What is the maximum cruise speed (Vno) for the C-172SP?

The maximum cruise speed, indicated as Vno, for the C-172SP is indeed 129 KIAS (Knots Indicated Airspeed). This speed represents the maximum speed for normal operations in the aircraft, which is critical for pilots to understand as it informs them of the upper limit for safe flight in turbulence and other operating conditions. Vno is also known as the "green speed" and signifies the transition from the green range of the airspeed indicator to the yellow range, which indicates caution.

Exceeding Vno can result in increased structural loads on the aircraft, especially in turbulent air, which could potentially lead to damage if not managed correctly. Thus, adherence to this speed is essential for maintaining safety and ensuring the structural integrity of the aircraft while in flight.
