Frequently Asked Questions

Q. A-12 Engine RPM doesn't reach 100%?

A. The max operating RPM was 7450 rpm, anything above that required inspection and manufacturer notification - the RPM gauge shows corrected RPM not the percentage.

Q. Using your A-12 I cannot reach Mach 3 or 80,000 feet?

A. You need to follow the guidance in the included PDF manual - the aircraft must be flown within critical parameters to reach high speed and high altitude. Climb must be flown at 450 KEAS in order to reach Mach 3. The 'dipsy-doodle' from 33,000ft + descent to over Mach 1, then slow pitch up must be performed in order to fly a 450 KEAS climb schedule.

Q. My A-12's engines quit above 20,000ft?

A. You've experienced an engine compressor stall on one or both engines, you need to keep your angle of attack shallower or your engines will not be able to get sufficient guided air flow to prevent stalling.

Q. I cannot land the A-12 without stalling?

A. You need to fly the approach with as little fuel as possible. In real life pilots would land with only a few thousand pounds remaining. Use the aircraft's fuel dump and forward transfer switch to lower the touchdown weight and move the remaining fuel forwards.
