Ultra-high climb rates


#1

Saw something surprising on FlightAware… the normal scheduled FedEx flight from OKC to TUL managed to reach cruise altitude (15,000 ft) in three minutes. And this was reached while still within Oklahoma City limits, about 12 nm east of OKC.

Paging backwards through several previous flights, it looks like this is common for FedEx’s short A300 routes, including on some of the departures leaving Memphis… 4000-5000 fpm climb. I wonder if the planes are empty or bulked out (high volume, low weight) and if they’re using derated thrust even with these climbs.

Do any of you see steep climb profiles on some of the flights departing your areas (not counting KSNA)?
