Thank you I am aware of the use of 1st priciple data in current performance calculation tools, espicially Embraer which offers an AFM or FP option. However my question is what is the difference?
I assume the AFM data has a safety margin factored into the 1st principle data to allow for differing reaction times from line pilots compared to test pilots. Is this correct and if it is what are the safety margins? There must be a written definative somewhere, can you point me to it please?
