In the current version, the AV-30 has a highly customizable attitude indicator display that faithfully mimics a traditional spinning gyro, but overlaid with data such as indicated airspeed, altitude, baro, AoA, OAT and GPS track data.
Wind shear from the tail of the airplane is a performance-robbing event, with a sudden and short-term reduction of indicated airspeed. The Bonanza's usual 80- to 90-knot indicated airspeed just after liftoff would have been momentarily reduced to 21 to 31 knots--well below stall speed.
The aircraft "began a descent from 5,500 feet about 34 miles west of MVY [Martha's Vineyard], The speed during the descent was calculated to be about 160 knots indicated airspeed (KIAS), and the rate of descent was calculated to have varied between 400 and 800 feet per minute (fpm).
In an effort to arrest the descent, my 2P pulled back on the controls while maintaining 40 degrees angle of bank, and our red band, or "zipper," which indicates our minimum maneuver speed on the airspeed indicator, shot up to our indicated airspeed. The control column immediately went into "stick shaker," warning of an impending stall.
The system is controlled by an electric actuator, which blocks rudder travel, according to indicated airspeed.
Knowing these parameters, true and equivalent airspeeds could be estimated from the indicated airspeed using Equation (1).
Cruising speeds would be between 0.75 and 0.82 Mach, and 350 knots indicated airspeed, which equates to a true airspeed of 550 mph at 25,000 ft.
Our long range cruise setting, 1,400 rpm and enough manifold pressure to maintain about 160 mph indicated airspeed, we used about 50 gallons/hour.
Indeed, in the altitude range where birds are commonly a factor, up to 10,000ft, speeds are often restricted by regulation to 250 knots indicated airspeed, which would mean up to 300 knots true airspeed, depending on the ambient temperature.
According to the NATOPS manual, after a cat-shot with zero indicated airspeed and altitude, the first step is to eject!
At 14,500 feet and at an indicated airspeed of 160 knots, the aircraft shuddered and went into a spin to the left.
A racetrack pattern of about 1 x 5 nautical mi was flown at a 230-kt indicated airspeed and an altitude of 3,700 ft.
