159. When pushing the airplane backward, must the tow bar be installed? Yes, to
keep the nose wheel from turning abruptly.
160. Can you push on the propeller or the horizontal or vertical tail surfaces when
moving the airplane? No, push on the wing roots.
161. If the airplane is towed by a vehicle, nose wheel turning is limited to: 90°.
162. What power setting should be used for taxiing? The minimum power needed
for forward movement. Excessive braking may result in overheated or damaged
brakes.
163. How can you make a minimum radius turn during ground handling? Rotate
the airplane around either main landing gear by pressing down on the fuselage
just forward of the horizontal stabilizer in order to raise the nose wheel off the
ground and pivot the airplane.
164. What are the proper tire pressures? Nose wheel: 40 psi. Main wheels: 53 psi.
165. Installation of the oil dipstick can be difficult. How should you do it? Point the
dipstick’s finger loop toward the airplane’s nose or tail, and allow the dipstick to
rotate as you push it into the engine.
166. When cleaning the windshield and windows, what hand motion should you
use? Linear- straight back and forth. Circular motion causes spirals in the
plexiglas which makes those scratches much more apparent when flying.
167. How should you clean the electronic display screens (PFD and MFD)? Gently
wipe the display with a clean, dry cotton cloth. Moisten a clean, cotton cloth with
Optiimax LCD Screen Cleaning Solution, wipe screens in one direction moving
from top to bottom, and then wipe the display clean with a clean, dry, cotton
cloth.
