13.4.3 Course Deviation Indicator
The yellow needle and the central bar form a CDI with a slight difference. It isn’t tuned to a VOR, but is indicating your deviation from the flight plan track line displayed on the map. The sensitivity varies with distance from destination. Full Scale Deflection (FSD) for various distances is shown in the table below. Distance from Waypoint
Sensitivity
More than 35nm
FSD = 5nm from track
Between 2nm and 35nm
FSD = 1.2nm from track
Less than 2nm
FSD = 0.25nm from track
This is the same as the sensitivity of an ILS localiser. 13.4.4 Automatic Direction Finder
This is an ADF with a difference. The small green arrow works exactly like an ADF tuned to an NDB, but it points directly to your next waypoint. It is not influenced by thunderstorms or mountains of iron ore, so is more reliable than a real world ADF (not that magnetic mountains are simulated in FS!) It does get more sensitive as you get nearer to the waypoint, and swings round in the normal way an ADF needle does as you pass the waypoint. When Plan‐G decides it is time to look for the next waypoint, it will swing round automatically to point to the new one. If you are directly on track, this will be the instant that the aircraft passes over the waypoint. If you are off track a little, it tends to move round to about 150o before changing, so don’t chase the needle as you near the waypoint. 13.4.5 Descent Profile Indicator
The fourth feature is the descent profile indicator. Whether you create an altitude profile or not, Plan‐G will calculate a Top of Descent point along your route. As you near the Top of Descent, the profile bar (a small green letterbox shaped rectangle) appears on the HIS dial, and descends downwards. This is similar to a glideslope indicator and shows the rate of descent you need to achieve to maintain your VNAV profile. It works in the same sense as an ILS glideslope indicator. If the bar is below the centre, you should increase your descent rate, and if it above centre you should slow your descent rate. The HSI tooltip contains context information about your position on the profile. Full scale deflection on the profile bar is 1 degree above or below the profile (the same as a normal ILS). This mimics the standard handheld Garmin (e.g. 296, or 496) VNAV functionality. If you wish to disable the profile bar, set the Profile to 0ft/minute, accessed from the “File” Tab in Options/GPS Panel. 13.5 Traffic
The Traffic data expander shows a table of all the FSX/FS9 AI or online traffic within a defined distance of the user aircraft. The maximum distance for the display of AI traffic can be user‐defined in the Global Options. The default setting is 50 nautical miles. Page 43 of 106
