Stage 1 Flashcards
What are the characteristics of a monocoque airplane structure?
Almost all structural loads are carried by the outer skin of the airplane.
Which control surfaces are usually located on the empennage?
Rudder elevator stabilator
What condition must be present for carburetor ice to form?
High relative humidity
A power loss occurs when you apply carburetor heat because
less dense air is entering the engine.
Detonation can be described as
fuel in the cylinders exploding instead of burning smoothly.
If the engine magneto switch is turned to the ‘OFF’ position but the engine continues to run the probable cause is
a broken magneto ground wire.
Excessive cylinder head and engine oil temperatures can be caused by
using a lower-than-normal fuel grade.
The three pressure instruments connected to the pitot-static system are the
airspeed indicator altimeter and vertical speed indicator.
According to the markings on the accompanying airspeed indicator what is the maximum speed with flaps fully extended?
85 knots (white arc)
Assume that you land at an airport with the altimeter set to 29.92 instead of the current setting of 30.00. What will the altimeter read if the field elevation is 2 000 feet MSL?
2 080 feet MSL (10 feet per .01 in. Hg.)
The turn coordinator provides a direct indication of aircraft
rate of turn.
The attitude indicator reflects the airplane’s movement about the
longitudinal and lateral axes.
How often should you check the heading indicator and align it with the magnetic compass?
Every 15 minutes
After departing runway 36 you make a left turn to a heading of 180º. If the magnetic compass initially indicates a turn in the opposite direction you should know that this reaction is
normal for all magnetic compasses under similar conditions. (magnetic dip)
What two conditions normally cause an increase in lift?
Increased angle of attack and increased speed
What causes the separation of air over the wing during a stall?
The angle formed by the wing chord line and the relative wind is excessive regardless of airspeed or altitude.
How are the lift and drag components of the wing affected when you lower the flaps?
Both lift and drag increase
Wingtip vortices contribute to the production of
induced drag.
What are the control characteristics of an aircraft with the CG forward of limits?
Very stable pitch inadequate elevator control for landing longer takeoff run and greater nose-over tendency.
Dihedral is used to stabilize the airplane about the
longitudinal axis.
