within 20° of the entry heading, accelerating to VXSE or VYSE (as designated by the pilot examiner) +10/-5 knots, and you’ve passed this task on the Multiengine Rating Practical Test at the Private Pilot level.Why do twin-engine pilots learn to fly the VMC Demonstration? Most say: “In order to pass the checkride.” The FAA’s Airplane Flying Handbook doesn’t emphatically state the purpose of this demonstration, but does say that:A thorough knowledge of the factors that affect VMC, as well as its definition, is essential for multiengine pilots, and as such an essential part of that required task....Seemingly, the VMC Demonstration is the ultimate “circus trick” maneuver, one taught for the sole purpose of giving pilots something on which to be evaluated. After all, you have to be at or below VMC (red radial) speed in order to perform this maneuver.
