The Hover

Question 1

The down wash velocity during the hover is increased when gross weight is (greater, smaller) and density altitude is (higher, lower)

Answer 1

Greater
Higher

Question 2

When hovering in ground effect, rotor drag is ——- than when hovering out of ground efffect but total rotor thrust required is (more, the same , less)

Answer 2

Less
The same

Question 3

For a given power limitation, the less the gross weight of the helicopter, the ——- the maximum skid height during hover in ground effect.

Answer 3

Higher

Question 4

Maximum skid height for hover in ground effect is ——- when power available. Is less.

Answer 4

Reduced

Question 5

When, during the hover, the front of the disc is in ground effect and the rear is not, the helicopter tends to (pitch,yaw,roll) ( down, to the right, to the left)

Answer 5

Roll
Right

Question 6

When you hover close to obstructions, recirculating becomes evident when you require (higher, lower) collective settings to maintain hover height and (the higher, the lower) the hover height the less the degree of recirculation.

Answer 6

Higher
Higher

Question 7

During the approach to a high altitude landing site you note the rrpm is near the bottom of the green range. If you do not (increase, decrease) rotor rpm at this stage,the rate of descent will ——- as you reduce your airspeed and the rrpm is likely to (increase, decrease) further

Answer 7

Increase
Increase
Decrease

Question 8

Your collective lever is full up as you approach your landing site at maximum gross weight. As airspeed decreases, reserve power available becomes (more, less) and the rate of descent ——-. If the rrpm continues to reduce your best course of action is to maintain at least ——- speed and ——- the approach.

Answer 8

Less
Increase
Translational
