PLT504: Instructional Aids

What code PLT504 covers, why the FAA tests it, and how to study Instructional Aids before your checkride.

Official FAA learning statement

Recall use of training aids - types / function / purpose

What this means for your checkride

Instructional aids, models, diagrams, videos, simulators, and slides, support learning when they are simple, relevant, and compatible with the lesson. A good aid clarifies a point words alone cannot, holds attention, and reinforces retention; a cluttered or off-topic aid distracts. The aid serves the objective, not the reverse.

Well-chosen aids improve retention, so the FAA tests the purpose and proper selection of instructional aids.

The common trap

Instructors add aids for flash. An aid earns its place only if it makes a point clearer or more memorable; complexity for its own sake gets in the way of learning.

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.
