Questions

Recommended Posts

Ok i have to re-write this because i guess they didn't think the way i put it was ok to post lmao ok well..
first off I see questions happen here all the time for example saw one post where some one asked if it was possible in FSX to stop the plane from crashing from overspeed..
99% of the answers they get was people replying with no help what so ever or not answering their quetions all this Original poster got was posts to make them look good or try and prove they are some Pilot GURU..
doesn't seem to make any one look smart in my opinion specially when they know what the poster is asking and not answering the question, just making some speech about aircraft and try to look smart..

Ok for who ever asks this question here is a simple way and answer to your question and not have to read posts about things you could care less..
Ok first off you need to Edit your Aircraft.CFG file, this is located in your FSX directy under sub folders. in the aircraft folders you will see the modes of aircraft you have just click into that folder of your aircraft and edit the "Aircraft.cfg" File this will have stuff in it you can tweek..

so here is en example for a steam fsx and where it all is..

C:\Program Files (x86)\Steam\steamapps\common\FSX\SimObjects\Airplanes

then you choose the folder of your aircraft..

then edit the cfg file..

 

this is an example of the 737-800

inside the cfg file you will see

 

[Reference Speeds]
flaps_up_stall_speed    = 142.0                 //Knots True (KTAS)
full_flaps_stall_speed  = 113.0                 //Knots True (KTAS)
cruise_speed            = 477.0                 //Knots True (KTAS)
max_mach                = 0.82
max_indicated_speed     = 340                   //Red line (KIAS)

 

 

 

Where it says Max Indicated speed change that value to a higher speed, for example if you want to go faster then 340 knots and go 400 knots set it to 440 knots.. make sure you change the Mach as wel

where it says Max_Mach =0.82 that is for speed 340 knots if you want to change the knots to 400 knots then you set the mach to  mach 0.51

you can run a knots to mach calculator from the net just google it..

so that is easy as that, make sure if you tinker around the cfg file you don't mess things up back up your "aircraft.cfg" file before you edit it..

 

making changes to it can cause problems or change the way your aircraft flys and takes off or lands as well..

for example if you wanted to increase the fuel capacity to a higher number and have more fuel, then if you do that you could cause the aircraft not be able to take off because of the extra weight, or making landings have to be done at a higher speed because more weight causes less lift..

if you increase the fuel capacity, i would say you should increase the power of the engines and thrust to help you maintain enough power to lift off the runway and fly correctly..
but then again your changing the design of the aircraft and dong this you need higher speeds for lift and cruising speed as well..
but you can have fun with it and do crazy things.. i once edited a 737 to be able to go the speed of sound and go further then it was designed to by increasing the capacity of the fuel tanks 🙂

i also created one that flys at a slower speed and stalls at 60 knots lol and so making landings unrealistic like a piper pa28..

any way here is the answer to your questions regarding that..
