Quiz: 6 Questions To See How Much You Know About V-Speeds

Thanks to Bose for making this story possible. Check out the full series here. And if you want to know why we fly with Bose, learn more about their headsets here.

How much do you know about V-Speeds?


  1. 1) As your aircraft's gross weight decreases from fuel burn, your maneuvering speed (Va):

    As gross weight decreases, maneuvering speed also decreases. That's because at a lower weight, you fly at a lower angle-of-attack. And when you fly at a lower AOA, you're further from the critical AOA, as well as stall.

  2. 2) The point where the green and yellow arc meet on your airspeed indicator is:

    Vno is the maximum structural cruising speed. Any speed above Vno should only be flown in smooth air.

  3. 3) Two identical aircraft take off from the exact same point on a runway. The airplanes are the exact same weight, with the same CG position. One climbs at Vx, the other at Vy. Which one will reach 1000' AGL in the least amount of time?

    Vy is the best rate of climb speed, which means the Vy airplane will gain the most altitude in a given amount of time.

  4. 4) You're descending into an airport for landing. What is the fastest speed you can fly with your flaps extended?

    Vfe is the maximum flap extended speed.

  5. 5) What climb speed will give you the most excess force (thrust)?

    Your propellor can generate the most thrust at a slow speed, because it's at a high angle of attack. As your airspeed increases, the propellor's angle of attack decreases, and it can generate less thrust. The largest space between thrust available and thrust required is your Vx speed.

  6. 6) As aircraft weight is increased, stall speed in a landing configuration:

    As weight increases for an aircraft, stall speed (of any kind, Vs, Vso, etc.) also increases. This is why V speeds, like Vso, are calculated at the aircraft's maximum gross weight.
