I was an Army Huey pilot from 80-85. I don’t remember details but we had minimum requirements of about 10-12 hours a month. We usually got more that that but there was a lot of variation. If the unit we supported was in the field we flew more. We had instrument hour requirements but nothing like a required
number of take offs or landings
That’d be one flight nearly every workday. That’d be a tough pace to maintain, much less exceed long term. It’s darn tiring work. Especially in peacetime, not actual combat, after awhile you may be building more complacency and fatigue than you are sharpening the edge to a fine hone.
One obvious answer is test flights don’t involve paying money to the defense contractors unless a problem is found… Oil companies do get paid.
