I have a 747-200/300 in my hangar that I enjoy flying from time to time. I just reinstalled it and remembered one of the reasons why I had quit flying it.The T/O peformance seems quite realistic - very slow acceleration as the engines spool up and start to overcome all that mass/inertia giving a realistic take off accleration to Vr. But the landing is more like a Twin Otter. It touches down and within a few hundred feet it comes to a stop. I have tried landing without using autobrake and even without using reverse thrust and it doesn't make any discernible distance. Is there a way I can adjust this? I have the AirEd utility so can adjust the AIR file and am comfortable playing with the values in the aircaft.cfg file but am not sure where to start.ThanksIan

Sorry I can't give details, been years since I tweaked brakes, but I do remember: 1) braking strength can be altered in either aircraft.cfg or air file and 2) braking force/slope etc can also be adjusted in fsuipc registered.

Tks Mark - I will certainly check both files and I do have FSUIPC registered so will take a peek there too! But I'm not entirely sure it is the braking strength - it just seems to come to a grinding halt all by itself. Quite impressive short landing but rather unrealistic! :( If I solve it I'll post back here. Meanwhile, if anyone else has an idea or two - I'd be happy to hear itCheersIan

Are you using pedals for rudder/brakes? If so, the brakes may be on slightly in which case, you should increase the null zone (or check the sensitivity). CH Forum has advice about several instances of this. It might also apply to Saitek and other makes.Colin B

Hi ColinI thought of this last night and so downloaded the latest version of CH Manager and recalibrated my CH Pro rudder pedals. In fact, there was an issue with that and the toe brakes were engaging when I used left rudder so I'm now a step ahead of where I was. Sadly, the other issue is not yet solved - it is definitely a problem with this particular aircraft. But it's a lazy Sunday here so I'm going to do some experimenting. I have found values for both braking and reverse thrust so I will try tweaking them. If I find a solution, I'll post it...Thanks for the responses guys :( Ian

Hi Ian.This is easy enough to adjust in the .cfg file. In the [brakes] section, look for:toe_brakes_scale=Default is 1.0. In my own FDE for the Posky 747-400, I have this set at 0.6; essentially the closer to zero the less effective the brakes, so you can adjust it until you're satisfied with what you get.Hope this helps.;)

Thanks for all the good suggestions guys. I think I found the culprit. Though I had tried landing with autobrakes off, I think the switch was just eye candy and the autobrakes were permanently on and absolutely massive in action. Reverse thrust and spoilers were working normally so I changed the aircraft.cfg file to read Autobrake=0 and the problem has gone away. Roll out is now pretty much what I would expect for a 747 landing with VRef at around 160 kts. No more Twin Otter landing roll. Maybe I should have tried landing it at Meigs prior to making the change, just for the hell of it! :( Problem fixed.CheersIan
