Hot air to the FAB 320 airbox

[Steve Sampson]

Anyone got a picture showing how they organised the fitting to aim air into the air box door on a 320? There is not much room!

Also, how tight up to the door does it need to be, and is there a need for air to circulate through the muff at all times to prevent overheating?

Thanks

The ram air door does not need to be extremely tight. If it is too tight, it can cause interference and possibly jam.
Yes, air needs to circulate through the muff continuously. If not the muff and/or hose can burn out from over heating.
