In PC3 when operating without an assured safe landing capability in the take-off, the take-off phase boundary is defined as:

• 50ft.

• Achieving VY or No later than 200ft Above the take-off surface.

• 200ft.

• 35 ft.

When is it permissible to operate a PC3 helicopter in a hostile environment?

• During take-off and landing by day and by night with the appropriate risk assessment.

• During take-off and Landing by day outside a Congested area with approval from the competent Authority.

• During take-off and landing by day and by night outside a congested area with approval of the competent authority.

• During take-off and landing for all helicopters operating in PC3 in a congested area, with approval from the competent authority.

Indicate the correct statement regarding the take-off and landing requirements of a helicopter operation in PC3 at an aerodrome or operating site located outside a congested hostile environment.

• The maximum take-off and landing mass shall be the higher of the MCTOM/MCLM or the maximum mass for hover IGE.

• As long as an operational approval from the competent authority is held, the take-off and landing phase can be conducted out of sight of the surface.

• A take-off or landing is allowed at night, and by day so long as visibility is greater than 800 m.

• After approval by the Competent Authority, a take-off or landing WITHOUT an assured Safe forced landing Capability may be allowed.

With reference to CAP 758 figure 2.21 find the maximum cruise and VNE at the MAUM given: PA 2000 ft OAT +28°C

• Max cruise 82 KIAS: VNE 97 KIAS.

• Max cruise 95 kts: VNE 97 kts.

If, for a Performance Class 3 helicopter, a Hover In Ground Effect (HIGE) is unlikely to be established due to excessive mass, what maximum take-off mass is allowed?

• The mass that will allow for a vertical climb without hovering.

• The mass Required for a Hover Out of Ground Effect (HOGE).

• The maximum take-off mass.

• The regulated maximum take-off mass.

Which statement regarding the en-route phase for Performance Class 3 is correct?

• Must be able to fly at 1000 ft with a minimum ROC of 150 fpm.

• Must be able to fly at 1000 ft within sight of the surface with a minimum ROC of 50 fpm.

• Must be able to fly at 1000 ft with a minimum ROC of 50 fpm and clear all obstacles by 50 ft.

• With all engines Operating at MCP the Helicopter must be able to fly above the minimum Flight altitude and in the event of an engine failure be able to perform a safe forced landing.
