Hey Darren,
I'm sure the FAA would totally agree with you on that, especially during an interview with them after spreading some skids with a dry tank.
They would agree...Like I said, I would not recommend it, but technically legal.
Oh and I'm an offshore guy, haven't flight instructed in quite some time.
Good for you. I remember a few years ago when you were a student still. Glad you made it and did not get stuck in the hole like many others around your time.
condescending tone
Was not meant to be condescending.... We need a "sarcastic" font. But still, in the utility world, it is somewhat normal to run the aircraft on "less than perfect world" fuel amounts occasionally to complete a task.
