Flight Controls Flashcards
What kind of flight control system does the aircraft have?
A functionally distributed Fly-by-wire control system
Two basic modes of operation
Normal (NM) and Direct (DM)
When will the flight control system automatically revert back to Direct mode?
When Normal mode is not possible due to multiple system failures
Is flight under Direct mode recommended?
No, it should be avoided since some protection functions are lost
What happens if the AP/PTY button is pressed and released?
Auto pilot is disengaged
What happens if the AP/PTY button is pressed and held for longer than a second?
Exclusive control given to the side stick while it’s pressed in and priority annunciation is activated
If one side stick has been latched out, how can exclusive control be removed?
By pressing either sides priority button
What happens if dual side stick input occurs and priority has not been requested by either?
Tactile warning in each stick, oral warning, PFD flag are triggered.
The inputs are algebraically summed
Is sidestick controller priority available in Direct Mode?
No, normal mode only
With AP engaged, Touch Control Steering (TCS) does what?
Allows pilot to manually control airplane while AP is engaged
During manual flight with flaps 3 or full, gear down, AP off, what does the Touch Control Steering (TCS) button do?
Resets TCS trim speed bug
Pulling the speed brake level activates what?
Deploys multifunction spoilers as speedbrakes
What are the multifunction spoiler angles when used as speed brakes?
Stowed is 0, FULL is 30
When can the Pitch trim switch be manually operated?
On the ground or in Direct mode
What button is used to recover Normal Mode or revert to Direct Mode is Norm is malfunctioning?
FLTCTRL NORMAL MODE button
When is a manual switch to DM inhibited?
FCS protection engaged: Low or high speed protection, AOA protection
On the Flight control synoptic page, an amber actuator status means…
Plane is in Direct Mode and at least one actuator is engaged
When is side slip target presented by a blue side slip skid indicator?
One engine inop during TO, climb, or GA
Where is the Low Speed Awareness (LSA) located?
Adjacent the speedtape
Where are the Pitch Limit Indicators (PLI’s) located
On the ADI
List the 3 LSA bands in NM and what they indicate
Vss - top of white tape - low speed protection function
Vaoa - top of Amber tape - AOA limiter function activation
Vlim - top of red tape - max allowable AOA airspeed
Do the Vss and Vaoa/Vlim behave the same in turns and other maneuvers?
No, Vss goes off speed and the other two go off AOA
Do Vaoa and Vlim increase with load factor?
Yes
Is the AOA limiter function available in DM?
No
