Q1. Wingtip vortices that cause wake turbulence are generated whenever an aircraft is:
  • A.  Flying above 10,000 ft
  • B.  Producing lift
  • C.  Fitted with retractable undercarriage
  • D.  Using full power
Show answer & explanation
✓ Answer: B. Producing lift
Vortices form because lift creates a pressure difference between the upper and lower wing surfaces, causing air to spill around the wingtip. They exist from the moment the aircraft rotates on takeoff until it touches down on landing, and stop once lift generation stops.
Q2. Which condition is the most reliable indicator that a microburst-induced windshear encounter is in progress on approach?
  • A.  A rapid increase in airspeed followed by a rapid decrease as the aircraft passes through the outflow
  • B.  A steady, gradually increasing headwind throughout the approach
  • C.  A constant crosswind component with no airspeed fluctuation
  • D.  A gentle rise in indicated airspeed that persists to touchdown
Show answer & explanation
✓ Answer: A. A rapid increase in airspeed followed by a rapid decrease as the aircraft passes through the outflow
A microburst produces an increasing headwind (airspeed surge) as the aircraft enters the outflow, followed by a sharp decreasing tailwind (airspeed loss) as it exits, often with a strong downdraught in between. A steady or gently rising airspeed trend does not match this signature and is a normal wind gradient effect, not a microburst.
Q3. An engine fire occurs during the start sequence on the ground, with flames visible from the exhaust area. What is the immediate priority action per standard PPL training?
  • A.  Continue cranking the engine to try to draw the fire into the cylinders
  • B.  Close the throttle, close the mixture to idle cut-off, and continue cranking to try to clear excess fuel
  • C.  Shut down the fuel and electrics immediately and evacuate without further engine handling
  • D.  Apply full throttle to increase airflow and blow out the flames
Show answer & explanation
✓ Answer: B. Close the throttle, close the mixture to idle cut-off, and continue cranking to try to clear excess fuel
For a start-up fire (typically caused by over-priming), the standard drill is to continue motoring the engine with the mixture at idle cut-off, which can draw the fire back into the engine and extinguish it by starving it of fuel and increasing airflow. Immediately abandoning without this step misses the recognised first response. Full throttle is not part of this drill and could worsen the fire.
