PPL operational procedures 070: practice questions and syllabus

Operational procedures gather what is out of the ordinary: noise and runway incursions, engine fire or smoke, wind shear, wake turbulence, emergency landings and contaminated runways, following the EASA PPL syllabus. The answers are actions to know before you fly: go around in wind shear, shut off the fuel with the firewall valve, reduce propeller noise, cut the fuel and move away after a forced landing. Our bank has 141 questions on this subject.

5 questions to practise

Taken from the site's English bank and checked one by one. Read the question, choose your answer, then open the explanation. Like every explanation on the site, they may contain errors.

  1. Question 1 · 2 Noise abatement and runway incursions

    To reduce noise, the pilot switches:

    • Afrom full fine pitch to a coarser pitch.
    • Bfrom coarse pitch to a finer pitch.
    • Cfrom a given mixture to full rich.
    • Dfrom full rich to a leaner mixture.
    Show the answer+

    Answer: A. from full fine pitch to a coarser pitch.

    Propeller noise comes mainly from the blade tips, which are the fastest-moving parts. Changing to a coarser pitch makes the propeller turn more slowly: the tip speed, and therefore the noise, decrease.

  2. Question 2 · 3 Fire and smoke

    The control called the 'fire shut-off' allows, in the event of a fire:

    • Ato prevent smoke from filling the cabin.
    • Bto cut off the fuel supply to the engine.
    • Cto trigger the extinguisher protecting the engine.
    • Dto shut down all electrical circuits.
    Show the answer+

    Answer: B. to cut off the fuel supply to the engine.

    The fire shut-off control closes the fuel supply to the engine: it does not extinguish the fire itself, but cuts off what feeds it.

  3. Question 3 · 4 Wind shear and wake turbulence

    A windshear avoidance procedure on approach mainly consists of:

    • Areducing power and continuing the approach.
    • Bperforming an immediate go-around and moving away from the area.
    • Clanding at all costs.
    • Dsignificantly increasing nose-down pitch attitude.
    Show the answer+

    Answer: B. performing an immediate go-around and moving away from the area.

    When facing significant windshear on approach, the recommended procedure is to discontinue the approach with a prompt go-around rather than continuing toward landing.

  4. Question 4 · 4 Wind shear and wake turbulence

    Wake turbulence is all the more dangerous in:

    • Acalm air, behind a light and fast aircraft.
    • Bturbulent air, behind a heavy and slow aircraft.
    • Cturbulent air with strong wind gusts.
    • Dcalm air, behind a heavy and slow aircraft.
    Show the answer+

    Answer: D. calm air, behind a heavy and slow aircraft.

    Wake turbulence is all the stronger when the aircraft generating it is heavy, large and slow: at low speed, it flies at a high angle of attack and stirs up a lot of air. In calm air, the vortices persist and dissipate slowly; wind breaks them up or moves them away.

  5. Question 5 · 5 Emergency landings and contaminated runways

    After a forced landing in open country with no injuries, the crew's immediate priority is:

    • Ato shut off the electrical circuits and fuel, and move away from the aircraft.
    • Bto try to take off again if the terrain allows.
    • Cto photograph the damage for insurance purposes.
    • Dto stay on board while waiting for rescue.
    Show the answer+

    Answer: A. to shut off the electrical circuits and fuel, and move away from the aircraft.

    After a forced landing, the electrical power and fuel system are shut off (fire risk) and then the crew moves away from the aircraft to a safe distance before raising the alarm, rather than staying close to a potentially damaged fuel tank.

How to approach this subject

These are actions: learn them as scenarios. Wind shear on approach: go around at once. Engine fire: shut off the fuel supply with the firewall shut-off valve. Forced landing: switch off electrics and fuel, then move away from the aircraft. Wake turbulence: most dangerous in calm air behind a heavy, slow aircraft. Noise: it comes mostly from the propeller, and a coarser pitch makes it turn more slowly.
