2011年7月29日 · I felt like the Vmc demo taught me a lot about flying, even flying singles. Did mine in a turbocharged twin at altitude, which obviously takes a little more care. But the lesson learned in asymetric thrust, AoA and power management is stick and rudder skills that translates to …

During a VMC demo, usually, the pilot will configure the airplane for engine-out flight and then pitch to an attitude that will create a 1 knot per second loss of airspeed. As pitch settings are fairly unchanging from flight to flight, this allows you to do the maneuver with more consistency.

2015年8月20日 · A VMC accident if it happens, is going to occur while still over the runway between 0 and about 25' AGL. You can't wait for the loss of directional control - it will happen too fast. It won't be anything like a VMC demo.

2022年4月26日 · it really depends on the aircraft and the airfoil designs used. trainers such seminoles, apache's, and the duchess have a more benign VMC roll over. higher performance twins like the baron and twin comanche have a more pronounced snap like entry. with any twin the problem is really bad once the rotation starts, due to the momentum of the ...

2021年6月11日 · Anybody doing VMC demos should be interested in the material covered — it might preserve their life. To cut to the chase, skip the first 40 minutes or so, then maybe go back to watch it all. Pay attention to the green arrow indicating airflow due to sideslip.

2012年9月20日 · Under the hood, Vmc demo, then shut down, secure one engine and restart, all under the hood holding heading and altitude. With the engine back running but simulated zero thrust, VFR into the traffic pattern for a SE landing, taxi back and pattern for an accuracy landing with both engines.

2015年5月6日 · Practicing Vmc demonstrations in an airplane that exhibits "very violent VMC characteristics" seems rather unwise when other, more docile trainers are available--trainers that allow Vmc demonstrations to be conducted as intended while still being forgiving enough to allow recovery from typical student mistakes without viciously snapping into an ...

2010年4月3日 · Then there is the altitude thing. One doesn't want to experience a true VMC demo at higher altitudes because one reaches the stall speed first with a lot of yaw. That leaves a true VMC demo only at lower altitudes but one doesn't want to do this at lower altitudes. But one doesn't want to do VMC demos at low altitudes.

2013年11月14日 · The Vmc demo is a required Task for that rating, and unless you do it at sea level if you do it per the PTS, you will be below redline when the yaw occurs. At a typical 3500-5000 AGL, the higher-than-SL density altitude means less than full power on the good engine and that lowers Vmc below the redline on the airspeed indicator.

2012年5月2日 · Your understanding of the PTS Vmc demo appears flawed. It is not a confirmation of the book Vmc value, but rather, is a demonstration of how the aircraft reacts when yaw control is lost due to reduced speed in an OEI situation, and then how to recover from that condition.
