Density Altitude Descent Threshold 
Flying Magazine

This one is for an unstable approach due to an excessive descent rate (1,232 ft/min). degree glideslope, high density altitude, and an approach speed of 150 knots, all of which put our nominal descent rate very close to the book maximum of 1,000 ft/min. Before FlightPulse, I probably wouldn’t have remembered it.

The calculated density altitude was 4,790 feet. Probable cause(s): The pilot’s failure to maintain clearance from trees after takeoff, during high density altitude weather conditions. The pilot was distracted, and flew too low, striking several approach lights short of the runway threshold.

Temperature An increase in temperature will increase the density altitude. A high density altitude decreases the performance of the engine and the wing. Your aircraft will fly at a faster true airspeed at higher density altitudes. Power controls the rate of descent, and pitch controls airspeed.
