lol that’s how I feel sometimes.
I remind myself that the previous generation said the same thing about me. I recently read an account of Guy Gibson trying to light a cigarette and maintain 100ft AMSL at night over the ocean while leading a formation flat out. In the end he got his second pilot to light it as the nose kept on dipping each time he tried.
F280 is a lot easier than even F330.
I made the mistake of staying up at FL370 for over an hour when fuel wasn’t an issue. I’d definitely drop down a bit if it happened again just to reduce workload. It wasn’t a problem as such but neither of us could trim it to a nice stable hands off state.
