That exactly is the crux. You're unhappy to sign up for 50% but happy to sign for 20.
150 pilots and 160 different figures. But as I suspect you quite happily fly your a/c with 15.5% pitch along with the others, go on and sign up for 50 just to bring the message across and force some reaction from the company. At least then we'll know where we stand rather sooner than later. And that's one big part of the exercise as I see it. If management still don't give a toss, this is their chance to show it to us.
