Lesson Background - Airplane Familiarization and Preflight
Personal
IM SAFE acronym.
• Illness
• Medication
• Stress
• Alcohol
• Fatigue
• Emotion
Illness
• Safest rule not to fly when ill.
• Illness can produce fever and distracting symptoms that can impair judgment, alertness and memory.
• FAR’s prohibit flying with a known medical condition which would prevent the pilot from meeting the standards for a medical certificate.
Medication
• Over the counter and prescription medications can impair performance.
• Medications can make a pilot more susceptible to hypoxia.
Stress
• Affects performance indirectly.
• Various stressful situations occupy thoughts and attention needed while flying.
• Attempt to resolve problems on the ground to avoid poor judgment in the air.
Alcohol
• FAR’s say 8 hours bottle to throttle.
• Must not be under the influence.
• Approximately 3 hours per drink for the body to destroy alcohol.
• Pilot is more susceptible to disorientation or hypoxia.
Fatigue
• Acute: Short term (prevented by adequate rest, sleep, exercise and nutrition).
• Chronic: Occurs form inadequate time between episodes of acute fatigue. Performance continues to decline.
Emotion
• Feelings of anger, depression and anxiety can also decrease alertness.

• Poor emotional stability can lead to unnecessary risk taking and poor judgment.
Medical Certification:
• All pilots must possess a valid medical certificate to exercise the privileges of their airman certificates.
• Private: Third Class. Good for 24 months.
• Commercial: Second Class. Good for 12 months.
• ATP: First Class. Good for 6 months.
Signoffs/Currency
• Student: Must have received and logged flight instruction in the aircraft to be flown. Must be approved by instructor.
• Passenger Carrying: (Day) Must have made three takeoffs and landings within the past 90 days. (Night) Must have made three takeoffs and landings at night within the past 90 days to a full stop.
• Must have biennial flight review within the past 24 months if a recent rating has not been achieved. Completion of a Wings program phase counts as a biennial.
Certificates
• A pilot must hold a current pilot certificate and rating appropriate for the aircraft to be flown.

Aircraft Components
In order to facilitate the discussion of preflighting an airplane, the general components of the aircraft must be understood.

Flight Controls
Elevators
The elevators provide control of the pitch altitude about the airplane’s lateral axis. Elevators are the key to controlling the angle of attack. When the control wheel (yoke) is pulled toward the pilot, the nose pitches up.

When the control wheel (yoke) is pushed forward, away from the pilot, the nose pitches down.
Ailerons
The primary use of the ailerons is to bank, or roll, the airplane around the longitudinal axis. Banking the wings results in the airplane turning in the direction of the bank. When the control wheel (yoke) is turned to the left, the left aileron is raised and the airplane rolls to the left.
When the control wheel is turned to the right, the right aileron is raised and the airplane rolls to the right.
Rudder
The rudder is used to control the direction (left or right) of yaw about the airplane’s vertical axis. When the left rudder is pushed, the nose points to the left.
When the right rudder is pushed, the nose points to the right.

Cockpit Controls
Yoke
Hold the yoke with your left hand. Your grip should be firm but relaxed.
Rudder Pedals
Place your heels on the floor and toes, or the balls of the feet, on the rudder pedals.
Brakes
To apply the airplane breaks, depress the top of the rudder pedals. Do the same when setting the parking brake.
Throttle
Operate the throttle with the right hand. Hold the throttle so that small changes can be made smoothly. Use several fingers to act as a stop against contact with the panel or quadrant. Do not hold the throttle entirely by its knob or lever handle.

Flaps Flaps
Flaps increase the wing’s lift by increasing its area or its camber. Flaps also cause drag because they extend beneath the wing. The lift/drag ratio is determined by the degree of flap extension. Using flaps lowers the wing’s stalling speed, and increases the rate of descent without an increase in airspeed.

Trim tab Trim tab
The purpose of the trim tab is to relieve control pressure on the flight controls. Set trim for airspeed (attitude) desired. The trim tab is operated by the trim wheel.
