C-5 Galaxy performance documents

[BMBANISTER 0]

I have been flying both the Alphasim and Area 51 C-5 aircraft. Both are really lacking in the documentation of flight performance parameters. Right now I'm specifically looking for  information on optimal altitudes for maintaining normal cruise at different aircraft weights? However, any and all performance data would be greatly appreciated.

 

Thanks in advance

Good luck in finding those. The C-5 is a military aircraft so those doc are most likely classified.

You could measure this yourself.

 

Load up the aircraft with the desired weight.

Start the sim.

Slew the airplane to the first altitude.

Settle into a stable cruise.

Record the fuelflow.

Slew the aircraft to the next altitude.

Etc.

Thanks, that will help until I can find something.

 

The sad truth is I saw a chart years ago when I first purchased the aircraft but didn't save it. I have never been able to find it again.
