3. From P to Q (where fuel is not available) & return to P maximum pay load is to be off loaded at Q &maximum pay load is to be uplifted from P. the data given is:

Distance P to Q 610 nm

(Weight no fuel) & payload 36500 kg

Max landing weight 52400 kg

Max takeoff weight 63000 kg

Reserve fuel unused 4000 kg

Additional fuel for each flight 500 kg

(R/O circuit landing etc)

Mean fuel consumption 1350 kg / hr

Mean ground speed P to Q 240 k

Mean ground speed Q to P 280 k

Find

5. An ac is to fly from A to BMax T/O weight 82000 lbs

Max weight without fuel & pay load 50000 lbs

Fuel requirements 64000 lbs

a. For flight A to B 16000 lbsb. Reserve fuel 8000 lbs

If the aircraft lands at B after having consumed 500 lbs of reserve fuel what is the maximum pay

load that can be carried

6. In aircraft to fly A to BMax permissible takeoff weight 82000 lbs

Max weight without fuel and payload 50000 lbs

Max permissible landing weight 69000 lbs

Fuel required

a. For flight from A to B 16000 lbsb. Reserve 3000 lbs

What is the max payload that can be carried? Is it possible to carry additional reserve fuel without

affecting the pay load?

7. A flight is to be made from M to N and return to M carrying max. pay load in each direction. Fuel isnot available at N

Given :
