Helicopter Performance Quiz

In cruise, an extreme aft longitudinal centre of gravity:

• Brings the cyclic stick closer To its forward stop And increases the stress in the rotor head.

• Moves away the cyclic stick from its forward stop and increases the stress in the rotor head.

• Brings the cyclic stick closer to its forward stop and decreases the stress in the rotor head.

• Moves away the cyclic stick from its forward stop and decreases the stresses in the head rotors.

A helicopter in the hover that requires an excessive amount of aft and right cyclic may indicate the centre of gravity is too far:

• Forward and laterally too far To the left.

• Aft and laterally too far to the left.

• Aft and laterally too far to the right.

• Forward and laterally too far to the right.

Following an engine failure en-route when not visual with the surface, the helicopter must clear obstacles within a 5nm domain either side of intended track. The flight conditions improve to VMC and the surface is in sight. What are the dimensions of the obstacle domain?

• 900m Semi-width.

• 600m semi-width.

• 10R.

• 300m semi-width.

Please refer to the annex. Given a gross mass of 6300 kg and an OAT of -5° C, at what pressure altitude can the helicopter maintain a hover IGE with one engine inoperative?

• 7500 ft.

• 6250ft.

• 5250 ft.

• 5500 ft.

ATC request that a descent from 6500 ft to 4000 ft in 8.3 NM. TAS is 154 kt. The rate of descent needed is

• 618 ft/min.

• 802 ft/min.

• 642 ft/min.

• 773 Ft/min.

If carrying out a balked landing the minimum ROC at 200ft is:

• Minimum ROC does not apply until 1000 ft.

• 150 ft/min.

• 100ft/min.

• 50 ft/min.

With reference to CAP758 figure 3.44. Determine the distance D4 and the gradient required for the TETH to climb from 200 ft to 1000 ft given: PA 8000 ft OAT 0°C Mass 7000 kg Wind 20 kts HW

• 180 m/600 ft/8%.

• 1000 m/3000 ft/6%.

• 3000m/10000 ft/8%.

• 250 m/750 ft/12%.

In level flight, in performance class 1 and 2, with one engine failed and the others operating, at 1000 ft above any obstacle along the route, the weight of the helicopter must allow it to climb:

• At Least 50 ft/mn.

• At least 100 ft/mn.

• At least 150 ft/mn.

• At no definite value by the authority.

In performance class 1, with one engine failed and the others operating normally, the helicopter's weight at the estimated time of landing must be such that a rate of climb of at least 150ft/mn at 1000 ft above the altitude of:

• The destination heliport.

• The take off heliport.

• The alternate heliport.

• The Destination or alternate/diversion Heliport.

The "take-off path" is the horizontal and vertical profile calculated:

• With AEO to 1000 ft.

• With AEO to 1500 ft.

• With OEI to 1500 ft.

• With OEI To 1000 ft.
