Exercise 2

Complete the Integrated Flight Plan from the following data:

The aircraft’s estimated cruise weight is 60 000 kg; the ramp weight is 61 500 kg. It is tasked to fly a route where the overall magnetic variation is 15°W. The trip is to be flown at the lowest ICAO IFR optimum pressure altitude for M 0.78. Details are provided in the attached Flight Plan and all the airfields are less than 100 ft above mean sea level. The forecast QNH at the destination, E, is 1029 hPa.

Fuel:
Route:	Allow 5% contingency A to E.
Descent:	Straight in descent with gear down with turbulence forecast.
Diversion:	Use Alternate Planning CAP 697 MJRT1 Figure 4.3.6.
	estimated landing weight 47 000 kg.
Taxi/APU:	Allow 20 min APU and 20 min Taxi.
Air Conditioning:	1% extra to cruise fuel to destination.
Engine and wing anti-ice:	180 kg/h for cruise A to E.
Holding at E:	Compute 45 min holding fuel, straight and level, at an altitude
	of 2000 ft overhead E. (CAP 697 Figure 4.4)
Assume an initial weight of	50 000 kg.

When complete, answer the following:

a.During the descent into E the pilot selected the flaps down 4 minutes before the ILS outer marker. What extra fuel was burnt?

b.How much of the contingency fuel was used if the engine anti-ice was selected during the descent?

c.If the anti-ice, air conditioning and half the taxi/APU fuel have been burnt, what is the estimated landing weight at E?

d.If a LRC flight is planned to operate in the ECON mode what adjustments to fuel and time are needed if the Cost Index is 30?
