Many HSI's are coupled to auto pilots and may allow course selection via a heading knob if they are connected to do so. it provides both left right deviation along with glide slope information as well as heading indication in turns. Is a CDI and Heading Indicator packed into one unit. When on an instrument approach the CDI is used to track the left/right deviation from the runway (not a VOR). For instrument flying you also need to track the glide slope for an approach and thus vertical deviation may also be displayed on a CDI. When tracking a radial you only track left/right deviation and thus only a single needle is required (the first picture you have). The knob allows the selection (via the outer ring) of the radial (course) you wish to track from a VOR ground station. You are suggested to use one game capture per scene. Next, go to the Sources box and press the '+' button at the bottom to select Game Capture and add a new source named after your game. A scene will be created automatically when you launch OBS smoothly. The OBS (Omni Bearing Selector) knob is on the CDI, it is not its own instrument. After a successful installation, run OBS on your computer. If the location of the aircraft is to the left of course, the needle deflects to the right, and vice versa. Due to their functionality they need to be periodically aligned with the compass.Ī course deviation indicator (CDI) is an avionics instrument used in aircraft navigation to determine an aircraft's lateral position in relation to a course. They simple provide an alternative to the compass and are generally used when the compass reading may be inaccurate (non straight and level flight). The magnetic compass difficult to interpret. Indicator, however, is not affected by the forces that make To accomplish, particularly in turbulent air. Making straight flight and precision turns to headings difficult Errors in the magnetic compass are numerous, Instrument designed to facilitate the use of the magneticĬompass. The heading indicator is fundamentally a mechanical Check out this manual from the FAA on flight instruments
