To instruct the student in proper preflight inspections, including use of the checklist, and the meanings of all items on the checklist. Included in this session is a discussion of the operation of elevators, ailerons, and rudder, flaps, and trim devices.

Checklist, aircraft documents (AROW), pilot's license and medical certificate, Hobbs meter, cockpit check (yoke and pedals, trim, brakes, gear handle, mags, mixture, power controls, switches, gauges, annunciators, flap handle), exterior check (wings and control surfaces, landing gear parts, lights, fuel and sumps, proper tying and chocking, pitot/static system, nose parts, oil check), how the control surfaces work

Airworthy aircraft. Preflight checklist (POH)

Ground lesson: 1 hour, 30 minutes
Student practice: 15 minutes
Ground lesson: (see lesson plan) motivate, explain, ask questions.
During ground lesson: Attend to explanation, ask questions, answer questions


Review: Introductory flight and use of primary controls.
Objective: Proper preflight inspection, and comprehension of operation of primary control surfaces.
Materials: Airplane, POH

INTRODUCTION: Attention/motivation: (1 minute)
You're driving along in your car and something goes wrong: it breaks down. What do you do? How about in an airplane: we can't exactly pull over to the side of the road, can we? This is the reason that we can just get in a car and turn the key, but in a plane, we really need to inspect the thing every time we're going to fly.

DEVELOPMENT: Overview and explanation: (60 minutes)
PREFLIGHT: Using the approved checklist (in POH), instructor does a complete preflight inspection, explaining to student what each item means, and what problems to look for.
1. In cockpit: student moves yoke and pedals while looking out window at what they do. Trim devices explained
2. Outside: movement of control surfaces and explanation of each primary control. Airflow and effect on aircraft explained.

Common errors: (30 seconds)
Not using the checklist
Not knowing what things on the checklist mean
Confusion about control surfaces: when one goes DOWN, that part of the plane goes UP (lift generated), and vice versa.

Oral evaluation/quiz and discussion questions:
After the instructor goes through the preflight, the student should do a preflight as well, while the instructor asks appropriate questions along the way: What are you looking for, here? What problems might you detect at this point? Etc.
