When the course deviation indicator (CDI) needle is centered during an omnireceiver check using a VOR test signal (VOT), the omnibearing selector (OBS) and the To/From indicator should read: a. 0 degrees TO or 180 degrees FROM, regardless of the pilot’s position from the VOT.
When the course deviation indicator (CDI) needle is centered during an omnireceiver check using a VOR test signal (VOT), the omnibearing selector (OBS) and the TO/FROM indicator should read A.180° FROM, only if the pilot is due north of the VOT. B.0° TO or 180° FROM, regardless of the pilot's position from the VOT.
A course deviation indicator (CDI) is an avionics instrument used in aircraft navigation to determine an aircraft's lateral position in relation to a course to or from a radio navigation beacon. If the location of the aircraft is to the left of this course, the needle deflects to the right, and vice versa.
The course deviation bar operates with a VOR/Localizer (VOR/LOC) or GPS navigation receiver to indicate left or right deviations from the course selected with the course select pointer; operating in the same manner, the angular movement of a conventional VOR/LOC needle indicates deviation from course.

The CDI indicates that theMoreLine just to extend that to determine whether right or left of course. The CDI indicates that the course is to the right of us so assuming we're headed the same direction. We are the left of course.
A selector that permits an operator to select the VOR (very high frequency omnidirectional radio-range) bearing on which he or she wishes to approach or leave the station.
Deflection is 10° deviation at full scale (each side), with each dot on the CDI representing 2°. A CDI might incorporate a horizontal needle to provide vertical guidance when used with a precision ILS approach where the glideslope is broadcast by another transmitter located on the ground.May 3, 2021
1. When the course deviation indicator (CDI) needle is centered during an omnireceiver check using a VOR test signal (VOT), the omnibearing selector (OBS) and the To/From indicator should read: a. 0 degrees TO or 180 degrees FROM, regardless of the pilot's position from the VOT.Oct 5, 2012
2.5 degreesOn most localizer courses, full deflection indicates 2.5 degrees. With a maximum one-quarter scale deflection maintained, “the aircraft will be aligned with the runway,” explains the Instrument Flying Handbook.Apr 1, 2014
So the term 3/4 scale deflection for an ILS means that at all times during the approach procedure, the needles must not exceed 3.75 dots (or 75% of the available space) on both lateral and vertical guidance needles. This explains it pretty well.Jan 16, 2017
OBS vs CDI The OBS (Omni-Bearing Selector) is the knob that the pilot adjusts. On the other hand, the CDI (Course Deviation Indicator) is the needle in the window that shows your desired course. So the pilot turns and sets the OBS but sees their course by looking at the CDI needle.
A standalone CDI (Course Deviation Indicator) is an instrument that shows your deviation from a VOR radial that is selected using the OBS (Omnibearing Selector) knob located on the instrument itself. An HSI (Horizontal Situation Indicator) is an entirely separate instrument that combines a CDI and a heading indicator.
The deviation bar is deviated to the left that means we are right of radial 006. Each dot and the edge of the bulls eye (center circle) equates to a 2 degree deviation. That means we are 5 degree right of radial 006.Jan 8, 2013
GNS 530 OBS button (what does it do?) According to the Garmin Manual, turning on the OBS function while using GPS steering will keep the aircraft on the current directional track and will disable tracking of the remaining waypoints on the flight plan.Oct 21, 2007
In the CDI instrument, the radial indicator is a needle which is clearly visible on the top of the instrument. If the location of the aircraft is to the left off course, the needle deflects to the right. If the location of the aircraft is to the right off course, the needle deflects to the left. If the location of the aircraft is on ...
CDI display is independent from the aircraft heading. Note that in the CDI instrument, the display is independent from the aircraft heading. This can be strange for novice pilots to instrument navigation. The instrument displays the information in the perspective of an aircraft with course equals heading.
If the course selector is rotated until the deviation needle is centred, the radial (magnetic course “FROM” the station) or its reciprocal (magnetic course “TO” the station) can be determined. The course deviation needle also moves to the right or left if the aircraft is flown or drifting away from the radial which is set in the course selector.
The white triangle is pointing to the bottom of the instrument. The yellow triangle represents the selected radial . Do not mix up the selected RADIAL on the compass card with aircraft HEADING. The two regions are dependent from the radial selected in the aircraft.
A mobile compass is present and can be rotated by using the omnibearing knob usually written as ”OBS”: When the course selector is rotated, the instrument moves the needle to indicate the position of the radial relative to the aircraft . If the course selector is rotated until the deviation needle is centred, the radial ...
