Ops. Reg. Section 8-9

What navigation lights are required to be fitted to a Singapore aircraft?

• Red (Left wing), Green (Right wing) and White (Tail)

• Green (Left wing), Red (Right wing) and White (Tail)

• Green (left wing), Red (right wing), white (tail) and a flashing red fitted to the top and bottom of the fuselage at the mid-section of the fuselage

• Red (left wing), green (right wing), white (tail) and a flashing white fitted to the top and bottom at the mid-section of the fuselage

The lights that aircraft must be equipped with based on Annex 6 (Ops 1.5)

• A red light on the left wing, green light on the right wing, white light on the tail and an alternating red light on the top and bottom of the aircraft mid position

• a white light on the left wing, white on the right wing, tail red light and an alternating green light on top and bottom of the aircraft mid position

• a green light on the left wing, red on the right wing, tail white light and an alternating red light on top and bottom of the aircraft mid position

• a white light on the left wing, red on the right wing, tail green light and an alternating red light on top and bottom of the aircraft mid position

For an a/c flying at 10,000ft in SG at night, apart from steady white, green, red lights, which other lights are required?

• Alternate flashing white & red lights in all directions

• Flashing White lights 70deg dead astern

• Flashing Red lights 140deg dead astern

• An anti-collision light + flashing white light in all directions

Other than white nav lights, what navigation lights are required to be fitted to a Singapore aircraft?

• Red (port), Green (starboard) both 110°

• Green (port), Red (starboard) both 110degree

• Red (port), Green (starboard) both 140degree

• Green (port), Red (starboard) both 140degree

Which of the following conditions define rime?

• A deposit of ice having a crystalline appearance, formed by sublimation.

• A precipitation of light rain, slightly above freezing point, which freezes upon contact with cold-soaked surfaces and objects

• A deposit of ice grains, produced by freezing of super-cooled fog or cloud droplets on objects at temperatures below or slightly above freezing

• A precipitation of ice crystals, which melt upon contact with the aircraft’s surface.

Which statement is correct?

• Rime ice will build up and conform to the shape of the aerofoil

• Hoar frost can occur on the ground and in flight, will affect the lift, drag, thrust, and weight

• Clear ice will only occur in flight and not a cause for concern

• Ice will form more on the inner wing than the outer wing

What is the definition of rain?

• Liquid precipitation, in the form of drops of more than 0.5 mm in diameter or smaller drops which, in contrast to drizzle, are more widely separated.

• Liquid precipitation, in the form of drops of less than 0.5 mm in diameter or bigger drops which, in contrast to drizzle, are more widely separated.

Freezing rain is defined as

• rain in the form of supercooled water droplets which freezes in contact with any surface

• rain in the form of water drops which freezes when in contact with any surface 0 degrees or colder

• precipitation in exclusive form of 0.5mm or 0.2 inches which freezes when in contact with surface 0deg or colder

• precipitation in exclusive form of 0.5mm or 0.2 inches which freezes when in contact with any surface

What is the influence of icing on lift and stall speed? (Ops 8.3.1.2)

• Reduces lift by 30%, increases stall speed

• Reduces lift by 30%, decreases stall speed

• Increases lift by 30%, decreases stall speed

• Increases lift by 30%, increases stall speed

Will two different planes flying in the same icing conditions experience the same icing effects? (Ops 8.3.1.1)

• No, as the icing experienced depends on the design of the aircraft

• Both aircraft will experience the different effects in light and moderate icing conditions but the same effects in severe icing conditions

• Both aircraft will experience the different effects due to rime ice but the same effects due to clear ice
