Autoflight Flashcards
What are the two separate functions of the Pimus Automatic Flight Control System?
Flight director and autopilot
How does the autopilot receive pitch and roll commands?
The flight guidance system provides input to position the command bars, which are followed by the autopilot
Where are the selected modes shown on the flight guidance controlled?
At the top of the PFD
How can the autopilot be instructed to follow the No. 2 com and bar, instead of No. 1?
The couple button on the FGC
What does the Low Bank mode do?
It reduces bank angle from 27° down to 14° when in HDG mode. The Low Bank mode is automatically selected when climbing above 25,000’ and automatically cancelled when descending below 24, 750’
Which mode is utilized for capturing VOR radials, LOC approaches, FMS navigation, and GPS approaches?
NAV
Which mode is used for ILS and VOR approaches?
APP
What caption will appear next to the couple arrow on the PFD when NAV mode is selected using FMS navigation?
NAV
What is the default lateral mode?
Heading Hold mode (ROL)
Which button allows the plot to climb or descend at a desired airspeed?
SPD
What are the preset climb speeds/rates of descent associated with the FLC button?
- For climbs: 240kts below 10,000’, then gradually increasing to 270kts above 12,000’ until reaching 17,377’ where it changes to 0.56 Mach
- For descents: 2,000 FPM down to 12,000’, then gradually reducing to 1,000 FPM below 10,000’
How is a desired rate of climb/descent set?
By pressing the VS button and setting the rate using the speed set knob
How is desired altitude for level-off set?
By using the ASEL knob. It is then shown at the top of the altitude tape.
What are the normal flight guidance control selections for takeoff?
Takeoff sub-mode and HDG
What pitch setting is shown when the takeoff sub-mode is selected?
14° nose up with flaps set 9° or 13° nose-up with the flaps set at 18°
How is the heading bug synced to the current heading?
By pressing the center of the heading select knob
What color indicates an armed lateral or vertical heading?
White
What color indicates a captured lateral or vertical mode?
Green
What does an amber TKNB message on the PFD indicate?
The turn control knob is out of the center detention position, and autopilot is disengaged
How can the autopilot be disconnected?
By pressing the autopilot disconnect button or by activating the pitch trim switch
If the autopilot is engaged, will pressing the pitch trim button disengage the yaw damper?
No, only the autopilot
What does the touch control steering (TCS) button do?
It allows maneuvering of the aircraft without disengaging the pilot. If a new pitch attitude has been established, the autopilot will maintain it when the TCS button is released. Lateral control will revert to the previously selected mode.
What does pressing the center of the speed select know do?
It toggles the airspeed indication at the top of the airspeed tape between IAS and MACH
When an armed mode transitions to a capture mode, how is the transition shown?
By a box around the mode for 5 sec
What is shown on each side of the couple arrow at the top of the PFD when established on an ILS localizer and glide slope with the approach mode selected?
LOC and GS
Is a single engine go-around with the autopilot engaged authorized?
No. It is prohibited
Approach mode selection during localizer capture is allowed ONLY under what condition?
When the aircraft is inbound
What will the indications on the PFD be upon pressing the TOGA buttons on a normal missed approach?
The command bars will move to +10° and ROL GA will be shown at the top of the PFD
What is the maximum altitude for engagement of the autopilot?
FAA 500’ AGL; EASE 1,000’ AGL
What is the minimum disengagement altitude for the autopilot on a non-precision approach?
200’
What is the minimum disengagement altitude for the autopilot on a non-precision approach?
MDA
What does the Heading Select mode do?
It allows the flight director to track the heading bug as set by the heading select knob
What is the purpose of the VOR Approach mode (VAPP)?
It provides the same capabilities as the VOR NAV mode but with higher gain for operation close to the station
Which mode allows the aircraft to climb or descend to a predetermined altitude and then level off and maintain altitude?
Altitude Preselect (ASEL)
