Oh, it’s fine, I promise. Engine, avionics, maintenance and structural requirements are excellent and written to great standards. I am not blowing smoke on this; tech writing standards for the parts related to keeping planes from falling out of the sky are stellar. Wanna learn tech writing? Learn from a retired airlines maintenance writer, or better yet, the trainer for one of those teams.
The problem is ground crew, customer service, in-airport ops? Those are where the engine, avionics, maintenance and structural writers learn before being promoted. With much higher wash-out rates. So… yeah.
