(U) -Undershoot
(N) - North
(O) - Overshoot
(S) - South
What does the acronym ANDS stand for?
(A) - Accelerate
(N) - North
(D) - Decelerate
(S) - South
Absolute Altitude
Altitude above the surface.
True Altitude
Altitude above mean sea level.
Density Altitude
Pressure altitude corrected for non standard temperature.
Pressure Altitude
The airplanes height above standard (29.92)
Indicated Altitude
Read Directly off the altimeter.
How is engine operation controlled on an engine equipped with a constant speed propeller?
The throttle controls power output as registered on the manifold pressure gauge and the prop control regulates RPM.
If the ignition switch ground wire becomes disconnected from the magneto, the engine?
May continue to fire.
With regard to carbice, float type carburetor systems, in comparison to fuel injection systems, are considered to be?
More susceptible to icing.
What temperatures can carburetor icing occur?
Between 20F and 70F.
What is the first sign that carburetor icing is occurring?
A decrease in RPM’s and than engine roughness.
What does the use of carb heat do?
The use of carb heat causes a decrease in performance.
__________ occurs when the fuel mixture ignites instantaneously instead of burning progressively and evenly.
Detonation
The uncontrolled firing of a fuel charge in advanced of the normal ignition.
Pre-Ignition
Deviation in a magnetic compass is caused by?
Magnetic field within the aircraft distorting the magnetic force.
PITOT static system
Airspeed Indicator
Vertical Speed Indicator
Altimeter
The Airspeed Indicator Red Arch tells you
Never Exceed
The Airspeed Indicator Yellow ARC tells you the
range which it’s safe to operate in smooth air, or it’s also known as your caution range.
The Airspeed Indicator Green Arc is where
the majority of your operations happen.
The Airspeed Indicator Green Arc lower limits are
where we get our stall speeds
VSO
this is our stall speed in the lower configuration. Our landing gear is out.
VSI
the take off configuration and our landing gear is in.
The Airspeed Indicator white arc is
the flap operating range.
VFE
to extend the flaps fully.
Cold air typically brings
lower pressure
The altimeter changes roughly
1000ft per 1”
Gyroscopic Instruments
Periodically realign with the magnetic compass as the gyro precesses.
Is situation awareness increased or decreased in a glass cockpit?
increased
What does a glass cockpit allow you to do more of?
to look outside and fly the airplane.
The throttle controls power output as registered on the manifold pressure gauge and the prop control regardless of RPM.
What is a constant speed propeller?
What is a constant speed propeller?
Allows pilot to choose the blade angle
What keeps the manifold pressure lower than RPM?
Constant Speed Propeller
In the air of a constant speed propeller
Throttle = manifold pressure Prop = RPM (tachometer)
If the engine switch ground wire becomes disconnected from the magneto, the engine?
May continue to fire.
With regard to carb ice, float type carburetor systems, in comparison to fuel injection systems, are considered to be?
More susceptible to icing.
Carburetor icing can occur between what temperatures? (F)
20F-70F
What is the first sign that carburetor icing is occuring?
The first sign of carb ice is a decrease in RPM.
If you use carb heat to stop carburetor icing what effect does that cause?
Use of carb heat causes a decrease in performance.
When does detonation occur?
Detonation occurs when the fuel mixture ignites instantaneously instead of burning progressively and evenly.
What does pre-ignition occur?
Pre-Ignition is the uncontrolled firing of a fuel charge in advanced of the normal ignition.
Applying carburetor heat will
enrich the fuel/air mixture.
A turn coordinator provides an indication of the
A turn coordinator provides an indication of the
A positive indication on an ammeter
shows the rate of charge on the battery.
The operating principle of float-type carburetors is based on the
difference in air pressure at the venturi throat and the air inlet.
The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as
pre-ignition.
