Certification and Statistics

Question 1

Performance Data produced from pre-production aircraft known as

Answer 1

measured performance

Question 2

Estimated fleet average performance is called … and is used as …

Answer 2

gross performance

a good reference datum for performance calculations

(but does not provide an adequate safety margin for public transport ops as, by definition, half of the fleet will not attain gross performance standards (gross is average))

Question 3

gross performance reduced by an amount that depends on the parameter considered is called …

Answer 3

net performance

Net and gross performance will be very close together for an event that is considered very unlikely (engine failure on take-off) but net performance will be much reduced for a very likely event (a climb conducted without an engine failure) and there will be a much larger margin between gross and net performance
