Performance calculation
Hello Gentlemans))
Please share with your experience.
As usual flight crew calculate the T.O. performance before receiving Load Sheet using Preliminary Data (OFP).
Once receiving the Load Sheet, we have new Mass Data which forced us to update T.O. performance accordantly .
In almost all of routine cases we have lower Mass Data once receiving the Load Sheet, then we had on Preliminary Data (OFP).
Can we suspend recalculation concerning no significant changes to lower Mass (example up to 2 tons)?
The similar question to changes of later ATC Clearance for Intersection T.O. It Might be possible to calculate the T.O. performance for shortage distance(conservative intersection) in advance?
And last question the method of Landing Performance calculation. What is the latest time to recalculate the Landing Distance?
One of mentioned time A&Q EASA GRF 10-15 minutes before the landing. Otherwise perform GA or Holding to have the time.
I can see all of mentioned questioned individual position of each operators. However, very ask to share with your opinions and experience if applicable.
The meaning of my question to save valuable time on time critical stages.
Thanks in advance with your possible comments.
