Dynamic Engine Cut

JOINT ADVANCED MULTI-ENGINE T-44A

(6)

Maximum allowable aft CG (Center of Gravity), and

(7)

Full rudder deflection.

NOTES:

(1)

Vsse (91 KIAS) is single-engine safety speed; the speed above both Vmca and stall speed. Intentional

failing of one engine below this speed (airborne) is prohibited.

(2)

Vmcg (63 KIAS) is minimum control speed on the ground; the minimum speed at which the aircraft

can maintain runway centerline (using maximum rudder) with the critical engine windmilling, and

the opposite engine at full power. At speeds below 63 KIAS insufficient airflow exists to

directionally control the aircraft.

Basic concepts demonstrated in the Vmca Demonstration are common to all multi-engine aircraft.

Recognition is critical. The FAA training pamphlet excerpts starting on page 1-19 provide additional

insight into single-engine operations and will help you understand the maneuver.

Begin on a numbered heading at 150 KIAS with prop sync off. The following procedures will be utilized

to demonstrate Vmca after it has been thoroughly briefed:

(1)

Altitude

Minimum 8000' AGL.

(2)

Power

400 ft-lbs.

(3)

Flaps

Approach.

(4)

Gear

Up.

(5)

Props

Full forward.

(6)

Airspeed

Approximately 110 KIAS.

(7)

Power

Set idle on the left (critical) engine and smoothly apply maximum allowable power on

the right (operating) engine.

(8)

Attitude

Raise the nose so the airspeed continues to bleed off at a rate of approximately 1 knot

per second, keep the ball centered and trim while maintaining directional control with

rudder and 5 of bank into the good engine. Observe the rudder is full throw (or nearly

so) with full rudder trim applied, and a significant amount of aileron is required to

maintain 5 of bank. Note when the nose begins to yaw into the dead engine (visually

or by the turn needle and RMI ). This will occur at approximately 86 KIAS. Also note

the position of the rudder and ailerons.

NOTE: Some AOB may need to be taken out in order to simulate Vmc air due to the high-density altitude. Vmc air

decreases with altitude.

(9)

Recovery

Slowly reduce power on the operating engine and decrease AOA. As airspeed

accelerates above Vmca, smoothly reapply power on the operating engine. At 102 KIAS

execute a single-engine waveoff. The maneuver is complete when established in a climb,

clean, with 102 KIAS or greater.

NOTE: During this maneuver, the T-44 has been inadvertently spun in a clean configuration following rapid power

application. Use approach flaps to ensure stall speed is below Vmca. Single-engine power-on flight below 86 KIAS

is prohibited.

Dynamic Engine Cut

The dynamic engine cut simulates an engine failure immediately after takeoff with a windmilling prop. It

allows practice of critical single-engine skills at a safe altitude. Emphasis is on heading and airspeed

control, minimum loss of altitude, and completion of emergency checklist items.

Begin on a numbered heading at 150 KIAS with prop sync off. Maintain level flight prior to setting a

takeoff attitude. Utilize the following procedures:
