One of the default missions bundled with the DCS: Huey module offers an interesting high altitude challenge.
If you’re looking to do the same or a similar flight here are some tips to help you get through in one piece.
In this mission the troops awaiting rescue have setup a homing beacon, so set your radio nav to home on 40.50 and turn down the volume once you confirm that it’s tuned correctly.
You’ll need to climb up to the peak efficiently. To do this maintain about 60 knots which is listed as the best climb speed. It may look like you’re barely moving but looks can be deceiving.
When you’re climbing or landing keep an eye on the rotor RPM, as if you over load the transmission the RPM will fall, and so will the helicopter in a stall.
Landing at high altitude carries extra risks, I would probably recommend approaching lower than I did so you avoid being outside translational lift and ground effect. It’s not uncommon to trigger the low RPM and you can get yourself into a situation where you can’t recover.
Once you’re on the ground and loaded up the flight dynamics are a bit trickier. In fact you may find yourself unable to gain altitude and end up upside down when you attempt to egress. The emergency gov switch will disengage the power limiter for a few seconds, these should be used to try to get translational lift through forward flight. As you can see in the video I managed to bump the skids both times leaving the peaks of Mount Elbrus. Cue fist punches and high fives.
The hardest part of this mission is flying back with the casualties on the first trip. You have a serious time limitation not helped by the fact that I took a longer descent around the ridge-line. I would recommend taking a more direct approach but this will be steeper and more hazardous.
My flying is decidedly average because of the emergency. I sacrificed all passenger comfort for getting the job done before the sun went down!
This mission is packaged as a default mission for the DCS: Huey module available from Eagle Dynamics.

NOTE: You may notice I did not complete the start-up correctly and I also have no idea how to turn on the radar altitude.
