One of them is the airplane's design maneuvering speed (VA), sometimes confused with the turbulent air penetration speed, which perhaps is better known as design speed for maximum gust intensity (VB).
The meter offers a non-contact infrared depth and penetration speed sensor combined with simultaneous penetration resistance and temperature measurements.
Features include lobed heads to reduce friction and maximize penetration speed, a heat treated alloy steel barrel for exceptional hardness and wear resistance, and a nitrated steel piston with built-in lubrication to minimize wear and resistance.
Hole Hammers feature lobed heads to reduce friction and maximize penetration speed.
Of course, we need to set power to what little is necessary to maintain at or below our targeted turbulence penetration speed, VA, Vo, or V-whatever-the-manufacturer-recommends, corrected for weight, in level flight.
All McLaughlin piercing tools feature lobed heads to reduce friction and maximize penetration speed, a heat treated alloy steel barrel for exceptional hardness and wear resistance, and a nitrated steel piston with built-in lubrication to minimize wear and resistance.
The flight data recorder retrieved from the crashed twin-engine, modern turboprop revealed that while flying in an area of thunderstorm-generated, airframe-shattering turbulence, its airspeed was 60 knots greater than the published turbulence penetration speed, or the speed for maximum gust intensity ([V.
Turbulent air penetration speed is one of the least commonly understood critical airspeeds for three reasons.
It's commonly used as a turbulence penetration speed, as well as a yardstick for all of those "proficiency" maneuvers we're urged to practice and which we need to demonstrate on the Commercial and Flight Instructor practical tests.
