Hi Yurgon!
I'm glad you like the mission. I've been away from DCS for a while but I just updated this file to fix a couple of bugs and started adding tasks that are a little farther away (because who doesn't like flying, right?).
Concerning the radio presets: Yes, the radio presets are there because I fly this mission with my group and we use a comms system that is dependant on the presets - hence the presets.
The simplest way to get out of the presets is to flip the Frequency Selection Dial from PRE to MAN. Then it uses the frequency set and shown. Checking the radios should be part of any veteran pilots check list :)
Concerning the APU not air starting -- The mission does not enforce any failures. Nor are birds enabled, so I can't answer why engine failed and the APU didn't start. Were there any non regulated holes in the plane? ;)
Concerning the PERMIT CRASH RCVR, External Views and G-EFFECTS, I have unchecked all but the F10 map view options (which I believe also affect some external views?) this both because of the group I fly with, but also because a lot of the tasks depend on the pilots having to look for something specific. If it would show on the map it'd take away some of the fun. Same goes for civ traffic, some tasks are to find a specific civ vehicle, now if it was the only one on the road...
That said, if there is any part of this mission you do not like simply open it in the editor and change it. If you do and play online on an open server, please state that a change has been made -- for claritys sake.
