Correct! 700-foot increase in indicated altitude. When the knob on the altimeter is rotated, the pressure scale moves simultaneously with the altimeter pointers. The numerical values of pressure indicated in the window increase while the altimeter indicates an increase in altitude; or decrease while the altimeter indicates a decrease in altitude. This is contrary to the reaction on the pointers when air pressure changes, and is based solely on the mechanical makeup of the altimeter. The difference between the two settings is equal to 0.70" Hg (29.85 - 29.15). At the standard pressure lapse rate of 1" Hg = 1,000 feet in altitude, the amount of change equals 700 feet. Question 3 4 / 4 pts Pressure altitude corrected for nonstandard temperature. The elevation of the nearest airport corrected to mean sea level. Correct! The elevation of the departure area. The altimeter should be set to the elevation of the departure airport for airplanes, and the departure area for other aircraft. Question 4 4 / 4 pts horizon bar to the miniature airplane. horizon bar to the level-flight indication. Correct! miniature airplane to the horizon bar. The miniature airplane 'C' is adjusted so that the wings overlap the horizon bar 'B' when the airplane is in straight-and-level cruising flight. Question 5 0 / 4 pts The compass will remain on south for a short time, then gradually catch up to the magnetic heading of the airplane. Correct Answer The compass will indicate a turn to the right, but at a faster rate than is actually occurring. You Answered The compass will initially indicate a turn to the left. If you are on a southerly heading and roll into a standard-rate turn to the right, the compass will immediately indicate a turn toward the west (to the right) because of the northerly turning error. During the first part of the turn, it will show a faster rate of turn than you are actually making. If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs? If an altimeter setting is not available before flight, to which altitude should the pilot adjust the altimeter? (Refer to Figure 7.) The proper adjustment to make on the attitude indicator during level flight is to align the 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 red radial line. Upper limit of the green arc. Upper limit of the white arc. The upper end of the arc is marked by a red radial line which is the never-exceed speed (V(NE)). Question 7 0 / 4 pts You Answered The indicated altitude corrected for nonstandard temperature and pressure. The indicated altitude corrected for position and installation error. Correct Answer The altitude indicated when the barometric pressure scale is set to 29.92. The pressure altitude can be determined by either of two methods: 1. Setting the barometric scale of the altimeter to 29.92 and reading the indicated altitude, or 2. Applying a correction factor to the elevation (true altitude) according to the reported 'altimeter setting.' Question 8 4 / 4 pts Correct! 165 knots. 208 knots. 100 knots. The green arc is the normal operating range. The upper end of the arc (V(NO)) is defined as the 'maximum structural cruising speed.' Question 9 4 / 4 pts The vertical distance of the aircraft above the surface. Correct! The vertical distance of the aircraft above sea level. The height above the standard datum plane. True altitude is height above sea level. Airport terrain and obstacle elevations found on aeronautical charts are true altitudes. Question 10 0 / 4 pts (Refer to Figure 4.) Which marking identifies the never-exceed speed? What is pressure altitude? (Refer to Figure 4.) What is the maximum structural cruising speed? What is true altitude?

You Answered The altimeter, airspeed indicator, and turn-and-slip indicator. The altimeter, attitude indicator, and turn-and-slip indicator. Airspeed, altimeter and vertical speed all receive static input and would indicate inaccurately if the static sources became plugged. Question 11 4 / 4 pts Correct! The vertical distance of the aircraft above the surface. The height above the standard datum plane. The altitude read directly from the altimeter. Absolute altitude is height above the surface. This height may be indicated directly on a radar altimeter. Absolute altitude may be approximately computed from indicated altitude and chart elevation data. Question 12 0 / 4 pts Upper limit of the green arc. Correct Answer Lower limit of the green arc. You Answered Upper limit of the white arc. The green arc is the normal operating range. The lower end of the arc (V(S1)) is the stalling speed in a specified configuration. Question 13 0 / 4 pts Correct Answer Pressure levels are raised on warm days and the indicated altitude is lower than true altitude. Lower temperatures lower the pressure levels and the indicated altitude is lower than true altitude. You Answered Higher temperatures expand the pressure levels and the indicated altitude is higher than true altitude. On a warm day, the expanded air is lighter than on a cold day, and consequently the pressure levels are raised. For example, the pressure level where the altimeter indicates 10,000 feet will be higher on a warm day than under standard conditions. On a cold day the reverse is true. Question 14 0 / 4 pts If the pitot tube and outside static vents become clogged, which instruments would be affected? What is absolute altitude? (Refer to Figure 4.) Which color identifies the power-off stalling speed in a specified configuration? How do variations in temperature affect the altimeter?

