What caps the troposphere?
What caused the need for regulation in the aviation industry?
The existing airmail business gave birth to the airline business. The government stepped in with regulation to promote innovation, safety, and provide incentives.
What are the four forces of flight?
Lift; Drag; Thrust; and Weight
Ailerons are used to _____ about the _____ axis.
Ailerons are used to roll about the longitudinal axis.
In which layer of atmosphere does most weather happen on Earth?
Troposphere
What are the effects of deregulation?
More affordable air fares
Decrease in customer service
More crowded passenger cabins with less room between seats
The proliferation of low-cost air carriers
What is interference drag?
Turbulent air caused by an intersection (ex. wing and fuselage)
Name the 4 strokes of the combustion engine.
Intake, Compression, Combustion, Exhaust
What is the standard adiabatic lapse rate in the troposphere?
-2* C / 1000 ft elevation
What force is induced drag related to?
lift
Which combustion engine stroke is being described:
increases the pressure and temperature of the fuel-air mixture by decreasing the volume inside the cylinder?
Compression Stroke
As altitude increases, what happens to temperature?
Temperature decreases
What are the three types of parasitic drag?
Form, Interference, and Skin Friction
Which part of the propeller blade travels the FASTEST?
Tip
As altitude decreases, what happens to atmospheric pressure?
Pressure increases as altitude decreases.
If you accelerate in straight and level flight without changing mass, what must have happened to the aircraft's thrust force?
Increased
What are the sections of a turbine engine from front to back?
Inlet (Intake)
Compressor
Combustion
Turbine
Exhaust
What are some characteristics of LOW CLOUDS?
Clouds can change rapidly; Can include fog
What is the coanda effect?
The tendency of a fluid jet to stay attached to a convex surface
Draw the internal supports of a WING including spar and ribs.
Jessi checks :)
What are some characeristics of MIDDLE clouds?
Can produce turbulence and icing
What happens when separation occurs at the boundary layer and airflow breaks away from the airfoil?
lift is destroyed
Which are NOT parts of a basic hydraulic system?
Reservoir
Pump

Stabilizer
Flow Divider
Stabilizer
What are some characteristics of HIGH clouds?
Normally just frozen ice crystals; usually not a threat to aviation
What happens as AoA is increased?
Lift increases until critical angle of attack.
Name each of the pitot-static instruments AND their source(s).
Airspeed Indicator - pitot & static
Altimeter - static
VSI - static
Describe weather associated with a warm front.
Light to moderate precipitation
Stratiform clouds with poorer visibility
Rain showers
Can a wing stall if it is going faster than its stall speed?
yes!
Describe each kind of static and dynamic stability. Draw pictures.
Jessi will check
With respect to weight, what happens when an aircraft is in a steeply banked turn while maintaining level flight?
The aircraft will weigh more.
