PLT207: Electrical System

What code PLT207 covers, why the FAA tests it, and how to study Electrical System before your checkride.

Updated September 2026 · Learning statement code · Pilot / Instructor

Official FAA learning statement

Recall electrical system - components / operating principles / characteristics / static bonding and shielding

What this means for your checkride

The light-aircraft electrical system runs on an engine-driven alternator or generator, a battery, a bus that distributes power, and circuit breakers or fuses for protection. An ammeter or loadmeter shows whether the system is charging or discharging.

Electrical failures affect radios, instruments, and lights, so the FAA tests the components and how to read a charging problem.

The common trap

Pilots panic at an alternator failure. The battery still powers essential loads for a while; the right move is to shed nonessential load and land.

Before your checkride (14 CFR 61.39)

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.
