Question 31

With all tanks full an aircraft holds 230 litres of fuel. If the Specific Gravity of the fuel is 0.72 what is the approximate weight of the fuel in lbs?

Answer 31

364lbs Use CRP1 or 230 x 0.72 = 165.6kg 165.6 x 2.2 = 364.3lbs

Question 32

How will and uphill slope effect take off and landing

Answer 32

Decrease landing distance | Increase take off distance

Question 33

Calculate the max fuel that can be loaded and what is the centre of gravity Max take off mass 2400lbs

Answer 33

Work how much fuel can be loaded 2400 - all other weight = 300lbs Convert lbs to kg 300 / 2.2 = 136.4 kg Divide by the specific gravity (0.72) to get litres 136 / 0.72 = 189.3 litres

Question 34

Calculate center of gravity postion Total mass = 2400lbs Moment = 49550 Lb ln

Answer 34

Moment / mass =cg 49550 / 2400 = 21.08

Question 35

On landing what is the cg position Departure weight = 2300 Cg on departure = 85.75 Fuel burn = 300lbs (82 inches aft)

Answer 35

Moment on departure =weight x moment 2300x85.75 = 197225 Moment arm of fuel used = fuel burn x moment 300x82 = 24600 Landing moment = departure moment - fuel used moment 197225 - 24600 =172625 Landing weight 2300 - 300 = 2000 Cg position = landing moment / landing weight 173625 / 2000 =86.31
