Multi-Engine Rating (MEP FAA)

This rating allows you to qualify at private or professional level, in order to expand your privileges by having the right to be Pilot in Command on an airplane with 2, 3, 4, or even 8 engines!
The training, both theoretical and practical, focus on the failure of one engine, the effects of induced roll and yaw, the minimum speed to be maintained, and how to land safely if this kind of emergency occurs.

Although very interesting itself, this rating will be truly beneficial only if you really intend to pilot a twin-engine, the principles and mechanics of flight considered at this occasion not being applicable to single engine airplanes.

The BFR (Biannual Flight Review)

As you will learn or already know, the U.S. licenses never expire, but to remain valid, must be validated every 24 calendar months by a Biennial Flight Review, which may be conducted by an FAA instructor or by an FAA examiner, and which consists of a minimum of 1 hour ground training, and 1 hour of flight. During this time, you must demonstrate you are capable of achieving the same level of performance while performing the checkride maneuvers of your license (CPL or PPL checkride) as the day of the test. If this is not the case, your instructor will tailor for you a specific training program to help you regain your skills before issuing the endorsement saying that you have passed this BFR. You will just have to paste this endorsement in your logbook, and you are ok for another 2 years! Even if you let this validity expire, the procedure is exactly the same!

The IPC (Instrument Proficiency Check)

Unlike the BFR, the IPC will only be necessary for an Instrument Rating (IFR FAA) that hasn't been maintained in validity. For an IFR FAA to be kept valid, you must have logged in your logbook 6 instrument approaches, holdings procedures, and intercepting and tracking radials, within the last 6 months preceding the planned IFR flight. If this is not the case, you cannot file an IFR flight plan under your name, but you still have another 6 months (the grace period) to perform these procedures in VFR conditions, with a Safety Pilot, a person holding at least a private pilot license, who will ensure the safety of the flight while you're under your hood immersed in your procedures. If you let this second deadline expire, you need to take an IPC with a FAA instructor or an FAA examiner, to demonstrate that you still have the skill level that you had during the IFR FAA checkride. When this happens, you will be given a new endorsement to paste into your logbook, that allows you to file an IFR flight plan as the Pilot in Command (PIC).
