Which factor tends to increase density height at a given aerodrome - ANS->Increasing ambient temperature Which is the best airspeed to fly at to clear obstacles after take-off - ANS->Best angle of climb Which of the following would you justify the use of a mayday call: - ANS->You have an engine failure on a training flight Using a fuel of lower grade than that recommended for the particular aero-engines could cause: - ANS- >detonation An aeroplane moves forward in steady straight and level flight because: - ANS->thrust equals drag You have planned a private cross country flight requiring flight time of 2 hours and 45 minutes. Your maintenance release indicates the aircraft is due for inspection at 1290.00 hrs and the progressive total is in Part 3 is 1287 hrs and 45 minutes. What will be your actions? - ANS->Cannot proceed with your flight An aeroplane's fuel must be checked for the presence of water: - ANS->Prior to the first flight of every day and following each refuelling Fuel that appears to be uncoloured or a very pale yellow is: - ANS->AVTUR for turbine engines (i.e. jet or prop-jet engines) To move the CoG rearwards you could: - ANS->shift passengers or baggage aft
