EAA Chapter 17 Young Eagles Ground School Outline
WELCOME
- Acknowledge sponsors: EAA 17, Host airport, etc.
- State purpose: To give some idea of what to expect and what's going on.
- Double-check everyone is registered.
TWO RULES
- Stay clear of the propeller! If magneto switch is broken, aircraft engines will run.
- Touch... but be gentle. Aircraft are delicate and lovable creatures.
AVIATION RELATED CAREERS
- Science
- Math
- Map Reading Skills
- English
AIRCRAFT TYPES
- Lighter-Than-Air
- Airships
- Gliders
- Rotorcraft
- Airplanes
- Powered Lift
PILOT'S CERTIFICATES AND RATINGS
- Sport Pilot: 17 years old, no medical certificate required (use drivers license),
minimum of 20 hours of flight training to obtain the certificate, VFR only, carry
no more than 1 passenger, may not receive compensation. Aircraft speed, size, and weight
restrictions apply. e.g. Fly for fun.
- Recreational Pilot: 17 years old, minimum of 30 hours of flight training to obtain the
certificate, limited to a 50 nautical mile range, VFR only, carry no more than 1 passenger,
may not receive compensation. Other restrictions apply. e.g. Fly for fun
- Private Pilot: 17 years old, minimum of 40 hours of logged flight training to obtain
the certificate, VFR only, may not receive compensation. Other restrictions apply.
e.g. Personal use in good weather.
- Instrument Rating: Private license required with a minimum of 125 hours of logged flight
time. At least 50 hours of flight time must be cross-country time (not a local flight).
Other restrictions apply. e.g. Fly in bad weather.
- Commercial Pilot: 18 years old, Private license required with a minimum of 250 hours
of logged flight time. Can fly for compensation or hire. Instrument rating not required,
but restricts what you can do. e.g. Charter pilots
- ATP (Airline Transport Pilot): Commercial license with instrument rating required, minimum
of 1250 hours of logged flight time, 50 actual IMC. Can fly for compensation or hire.
e.g. Airline pilots
AIRPLANES
- What are the physical differences between an airplane and a car?
- Airplane has wings; car doesn't
- Different controls (controls enable the operator to change the state of the machine)
- Basic controls - car: steering wheel, gas pedal, brake pedal
- Basic controls - airplane: yoke/stick, throttle, rudder pedals
- What physical change does each control make?
- Different instruments (instruments give the operator information about the
state of the machine)
- Basic instruments - car: speedometer, water temp, oil pressure...
- Basic instruments - airplane flight: airspeed, altimeter, compass, turn & bank...
- Basic instruments - airplane engine: tachometer, oil temp, oil pressure...
- What makes an airplane fly? (wing plus airspeed)
- Why does a wing look like it does? (maximize lift, minimize drag.)
- What does the pilot need to control? (speed, direction, altitude.)
- How does the pilot control speed? (S/He uses the fore/aft motion of the stick.
Forward makes the airplane go faster; backward makes it go slower.)
- How does the pilot turn the airplane? (S/He uses the right left motion of
the stick; this works because lift is always perpendicular to the wing --
Notice, birds do not have rudders. The rudder on an airplane compensates
for bad wing aerodynamics and to steer the airplane on the ground.)
- How does the pilot make the airplane go up and down? (S/He uses the
throttle. -- Remember, the stick controls speed, not altitude! Compare to
a car. If you want to go up a hill and maintain your speed, what must you
do? If you want to go down a hill and not speed up, what must you do?)
WHAT HAPPENS IN YOUR FLIGHT
- Pre-flight inspection - SAFETY is always #1!
- Get in airplane -- Do not get near propeller and fasten seat belt!
- Engine run up -- check controls and engine function
- Taxi and line up with runway
- Full power... airplane accelerates to flying speed
- Lift off at approximately 60 mph
- Pilot uses stick to adjust climb speed (approx 80 mph)
- At altitude pilot pushes forward on stick to speed aircraft up to
cruise speed (approx 100-120 mph) and cuts back on power to stop climb
- Pilot uses stick to change airplane's direction
- To prepare for landing, pilot pulls back on stick to slow aircraft down
(approx 80 mph) and reduces power to begin decent. Note: Stick goes back
but airplane goes down
- As aircraft gets closer to runway, pilot slows plane down more and more
so that touchdown occurs at approx 60 mph
- Taxi to ramp; shut down engine; remove seat belt; get out of airplane
- Thank your pilot!
