"An airplane performing one slow revolution around its longitudinal axis is performing one of these..."

This was a clue on Jeopardy today. The contestant responded with, "What is a barrel roll?" which I contend is incorrect. But he earned $2000 for it.

My response would have been: "What is an aileron roll?" Is he correct, am I correct, or are we both correct?


What is an Aileron Roll?

You are correct, but should we really expect that level of precision from the entertainment business or the media?

    $\begingroup$ To be fair, a slow aileron roll executed by a slower, lower performance aircraft will also not be merely a revolution about the aircraft's longitudinal axis since a true aileron roll involves maneuvering to maintain altitude. $\endgroup$ – J Walters Jan 11 '17 at 3:50
  • $\begingroup$ As long the longitudinal axis stays with the aircraft (as every sane pilot will strive for), any roll will be correct since it does not exclude other manouevres. $\endgroup$ – Rob Vermeulen Jan 11 '17 at 18:33
