This reminds me of a conversation that I once had whilst working in the BDN P&HQ office for a certain frontline jet. We routinely got stupidly narrow clearances from the manufacturer (admittedly usually for ferry configurations) - say 0/2½g, which annoyed us, and annoyed the aircrew even more.
My boss came out of his office one day, and stormed up to my desk.
"Genghis, you fly microlights don't you?"
"Yes boss"
"What's the minimum flight envelope?"
"+4/-2g boss"
"Can you prove that?"
"Yep, I've got a copy of the airworthiness standard here on the shelf"
"Great, give it to me. I'm faxing a copy to (you'll have to guess the company) and telling them that for a NATO frontline fighter we are no longer accepting more restrictive g limits than a bloody microlight"
