Q

If you press the left pedal, what impact does this have on the rudder?

A

The rudder will extend to the left which will cause the nose of the plane to be shoved to the left by the air flow.

33
What is the difference between Steerable and Castering nosewheels?
Steerable nosewheels are linked to the rudders by cables and rods and castering are not. Castering nosewheels can still be controlled by rudders but breaks must be used to, particularly in sharp turns.
34
When not classifying landing gear by the placement of the wheel, what are the two kinds of landing gear?
Fixed Gear | Retractable Gear
35
What are the benefits of fixed gear landing gear?
Simplicity and low cost
36
What is the benefit of retractable landing gear?
More streamlined aerodynamics, but the high cost typically limits it to high performance aircraft.
37
What kind of landing gear is best for rough unpaved landing strips?
Tail wheel planes with conventional landing gear.
38
What is a plane that can also serve as a boat called?
An Amphibian
39
How is a seaplane different from an amphibian?
The seaplane has twin floats for landing on water, but an amphibian can actually act as a boat in the water as well.
40
What are struts for?
They attach the wheels to the planes and trasmit the shock of landing to the plane at an acceptable rate.
41
What is an oleo strut?
The most popular strut, it uses a piston enclosed in a cylinder with oil and compressed air to absorb shock.
42
What kind of brakes do training planes usually have?
Disk Brakes
43
What is differential braking?
Applying more preasure to one set of brakes than to the other.
44
What do you use differential braking for?
To help steer the plane on the ground.
45
What are the two parts of the powerplant?
Engine | Propeller
46
What are the three things accessories mounted to the engine do?
Generate Electrical power Create a vacuum source for flight instraments Heat the cockpit
47
What separates the engine compartment and the cockpit?
The firewall
48
What does the cowling do?
Encloses the engine, and cools it by ducting air around the cylinders.
49
What does the propeller do?
Receives power from the engine and converts it into thrust which yields forward motion.
50
What does POH stand for?
Pilot Operating Handbook
51
What does AFM stand for?
Airplane Flight Manual (Specific to an airplanes model and required for all planes after 1979)

What is a static port for?
Measures air pressure not relative to speed.
77
Where is the static port located?
Flush mounted on the side of the fuselage where the air is relatively undisturbed
78

By comparing the speed of static pressure with the speed of ram air pressure.
79
What do the various colors on the airspeed indicator mean?
White Arch=Flap operating ranges Green Arc is normal operations Yellow Arc is the caution range. Only fly in this range in smooth air and do so with caution. Red Line marks the never exceed speed
80
What are V-Speeds?
Speeds at the boundaries of a colored arc on the airspeed indicator which indicate airspeed limitations.
81
What is the Vs0 speed?
It's at the lower limit of the white arc. It's the stall speed when in landing configuration.
82
What is the Vs1 speed?
It's at the lower limit of the green arch. It's the stall speed when in regular flight configuration.
83
What is the Vfe speed?
It's at the upper limit of the white arc. It's the maximum speed for flaps extended.
84
Whats the Vno speed?
It's at the upper limit of the green arc. It's maximum cruise speed. Don't exceed except in smooth air.
85
What is the Vne speed?
The red line. Never exceed. Operating above this speed may cause structural failure.
86
What is the VA speed?
Maximum manuevering speed. You find this in the POH as its dependant on the load being carried.
87
If you have landing gear, what V-speeds do you need to pay attention to?
VLE-maximum speed for landing gear being extended | VLO-maximum speed for raising or lowering landing gear
88
What does IAS stand for?
Indicated Airspeed
89
What does Indicated Airspeed mean?
It's the reading you get from the airspeed indicator. It's set for sea level and doesn't adjust when you climb. It's also uncorrected for installation and instrament errors.
90
What is CAS?
Calibrated Airspeed
91
What does Calibrated Airspeed mean?
It's Indicated airspeed adjusted for installation and instrament errors by consulting the tables in the POH.
92
What does TAS stand for?
True Airspeed
93
What does True Airspeed mean?
The speed of your plane through the air. It's calibrated airspeed corrected for increased altitude and non-standard temperature.
94
What does GS stand for?
Groundspeed
95
How is groundspeed calculated?
It's True Airspeed adjusted for wind.
