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
