DG-IV Hull Overheating on Re-entry?

[Deezlink]

Hey,

I've known about this game for about 2 years, and I didn't really understand it a year ago. However, I am replaying it, and I'm starting to get how to take off and how to move around while taking off. The only thing I need to work on is landing, and whenever I try to do it (I use auto pilot) it says the hull is overheating. I'm freaking out by now, as I have no idea how to stop this. :x So I burn up and crash. D;

Any help? I just started high school, but I love astronomy to death, and I would like to have some tips.

Your hull is overheating because your entry is too steep.
Above 1 degree is too steep. And if you are fully loaded with fuel it will heat even more.

When you fly very fast through the atmosphere, friction causes heat. The DGIV modells this heating pretty accurately, so you need to pay attention for it.

You can avoid the biggest problems by making sure your reentry angle (see the correct display on the DGIV) is more shallow than -1.25°. Next, you need to control your glide angle correctly. Use the autopilot functions of the DGIV for that. When you start to raise again because of the lift, use autopilot bank to fly S-turns - when heating increases, lower your descend speed, you have been flying too fast to low.

Well, I finally found you guys after six-months and the M6 forums going ga-ga. It's good to be Orbiting again!

This post made me fire up the simulator again for the first time in ages - I've never used the Aerobrake MFD before, and I'd never tried to re-enter with the DG IV before either. You'll all be pleased to know that the first attempt with both resulted in a spot on landing at Cape Canaveral.

OK, so the hull temperature hit 2200 degrees. OK, so we pulled 10.7 G's there at one stage and everyone passed out. OK, so I actually flew over the Cape because I was landing at night and I couldn't see anything and when the VOR said I was 22km away from it I didn't realize it meant straight up. And, OK, after doing a 180 degree turn I had to goose the engines for the last 2 or 3 km's to reach the runway- it's not bad for a first attempt after a long break!

I guess all that time flying FS 2004 paid off behind the stick. See you up there.

If you start your deorbit from a very low orbit, you may achieve a colder entry.
If you dump some fuel it may also be colder.
Entry caused me lots of headaches, until Aerobrake MFD appeared.
