Which device is used to measure the airspeed of an aircraft in flight?

Altimeter
Pitot tube
Wind gauge
Potentiometer

Show Answers Only

`B`

Show Worked Solution

→ Pitot tubes measure airspeed by comparing static and dynamic pressure, therefore `B` is correct.

→ Altimeters measure altitude, wind gauges measure wind and potentiometers are a type of resistor.

Why is the routine testing of engineering components important during service? (2 marks)

--- 4 WORK AREA LINES (style=lined) ---

Show Answers Only

→ Aircraft jet engines, diesel trucks, structural beams and a myriad of other engineering components are subject to heavy loads, polluted and corrosive environments, and high operating cycles.

→ It is important to maintain regular routine testing to help guarantee that dangerous conditions or possible faults do not occur.

→ This type of testing has a key role in safeguarding the public as well as increasing the longevity and economic benefit of engineering components.

The terms roll, yaw and pitch describe an aircraft's movements. Each movement is controlled by a specific component of the aircraft.

In which row of the table is each movement correctly matched to the component which controls it?

Show Answers Only

`A`

Show Worked Solution

By Elimination:

→ Elevators control pitch whereas flaps are deployed when aircraft are landing or taking off (eliminate `C` and `D`)

→ To turn the airplane, the pilot uses the ailerons to tilt the wings and roll in the desired direction (eliminate `B`)
