Which aircraft construction material combines two or more materials together to make a
structure that is much stronger than the individual components?
Composite
In addition to wire-braced wings, what identifies open truss structure?
Clearly visible struts
Which fuselage design cannot tolerate dents or deformations of the surface?
Monocoque
Which wing design contains no external bracing?
Cantilever
A conventional empennage always contains what two components?
Vertical stabilizer, or fin, and a horizontal stabilizer
What small hinged device on an airplane is used to help minimize the pilot's workload?
Trim tab
Aircraft brakes are located on which wheels?
Main wheels
Most general aviation airplane propellers have how many blades?
2 or 3
Where are the required operating limits and weight and balance records for a particular
aircraft found?
Pilots Operating Handbook (POH)
What is the other accepted name for the pilot's operating handbook (POH)?
FAA Approved Flight Manuel
,Using the ISA standards for altitude change, if an aircraft is at 4,000 feet and 10 degrees C,
what will the temperature be if the aircraft increases to 10,000 feet?
-2 degrees C
What is the pitot-static system used for?
To determine speed, altitude, and altitude trend
The pitot-static system generally consists of what two components?
The pitot tube and pitot-static instruments
Vso
Airspeed indicator: Lowest limit of the white arc, the stall speed or the minimum steady flight
speed in the landing configuration.
Vs1
Airspeed: Lowest limit of the green arc, the stall speed or minimum steady flight speed obtained
in a specific configuration
Vfe
Maximum speed with the flaps extended. Upper limit of the green arch
Vno
Upper limit of the green arc, the maximum structural cruising speed
Va
Design maneuvering speed. Listed in POH. Speed you can use full control movement and not
cause structural damage to the aircraft. It changes with aircraft weight. It's greater when aircraft
is heavy and lower when the load is light.
Vlo and Vle
Max landing gear operating airspeed and maximum landing gear extended airspeed
Indicated airspeed (IAS)
On airspeed indicator. It's calibrated for sea level conditions.
Doesn't reflect variation in air density.
Importance performance airspeeds are always the same indicated airspeed, regardless of
altitude.
Calibrated airspeed (CAS)
, Indicated airspeed corrected for installation error and instrument error.
Determine by looking at chart in the POH.
True airspeed (TAS)
Actual speed through the air. Calibrated airspeed corrected for density changes due to altitude
and temperature.
Use flight computer to determine.
Groundspeed
Actual speed over the ground.
TAS and Groundspeed are equal in a no wind situation.
- A headwind decreases groundspeed
- A tailwind increases groundspeed
- It is not on the airspeed indicator
Vn
Maximum structural cruising speed
What is the altimeter?
It measures the aircraft's altitude and is part of the pitot-static system.
- Indications are based on the mean sea level (MSL)
-Change the Kollsman window to compensation for changes in local pressure.
-Indicated altitude changes about 1,000 feet for every inch of change in the setting.
-Altimeter settings are accurate only in the vicinity of the reporting station.
What do the dials on the altimeter mean?
The longer of the two needles indicates multiples of 100 feet.
The shorter of the two needles indicates multiples of 1,000 feet
The pointer indicates multiples of 10,000 feet
- A crosshatched area appears at altitudes below 10,000 feet MSL
What is the Kollsman window?
The altimeter setting window. Turn the know to a higher setting increases the indicated altitude.
Changes 1,000 feet for every inch of change in the setting.
What are the 6 main types of altitude?
Indicated altitude
Pressure altitude
Density altitude
