VOR tuned to a VOT should have the CDI centered and the bearing pointer reading 0 degrees with a ____ indication or 180 degrees with a ____ indication. The allowable tolerance is +/- ____ degrees
FROM; TO; +/- 4 degrees
Designated ground checkpoint for VOR: Should read within ____ degrees of the specified course TO or FROm the VOR.
4 degrees
DME check should be within ____ mile(s) or ____% of the total distance (whichever is greater).
1/2 mile or 3%
Airborne checkpoints for VOR consist of certified radials that should be received over specific points or landmarks while airborne in the immediate vicinity of an airport. Must be +/- ____ degrees of the specified radial.
+/- 6 degrees
Dual VOR check must be within ____ degrees of each other
4 degrees
Localizer transmitter normally sits at the ____ end of the runway, specifically about ____ feet beyond the ____ end of the ILS runway, so that it transmits its course signal along the extended runway centerline.
departure end; 1,000 feet; departure end
Glideslope transmitter normally sits about ____ feet from the runway threshold so the TCH of a 3 degree glideslope is between 30-50 feet.
1,000 feet
Localizer width may vary between ____ and ____ degrees.
3 and 6 degrees
Localizer width produces a signal +/- ____ feet either side of centerline at the threshold
350 feet
A localizer is approximately ____ times more sensitive than a VOR signal, therefore, a full scale deflection means you are ____-____ degrees off course.
4 times; 1.5-3 degrees
Localizer may be offset up to ____ degrees, if it exceeds ____ degrees offset then it will be published as an ____ approach.
3 degrees; 3 degrees; LDA
ILS critical area: ATC will not authorize aircraft or vehicles to operate inside the ILS critical area when an aircraft is between the ILS FAF and the airport when the weather is below ____ ft ceiling and/or
800 foot; <2SM vis
The glideslope of an ILS has a usable range of ____ NM
10 NM
ATC is required to provide vector headings to within ____ degrees of the localizer course, at least ____ NM from the glideslope intercept point, and at an altitude ____ glideslope.
30 degrees; 2 NM; below
The localizer course may be flown outside of the ____ NM flight check distance if the instrument procedure depicts a greater distance or radar services are provided. If the controller clears you to intercept a localizer course, regardless of the distance from the antenna, radar service is being provided and you are expected to intercept the localizer
18 NM
Except during high crosswind situations, an accepted technique is to limit heading corrections to within ____ degrees of the inbound course
5 degrees
Should a minor deviation from the GS occur on an ILS, an accepted technique is to make small coordinated pitch and power changes that result in a VVI change of less than ____ to ____ FPM, which equates to ~____-____ degrees of pitch change
200 to 300 FPM; 1-2 degrees
(T/F) If the MA is initiated at the DH, obstacle clearance takes into account the momentary dip below DH during the go-around maneuver to accommodate for the downward vector an aircraft has when flying a constant rate descent.
True
If the course warning flag is displayed during the final approach, ____.
Initiate a MA procedure.
If the glideslope warning is displayed, the approach may be flown no lower than the published ____ or, if not publushed, no lower than the ____ for that aircraft category.
localizer-only altitude; circling minimum altitude
During localizer back course approaches, the CDI is more sensitive because ____.
The localizer antannae is located at the approach end of the runway compared to the departure end of the runway with a normal localizer approach
