Rearm & Refuel Menu only operational after switching intercom selector to INT once on hot start

[shagrat]

As per title: if you enter the hot start Huey, the Rearm & Refuel request is only acknowledged once you have switched the intercom from PVT to INT. It does not matter if you switch it back to PVT. After it was on INT ground crew answers in any switch position, with or without open doors.

If you have not switched it to INT prior to opening the Rearm & reuel dialogue, the ground crew won't answer. (no "copy").
 

Tested and reproduced with "Quickstart mission Caucasus "Harbor Tour", but is reproducable with other missions.

- To reproduce just enter a hot start UH1 Huey, open the comm menu (EN keyboard "\", DE keyboard "#") open F8 Ground Crew and F1 Rearm & Refuel, change fuel and/or loadout, click OK - observe no answer 
- Move intercom selector to INT and back to PVT and repeat the above  - ground crew answers with copy

- check again with doors open. - observe the same behaviour. ground crew only answers, after intercom selector was switched to INT at least once.  

Short track attached.
