On the Course Deviation Indicator we select the radial and together the needle and TO / FR flag shows our position.
3.
Similar to other precision landing systems, lateral and vertical guidance may be displayed on conventional course deviation indicators or incorporated into multipurpose cockpit displays.
4.
You can also use the 1 in 60 rule to approximate your distance from a VOR by flying 90 degrees to a radial and timing how long it takes to fly 10 degrees ( the limit of the course deviation indicator ).
5.
The Bendix / King KLN-90B controller is almost always linked to a GPS antenna, and may also include connections to other flight instruments such as an external Course Deviation Indicator ( CDI ) or horizontal situation indicator ( HSI ), ELT ), autopilot, and external annunciators.
6.
The aircraft was required to maintain the assigned heading of 220 degrees, until it could receive the signals from Bethel, then it could fly direct to Bethel, as instructed by ATC, by centering the VOR " to " course deviation indicator ( CDI ) and then engaging the auto pilot in the VOR / LOC mode.
7.
An aircraft can follow a specific path from station to station by tuning into the successive stations on the VOR receiver, and then either following the desired course on a Radio Magnetic Indicator, or setting it on a Course Deviation Indicator ( CDI ) or a Horizontal Situation Indicator ( HSI, a more sophisticated version of the VOR indicator ) and keeping a course pointer centred on the display.
