To obtain a multi-engine rating to a private, commercial, ATP, or CFI certificate, the FAA requires an instructor endorsement and a practical test. A Knowledge test (written) is not required. The practical test includes a detailed oral test.
Pilots may take their original private pilot or other practical tests in a multi-engine airplane, in which case they will be subject to additional experience requirements. A pilot certificate obtained in such a manner will not include single engine piloting privileges (ability to deal with a total power loss is not demonstrated during multi-engine certification).
To be eligible for Airplane Multi-Engine rating, a person must:
- You must hold a current FAA Private Pilot or Commercial Pilot Certificate
- Obtain at least 40 hours of flight time in a multiengine airplane:
- Dual – 20 hours
- Solo – 20 hours
- Receive a written multi-engine endorsement from a certificated flight instructor (CFI)
- Pay FAA Examiner fee
- Pass FAA written, oral, and flight examination
