is assured you can select flaps LDG and decelerate below Vyse to Vref. You can also
choose to maintain the current configuration and continue with flaps TO, but your speed
will be Vref+10 and landing distance will increase.
See diagrams for single engine precision and non-precision approach profiles.
The pilot should always consider coordinating with ATC alternate missed approach
instructions of a runway heading climb if the published missed approach procedure
cannot be safely flown single engine.
NOTE
During actual aircraft flight training, the engine failure will be induced by the instructor
slowly bringing one of the throttles to idle. This will occur at an altitude at least 500’
AGL and airspeed not less than Vyse.
Visual Pattern
A single engine traffic pattern should be flown as much like a normal pattern as
possible. As with any single engine operation, airspeed discipline is critical—do not fly
slower than Vyse. As described earlier, do not attempt any turns until at least 400’ AGL
or minimum safe altitude. After reaching pattern altitude, fly the downwind leg at the
normal 150 knots, if possible. Delay gear extension and flaps TO until abeam the
touchdown point of the desired runway and/or ready to begin descent (“gear down to go
down”). Maintain normal pattern airspeeds. When wings level on final and landing is
assured, select flaps LDG. At this point, slow to Vref (or Vref + 15 if landing with flaps
TO), and execute a normal landing.
Missed Approach
In the event that a single engine missed approach is necessary, proper aircraft control is
essential. Simultaneously advance throttle to APR thrust, apply appropriate rudder for
coordinated flight and set an initial pitch attitude following the flight director. At positive
rate of climb or if ground contact is not imminent, raise the gear. Fly at Vyse. When
above 400’ AGL or when terrain is not a factor, select flaps UP and accelerate to the
new flaps UP Vyse.
See diagram for single engine missed approach profile.
NOTE
During actual aircraft flight training, if single engine climb performance is marginal, the
instructor will discontinue the maneuver by directing the pilot to resume use of both
throttles.
