Preflight Procedures
- Planning
- Have a routine and follow it each and every time
- Ensure you have enough fuel and oil and properly mixed
- Always plan for EXTRA (fuel, oil, batteries, etc.)
- Ensure you have the proper clothes (remember it gets colder the higher you go)
- Allow for extra time if things change. (weather, winds, air traffic)
- Always ensure you are up to the task!
- NEVER TAKE UNDUE RISK

- Double check to ensure the aircraft is properly assembled and rigged IAW the manual.
- Safety Pins
- Lock Nuts
- Cables properly installed an free
- etc.
- Remember just one nut, bolt, safety pin could be a matter of a good flight or YOUR LAST FLIGHT!
Preflight Procedures

- The PIC should as a minimum do a walk around inspection of the aircraft.

Aerodynamics/Performance
- Critical Speeds
- Density Altitude Effects
- Carb Icing
- Weight and Balance
Aerodynamics/Performance
- Theories of aerodynamics
- Bernoulli? principle -Pressure decreases as velocity increases.
- This is reflected by the air moving on the upper surface of the wing traveling a farther distance causing less pressure and thus causing lift.
Aerodynamics/Performance
- Airfoils and lift
- An airfoil is a specially shaped surface designed to produce lift as air flow over it.
- Chord line - a line that passes through an airfoil from the leading edge to the trailing edge.
- Relative Wind - The direction from which the wind is moving when it reaches the airfoil.
- Angle of Attack - the Angle between the Chord Line and the Relative Wind.
Aerodynamics/Performance
- Control functions and axis of control
- Pitch (Lateral Axis)
- Elevator - Control Stick
- Control Bar - push/pull
- Roll (Longitudinal Axis)
- Aileron - Control Stick
- Control Bar - Right/left
- Yaw (Vertical Axis)
- Rudder - Rudder Peddles
Aerodynamics/Performance
- Aerodynamic forces
- Lift
- Weight
- Thrust
- Drag
- Straight and Level flight is when
- Lift = Weight
- Thrust = Drag
- Drag
- Induced - Drag that is caused by the production of lift < w/airspeed
- Parasite - Drag caused by friction air over the craft not related to lift > w/airspeed
- Turns Increase the load factors on the aircraft.
- Wake Turbulence
Aerodynamics/Performance
- Stalls/Spins
- Stall is when the Critical Angel of attack is exceeded.
- When one wing stalls and the other maintains lift. Caused by a stall during uncoordinated flight.
Aerodynamics/Performance
- Critical Speeds
- Vne = Never Exceed Speed
- Vy = Best Rate of climb - Best climb over Time
- Vx = Best Angle of climb - Best climb over Distance
- Vstall = Speed at which the Critical Angle of Attach is exceeded
- Va = Designed Maneuvering Speed
Aerodynamics/Performance
- Density Altitude Effects
- The altitude in standard air where the density is the same as that of the existing air.
- 3 Highs
- Pressure
- Moisture content
- Temperature
- Major changes in Altitude require the fuel mixture to be changed (Lean/Rich)
Aerodynamics/Performance
- Carb Icing
- The vaporization of fuel, combined with the decreasing air pressure as it flows through the carb, causes a sudden cooling of the mixture.
- Days of high moisture and a temperature between 20 - 70 Deg F.
- Commonly associated with reduction of power
- Indications of Carb Icing is a loss of RPM
- Roughness in engine operations
- When conditions exist add power for short Burts during idle down.
Aerodynamics/Performance
- Weight and Balance
- It is important that the maximum allowable gross weight is not exceeded and the center of gravity is within the allowable limits.
- Excessive weight reduces flight performance of the plane by:
Weather
- Standard conditions
- Fog and restrictions to visibility
- Lapse rate
- Dew point
- Stability characteristics
- Air masses and fronts
- Pressure and air circulation
Weather
- Wind Shear
- Hazardous weather
Weather
- Standard conditions
- The Earth? Atmospheres
- Troposphere - From the surface up to 20K??at the poles and 65K??at the equator
- Stratosphere - layer above Troposphere
- Mesosphere is the next higher atmosphere
- Thermosphere the outer atmosphere
- Are Based upon Sea level at 59 Deg. F
Weather
- Fog and restrictions to visibility
- Fog is formed as the temperature and the Dew point converge.
Weather
- Lapse rate
- Temperature of the air in the troposphere decreases with altitude at a rate of :
- Average = 2 deg C per 1,000 feet.
- Dry = unsaturated air is 3 deg C per 1,000 feet.
- Moist < dry dependent upon dew point
Weather
- Dew point
- The temperature to which the air must cool to become saturated by the water vapor that is already present in the air.
- Dew point spread is reported by the temperature in deg before the dew point (66-62)
- As the temperature and dew point converge, fog and rain are likely.
Weather
- Stability characteristics
- Clouds (High)
- Cirrus
- Cirrocumulus
- Cirrostratus
- Clouds (Middle)
- Altocumulus
- Altostratus
- Clouds (Low)
- Stratus
- Stratocumulus
- Cumulus
Weather
- Air masses and fronts
- Air masses - When a body of air comes to rest or moves slowly over an extensive area having uniform properties of temperature and moisture, the air takes on the same properties.
- Fronts - As air masses move out of their source regions, they come in contact with other air masses with different characteristics. The zone between two different air masses is a frontal zone or ?ront.?? Across this zone, temperature , humidity, and wind often change rapidly over short distances.
- Types
- Cold Front is the leading edge of a cold air mass.
- Warm Front is the leading edge of a mass of warm air.
Weather
- Pressure
- High pressure pusses the air toward the lower pressure
- The tighter the Isobars are on the weather map the stronger the wind moving parallel the isobars
- Air circulation
- High Pressure has a clock-wise rotation
- Low Pressure has a counter clock-wise rotation
Weather
- Wind Shear
- Caused by two air masses moving past each other. As the air masses rub together, a shear zone or turbulent mixing area is formed.
- Sudden shifts in direction and strengths of winds make this EXTREMELY DANGEROUS.
Weather
- Hazardous weather
- Thunderstorms - Towering Cumulus
- Stages
- Cumulus Stage (early)
- Mature Stage (fully developed)
- Dissipation Stage
