Question #3
An aircraft's VOR receiver shows a centered CDI and a TO indication with the OBS set to 090°. On which radial from the station is the aircraft located?
Correct answer: C
Explanation
A centered needle with TO and 090° selected means the aircraft is on the course to the station that leads east, so it is west of the station on the 270° radial. Radials are measured outbound from the station, so 090° is the reciprocal and the wrong choice.

Question #5
When an airplane flies within about one wingspan of the surface, ground effect produces which change at a given angle of attack?
Correct answer: A
Explanation
Near the surface the ground restricts wingtip vortices and downwash, which reduces induced drag. This is why an airplane may float on landing or lift off at a lower speed than it can sustain out of ground effect.

Question #6
The main reason for a maximum zero fuel weight limitation on a transport airplane with wing-mounted fuel tanks is to limit
Correct answer: C
Explanation
Weight in the fuselage bends the wings upward at the roots, and fuel in the wings partly offsets that load. Capping the weight excluding fuel controls the wing-root bending stress. Landing gear loads are controlled by the separate maximum landing weight.

Question #8
A dispatcher is briefing a crew on a fast-moving cold front with unstable, moist air ahead of it. Which weather is most likely along the front?
Correct answer: C
Explanation
A fast-moving cold front lifts unstable air abruptly, producing a narrow line of cumulonimbus with heavy showers, gusts and possible thunderstorms. Steady rain from nimbostratus well ahead of the boundary is typical of a slow-moving warm front, which is the tempting wrong choice.
