(a) Design

(b) Modification

(c) Supplement

(d) Validation of performance data

I have been asked this question in class test.

This intriguing question comes from Fixed-Wing Aircraft in portion Fixed-Wing Aircraft Performance of Aircraft Performance

Answer 1

The correct answer is (d) Validation of performance data

For explanation I would say: Performance estimation is applied in fields of design of a new type of aircraft, modification of an existing aircraft type in respect to design changes affecting its aerodynamic characteristics and to supplement or extend the full-scale measured performance of an aircraft type for conditions outside those already established.
