rudder input will cause left roll input. (This may be why the airplane roll is
sensitive. Aileron input coupled with rudder input compounds the aileron input.)
91.The airplane does not have a flight-control gust lock, and you are not required to
secure the control yoke with a seat belt when the airplane is tied down. Why not?
Because the rudder, aileron and elevator trim spring cartridges have sufficient
power to act as a gust damper.
92.What are the small tabs on the elevator, rudder and right aileron? Ground
adjustable trim tabs that are factory set and do not normally require adjustment.
93.A conical trim button (called a “coolie hat”) activates the aileron and elevator trim
motors when moved left or right or up or down. When pushed down, it?
Disconnects the autopilot if engaged.
94.How do you position the elevator trim and the aileron trim to the neutral position?
Elevator: Align the yoke’s reference ,arl with the metal tab that’s attached to the
instrument panel bolster- the rounded portion that extends across the cockpit
beneath the instrument panel. Aileron: Align the force-and-aft line that’s etched
on the control yoke with the centering indication that’s marked on the bolster.
95.If the elevator control system or aileron control system failed due to something
other than a jammed elevator or a jammed aileron, how could you control the
airplane? Use the elevator or the aileron trim control system.
96.What is the yaw trim system? A spring cartridge attach to the rudder control
system that provides a centering force whenever the rudder is deflected. It is
ground adjustable only.
97.What backup flight instruments are available if the PFD fails? Altimeter, airspeed,
attitude indicator, and magnetic compass.
98.Does the airplane have a traditional turn coordinator? Yes, but it’s out of view
behind the right instrument panel bolster and it’s only used by the autopilot.
99.What is the primary heading source for the multifunction display? The PFD.
100. What adjustments can be made for the front seats? Fore and aft and
seat-back tilt.
