Requirement 1

• A) Define “aircraft”- an airplane, helicopter, or other machine capable of flight• What are the operation of the following: Jet Engine:

It is a reaction engine discharging a fast moving jet that generates thrust by jet propulsion. Piston:

Its purpose is to transfer expanding gas in the cylinder to the crankshaft for the purpose of ejecting the fluid in the cylinder.

Turboprop:

It is a turbine engine that drives a propeller

Requirement 1• B) Point out on a model airplane the forces that

act on an airplane in flight. What are they?

2. Lift

3. Weight

1. Thrust 4. Drag

Requirement 1• C) Explain how an airfoil generates lift, how the primary

control surfaces (ailerons, elevators, and rudder) affect the airplane’s attitude, and how a propeller produces thrust.

• How?

Here’s how!Lip right Airfoil

Inverted Airfoil

Streamlines crowned together low local static pressure.

Lift can be achieved in either direction

Requirement 1

Requirement 1

• What does the following do to the aircraft?Rudder:

affects aircraft heading (orientation)Elevator:

helps with pitch (aircraft steepness)Aileron:

helps generating rolling motion in an aircraft

C)

Requirement 1

D) Demonstrate how the control surfaces of an airplane are used for takeoff, straight climb, level turn, climbing turn, descending turn, straight descent, and landing.

• Straight Climb- Increasing altitude with no turn.

• Level Turn- Turn no more than 20° bank.

• Climbing Turn- Turning no more than 20° bank due to landscape or obstruction. Ex: Stratosphere Las Vegas

• Descending Turn- Turning no more than 20° bank due to landscape or obstruction on approach. Ex: Stratosphere Resort Las Vegas

• Straight Descent- Flying straight in with little to no heading modifications or decreasing altitude with no turn.

• Landing- Gently putting nose up and let front part of aircraft touch down.

Requirement 1Quick Tip

Requirement 1

• Private Pilot License- – You may only make VFR Flight plans unless you have an instrument

rating.

• Instrument Rating-– You can make IFR flight plans and go through Class Bravo Airspace

without having to take off and land within airspace; you may go in if you have permission.

• Recreational Pilot License- – It requires less training and privileges you must need 5 hours of cross

country flight time

• Sport Pilot- – You may fly light sport aircraft only license that does not require a

health certificate.

Requirement 2

Do TWO of the following:• A) Take a flight in an aircraft, with your parent’s permission. Record the date, place,

type of aircraft, and duration of flight, and report on your impressions of the flight.• B) Under supervision, perform a preflight inspection of a light airplane.• C) Obtain and learn how to read an aeronautical chart. Measure a true course on the

chart. Correct it for magnetic variation, compass deviation, and wind drift to determine a compass heading.

• D) Using one of many flight simulator software packages available for computers, “fly” the course and heading you established in requirement 2c or another course you have plotted.

• E) Explain the purposes and functions of the various instruments found in a typical single-engine aircraft: attitude indicator, heading indicator, altimeter, airspeed indicator, turn and bank indicator, vertical speed indicator, compass, navigation (GPS and VOR) and communication radios, tachometer, oil pressure gauge, and oil temperature gauge.

• F) Create an original poster of an aircraft instrument panel. Include and identify the instruments and radios discussed in requirement 2f.

Requirement 3

Do ONE of the following:• A) Build and fly a fuel-driven or battery-powered

electric model airplane. Describe safety rules for building and flying model airplanes. Tell safety rules for use of glue, paint, dope, plastics, fuel, and battery pack.

• B) Build a model FPG-9. Get others in your troop or patrol to make their own model, then organize a competition to test the precision of flight and landing of the models.
