TIME CHECK: Another use for VOR is to take a time check, which informs the pilot of the time remaining to fly to a station. For example, while inbound to the station on the 022° radial (See VOR Time Check figure, on the right), the pilot wishes to estimate the time to the station. The pilot elects to use the 030° radial to begin the time check, and turns the aircraft to a heading of 120°, which is at right angles to the 030° radial. The OBS is turned to 030° and as the needle centers, the pilot notes the time. Immediately afterward, the pilot rotates the OBS to 040°, which is the next radial to be used in the time check. The pilot then continues to bold the 120° aircraft heading and flies to the 040° radial. As the pilot crosses this radial and the needle centers, he or she notes the time and finds that it has taken two minutes (120 seconds) to make the 10° radial change.




[frame="11 70"]Therefore, by dividing 120 seconds by 10, the pilot finds that there are 12 minutes remaining to fly to the station. Although this problem can be worked out using any degree of radial change, l0 degrees of radial change is the simplest and fastest to compute[/frame].
