Title: Re: Questions for ex or present real buff pilots

Greetings, I welcome your commitment with the B-52 :) But, first of all, optimations in the Flight Dynamics are very difficult to change because the core of the FD are in the *.air file. For me, I have taken the changes here in the forum and found a compromise between the mod and the Original. The problem is the correct (max) Speed and AOA while curising. If you use the FD-Mod found here as is, the speed is too low and the AOA too high. Takeoff and Landing with this Mod is ok, but I don't like the high AOA and low (unrealistic) speed. If you would try my settings, here are my settings in the aircraft.cfg: Code (][WEIGHT_AND_BALANCE): max_gross_weight = 488000 empty_weight = 183535
reference_datum_position = 0, 0, 0 // (feet) distance from FlightSim Reference position: (1/4 chord, centerline, waterline) empty_weight_CG_position = -7, 0, 0 // (feet) longitudinal, lateral, vertical distance from specified datum
max_number_of_stations = 50
station_load.0 = 168.0, 64.5, -2.0, 8.0 //Weight (lbs), longitudinal, lateral, vertical positions from datum (feet) station_load.1 = 170.0, 64.5, 2.0, 8.0 //Weight (lbs), longitudinal, lateral, vertical positions from datum (feet) //station_load.2 = 354.0, 0, 0.0, 0.0 //Weight (lbs), longitudinal, lateral, vertical positions from datum (feet) station_load.2 = 354.0, 60.5, 0.0, 8.0 //Weight (lbs), longitudinal, lateral, vertical positions from datum (feet) station_load.3 = 0.0, 0.0, 0.0, 0.0 //Weight (lbs), longitudinal, lateral, vertical positions from datum (feet)

As you see, this is not the whole aircraft.cfg, you have to copy and paste the sections in question. I also modified the Flaps: Now there are only 2 Positions: 50 % and Full. The sections between are not needed for TO and Landing. This saves time and nerves ;) And your answer for your 2. question is also in my cfg as above. I think this is the correct amount of fuel as you can see at, eg. wikipedia. I hope this helps, I know the FD are not 100 % accurate, but for me it is ok and it is better than the original.
