Mr Smokey, are you able to comment on the following?
1. Re Descending at CI 0, does this imply idle power? If not, where does one get the thrust setting?
2. de facto said "Cost index :0 = MAX Range Cruise and Max L/D during descent(239kt on NG)" Is the speed for Max L/D necessarily a CI 0 descent?
3. ReverseFlight says "LRC can be flown with a constant AoA" Does anyone see a requirement for a jet at LRC to have a constant AOA, as fuel burns off (or altitude changes)?
