What propellor plane, other than planes with vertical takeoff capability, has the largest gap in speed between its slowest stall speed and its maximum airspeed? I am looking for a plane with a short take-off but also can go fast if needed or slow and fuel-efficient.

    $\begingroup$ Basically the fastest plane wins that record (since planes eventually land at very moderate speeds). So it will be the SR-71 or the Shuttle, depending on how you define a plane. Also kindly check How do I ask a good question? It's better to ask questions that invite how and why. $\endgroup$ – ymb1 Jan 25 '20 at 5:13
  • $\begingroup$ @Xaddell: Hover over the tag, it says "A heavier-than-air fixed-wing aircraft propelled by one or more engines." The term airplane has nothing to do with the propulsive method, so an SR-71 and a 747 are as much planes as a Cessna. $\endgroup$ – ymb1 Jan 25 '20 at 6:15
  • $\begingroup$ @ymb1 Thank you for correcting that. I will revise the question. $\endgroup$ – Muze Jan 25 '20 at 6:16

    $\begingroup$ @Xaddell: So you're asking what the fastest STOL airplane is? If yes, then I think it's easy to find out. There's also this: Would a two-seat light fixed-wing aircraft with a landing speed of 20 knots and a top speed of 180 knots be technically possible? $\endgroup$ – ymb1 Jan 25 '20 at 6:26
