Return To Dual Engine Flight Following Single-Engine Training

JOINT ADVANCED MULTI-ENGINE T-44A

The SSE waveoff is a demanding maneuver requiring precise aircraft control and expedient execution of

procedures. Climb performance is directly proportional to how well the maneuver is executed. Limited

power margins (especially at altitude) dictate exact execution.

Level off on a 1000' altitude plus 800 (i.e., 4800, 5800, etc.), 120 KIAS, on a numbered heading. One

technique is to align the Course Deviation Indicator (CDI) with your heading, tail at the top. This simulates

800' on the downwind leg of the traffic pattern. The IP will simulate a single-engine by reducing one

power lever to idle or simulating a situation requiring an engine to be secured. "Power up, rudder up, clean

up." Complete the Emergency Shutdown Checklist without delay. The IP will call "Approaching the 180".

Lower the flaps and gear and complete the Landing Checklist. Immediately start a descending left turn to

arrive at the "90" at 500' and 120 KIAS (minimum 110 KIAS). Continue the turn to "final," rolling out on

the head of the CDI at 250' with a minimum of 110 KIAS, maximum of 120 KIAS. Smoothly place the

props full forward; when IP calls "Waveoff," execute the following procedures:

(1)

Power

Maximum allowable. Simultaneously transition to a climb attitude. Anticipate

significant rudder with power. Keep the ball nearly centered ( to out towards the

operating engine) while using up to 5 AOB into the operating engine. Maintain a

minimum of Vxse (102 KIAS), a maximum of Vyse (110 KIAS), preferably Vyse. Level off

or descend if required to maintain flying speed. Under no circumstances allow speed to

approach Vsse (91 KIAS).

(2)

Flaps

Approach (unless already up). Immediately select flaps to approach.

(3)

Gear

Up. The gear is raised when the descent has been stopped or there is no possibility of

touchdown on a prepared surface. Do not delay in raising the gear.

(4)

Flaps

Up. Immediately after selecting gear up, raise the flaps. Anticipate a slight attitude

adjustment to prevent settling.

(5)

Props

Reduce to 1900 RPM after CP reports "Gear up." In an actual situation, one prop would

be feathered. A positive single-engine climb is not possible in any configuration with a

windmilling prop.

Direct the CP to make a waveoff call. The maneuver is complete at the IP's discretion, when established in

a clean climb, minimum of 102 KIAS (preferably 110 KIAS), with the aircraft trimmed and in balanced

flight.

124.

returning to dual-engine flight is simple, but must be performed smoothly, especially if an engine has

actually been secured or prop actually feathered. The objective is to allow the engine and prop to smoothly

come up to speed. If power is added abruptly, prop or engine acceleration limits may be exceeded, and

yaw may be excessive. Maximum torque is 2100 ft-lbs for 2 seconds. Never add power to a feathered prop

without placing the prop out of feather and allowing it to come up to idle RPM first. Slowly add power,

allowing time for engine spool-up and smooth prop acceleration, then continue to advance power to match

the other engine. Smoothly adjust both power levers as required, match props to 1900 RPM and fine tune

to reduce cabin noise.

Vmca Demonstration. This maneuver will only be flown by the instructor. It demonstrates single-engine

flight characteristics at low speed and high power. Vmca is the airspeed below which it is not possible to

maintain heading despite maximum rudder deflection and 5 AOB into the operating engine. The Federal

Aviation Administration (FAA) certifies Vmca under the following conditions:

(1)

Takeoff power set on the operating engine,

(2)

Critical engine windmilling (left engine in the T-44),

(3)

Flaps at takeoff setting,

(4)

Gear up,

(5)

5 AOB into operating engine,
