If the RVR is inoperative for the runway in use, except for Category II or Category III, you must
B) convert RVR minimums and use the value as ground visibility.
What point should be used to compute estimated time en route on an IFR flight plan?
C) The point of first intended landing.
On what headings will the magnetic compass read most accurately during a level 360° turn, with a bank of approximately 15°?
B) 90° and 270°
(Refer to figure 91.) What should be the approximate elapsed time from BZN VOR to DBS VORTAC, if the wind is 24 knots from 260° and your intended TAS is 185 knots?
B) 38 minutes.
(Refer to figure 91.) Southbound on V257, you cross over CPN VORTAC at 0950 and over DIVID intersection at 0954. At what time should you arrive at DBS VORTAC?
A) 1043.
(Refer to figure 95.) You are tracking the 170 course to the station. What is your lateral displacement from the desired course on the No. 1 NAV?
C) 5.0 NM.
While in IMC, a pilot often interprets acceleration or deceleration forces as a sensation of
C) climbing or descending.
If a standard-rate turn is maintained, how much time would be required to turn to the left from a heading of 090° to a heading of 300°?
B) 50 seconds.
If a half standard-rate turn is maintained, how long would it take to turn 135°?
B) 90 seconds.
What causes the northerly turning error in a magnetic compass?
C) The pull of the vertical component of the Earth’s magnetic field.
The turn coordinator indicates
A) rate of roll and rate of turn.
If a half standard-rate turn is maintained, how long would it take to turn 360°?
A) 4 minutes.
If a standard-rate turn is maintained, how long would it take to turn 180°?
C) 1 minute.
If a half standard-rate turn is maintained, how much time would be required to turn clockwise from a heading of 090° to a heading of 180°?
C) 1 minute.
If a standard-rate turn is maintained, how much time would be required to turn to the right from a heading of 090° to a heading of 270°?
B) 1 minute.
When an aircraft is accelerated, some attitude indicators will precess and incorrectly indicate a
A) climb.
When an aircraft is decelerated, some attitude indicators will precess and incorrectly indicate a
B) descent.
What indication should be observed on a turn coordinator during a left turn while taxiing?
A) The miniature aircraft will show a turn to the left and the ball moves to the right.
On a taxi check, the magnetic compass should
B) swing freely and indicate known headings.
Which condition during taxi is an indication that an attitude indicator is unreliable?
B) The horizon bar tilts more than 5° while making taxi turns.
Prior to takeoff, the attitude indicator is considered reliable and properly checked when
A) the horizon bar remains in the horizontal position and does not tip more than 5° during taxi.
What pretakeoff check should be made of a vacuum driven heading indicator in preparation for an IFR flight?
C) After 5 minutes, set the indicator to the magnetic heading of the aircraft and check for proper alignment after taxi turns.
What is the correct sequence in which to use the three skills used in instrument flying?
C) Cross-check, instrument interpretation, and aircraft control.
What are the fundamental skills required for attitude instrument flying?
A) Cross-check, Instrument interpretation, and aircraft control.
