Operational Procedures School Exam

Under ICAO regulations what colour should taxi markings be?

Red

White

Yellow

Green

Correct! Wrong!

Taxi markings are yellow, runway markings are runway markings are white.

During approach an aircraft is subject to windshear with an increasing headwind component. Without pilot intervention the aircraft will:

Rate of descent increases, airspeed decreases

Rate of descent decreases, airspeed increases

Rate of descent increases, airspeed increases

All parameters remain the same

Correct! Wrong!

As the wind picks up, more airflow goes over the wing, thus the airspeed increases and the lift increases, resulting in a higher flight path and a slower rate of descent.

What is the squawk code for an aircraft being hijacked or subject to unlawful interference?

7000

7500

7700

7600

Correct! Wrong!

7700 = MAYDAY/emergency code, 7600 = Radio failure code, 7500 = Unlawful interference code, 7000 = VFR conspicuity code

What is the most common fire extinguishing agent used in light aircraft?

Halon

Water

CO2

Dry Powder

Correct! Wrong!

Although halon can be environmentally damaging and poisonous, it can be used for most classes of fire. This makes it the most efficient fire extinguisher for aircraft which make use of multiple materials.

What should be done following an emergency landing which will require an evacuation from the aircraft?

Evacuate passengers and self to a position upwind of the aircraft. If at an aerodrome, clear the runway using the first available taxiway. Turn off all systems.

Evacuate passengers and self to a position upwind of the aircraft after the aircraft comes to a stop. Shut down the engine but ensure that the battery is left on to supply electrical power. Set the parking brake.

Turn off all systems. Evacuate passengers and self to a position upwind of the aircraft after the aircraft comes to a stop.

If at an aerodrome, clear the runway using the first available taxi way. Shut the engine down but ensure that the battery is left on to supply electrical power. Set the parking brake.

Correct! Wrong!

After an emergency landing all people on board should vacate an aircraft upwind of the aircraft, so no debris, smoke or fire will affect them.

The following definition defines what? “The length of the takeoff run available plus the length of the clearway if provided”.

Takeoff run available (TORA)

Takeoff distance available (TODA)

Accelerate stop distance available (ASDA)

The runway length

Correct! Wrong!

The TODA is the length of the TORA (Runway length) + the clearway (height of first significant obstruction).

What is the best course of action after an engine failure over water in a single-engine aeroplane?

Set the speed for maximum range and plan to land parallel to the swell into wind if possible, then make a distress call, squawk 7500 and prepare for ditching

Make a distress call, squawk 7600 and head for land whilst attempting to restart the engine

Make a distress call and squawk 7700. Then if out of range of land head towards any shipping. Just before touchdown position the aircraft parallel to the swell rather than directly into wind

Set speed for maximum endurance and plan to land parallel to the swell and into wind if possible, then make a distress call, squawk 7500 and prepare for ditching

Correct! Wrong!

7700 = MAYDAY/emergency code, 7600 = Radio failure code, 7500 = Unlawful interference code. An engine failure should always be classes as an emergency. In case of ditching the aircraft should be landed parallel/along the swells if the swells are large to avoid tipping over.

What is the most common cause of carburettor fires when an aircraft engine is started?

Over-priming prior to engine start

Excess fuel in the float chamber

Accelerator pump failure

Butterfly valve seized

Correct! Wrong!

In case of engine fire on start up the main cause of fire is excess fuel in the carburettor. This excess fuel is cause by over priming before engine start.

Which statement is correct regarding light signals given to an aircraft on the ground?

Flashing red means stop

Flashing green is clearance to operate on the manoeuvring area

Steady red means move clear of the landing area

Steady green is clearance to cross the runway

Correct! Wrong!

A flashing green light means “cleared to taxi on the manoeuvring area”. A flashing red light means “move clear of the landing area”. A steady red light means “stop”. A steady green light means “cleared to take off”.

Wake Turbulence:

Only occurs when an aircraft is close to the ground

Commences when the main landing gear of a departing aircraft leaves the runway

Is produced when a helicopter hovers, or an aeroplane creates lift

Is not a helicopter phenomenon

Correct! Wrong!

Wake turbulence occurs once any aircraft or helicopter produces lift. The magnitude of wake turbulence is greatest when an aircraft is flying at slow speed and high angles of attack with flaps retracted.

Which of the following extinguishers is not suitable for aircraft?

Halon

Foam

Powder

Water

Correct! Wrong!

Water is not suitable as a fire extinguisher for all classes of fire, thus will not extinguish all possible fires in an aircraft.

Which of the following best describes wind shear?

A slow increase of the wind speed in altitudes above 13000 ft

A meteorological downslope wind phenomenon in the alps

A vertical or horizontal change of wind speed and wind direction

A wind speed change of more than 15 kt

Correct! Wrong!

Windshear is considered to be a sudden change in velocity and/or direction
