What is the recommended penetration speed for thunderstorms?

The recommended penetration speed for thunderstorms is 180 KIAS. This speed is considered optimal for several reasons. First, it provides a balance between maintaining aircraft control authority and ensuring some margin above stall speed while navigating turbulent air. Thunderstorms are often associated with significant turbulence, and flying at 180 KIAS helps to mitigate the adverse effects of that turbulence, allowing the pilot to maintain better control of the aircraft.

Additionally, this speed is within the operational envelope of the T-6A training aircraft, allowing for effective maneuverability in and around storm conditions while still managing the risks associated with potential updrafts and downdrafts. The selected penetration speed also permits pilots to make swift decisions if the need arises to divert or escape from dangerous weather. Importantly, flying at this speed contributes to safety by reducing the likelihood of encountering excessive structural stress on the airframe during flight through severe weather conditions.
