We had a memo in our airline reminding us to use the correct assumed temp reduction for every take off and the savings quoted were staggering.
Thanks, I'm happy to accept your word (rather than the motherhood statements such as "flex saves money" hitherto offered). If running the engines for a minute or so at the upper end if their performence capability does have such a dramatic affect on their life, then so be it. I wondered if/how many here actually had access to any numbers, and were just doing it because they were told to.
TBALYX et al, well said. (spoken as someone who has experienced/been the victim of the preferred ME management style).
