Commercial multi-engine add-on: questions to ask a school

Start with the certificate you already hold

This checklist focuses on adding airplane multiengine land, or AMEL, to an existing commercial airplane single-engine land certificate. Bring your certificate, ratings, limitations and logbook for the instructor to review. If you are earning your initial commercial certificate in a twin, or adding an airplane category from another category, ask for a plan tailored to that different starting point.

For this additional airplane class rating, 14 CFR 61.63(c) requires an instructor endorsement and a practical test. It does not prescribe a fixed training-hour minimum for this airplane class add-on. A package containing a stated number of hours is therefore a proposed course allowance, not proof that you will be ready when those hours run out.

Ask the instructor to explain the test scope

The FAA Commercial Pilot for Airplane Category ACS includes an additional-rating task table for AMEL. Ask the instructor to walk through the column matching the commercial ratings you hold. The ACS also permits an evaluator to assess competence in remaining areas and tasks, so the table is not a reason to ignore underlying knowledge.

Discuss your instrument rating and any previous multiengine instrument proficiency demonstration. The table includes conditions for instrument tasks, and the ACS separately addresses removal of the Airplane Multiengine VFR Only limitation. Have the instructor explain which tasks and potential limitations apply to your proposed test.

Match preparation to the actual aircraft

Ask which aircraft model and avionics configuration the school expects you to train and test in. Request its assigned study materials before arrival, then confirm which aircraft-specific documents the instructor wants you to use. A general video cannot settle how a particular school's aircraft is equipped.

Ask for a ground-training outline covering the aircraft's systems, performance and limitations. Also ask how the instructor will introduce and assess multiengine tasks. This is a planning conversation; practice emergency procedures only through appropriate supervised instruction.

• What should I study before the first appointment, and how will you check my preparation?
• Will I use the same aircraft and instructor throughout the course?
• If either becomes unavailable, who explains the effect on training and the test?

Separate readiness from a reserved test date

Ask when the instructor will review progress and what happens if more preparation is needed. A useful answer names a review point and a way to revise the plan. It should not depend entirely on a travel departure date or an advertised course length.

Clarify who arranges the examiner, whether a date is confirmed or only requested, and who coordinates aircraft availability for the test. Ask how weather, maintenance, instructor availability or a postponed test would affect your reservation and travel plans. Get cancellation and rescheduling terms in writing before paying.

Bring home six clear answers

Use one page to capture these answers for each course you are considering. Mark an unanswered item as an open question instead of filling it with an assumption. Ask for a written estimate tied to this specific course scope, including how extra flight or ground instruction and test-day aircraft use are billed.

• Starting point: which existing commercial ratings and limitations did the instructor review?
• Outcome: what exact rating and test scope does the course cover?
• Preparation: which aircraft materials and ground topics should be ready before arrival?
• Readiness: when is progress reviewed, and how is additional training arranged?
• Logistics: who confirms the instructor, aircraft and examiner schedule?
• Contingency: what costs and rescheduling terms apply if the original plan changes?
