Steep turns (AFH 9-1 / PTS 2-19 PVT and 2-22 COMM)

Conduct clearing turns and clear the area BGUMPFFS – Boost pumps – on, Undercarriage - up, Mixtures – lean for

cruise, Props – 2300 RPM Flaps - up, Flaps (cowl) - closed, Seat belts - fastened Verbally state "I will use xxx-degrees (d), 3,500 feet, and 120 KIAS” Heading bug on xxx-d Look and announce, “clear left/right Smoothly roll into a 45-d +/- 5-d bank

Maintain altitude with elevator – use horizon slicing through windshield as

primary reference for bank and altitude control Apply power to maintain 120 KIAS, trim to relieve control pressure Announce 180-d through turn Roll out the number of degrees equal to half your angle of bank (45-d / 2

= about 23 -d).

Airspeed below 110 KIAS, Flaps – down incrementally

Conduct a level deceleration to normal approach speed

Fly a simulated base to final

Reduce power and smoothly raise nose to an attitude that induces a stall

As the stall occurs, recover promptly by simultaneously reducing the angle of attack, increasing power to maximum allowable, and leveling the wings

Focus on minimum altitude loss

Recovery (identical to Balked Landing)

Simultaneously apply maximum power and pitch for Vy

directed by MEI/examiner

Mixture – decide whether to shutdown or land

Vmc Demonstration (AFH 12-2 / PTS 2-34 PVT AND 2-35 COMM / POH 4-18)

As altitude increases, the Duchess produces less power because of the reduced air density entering the engine induction system. The power loss will result in a Vmc lower than stall speed at higher altitudes. Therefore, always recover at the first indication of loss of directional control, stall warning, or buffet (See Figure 12-21, page 12-30, AFH).

Vmc defined: minimum control speed with the critical engine inoperative Under the small airplane certification regulations currently in effect, the flight test pilot must

be able to (1) stop the turn that results when the critical engine is suddenly made inoperative within 20-d of the original heading, using maximum rudder deflection and a maximum of 5-d bank, and (2) thereafter, maintain straight flight with not more than a 5-d bank.

Performing the Vmc Demonstration:

Conduct clearing turns and clear the area

BGUMPFFS – Boost pumps – on, Gas (fuel selectors) – on, Undercarriage – up, Mixtures – full forward, Props – full forward, Flaps – up, Flaps (Cowl) – open, Seat Belts – fastened.

Select an entry altitude and heading

Power – 13” MP

Airspeed below 90 KIAS – close left throttle (left cowl flap closed)

Right throttle – full open without delay

Maintain heading by banking 5-d into operating engine and applying rudder

Increase pitch attitude at approximately 1 knot per second

At approximately 85 KIAS

Recover at first sign of:

Loss of directional control First indication of stall

Recover by simultaneously reducing power on the operating engine and

decreasing the angle of attack as necessary to regain control within 20-d of original heading

Continue recovery by increasing power slowly on operating engine, then increasing power on simulated failed engine; accelerate to 120 KIAS with minimal loss of altitude

Re-establish cruise at 120 KIAS and adjust cowl flaps

Standards:

Recognize indications of loss of directional control, stall warning or buffet

Recover promptly by simultaneously reducing power sufficiently on the operating engine while decreasing the angle of attack as necessary to regain airspeed and directional control

Recover within 20-d of the entry heading and advance power smoothly on operating engine and accelerate to Vxse / Vyse, as appropriate, +/- 5 knots, during the recovery.

Drag Demonstration

The Drag Demonstration proves that the optimal rate of climb occurs at Vyse in a clean

configuration. The demo also illustrates performance penalties when an aviator does not fly a light twin at

the optimal configuration. Performing the Drag Demonstration:

Mixtures - full forward, Props- full forward, Gear - up, Flaps - up, Cowl flaps –

open
