We don't have the weight here, but we have the body pitch angle, and the Indicated Airspeed: 82 ktn, 44deg pitch up. When you search for the stall speeds on the net you will find an interesting article on.
#FLIGHTGEAR 737 FULL#
With full flaps, at MTOW (Maximum Takeoff weight) (143000lbs/ 65000kg) Vref 152 knots. Vref is always = stall speed x 1.3! so stall speed would be here around 82 knots. So with full flaps, at lowest possible weight (77000lbs/ 35000kg) Vref is 107 knots IAS. Vspeeds are very, very important! If an aircraft does not rotate at the specified Vr, it has to be reported to the authorities, and the issue has to be examined! And the vspeeds are correctly simulated on the FGFS 737-300. I have tried some weights and speeds- and indeed they all work in the way I would expect. I think they are based on this very good site: It gives you all the Vspeeds at all possible weights! Have you searched for datas on the net? I don't think so- more below! And have you read the help section on Menu -> Help -> Aircraft help? Cunningham the wings etc I have to diasgree. The FGFS wiki gives by the way names of all the authors who has in any way contributed to the model.

In your download it is actually the same fdm like on FGData and on the Download page. Now I stumbled upon this I wanted to try your improved aircraft. I came back to see how FGFS has developed. Good question is where to find proper good data? But I don't know about it at this moments (I'm interested in good 737, so I'm looking for data). I can fly around 110 kts on idle with nose up and do not touch the runway. Original by David Culp have the same unrealistic behavior on landings - too high stability on very high angle of attack and too low drag with full flaps and gear down.

Honza Honzaku Posts: 88 Joined: Sat 5:00 pm Location: Between LKPR and LKVO, Czech Republic But the plane desperately calls for some decent 3D cockpit, systems and working instrumentation on the level of quality of B 777 or even Tu 154 which, first of all, would make it finally flyable. So he probably knew very well what he was doing when he was writing FDM and I am not sure If there is currently anybody else who has enough of information and know-how to significantly improve the FDM. On the other hand I would leave the FDM as it is, at least for the beginning, since the FDM has been made by David Culp, who is one of the developers of JSBSim, has degree in aeronautical engineering and is also real life pilot who has spent many hours on B737. The lack of these points is the biggest issue on this particular plane and makes the flying of it very unpleasant and difficult. In my opinion, I would concentrate the most of the effort in the system developments, avionics and cockpit 3D. It is great to hear someone is improving this legendary classic airliner which is still missing in Flightgear in acceptable quality.
