Now that I have completed the assembly of my sounds for all aircraft and vehicles there are quite a few areas I would like to have expanded. One is the fleet guns. Currently it uses explode1.wav, which you can make sound like the 15" guns, or the 5" guns, but in the end they have the same sound. Two would be the engine startup sounds, which I believe are shortened so that users can get right into combat. That means you miss out on a lot of quality sound though. Three would be the landing gear, which has been shortened to just three seconds in a lot of cases, probably for the same reason as engine startups. But it doesn't make any sense why something like the Lancaster has only three seconds to pull its gear up, while some fighters and other bombers have eight seconds (which in some cases is still not enough in reality).
Finally, you come to the gun sounds. In some cases aircraft have various gun packages, but sound packages are limited to using the one M2.wav sound for external sounds (what Pand is describing). So, if you use a 8x.303 package for M2 and the plane is actually using 20mm, then you are in for a surprise if he hits you. Also, some of the Japanese planes have two gun packages even for the plane choices AH uses only one gun package for. The sound creator has the option of choosing Navy, or Army guns, but that choice cannot be made by the pilot because the sounds are limited.
There are lesser issues, like fuel tanks and bomb releases using the same sound. Like Pand I am hoping the change to a new sound engine will address these shortcomings. And I'm sure there are more that I just didn't think of while composing this reply (like dive brakes that just don't have a sound, and so on).
