IRA Test Questions and Answers (IFR &
Navigation)
If the RVR is inoperative for the runway in use, except for Category II or Category III, you must - Answer-
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? - Answer-the
point of first intended landing.
On what headings will the magnetic compass read most accurately during a level 360 degree turn, with a
bank of approximately 15 degrees? - Answer-90 degrees and 270 degrees
While in IMC, a pilot often interprets acceleration or deceleration forces as a sensation of - Answer-
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 300 - Answer-50 seconds
if a half standard rate turn is maintained, how long would it take to turn 135 degrees? - Answer-90
seconds
what causes the northerly turning error in a magnetic compass - Answer-the pull of the vertical
component of the earths magnetic field
,the turn coordinator indicates - Answer-rate of roll and rate of turn
if a half standard rate turn is maintained, how long would it take to turn 360 degrees? - Answer-4
minutes
if a standard rate turn is maintained, how long would it take to turn 180 degrees? - Answer-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? - Answer-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 270? - Answer-1 minute
when an aircraft is accelerated, some attitude indicators will precess and incorrectly indicate a -
Answer-climb
when an aircraft is decelerated, some attitude indicators will precess and incorrectly indicate a -
Answer-descent
what indication should be observed on a turn coordinator during a left turn while taxiing? - Answer-the
miniature aircraft will show a turn to the left and the ball moves to the right
on the taxi check, the magnetic compass should - Answer-swing freely and indicate known headings
which condition during taxi is an indication that an attitude indicator is unreliable - Answer-the horizon
bar tilts more than 5 degrees while making taxi turns
, prior to takeoff, the attitude indicator is considered reliable and properly checked when - Answer-the
horizon bar remains in the horizontal position and does not tip more than 5 degrees during taxi
what pretakeoff check should be made of a vacuum driven heading indicator in preparation for an IFR
flight - Answer-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? - Answer-cross
check, instrument interpretation, and aircraft control
what are the fundamental skills required for attitude instrument flying> - Answer-cross check,
instrument interpretation and aircraft control
what is the third fundamental skill in attitude instrument flying? - Answer-aircraft control
what is the first fundamental skill in attitude instrument flying? - Answer-instrument cross-check
while taxiing to the runway for an IFR flight, you notice that your VSI indicates a 75 feet per minute
climb. In this case, you - Answer-may take off IFR and use 75 feet per minute climb as your new level
flight indication
as a rule of thumb, altitude corrections of less than 100 feet should be corrected by using a - Answer-
half bar width on the attitude indicator
for maintaining straight and level flight, which instrument displays a constant indication of altitude? -
Answer-altimeter
the glide slope and localizer are centered, but the airspeed is too fast. which should be adjusted initially?
- Answer-power only