Correct Answer lower than the actual altitude above sea level. the actual altitude above sea level. If a flight is made from a high-pressure area to a low-pressure area without adjusting the altimeter, the actual altitude of the airplane will be lower than the indicated altitude, and when flying from a low-pressure area to high-pressure area, the actual altitude of the airplane will be higher than the indicated altitude. Question 15 4 / 4 pts As long as the airspeed is constant. During turns if the bank does not exceed 18°. Correct! Only in straight-and-level unaccelerated flight. The magnetic compass should be read only when the aircraft is flying straight-and-level at a constant speed. This will help reduce errors to the minimum. Question 16 4 / 4 pts Vertical speed. Correct! Airspeed. Altimeter. The pitot tube provides input for the airspeed indicator only. Question 17 4 / 4 pts 1, 2, and 3. 1 only. Correct! 1 and 2 only. The shortest hand (10,000 foot) in #1 is between 1 and 2, indicating 10,000 feet plus. The shortest hand in #2 also indicates 10,000 feet plus. The shortest hand in #3 indicates less than 10,000 feet. Question 18 4 / 4 pts 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 During flight, when are the indications of a magnetic compass accurate? Which instrument will become inoperative if the pitot tube becomes clogged? (Refer to Figure 3.) Which altimeter(s) indicate(s) more than 10,000 feet?

When at sea level under standard conditions. If the altimeter has no mechanical error. When at 18,000 feet MSL with the altimeter set at 29.92. On a standard day (29.92" Hg and +15°C) at sea level, pressure altitude, indicated altitude, and density altitude are all equal. Any variation from standard temperature or pressure will have an effect on the altimeter. Question 19 0 / 4 pts never-exceed speed. You Answered normal operating range. Correct Answer maximum structural cruising speed. V(NO) is the maximum calibrated airspeed for normal operation, or the maximum structural cruising speed. Question 20 0 / 4 pts You Answered calibrated altitude at field elevation. Correct Answer true altitude at field elevation. absolute altitude at field elevation. The local altimeter setting corrects for the difference between existing pressure and standard atmospheric pressure. Whether local pressure is higher or lower than standard, it will indicate true altitude (MSL) at ground level, when the aircraft altimeter is set to the local altimeter setting (assuming no setting scale error). Question 21 0 / 4 pts Correct Answer magnetic variation. You Answered magnetic deviation. compass acceleration error. The angular difference between magnetic north, the reference for the magnetic compass, and true north is variation. Question 22 0 / 4 pts Under what condition is indicated altitude the same as true altitude? V(NO) is defined as the Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates The angular difference between true north and magnetic north is

When the altimeter has no installation error. Correct Answer At standard temperature. When conditions are standard, pressure altitude and density altitude are the same. Question 23 4 / 4 pts Correct! Airspeed, altimeter, and vertical speed. Altimeter only. Airspeed only. Airspeed, altimeter and vertical speed all receive static input and would indicate inaccurately if the static sources became plugged. Question 24 0 / 4 pts You Answered the difference in location of true north and magnetic north. a northerly turning error. Correct Answer certain metals and electrical systems within the aircraft. Magnetic disturbances from magnetic fields produced by metals and electrical accessories in an aircraft disturb the compass card and produce an additional error which is referred to as deviation. Question 25 4 / 4 pts Correct! movement of the aircraft about the yaw and roll axis. attitude of the aircraft with reference to the longitudinal axis. angle of bank up to but not exceeding 30°. The movement of the miniature airplane on the instrument is proportional to the roll rate of the airplane. When the roll rate is reduced to zero, i.e., the bank is held constant, the instrument provides an indication of the rate of turn. This design features a realignment of the gyro in such a manner that it senses airplane movement about the yaw and roll axis. Quiz Score: 56 out of 100 Under what condition is pressure altitude and density altitude the same value? Which instrument(s) will become inoperative if the static vents become clogged? Deviation error of the magnetic compass is caused by (Refer to Figure 5.) A turn coordinator provides an indication of the
