Once you determine the drive pulley size you have to install an unloader valve of some sort as the engine will not want to start with pressure in the lines.
At the tank you want a check valve and between that check valve and motor a pressure relief so as to not overload the tank.
For a cheap easy solution a slow leak, LOL, B4 the check valve will bleed off pressure allowing unloaded start up.
(even a leaky fitting can do) and with the large volume of air generated performance would not suffer.
You said aviation, so I suggest even hydraulic relief valves and PRV will do the job if you have some 'odds and sods' in your tool box.
(a also aviation guy and have used lots of odds and sods for air, note hydraulics generally are much higher pressures so safe)
