PLT223: Multiengine Engine-Out
What code PLT223 covers, why the FAA tests it, and how to study Multiengine Engine-Out before your checkride.
Recall flight operations multiengine - engine inoperative procedures
What this means for your checkride
With one engine out on a light twin, asymmetric thrust yaws and rolls the airplane toward the dead engine. Vmc is the minimum speed at which you can keep directional control with the critical engine failed and the other at full power. You identify, verify, and feather the failed engine and hold at least Vmc, ideally blue-line (Vyse) for the best single-engine climb.
An engine failure in a twin is a demanding, time-critical event, so the FAA tests Vmc, the critical engine, and the identify-verify-feather procedure.
Pilots pitch for altitude after a failure and slow below Vmc. Below Vmc you lose directional control; you lower the nose to hold at least Vmc, even at the cost of altitude, before sorting out the engine.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
