Question 1

Unmasking in flight. This type is used when the ACFT has forward speed and can best be described __________________________________.

Answer 1

As a pop up and peek at desired point of observation.

Question 2

Aircrew coordination patterns begin with the accomplishment of what?

Answer 2

Crew level pre-mission planning, rehearsal, and AAR’s

Question 3

While performing vertical unmasking what is the command using standard words and phrases for the following:

A. Change altitude up/down:
B. Maintain present position:
C. Conceal/position above terrain:
D. “Hover aft” followed by distance:
E. “Hover forward” w/distance:
F. Horizontal movement and L or R:

Answer 3

A. Come up/down
B. Hold
C. Unmask/Mask
D. Move back
E. Move forward
F. Slide

Question 4

Each helicopter has a static rollover angle that, if exceeded, will cause the ACFT to rollover. The static angle is based on CG and pivot point. This angle is described as being the point where:

Answer 4

The ACFT CG is over the pivot point, exceeding the critical angle.

Question 5

Certain factors influence dynamic rollover including right skid down, left pedal inputs (single rotor ACFT), the effect of pilot input (lateral motion) in a rigid rotor ACFT, lateral loading (asymmetrical loading), crosswind, and high roll rates. Smooth and moderate collective inputs are most effective in preventing dynamic rollover as it: _______________________.

Answer 5

Reduces the rate that lift/thrust are applied
