In the game create a extra Pilot named: Test
Exit the game and open in your Red Ace game directory the file character.ini. Once inside you will see a section which starts with the new pilot name you created (Test). In this section you see a line:
mission = xx
You can set the mission level to 26. Save and exit the character.ini and start the game. Now you will have an extra cheat menu in the goodies menu, were you can enable the cheats.
Fly as high as you want
This cheat will let you fly as high as you want, so high AA guns can't see you to shoot you. No complicated file and directory installations, but its not as easy as just typing it in. Go as high as you can until the barrier pushes you back down. Then go down about 20-50 feet, and then go straight up, and turn off your engine, by putting the throttle all the way down. Then act like a hand glider catching a thermal air pocket, and glide in a circle, while your nose is still pointed up at about a 20-30 degree angle, and glide up until your green dot is no longer on the map, then go as high as you want, but if you go too high, your plane will disappear altogether, just lower your altitude until you see your plane again. There is a certain altitude about 200 feet above the barrier that if you get stuck in it, it will pull you back down past the barrier. Once below the barrier, you can resume control, but while you're stuck in that 200 feet of sky you cannot pull up. Be careful and have fun. This may take a couple of try to master.
