Ah, but Percy, the INDICATED airspeed always remains the same for the same event even though the TRUE airspeed changes with density altitude. In other words, if your plane rotates at 60 mph indicated at 30 below zero at the bottom of Death Valley, it will also rotate at 60 mph indicated at 95 degrees at 9,000+ at Leadville, Colorado. (more or less) Therefore, we discounted density altitude as the cause of the problem he reported.
