Regards flying an engine "squared", it can very well be done, as Pilot602 said, if kept within parameters. Remember that radial-engined planes, such as those flying with R-2800s or R-3350s, regularly run 57" MP with 2800 (or so) RPM on takeoff. That's quite a difference in "square", but within that engine's limitations. So the point is, know the engine you're working with.

Reminds me of the thread on pax telling Doug about "landing the 1900 with the mixure lean!!!"

About a year ago, an F-16 was on takeoff roll at TUS, when over the tower frequency, a PPL doing his engine runup at the midfield of 11L, called tower that the fighter-jet on takeoff roll had a major engine fire. Tower advised the F-16, which aborted it's takeoff and dropped it's hook for a long-field arrestment, fouling the runway for about 20 minutes while they sorted the situation. The PPL had merely seen the afterburner flame from the engine at max AB, and thought the engine was on fire. [img]/ubbthreads/images/graemlins/rolleyes.gif[/img]
