MOSAIC caps the maximum speed of light-sport category aircraft at what?

250 knots CAS.

  1. 120 knots CAS
  2. 200 knots CAS
  3. 250 knots CAS ✔

Why: MOSAIC removed the old weight limit and set a new top speed: a light-sport category aircraft may have a maximum level-flight speed (VH) of 250 knots CAS. Sport pilots still have their own separate aircraft limits.

Huh, didn't know that: The rule also lets light-sport aircraft use turbine engines and electric motors.
