?
1.
The autopilot remains engaged in an attitude-stabilizing mode based on inertial data
A persistent condition is annunciated by an amber line drawn through the affected Flight Mode Annunciation (FMA)
Further degradation results in EICAS caution message AUTOPILOT
- What does an AFDS status annunciation of LAND 3 indicate?
- Three autopilots are engaged and operating normally for an automatic landing. The autopilot system level of redundancy is such that a single fault cannot prevent the autopilot system from making an automatic landing (fail operational).
- Changes in autoland status below 200 feet, other than a transition to NO AUTOLAND are ___.
- Inhibited
- How does the autothrottle apply thrust when operating in the THR mode?
- The auto throttle applies thrust to maintain the vertical speed required by the pitch mode.
- What flight envelope protection is provided by the autopilot?
5.
Bank angle
Stall (above 500 feet)
Overspeed
- When does the auto throttle disconnect automatically?
- The auto throttles disconnect automatically when:
A fault is detected in the engaged autothrottle mode.
Either reverse thrust lever is raised to the interlock position.
Both engines are shut down.
- When the CLB CON switch on the MCP is pushed in flight, what is accomplished?
- With two engines operating, changes the engine thrust limit to the FMC selected climb thrust.
With only one engine operating, changes the thrust limit to maximum continuous (CON).
- The MCP IAS/MACH window displays ___ knots when power is first applied.
- 200
- What is accomplished by pushing the LNAV switch on the MCP?
9.
Arms, engages, or disarms LNAV as a roll mode.
Displays LNAV in white (armed) on PFD roll FMA when armed. Previous roll mode remain active.
LNAV engages if aircraft is above 50 feet radio altitude, within 2.5 NM of active leg, and within path capture parameters of ground speed, intercept angle, and bank angle to active leg. When engaged, displays LNAV in green on PFD roll FMA.
With LNAV armed and aircraft not on heading to intercept active leg, displays NOT ON INTERCEPT HEADING in CDU scratchpad.
Selection of LNAV when an active route is not available displays NO ACTIVE ROUTE in CDU scratchpad.
- After localizer and glideslope capture, the localizer and glideslope modes can be disengaged only by what?
10.
Disconnecting the autopilot and turning both F/D switches to OFF
Engaging the go-around mode
If above 1500 feet, by de-selecting APP (roll and pitch revert to default modes)
- During an approach after LOC and G/S capture, how do you disengage the LOC and G/S?
11.
After localizer and glideslope capture, these modes can be disengaged by one of the following methods:
Disengaging the autopilot and turning both flight directors off
Engaging the go-around mode
If above 1500 feet, de-selecting APP (roll and pitch revert to default modes)
- Which of the following Flight Mode Annunciations (FMAS) indicate that the Autopilot Flight Director System (AFDS) is commanding the Autothrottle system to set thrust to maintain a vertical speed required by the active pitch mode?
- THR
- Select the best answer. With VNAV ALT engaged and the IAS/MACH window closed, changing the altitude in the Mode Control Panel ALT window and pushing the FLCH switch will cause which of the following to occur?
- THR and FLCH SPD annunciate and IAS/MACH window opens.
- Which Flight Mode Annunciation (FMA) indicates that the throttles are moving to match thrust to the green thrust limit annunciated on the primary EICAS?
- THR REF
- When is the TO/GA mode armed inflight?
- Unannunciated, but armed when flaps are extended or glideslope is captured.
