IFR and Navigation Flashcards
(430 cards)
If a pilot elects to proceed to the selected alternate, the landing minimums used at that airport should be the
minimums specified for the approach procedure selected
If the RVR is inoperative for the runway in use, you must
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?
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 degree?
90 and 270 degree
(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 degree and your intended TAS is 185 knots? (VAR 17 degree E)
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?
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?
5.0 NM
While in IMC, a pilot often interprets acceleration or deceleration forces as a sensation of
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 degree to a heading of 300 degree?
50 seconds
If a half standard rate turn is maintained, how long would it take to turn 135 degree?
90 seconds
What causes the northerly turning error in a magnetic compass?
The pull of the vertical component of the Earth’s magnetic field
The miniature airplane on the turn coordinator will indicate
rate of roll and rate of turn
If a half standard rate turn is maintained, how long would it take to turn 360 degree?
4 minutes
If a standard rate turn is maintained, how long would it take to turn 180 degree?
1 minute
If a half standard rate turn is maintained, how much time would be required to turn clockwise from a heading of 090 degree to heading of 180 degree?
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 degree to a heading of 270 degree?
1 minute
When an aircraft is accelerated, some attitude indicators will precess and incorrectly indicate a
climb
When an aircraft is decelerated, some attitude indicators will precess and incorrectly indicate a
descent
What indication should be observed on a turn coordinator during a left turn while taxiing?
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
swing freely and indicate known headings
Which condition during taxi is an indication that an attitude indicator is unreliable?
The horizon bar tilts more than 5 degree while making taxi turns
What pretakeoff check should be made of the attitude indicator in preparation for an IFR flight?
The horizon bar should remain horizontal and not tilt more than 5 degrees during taxi
What pretakeoff check should be made of vacuum driven heading indicator in preparation for an IFR flight?
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?
cross check, instrument interpretation, and aircraft control
