Flight Controls & Magnetic Compass (Knowledge)
What is the full flap operating range for the airplane
55 to 100 knots
One of the main functions of flaps during approach and landing is to
Increase the angle of descent without increasing the airspeed
The magnetic compass
Is self powered
On a turn from a northerly heading the compass will
Lag behind the airplane
How should flight controls be held while taxiing a tailwheel airplane with a left quartering tailwind
Left aileron down, elevator down
In northern hemisphere, magnetic compass will normally indicate initially a turn toward east if
Left turn is entered from a north heading
To minimize the side loads placed on the landing gear during touchdown, the pilot should keep
Longitudinal axis of the aircraft parallel to the direction of its motion
Extending the flaps
Lowers the stalling speed
The only north seeking instrument in a typical training airplane is
Magnetic Compass
Deviation in a magnetic compass is caused by the
Magnetic fields within the aircraft distorting the lines of magnetic force
Angular difference between true north and magnetic north is
Magnetic variation
What is an important airspeed limitation that is not color coded on airspeed indicators
Maneuvering speed
Most U.S. built aircraft engine rotate the propeller clockwise, as viewed from the pilots seat, when the aircrafts wheels are on the ground during the takeoff roll, torque reaction causes
More weight to be placed on the left main landing gear
A turn coordinator provides an indication of the
Movement of the aircraft about the yaw and roll axes
What is the maximum structural cruising speed
165 knots
What is the caution range of the airplane
165 to 208 knots
The pitot-static system is a source of pressure for the
1. Altimeter 2. Vertical-speed indicator 3. Airspeed indicator
What is the maximum flaps extended speed
100 knots
The maximum speed at which the airplane can be operated in smooth air is
208 knots
ANDS
Accelerate North Decelerate South
What should be the first action after starting an aircraft engine
Adjust for proper RPM and check for desired indications on the engine gauges
When taxiing with strong quartering tailwinds, which aileron positions should be used?
Aileron down on the side from which wind is blowing
Which aileron position should a pilot normally use when taxiing in strong quartering headwinds
Aileron up on the side form which the wind is blowing
In the northern hemisphere, the magnetic compass will normally indicate a turn toward the south when
Aircraft is decelerated while on a west heading
The pitot system provides impact pressure for which instrument
Airspeed indicator
Which instrument will become inoperative if the pitot tube becomes clogged?
Airspeed indicator
In northern hemisphere, magnetic compass will normally indicate a turn toward the north if
An aircraft is accelerated while on a east or west heading
Applying carburetor heat will
Enrich the fuel/air mixture
If you land without the use of flaps, approach will be
Faster and shallower
Under what condition is pressure altitude and density altitude the same value
At standard temperature
The possibility of carburetor icing exists even when the ambient air temperature is as
High as 70 degrees and the relative humidity is high
Excessively high engine temperatures will
Cause loss of power, excessive oil consumption, and possible permanent internal engine damage
Deviation error of the magnetic compass is caused by
Certain metals and electrical systems within the aircraft
For internal cooling, air cooled engines are especially dependent on
Circulation of lubricating oil
On a turn from the south
Compass exaggerates the rate of turn
What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a south heading in the northern hemisphere
Compass will indicate a turn to the right, but at a faster rate than is actually occurring.
On a northerly heading, if a right turn is made toward the east
Compass will initially indicate a turn in the opposite direction or west
At the beginning of a turn from a northerly heading
Compass will show a turn in the opposite direction
Purpose of rudder on an airplane
Control yaw
In Northern hemisphere, if an aircraft is accelerated/decelerated the magnetic compass will normally indicate
Correctly when on a north/south heading
Generally speaking, the use of carburetor heat tends to
Decrease engine performance
What is one procedure to aid in cooling an engine that is overheating
Enrich the fuel mixture
Magnetic compass inherently seeks
North
No acceleration or deceleration error on a heading of
North or south
During flight, when are the indications of a magnetic compass accurate
Only in straight and level unaccelerated flight
To receive accurate indications during flight from a heading indicator, the instrument must be
Periodically realigned with the magnetic compass as the gyro precesses
Elevator/Stabilator
Pitch, lateral, longitudinal
Density Altitude
Pressure altitude corrected for nonstandard temperature
How do variations in temperature affect the altimeter
Pressure levels are raised on warm days and the indicated altitude is lower than true altitude
Which wind condition would be most critical when taxiing a nose wheel equipped high wing airplane
Quartering tailwind
Indicated Altitude
Read directly from the altimeter when set to the current barometric pressure setting.
What action can a pilot take to aid in cooling an engine that is overheating during a climb
Reduce rate of climb and increase airspeed
Aileron
Roll, longitudinal, lateral
A positive indication on an ammeter
Shows the rate of charge on the battery
Which condition is most favorable to the development of carburetor icing?
Temperature between 20 degrees and 70 degrees and high humidity
If the pitot tube and outside static vents become clogged, which instruments would be affected?
The altimeter, airspeed indicator, and vertical speed indicator
What change occurs in the fuel/air mixture when carburetor heat is applied
The fuel/air mixture becomes richer
An abnormally high engine oil temperature indication may be caused by
The oil level being too low
True Altitude
The vertical distance of the airplane above sea level; the actual altitude. It is often expressed as feet above mean sea level (MSL); airport, terrain and obstacle elevations on aeronautical charts are true altitudes
One purpose of wing flaps
To enable the pilot to make steeper approaches to a landing without increasing airspeed
When taxiing a tricycle gear equipped airplane with a left quartering tailwind
Use down aileron on the left hand wing and down elevator
When taxiing a tricycle gear equipped airplane into a left quartering headwing
Use up aileron on the left hand wing and neutral elevator
When taxiing a tailwheel airplane into a right quartering headwind
Use up aileron on the right hand wing and up elevator
Pressure Altitude
Vertical distance above the standard datum plane
Absolute Altitude
Vertical distance of an airplane above the terrain, or above ground level
Fuel/air ratio is the ratio between the
Weight of fuel and weight of air entering the cylinder
Under which condition is indicated altitude the same as true altitude
When at sea level under standard conditions
Under which condition will pressure altitude be equal to true altitude
When standard atmosphere conditions exist
Rudder
Yaw, vertical, directional
