conducted in response to circumstances forcing the aircraft to land.

conducted in an attempt to sustain flight safety.

conducted without power from the engine.

conducted with the flaps retracted.

Which of the following landing areas is most suitable for an off-field landing?

A light brown field with short crops

A meadow without livestock

A field with ripe waving crops

A lake with an undisturbed surface

After a precautionary landing the brakes and wheels are very hot. In which way should the pilot approach them?

From the right or left side

From the front or back side

At an angle of 45°

From the front, right or left side

What needs to be observed in conjunction with overheated brakes?

The affected tyres may burst in axial direction

The affected tyres may burst in radial direction or direction of rotation

The affected brakes need to be cooled down with halon

The wheel fairing shall be taken off to increase the cooldown

In case of an emergency ditching, the life vests have to be inflated...

before disembarking the aircraft.

during disembarking the aircraft.

after disembarking the aircraft.

after disembarking the aircraft at a safe distance of about 10 m.

What are the effects of wet grass on the take-off and landing distance?

Decrease of the take-off distance and increase of the landing distance

Increase of the take-off distance and increase of the landing distance

Increase of the take-off distance and decrease of the landing distance

Decrease of the take-off distance and decrease of the landing distance

Under which circumstances may a runway be considered to be contaminated?

When more than 25 % of the runway surface area within the required length and width being used is covered by water, slush, snow or ice more than 3 mm deep

When more than 50 % of the runway surface area within the required length and width being used is covered by water, slush, snow or ice more than 3 mm deep

When 75 % of the required runway length and width are covered by contaminants such as snow, frost, ice or sand

When more than 50 % of the required runway length and width are covered by contaminants such as snow, frost, ice or sand

What minimum coverage with ice or snow must be given to call a runway "contaminated"?

75 %

50 %

10 %

25 %

Wet snow on a runway can lead to...

increased rolling resistance during take-off.

reduced rolling resistance during take-off.

an increase in lift.

a decrease in lift.

What danger does standing water on the runway pose to aircraft?

Increased rolling resistance during take-off

Decreased rolling resistance during take-off

An increase in lift

A decrease in lift

Which danger exists after a heavy rain shower for a landing aircraft?

Displacement of the tire slip marking

Longer braking distance due to aquaplaning

Decreased braking distance due to aquaplaning

Difficult flare due to glare

Which would be the correct reaction when hydroplaning is suspected upon landing?

If all wheels are in motion, brake moderately. Maintain directional control by aerodynamic means

Apply maximum braking to reduce aircraft speed to less than hydroplaning speed, then continue normal ground roll

Add power and use flaps and spoilers to brake aerodynamically

Cross rudder and aileron controls in order to use the aircraft fuselage to brake aerodynamically

What does the brake coefficient specify?

The proportion between friction force and contact pressing force between two objects

The proportion between Coriolis force and contact pressing force between two objects

The proportion between brake force applied and landing distance

The proportion between brake force applied and landing ground roll

How should a landing on a contaminated runway be conducted if it proves to be inevitable?

Approach with the minimum crosswind component possible, use maximum flaps, touch down firmly with minimum speed, brake carefully

Approach with the minimum crosswind component possible, use minimum flaps, touch down softly with minimum speed, do not apply brakes

Approach with the minimum crosswind component possible, use minimum flaps, touch down softly with positive pitch and minimum speed, do not apply brakes

Approach with the minimum crosswind component possible, use maximum flaps, touch down with negative pitch and minimum speed, brake carefully

Which of the following weather phenomena is most hazardous during approach and landing close to frontal thunderstorms?

Gusts

Falling pressure

Decrease in temperature

Precipitation

Operational Procedures - AC
