You can get a 1900 or Bandit into dirt strips, depends on the length. You can get all sorts into dirt strips, we've operated jet airliners off dirt stripsin the past. Check length & load, as mentioned before.
ATC over the Libyan desert once you've left Tripoli approach 120.9 for Tripoli Control or Cairo Control HF 11300Mhz the comms are difficult but not impossible. Hate to try and get a Mayday in though. In the desert the traffic is the VFR stuff for the oil fields, a couple of Porters and a couple of Twotters. They are mostly early birds and get done by the afternoon by which time it gets a bit bumpy at low level. Theres a couple of Dash-8s doing the rounds during the day and an F28 too. Theres IFR traffic North South at higher levels which you could possibly raise on 126.9, the IATA frequency, aircraft are obliged to give position reports at every waypoint. In central africa you have the onerous Brazzaville control on HF... Your chances in Africa of raising help outside of terminal zones via radio are difficult on HF but not impossible, but you would probably be able to raise another aircraft on 126.9 VHF, there are a surprising number floating around, high and low-level.
Theres a lot of terminal areas around too, they operate on VHF- best to get a Jepp Hi-Lo chart and you'll see who you will be able to talk to along your route. Remember VHF range in nm is 1.25 times the square root of your height in feet. After this distance from your terminal, you're on HF. And when your'e on the ground, your height in feet is about six
the biggest danger in some places is actally having them find you
