What effect does high density altitude have on aircraft performance?(a) Decrease in climb performance(b) Increase in climb performance(c) Increase in take-off performance(d) Increase in engine performanceThe question was asked during an interview.I'd like to ask this question from Fixed-Wing Aircraft in division Fixed-Wing Aircraft Performance of Aircraft Performance

Answer»

Right ANSWER is (a) Decrease in climb performance

To explain I would say: There will be a decrease in climb performance with INCREASE in high density ALTITUDE. On increase of altitude there would be a decrease in density which RESULTS in decrease in power output of engine and airfoil efficiency, as a result there will be a decrease in climb increase performance.
