COMM.X.B — VMC Demonstration (AMEL, AMES)

Objective: To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with a VMC demonstration.

Knowledge

The applicant demonstrates understanding of:

• CA.X.B.K1Factors affecting VMC and how VMC differs from stall speed (VS).
• CA.X.B.K2VMC (red line), VYSE (blue line), and VSSE (safe single-engine speed).
• CA.X.B.K3Cause of loss of directional control at airspeeds below VMC.
• CA.X.B.K4Proper procedures for maneuver entry and safe recovery.

Risk Management

The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing:

• CA.X.B.R1Improper airplane configuration.
• CA.X.B.R2Maneuvering with one engine inoperative.
• CA.X.B.R3Distractions, loss of situational awareness, or improper task management.

Skills

The applicant demonstrates the ability to:

• CA.X.B.S1Configure the airplane in accordance with the manufacturer’s recommendations, in the absence of the manufacturer’s recommendations, then at VSSE/VYSE, as appropriate, and:
  • CA.X.B.S1aa. Landing gear retracted
  • CA.X.B.S1bb. Flaps set for takeoff
  • CA.X.B.S1cc. Cowl flaps set for takeoff
  • CA.X.B.S1dd. Trim set for takeoff
  • CA.X.B.S1ee. Propellers set for high RPM
  • CA.X.B.S1ff. Power on critical engine reduced to idle and propeller windmilling
  • CA.X.B.S1gg. Power on operating engine set to takeoff or maximum available power
• CA.X.B.S2Establish a single-engine climb attitude with the airspeed at approximately 10 knots above VSSE.
• CA.X.B.S3Establish a bank angle not to exceed 5° toward the operating engine, as required for best performance and controllability.
• CA.X.B.S4Increase the pitch attitude slowly to reduce the airspeed at approximately 1 knot per second while applying rudder pressure to maintain directional control until full rudder is applied.
• CA.X.B.S5Recognize indications of loss of directional control, stall warning, or buffet.
• CA.X.B.S6Recover promptly by simultaneously reducing power sufficiently on the operating engine, decreasing the angle of attack as necessary to regain airspeed and directional control, and without adding power on the simulated failed engine.
• CA.X.B.S7Recover within 20° of entry heading.
• CA.X.B.S8Advance power smoothly on the operating engine and accelerate to VSSE/VYSE, as appropriate, ±5 knots during recovery.
