10. Altimeter 1 indicates (Refer to Figure 3: Altimeter)
Answer (C) is correct. (FAA-H-8083-25B Chap 8) The altimeter has three needles. The short needle indicates 10,000-foot intervals, the middle-length needle indicates 1,000-foot intervals, and the long needle indicates 100-foot intervals. In altimeter 1, the shortest needle is on 1, which indicates about 10,000 feet. The middle-length needle indicates half-way between zero and 1, which is 500 feet. This is confirmed by the longest needle on 5, indicating 500 feet, i.e., 10,500 feet.
11 / 28
11. Altimeter 3 indicates (Refer to Figure 3: Altimeter)
Answer (C) is correct. (FAA-H-8083-25B Chap 8) Altimeter 3 indicates 9,500 feet because the shortest needle is near 1 (i.e., about 10,000 feet), the middle needle is between 9 and the 0, indicating between 9,000 and 10,000 feet, and the long needle is on 5, indicating 500 feet.
12 / 28
12. Which altimeter(s) indicate(s) more than 10,000 feet? (Refer to Figure 3: Altimeter)
Answer (C) is correct. (FAA-H-8083-25B Chap 8) Altimeters 1 and 2 indicate over 10,000 feet because 1 indicates 10,500 feet and 2 indicates 14,500 feet. The short needle on 3 points just below 1, i.e., below 10,000 feet.
13 / 28
13. Altimeter 2 indicates (Refer to Figure 3: Altimeter)
Answer (C) is correct. (FAA-H-8083-25B Chap 8) Altimeter 2 indicates 14,500 feet because the shortest needle is between the 1 and the 2, indicating about 15,000 feet; the middle needle is between 4 and 5, indicating 4,500 feet; and the long needle is on 5, indicating 500 feet, i.e., 14,500 feet.
14 / 28
14. Altimeter 3 indicates (Refer to Figure 3: Altimeter)
Answer (C) is correct. (FAA-H-8083-25B Chap 8) The long, thin needle is past the fourth tick mark and just before the 1 (<10,000); the short needle is between the 9 and 0 (representing more than 9 thousands of feet); and the long, wide needle is on the 5 (representing 5 hundreds of feet). Therefore, the altimeter indicates 9,500 feet.
15 / 28
15. Altimeter 1 indicates (Refer to Figure 3: Altimeter)
Answer (A) is correct. (FAA-H-8083-25B Chap 8) The long, thin needle is between 0 and 1 (<10,000); the short needle is between 0 and 1 (<1,000); and the long, wide needle is on 5 (500). Therefore, the altimeter indicates 500 feet.
16 / 28
16. Altimeter 2 indicates (Refer to Figure 3: Altimeter)
Answer (A) is correct. (FAA-H-8083-25B Chap 8) The long, thin needle is to the right of 0, just before the first tick mark (<2,000); the short needle is halfway between the 1 and 2 (representing 1.5 thousands of feet); and the long, wide needle is on the 5 (representing 5 hundreds of feet). Therefore, the altimeter indicates 1,500 feet.
17 / 28
17. Which altimeter(s) indicate(s) more than 9,000 feet? (Refer to Figure 3: Altimeter)
Answer (A) is correct. (FAA-H-8083-25B Chap 8) Altimeter 3 indicates 9,500 feet. Altimeters 1 and 2 both indicate under 9,000 feet.
18 / 28
18. If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs?
Answer (A) is correct. (FAA-H-8083-25B Chap 8) When increasing the altimeter setting from 29.15 to 29.85, the indicated altitude increases by 700 feet. The altimeter-indicated altitude moves in the same direction as the altimeter setting and changes about 1,000 feet for every change of 1" Hg in the altimeter setting.
19 / 28
19. If a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in indication?
Answer (C) is correct. (FAA-H-8083-25B Chap 8) Atmospheric pressure decreases approximately 1" of Hg (mercury) for every 1,000 feet of altitude gained. As an altimeter setting is changed, the change in altitude indication changes the same way (i.e., approximately 1,000 feet for every 1" change in altimeter setting) and in the same direction (i.e., lowering the altimeter setting lowers the altitude reading). Thus, changing from 30.11 to 29.96 is a decrease of .15 in., or 150 feet (.15 × 1,000 feet) lower.
20 / 28
20. A turn coordinator provides an indication of the (Refer to Figure 5: Turn Coordinator)
Answer (B) is correct. (FAA-H-8083-25B Chap 8) There really are no yaw and roll axes; i.e., an airplane yaws about its vertical axis and rolls about its longitudinal axis. However, this is the best answer since the turn coordinator does indicate the roll and yaw movement of the airplane. The movement of the miniature airplane is proportional to the roll rate of the airplane. When the roll rate is reduced to zero (i.e., when the bank is held constant), the instrument provides an indication of the rate of turn.
21 / 28
21. To receive accurate indications during flight from a heading indicator, the instrument must be (Refer to Figure 6: Heading Indicator)
Answer (B) is correct. (FAA-H-8083-25B Chap 8) Due to gyroscopic precession, directional gyros must be periodically realigned with a magnetic compass. Friction is the major cause of its drifting from the correct heading.
22 / 28
22. The proper adjustment to make on the attitude indicator during level flight is to align the (Refer to Figure 7: Attitude Indicator)
Answer (B) is correct. (FAA-H-8083-25B Chap 8) The horizon bar (marked as B) on Fig. 7 represents the true horizon. This bar is fixed to the gyro and remains on a horizontal plane as the airplane is pitched or banked about its lateral or longitudinal axis, indicating the attitude of the airplane relative to the true horizon. An adjustment knob is provided, with which the pilot may move the miniature airplane (marked as C) up or down to align the miniature airplane with the horizontal bar to suit the pilot’s line of vision.
23 / 28
23. How should a pilot determine the direction of bank from an attitude indicator such as the one illustrated? (Refer to Figure 7: Attitude Indicator)
Answer (A) is correct. (FAA-H-8083-25B Chap 8) The direction of bank on the attitude indicator (AI) is indicated by the relationship of the miniature airplane to the deflecting horizon bar. The miniature airplane’s relative position to the horizon indicates its attitude: nose high, nose low, left bank, right bank.
24 / 28
24. Prior to takeoff, the altimeter should be set to which altitude or altimeter setting?
Answer (C) is correct. (14 CFR 91.121) Prior to takeoff, the altimeter should be set to either the local altimeter setting or to the departure airport elevation.
25 / 28
25. If an altimeter setting is not available before flight, to which altitude should the pilot adjust the altimeter?
Answer (C) is correct. (14 CFR 91.121) When the local altimeter setting is not available at takeoff, the pilot should adjust the altimeter to the elevation of the departure area.
26 / 28
26. At what altitude shall the altimeter be set to 29.92 when climbing to cruising flight level?
Answer (A) is correct. (14 CFR 91.121) Pressure altitude is the altitude used for all flights at and above 18,000 feet MSL, i.e., in Class A airspace. When climbing to or above 18,000 feet MSL, one does not use local altimeter settings, but rather 29.92" Hg after reaching 18,000 feet MSL.
