What you will learn
- Understand the critical engine concept and all factors that affect VMC.
- Execute the identify-verify-feather engine failure sequence correctly.
- Apply zero-sideslip technique for maximum single-engine performance.
- Calculate and interpret multi-engine takeoff performance data.
- Manage multi-engine systems including propeller feathering and crossfeed.
- Make sound engine-failure decisions including when to continue vs. land immediately.
Topics covered
Critical Engine and VMC
Why the critical engine matters, P-factor effects on thrust arm, factors affecting VMC, VMC demonstration procedures, and counter-rotating propellers.
Engine Failure Procedures
Identify-verify-feather sequence, engine failure before and after VMC, accelerate-stop distance, single-engine service ceiling, and rejected takeoff criteria.
Multi-Engine Aerodynamics
Asymmetric thrust and yaw, P-factor in twins, zero-sideslip concept, bank into operative engine, and drag sources during single-engine flight.
Multi-Engine Performance
Vyse (blue line), Vxse, Vsse, accelerate-go distance, single-engine climb gradient, and the 80% performance loss with one engine inoperative.
Multi-Engine Systems
Propeller feathering mechanisms, crossfeed fuel system, electrical load shedding, unfeathering accumulators, and dual-engine preflight procedures.
Multi-Engine Decision-Making
Post-engine-failure climb/descend decision, high-density-altitude considerations, pre-takeoff briefing, and when to land straight ahead vs. continue.
Emergency Operations
Engine fire procedures, systems failures, propeller runaway, rejected takeoff criteria, and single-engine approach and landing techniques.
Single-Engine Instrument Approaches
One-engine-inoperative ILS procedures, OEI circling approaches, workload management, and altitude/configuration management during single-engine approaches.
Prerequisites
- •Private Pilot Certificate (minimum) or Commercial Pilot Certificate.
