10. Using Fig. 16-32, an acceptable container pressure at 20°C would be
A. 300 psi.                         C. 600 psi.
B. 400 psi.    D. 700 psi.

Solution

8) When is it permissible to clamp a wire bundle to a fuel line:

D. It’s never permissible

Beacuse, it is impossible to physically separate fuel lines from electrical wire bundles, locate the fuel lines below the wiring and clamp the wire bundle securely to the airframe structure.They lead to leading to indirect damage,
such as arcing and chafing.

9)Continuous-flow rebreather oxygen regulators are appropriate for:

B.high-flying military aircraft.

The oxygen masks that automatically drop from the overhead compartment of a jet transport aircraft in the event of cabin depressurization are of the rebreather type. The plastic cup that fits over the mouth and nose has a check valve in it, and the plastic bag attached to the cup is the rebreather bag.
