ATA 55 Flashcards
The horizontal stabilizer attached to the airplane by meaning of (B1)
a. 02 pivot fittings at the rear spar and 01 stabilizer trim actuator at the front spar
b. 02 pivot fittings at the rear spar and 01 stabilizer trim actuator at the upper fitting
c. 02 pivot fittings at the front spar and 01 stabilizer trim actuator at the rear spar
What is the secondary structure attached to the horizontal stabilizer (B1)
a. leading edge
b. elevators
c. tip fairing
d. All above a, b and c
What is the main structure of the horizontal stabilizer (B1)
a. aluminum
b. carbon fiber reinforced composite
c. glass fiber reinforced composite
What is correct for the pivot fittings of the horizontal stabilizer (B1)
a. the left and the right fitting are the same
b. the left and the right fitting are interchangeable
c. the left and the right fittings are not the same, the right fitting can move laterally because of the difference of the thermal expansion between the composite stabilizer and the metal fuselage

b. of the conducting strip on the elevator surface
c. of the ground cable connected to the conducting strip
d. b and c
What is the main structure of the vertical stabilizer (B1)
a. aluminum
b. carbon fiber reinforced composite
c. glass fiber reinforced composite
What is the secondary structure attached to the vertical stabilizer (B1)
a. leading edge
b. rudder
c. tip fairing
d. All above a, b and c
Where is the HF antenna located (B1)
a. on the vertical stabilizer tip fairing
b. on the vertical stabilizer side panel
c. on the vertical stabilizer leading edge panel
