I had a question come up:
If aircraft A is identical to aircraft B, except that aircraft B weighs 200 kg more. Which of the following statements are true?
The answer I selected was wrong:
Aircraft A would need less power to fly at the same speed as aircraft B
I pictured that with less weight, a reduced angle of attack would result in less drag and hence less power? Would anyone be able to “lighten” me with this?
Thanks for the feedback, it may have just been a typo..
The 4 multiple choices where:
1) Aircraft A would need less power to fly at the same speed as aircraft B
2) Aircraft A would need the same power to fly at the same speed as aircraft B
3) Aircraft B would have poorer climb performance
4) Aircraft B would require a longer runway for landing
