Which of the following is true concerning flaps? A. Flaps are attached to the leading edge of the wing and are used to increase wing lift. B. Flaps allow an increase in the angle of descent without increasing airspeed.
What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight? - ✔✔Lift equals weight. Thrust equals drag. Which statement relates to Bernoulli's principle? - ✔✔Air traveling faster over the curve upper surface of an airfoil causes lower pressure on the top surface.

How will frost on the wings of an airplane affect takeoff performance? - ✔✔Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability. Why is frost considered hazardous to flight? - ✔✔Frost spoils the smooth flow of air over the wings, thereby decreasing lifting capability.
What force makes an airplane turn? - ✔✔The horizontal component of lift. An airplane said to be inherently stable will... - ✔✔require less effort to control. What determines the longitudinal stability of an airplane? - ✔✔The location of the CG with respect to the center of lift. Changes in the center of pressure of a wing affect the aircraft's... - ✔✔Aerodynamic balance and controllability. An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be... - ✔✔Difficulty in recovering from a stalled condition.
What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted? - ✔✔The downwash on the elevators from the propeller slipstream is reduced and the elevator effectiveness is reduced Loading an airplane to the most aft CG will cause the airplane to be... - ✔✔Less stable at all speeds. In what flight condition is torque effect the greatest in a single-engine airplane? - ✔✔Low airspeed, high power, high angle of attack. The left turning tendency of an airplane caused by P-factor is the result of the... - ✔✔Propeller blade descending on the right, producing more thrust than the ascending blade on the left. When does P-factor cause the airplane to yaw to the left? - ✔✔When at high angles of attack.
Deviation in a magnetic compass is caused by the... - ✔✔Magnetic fields within the aircraft distorting the lines of magnetic force. In the Northern Hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will normally indicate... - ✔✔Correctly when on a north or south heading. In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the west if... - ✔✔A right turn is entered from a north heading. In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward the south when... - ✔✔The aircraft is decelerated while on a west heading.
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the east if... - ✔✔A left turn is entered from a north heading. 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?
- ✔✔The compass will indicate a turn to the right, but at a faster rate than is actually occurring. The pitot systems provides impact pressure for what instrument? - ✔✔Airspeed indicator. Which instrument will become inoperative if the pitot tube becomes clogged? - ✔✔Airspeed. If the pitot tube and outside static vents become clogged, which instruments would be affected? - ✔✔The altimeter, airspeed indicator, & vertical speed indicator.
What is density altitude? - ✔✔The pressure altitude corrected for nonstandard temperature. Under what conditions is pressure altitude and density altitude the same value? - ✔✔At standard temperature. Under what condition is indicated altitude the same as true altitude? - ✔✔When at sea level under standard conditions. Under what condition will pressure altitude be equal to true altitude? - ✔✔When standard atmospheric conditions exist. What is pressure altitude? - ✔✔The altitude indicated when the barometric pressure scale is set to 29.92.
Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates... - ✔✔True altitude at field elevation. If it is necessary to set the altimeter from 29.15 to 29.85 what change occurs? - ✔✔700 foot increase in indicated altitude. (The altimeter-indicated altitude moves in the same direction as the altimeter setting and changes about 1,000 ft. for every change of 1" Hg.) If a pilot changes the altimeter setting from 30.11 to 29.96 what is the approximate change in indication? - ✔✔Altimeter will indicate 150 feet lower. If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate... - ✔✔Lower than the actual altitude above sea level.
How do variations in temperature affect the altimeter? - ✔✔Pressure levels are raised on warm days and the indicated altitude is lower than the true altitude. What is a benefit of flying with a glass cockpit? - ✔✔Situational awareness is increased. What steps must be taken when flying with glass cockpits to ensure safe flight? - ✔✔Regularly scan both inside and outside, use all appropriate checklist, and cross-check with other forms of information. An abnormally high engine oil temperature indication may be caused by... - ✔✔The oil level being too low. Excessively high engine temperatures will... - ✔✔Cause loss of power, excessive oil consumption, & possible permanent internal engine damage.
Excessively high engine temperatures, either in the air or on the ground, will... - ✔✔Cause loss of power, excessive oil consumption, & possible permanent internal engine damage. For internal cooling, air cooled engines are especially dependent on... - ✔✔The circulation of lubricating oil. If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with...
- ✔✔too much power and with the mixture set too lean. 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.
If the ignition switch ground wire becomes disconnected, the magneto... - ✔✔May continue to fire. With regard to carburetor ice, float-type carburetor systems in comparison to fuel injection systems are generally considered to be... - ✔✔More susceptible to icing. Which condition is most favorable to the development of carburetor icing? - ✔✔Temperature between 20ºF and 70ºF and high humidity. The possibility of carburetor icing exist even when the ambient air temperature is as... - ✔✔High as 70ºF and the relative humidity is high. If an aircraft is equipped with a fixed-pitch propeller and a float-type carburetor, the first indication of carburetor ice would most likely be... - ✔✔Loss of RPM.
The operating principle of float-type carburetors is based on the... - ✔✔Difference in air pressure at the venturi throat and the air inlet.
