Under Pressure
These instruments are driven by the Pitot-Static System.
This is the primary source of lift for the aircraft.
What is Bernoulli's Principle?
This is the only self contained direction seeking instrument on the aircraft.
What is the magnetic compass?
Assuming normal operation, this device provides the necessary power to all electrical devices during ground and flight operations.
What is the alternator/generator?
This type of controllable pitch propeller can be set to any setting between its minimum and maximum settings, allowing for a wide variety of performance options.
What is a constant-speed propeller?
This device measures ambient pressure and sends information to all three pressure based instruements.
What is the Static Port?
This form of drag increases exponentially as airspeed increases.
What is Parasite Drag?
The difference between true north and magnetic north.
What is magnetic variation?
The alternator/generator relies on this to be turning for its operation.
This feature of a propeller blade allows it to have a relatively similar angle of attack along the length of the blade.
What is the twisting of the blade?
The airspeed that allows for the most altitude gain over a given distance, or the best rate of climb.
What is Vy?
An aircraft will always stall when it exceeds this aerodynamic feature.
What is the critical angle of attack?
This instrument must be reset using the magnetic compass every 15 minutes.
What is the heading indicator?
This gauge measures the health of the electrical system by showing any charge to or discharge from the battery.
This is the most desired combination of blade pitch and RPM setting for takeoff in an aircraft with a constant speed propeller.
What is low pitch, high RPM?
Pressure altitude corrected for nonstandard temperature.
What is density altitude?
These devices on the airplane allow for a steeper approach to landing without an associated increase in airspeed.
The disruption of the magnetic compass due to the magnetic fields generated by electrical equipment within the aircraft itself.
What is magnetic deviation?
These serve as a common connection point where all the electrical devices can receive the necessary power from the battery or alternator.
What are bus bars?
Power output in an airplane with a constant-speed propeller is measured by this instrument.
What is the manifold pressure gauge?
This airspeed is the indicated airspeed corrected for installation and position errors.
What is calibrated airspeed?
When flying in ground effect, the ground interferes with the formation of these aerodynamic features, allowing a decrease in drag and an increase in performance.
The fluid in which the magnetic compass floats, allowing for smooth movement of the compass.
What is kerosene?
This switch protects sensitive electrical equipment from the power surge that happens with the starting of the engine.
What is the avionics master switch?
This feature of a propeller adds to the left-turning tendencies of the aircraft.
What is P-Factor?
