Hi,
Just wanted to share some info.
I recently flew a few short real life flights (passenger) with Scandinavian. ENGM-ENBR and ENGM-ENVA.
I noticed a marked difference in flight behaviour during takeoff, with acceleration at 1500, not decel. Also very high power in TO (maybe) and CLB (for sure). I decided to ask a pilot, and it turns out fuel is now so expensive that the first priority is to get high up FAST. This will potentially add engine maintenance cost, but it is still judged to be a smaller expence than the fuel.
I did not get to ask particulary about derate, but I am quite sure there is no derate at CLB. Maybe TO-1.
The cost index for Scandinavian 737 is now 5.
Hope this is of interest.
Regards,
Andy
