RI-RS1 (I4701):  8/19/05
 
•	Vmca
* [FTI]  Minimum Single-Engine Controllable airspeed: 86 Kts.  Assumptions:  Takeoff Power, Windmilling Critical Engine, Gear up, Flaps takeoff setting (up), Full rudder deflection, 5deg AoB into good engine, full aft CG.  Left engine critical to lose, right creates a greater moment due to downward force of the blades on outboard side (P-factor).

•	Vmcg
* [NATOPS]: Min controllable airspeed (single engine, ground.)  63. Assumptions: No braking or nosewheel steering, gear down, flaps takeoff setting (up), takeoff power set, critical engine windmilling, full rudder deflection.  Lower air density reduces min airspeeds: lose some control authority, but lose a lot of thrust, reduces the asymmetry.
