AN IMPOSSIBLE TURN?
REALITY CHECK ON TURNBACKS BY RICHARD G. MCSPADDEN, JR.
THE MARCH CRASH OF A BEECHCRAFT BONANZA A36 IN PEMBROKE PINES, FLORIDA, RESURFACED DEBATE ABOUT THE " TURNBACK, "
AN ENGINE-OUT COURSE REVERSAL SHORTLY AFTER TAKEOFF TO LAND IN THE OPPOSITE DIRECTION ON THE DEPARTING RUNWAY.
INITIAL NTSB REPORTS INDICATE THE PILOT OF THE BONANZA ATTEMPTED A TURNBACK WITH DISASTROUS RESULTS.
In April, the AOPA Air Safety Institute flew profiles at
Martinsburg (MRB), West Virginia's 8,800-foot-long, 150-footwide
runway to determine the feasibility of turnbacks.
The profile involved climbing between VX
and VY with full
power to a predetermined altitude, cutting power to idle,
delaying three seconds to simulate a startle period, then
pushing to best glide while entering a 45-degree-bank
turn back to the runway. Our lineup included me in my
150-horsepower, 1993 Piper PA-18 Super Cub with full gas;
AOPA Pilot Editor at Large Dave Hirschman solo in his Van's
RV-4 fully fueled; Hirschman and AOPA Vice President of
Flight Operations Dave Roy in a 1972 Beechcraft Bonanza A36
with a 300-horsepower Continental IO-550, full gas, and 40
pounds of baggage; and AOPA Director of Flight Operations
Luz Beattie alone in a fully fueled 1978 Cessna 172N.
Prior to the exercise, we all climbed to altitude and practiced
stalls, including stalls in 45 degrees of bank, to calibrate the
actual stall speeds at play during our turnback exercise. We
then established our minimum required turnback altitude
using airline pilot and CFI Brian Schiff's technique. We set a
climb profile, cut the power to idle, and began an idle power,
45-degree-bank turn at best glide for 360 degrees, noting the
altitude lost.
Educating pilots on improving their skills and enhancing GA safety is a core tenet of AOPA's Air Safety Institute and its educational programs.
