How does a VOR receiver know what radial of a VOR station that it is on?
To identify the radial that the aircraft is on, center the CDI with a From indication. The number on the top of the course index is the radial that you are on. To intercept and fly a radial away from a station, the pilot should turn the OBS until the desired radial is on top of the VOR indicator.
How is VOR distance calculated?
The distance from the station is computed by multiplying TAS or GS (in miles per minute) by the previously determined time in minutes. For example, if the aircraft is 7.5 minutes from station, flying at a TAS of 120 knots or 2 NM per minute, the distance from station is 15 NM (7.5 × 2 = 15).
How do I read a CDI file?
On the CDI instrument just read the number displayed on the compass card (±90° of the radial). In the left figure above, the shortest path to join the VOR radial is 340° (=070°-090°) (blue straight arrow). The VOR is located in the sector between 340° and 070° as we are in the TO region.
What is radial VOR?
A magnetic bearing extending from a VOR/VORTAC/TACAN. ( Source: UK CAA) Bearing. The horizontal direction to or from any point, usually measured clockwise from true north, magnetic north, or some other reference point through 360 degrees. (
How do I do these VOR time and distance calculations?
How do I do these VOR time and distance calculations? A pilot tracking a VOR turns 90 degrees from current heading. The pilot notes that it takes 3.0 minutes for the plane to intercept the radial 5 degrees from where it previously was. What is the time to VOR?
How do you fly a radial inbound to a VOR station?
To fly a specific VOR radial inbound to a VOR station, use the OBS to place the radial you want to fly inbound on the reciprocal course index on the bottom of the VOR indicator. You should have a To indication, and the CDI needle will deflect in the direction you need to turn to get to the station.
What is the ground track heading on a VOR?
At time t (1) an airborne VOR receiver shows that the aircraft is on the 30deg radial from a VOR station. The pilot maintains a ground track heading of 120deg with respect to magnetic North and 120 knots ground speed.
Where is the aircraft located in the VOR station?
The aircraft is found in the 30 degree radial from the VOR station at time T (1) and T (2). During the 10 minutes between T (1) and T (2) the aircraft maintains a heading of 120 degrees from magnetic north at 120 knots ground speed. The question goes like so:
