The 190 was a very odd airplane when it came to pitch trim. For any speed over 260mph it required only a single trim position, variations in speed alone wouldn't change trim requirement. Trim adjustment would be required for fuel burn, tho. As for ground adjustable trim tabs, the factory had its default setting which could be tossed right out by the pilot. All he'd have to do is tell the mechanic that the left (or right) wing was a little (or a lot) low and to adjust it. Too bad we can't make fixed trim adjustments before takeoff, eh?
