* Lower Red Radial: Minimum controllable airspeed, VMC, for a
multiengine airplane operating with a failed engine.
The pilot held the appropriate certificates and ratings for operation of the
multiengine airplane in instrument conditions, but no clearance had been issued for operation in instrument meteorological conditions.
However, the circling approach, the landing task and the
multiengine airplane tasks must be accomplished in an aircraft or full-flight simulator (level B, C, or D), according to the ACS.
When flying a
multiengine airplane, however, they also need to know how to lose control.
According to the FAA's Airplane Flying Handbook, FAA-H-8083-3A, here's why: "With a single-engine airplane or a
multiengine airplane with both engines operative, sideslip is eliminated when the ball of the turn and bank instrument is centered ...
If you operate under Part 91 Subpart F, Large and Turbine-Powered
Multiengine Airplanes and Fractional Ownership Program Aircraft, then [section] 91.503 applies to you.
Now, a newly revised Advisory Circular from the FAA, AC 120-76D, Authorization for Use of Electronic Flight Bags, clarifies and simplifies many aspects of EFB use for commercial operations and drops guidance for fractional operations under FAR 91 Subpart F, "Large And Turbine-Powered
Multiengine Airplanes And Fractional Ownership Program Aircraft," placing those operations in an older AC, 91-78, "Use of Class 1 or Class 2 Electronic Flight Bag."
Subpart F, Large and Turbine-Powered
Multiengine Airplanes and Fractional Ownership Program Airplanes do have a requirement for checklists, as does Subpart K that specifically governs fractional operators.
Multiengine airplanes were more susceptible to structural failure as a result of fire and heat behind the engine compromising the wing structure and, in extreme cases, causing the wing to separate.
The nine GA organizations were responding to a March 14, 2016, proposed rule from the FAA that would remove "current prescriptive design requirements" and replace them with "performance-based airworthiness standards." The proposal also would "adopt additional airworthiness standards to address certification for flight in icing conditions, enhanced stall characteristics, and minimum control speed" for
multiengine airplanes. The proposal responds to a Congressional mandate enacted in 2013.
