If you understand every thing it can be done.
Civilian aircraft and military aircraft use different mike systems.
Civilian aircraft uses WW-II type carbon equivalent mikes.
They can be used with most H T. with the proper attenuation.
The best way is to use a separate noise canceling mike with the ham HT.
I use a military mike on my stuff, but have some carbon equivalent stuff
You can match any thing to any thing , but it is a hassle.
Most good commercial noise canceling mikes for aircraft cost more then a
Ham radio you want to put it on.
