Which is more economical in the long run

[shon7]

Is it more efficient and economical to have a company policy --

1) Where the flex takeoff is used anytime conditions allow using a full length runway

or

2) Is it better to not have such a policy where pilots can accept intersection departures without using a flex takeoff.

Full-rated takeoffs ultimately cost more because of the longterm effects of deterioration in SFC and EGT/ITT margin. The sole driver for flex takeoff is economics (keeping engines healthy longer).

About the only time I can see a voluntary full-rated intersection takeoff making sense is to make up schedule time vs. missing an arrival gate.
