Technical Subject Areas Flashcards
When should a student pilot obtain a medical certificate?
Prior to beginning training, but needed prior to solo flight
What is a Statement of Demonstrated Ability (SODA)?
Granted to a person whose disqualifying condition is not progressive, and does not impact airman duties
What are some medical conditions which might prevent the issuance of a medical certificate?
Clinical diabetes Coronary heart disease/heart attack Epilepsy Disturbance of consciousness Alcoholism Drug dependence Psychosis
Can a pilot act as PIC while having a known disqualifying medical deficiency?
No
What is the minimum medical certificate requirement for a practical test?
Third class
Is there a relationship between a person’s physical/mental health and his/her vision?
Yes, even minor illness can affect vision
What are some external factors that can degrade a pilot’s vision?
Smoke, haze, dust, rain
Windshield conditions
Light reflected off clouds, water, snow, desert terrain
Dim illumination (difficult to read charts)
Dark adaptation (20-30 minutes)
What are some optical illusions a pilot can experience in flight?
The “leans”-entering a bank slowly can create the illusion of banking in the opposite direction
Runway width illusion-narrow, aircraft appears high; wide, aircraft appears low
Runway/terrain slope illusion-upslope, aircraft appears high; downslope, aircraft appears low
Featureless terrain illusion-water/darkened terrain, aircraft appears high
Explain “see and avoid.”
Each person operating aircraft has responsibility to be vigilant for traffic, regardless of VFR/IFR rules
How much time should be spent looking outside the airplane versus inside the cockpit?
2/3-3/4 outside, 1/4-1/3 inside
Describe a good visual scanning technique.
Series of short (1 second), regularly spaced intervals of 10 degrees
What are the 4 dynamic forces that act on an airplane?
Lift-upward acting
Weight-gravity, downward acting
Thrust-forward acting
Drag-rearward acting
Define Bernoulli’s Principle.
Pressure of a fluid decreases with an increase in speed
Define Newton’s Third Law.
For every action, there is an equal and opposite reaction
Define airfoil.
Surface designed to generate lift from the air in which it moves
Define angle of attack.
Angle formed by the chord line of the wing and the relative wind
Define angle of incidence.
Angle formed by the chord line of the wing and the longitudinal axis of the aircraft
Define camber.
Curvature of an airfoil from leading edge to trailing edge
Define chord line.
Line drawn from leading edge to trailing edge of a wing
Define wing planform.
Shape of a wing when viewed from above
What is the relationship of forces acting on an airplane in straight and level, unaccelerated flight?
Lift = Weight, Thrust = Drag
What causes an airplane to turn?
Horizontal component of lift
Define static stability.
Initial tendency that the airplane displays after equilibrium is disturbed
Define dynamic stability.
Overall tendency the airplane displays after equilibrium is disturbed
How does wing downwash affect longitudinal stability?
Wing downwash passes over the horizontal stabilizer, producing downward pressure which balances the nose’s heaviness
Explain torque effect, as it relates to left-turning tendencies.
Rotation of the engine/propeller to the right causes the airplane to roll/yaw to the left
Explain the gyroscopic effect of the propeller.
A force acting on a spinning propeller will be deflected 90 degrees ahead of the rotation
Explain the corkscrewing effect of propeller slipstream.
Spiraling slipstream from the propeller strikes the left side of the vertical stabilizer, pushing the tail to the right and the nose to the left
Explain asymmetrical loading of the propeller (P-factor)
Descending propeller blade has a higher angle of attack, generating more lift, and pushing the nose to the left
What are the effects of speed on load factor?
The greater the speed, the greater the load capacity
At slow speeds, even abrupt control maneuvers or wind gusts can cause excessive loads
Explain the relationship between center of lift (CL) and center of gravity (CG).
CL is typically behind CG, making nose feel heavy
Horizontal stabilizer has a slight negative angle of attack to create a downward force to balance the airplane
What are the 2 types of drag?
Induced drag-product of lift
Parasite drag-created from the form/shape of airplane
Define mean aerodynamic chord (MAC).
Average distance from the leading edge to the trailing edge of the wing
What are some preflight actions/considerations for night flight?
Weather briefing (temp/dewpoint spread, possible fog)
Calculate wind directions and speeds (drift harder to detect)
Mark lighted checkpoints on chart
Check personal equipment (flashlights, handheld radios, etc.)
Thorough preflight of aircraft (all lights)
Check ground for obstructions before taxiing
What are some guidelines to follow when starting engine and taxiing at night?
Use lights/beacon prior to startup to alert persons in the area
Avoid high-draw equipment (landing light) during taxi to conserve battery
Taxi slowly
What are some guidelines to follow during takeoff and departure at night?
Use distant runway edge lights + landing light area to keep airplane on the centerline
Reference AI and VSI for positive rate of climb
Do not initiate turns until safe maneuvering altitude is reached
What procedures should be followed during approach and landing at night?
Allow plenty of time for pre-landing checklist
Maintain recommended speeds in pattern
Avoid a long, low final
Keep glidepath high enough to stay well clear of obstacles
Make sure DG is aligned with compass/use DG heading bug
Verify altimeter settings
Use VASI or ILS to help maintain approach path
What are the regulations concerning supplemental oxygen?
12500’-14000’ MSL-crew required to use O2 after 30 minutes
Above 14000’ MSL-crew required to use O2 the entire time
Above 15000’ MSL-every occupant must be provided O2
