This question is related to fuel consumption for commercial aircraft. In several books I found that the fuel consumption for a B737-500 (which I take as example) is of 2700 l/h at cruising altitude and at normal cruising speed (908 km/h). I will call this value FCCA. I would like to know the typical values for the following parameters : - Fuel consuption from starting of the engines until reaching of the cruising altitude. This assumes a plane at MTOW, departure 10 minutes after having started the engines, a constant *typical* climbing rate. The value can be in liters or US gallons or l/h or gal/h. This value will be called FCTO. - What time would it take to reach cruising altitude with these parameters. - Fuel consumption from the moment where the aircraft leaves the cruising altitude until it touches ground. This assumes again a constant descend rate, MLW, no reversing of engines and shutdown of the engines 5 minutes after touching ground. This value will be called FCGR. - Can a relationship be made between FCCA, FCTO and FCGR for the B737-500. - Can this be generalized to any aircraft?
