Aileron Horizontal Stabilizer Indicated Airspeed 
Pilot Institute
JULY 11, 2025
Why don’t they use Indicated Airspeed just like the pilots who fly slower aircraft? Key Takeaways Mach number is a dimensionless ratio of true airspeed to local speed of sound. That’s the speed your airspeed indicator shows based on ram air pressure in the pitot tube. Here’s why.

Ailerons are actuated by pushrods that run through the wing struts, reducing aerodynamic drag and giving the responsive ailerons a solid feel. There are gap seals between the elevator and horizontal stabilizer, and the rudder and vertical stabilizer. Handling is delightful. Stalls were true nonevents.

Alongside a nearby highway, some recognizable bits of airplane, the vertical stabilizer and rudder, a horizontal stabilizer and elevator, fell separately to Earth. I did my first aileron roll in an RV-4. The margin beyond VNE in indicated airspeed and the onset of flutter may be less than many pilots would guess.
