WORKBOOK INTRODUCTION
This is the Master Copy of the Multi Engine Workbook. It does not teach any topics in depth but provides tools for helping students to memorize important items needed to fly safely and to pass their FAA Written Test and Checkride Exams.

RISK MANAGEMENT
Types of Risk
Total Risk = The sum of identified and unidentified risks.
Identified Risk = Risk that has been identified and determined.
Unidentified Risk = Risk that has not yet been identified.
Acceptable Risk = Risk that can be allowed to persist.
Unacceptable Risk = Risk that cannot be allowed to persist.
Residual Risk = Risk remaining after safety efforts have been fully employed.
Hazardous Attitudes
Checklists and Models
The 5P Model
Plan - Plane - Pilot - Passengers - Programming.
DETERMINING THE CRITICAL ENGINE
New Multi Engine Airspeeds
Vxse = Best Angle of Climb with a Single Engine.
Vyse = Best Rate of Climb with a Single Engine/Least Rate of Descent.
Vsse = Safe Single Engine speed.
Vmc = Minimum controllable airspeed.
Definitions
Vmc = Minimum control speed with the critical engine inoperative.
Critical Engine = The engine, that when failed, most adversely affects the handling and performance characteristics of the airplane.
Conventional Twin = Both aircraft propellers rotate clockwise as seen from the cockpit.
Counter-Rotating Twin = The propellers rotate opposite of each other (they both rotate inward).
Factors Used to Determine the Critical Engine
Remember the acronym “PAST.”
DETERMINING VMC SPEED
Factors Used to Determine Vmc Speed
Remember the acronym “SMACFUM.”
OTHER MULTI ENGINE FACTORS
Definitions
Absolute Ceiling = The aircraft cannot climb any higher.
Service Ceiling = The aircraft can yield a 100 FPM climb.
Single Engine Ceiling = The aircraft cannot climb any higher on a single engine.
Single Engine Service Ceiling = The aircraft can yield a 50 FPM climb on a single engine.
Accelerate Stop Distance = The runway required for the aircraft to accelerate to Vr, experience and engine failure, and then come to a complete stop.
Vyse Altitudes
For an aircraft operating below its Single Engine Ceiling, Vyse = Best Rate of Climb.
For an aircraft operating above its Single Engine Ceiling, Vyse = Least Rate of Descent.
Establishing Zero Sideslip with an Inoperative Engine
Bank Angle = 2 degrees toward operating engine.
Ball = One-third to one-half toward the operating engine.
Power vs Performance Loss with an Inoperative Engine
OEI Power Loss = 50%.
OEI Performance Loss = 80-90%.
