Edited the above to indicate so. Thanks.
BTW, I'd like to ask: The Perf.Book provides minimum V2 speed sto observe Vmu/Vmca values based on pressure altitude(and weight). For a constant QFE, higher OAT means higer p.a. The higher the p.a. the higher the V2 limitaion expressed in kt IAS. If I used an actual higher temp to calculate V2, above the Vmu/Vmca limitation, and departed in colder air:
- The actual Vmu/Vmca limitation would be less so flying above the original limit would do no harm;
- If the original V2 value would be a constraining factor, I may be able to accept higher TOW once I recalculate to observe Vmu/Vmca value that corresponds to the actual OAT. (Wheater this is the case with a specific software tool is probably very hard to tell)
Correct?
Number two: FCOM also provides "Minimum Contol" values for V1,R,2. A different table, only pressure altitude (no weight). These are significantly lower and decrease with pressure altitude. What are they and why they lower with increasing p.a.
See, something has gone seriously wrong with my aerodynamics training. And memory perhaps.
thanks, FD (the un-real)
