TOPER - Takeoff Performance Calculator (free)
Welcome to the world of more realistic flight simulation!
Takeoff Performance Calculator now brings you one step closer to real life aircraft operations. With an extensive database on Boeing 777-200LR performance, TOPER allows you to accurately calculate the highest safe assumed temperature for a reduced power take-off and the appropriate take-off speeds. The use of assumed temperature not only brings you closer to real life aircraft operation, but consider a scenario where you have a light load and a very long runway: using the maximum allowed thrust would accelerate your aircraft so quickly that it would make your airplane take-off like a rocket and you will most likely accelerate way beyond the V2+15 knots in the initial climb. Reduced thrust and reduced rate of acceleration also results in more time for the flight crew to scan the instruments before reaching V1.
Now you can finally use that "TAKEOFF REF" page on your 777 CDU like a pro!
