I'll give this a huge +1!
When i first joined the server i was a little confused why aviation is almost non existant here, even though it makes sence, not everyone flying a heli.
Currently aviation is accesible only for PD and MD. This is one of the reasons i became a pilot in the PD division as soon as i could.
The system would have be carefully planned to work, something like heartgg suggested. Almost no record. They would also be regularly checked. Some kind of radio connection would have to exist between pilots. Otherwise it'd be a mess. Someone landing and taking off from the same place. The communication should be encripted or hard to acces so not everyone can go to LSIA, wait for a plane and start.the "hands oop". One suggestion for this would be to make the gates of LSIA lockable. And only people with an aviation license would be able.to unlock them. You would also need to get permission from Staff to hijack a plane (which could create an awesome RP scenario)
As a supporter of aviation, this is something i'd like.to see.
