So I did a test in the F-14 this afternoon out of PHNL headed south-southwest … Hit Mach 1 at under 10K feet, though I didn’t particularly try to go very fast very low.
I trimmed it out level at a little over 11,000’ and Mach 1.1, 629 kias. At this point, the aircraft still had close to 50% internal fuel and in the dense air, airspeed was increasing very slowly.
I trimmed it out level again (within +/- 300 fpm) at 19,700’ and Mach 1.7, 865 kias.
Finally I put on the autopilot and climbed up to the maximum ceiling. With under 20% internal fuel remaining, I maxed out at an absolute ceiling of 49,970’ and Mach 2.426, 903 knots indicated.
That’s 1,349 knots across the waves, with a true airspeed of 1,362 knots with the quartering headwind.
Not bad for the old girl.
I then turned back toward Hawaii but didn’t trust the fuel remaining, so I “refueled” in flight, to make it home. Came west of Oahu and made a long straight-in east approach. I landed a bit fast, bounced a bit, hit the spoiler to kill the airspeed and set it down … but my spoiler toggle is the same three-way switch that controls my gear. When I went to raise the spoiler, I accidentally retracted the gear and crashed when I recovered from the bounce before I realized what had happed. Oops.
