Select desired Navaid type and settings. Drag aircraft on horizontal or vertical panels to change the aircraft's position in relation to the facility. IfNorth Up is selected aircraft heading changes can be set by positioning the cursor close to the aircraft on the horizontal panel then clicking the button when a "-" or "+" appears. IfHeading Up is selected, aircraft heading changes can be set by positioning the cursor close to the navigational facility on the horizontal panel then clicking the button when a "-" or "+" appears.
WhenHeading Up is selected, even though it may seem that the aircraft rotates around the navigational facility, the aircraft remains in the same position when changing heading. The reason for this is that the display will always show the navigational facility in the center of the display. This means that regardless ifNorth Up orHeading Up is selected the aircrafts position will always be relative to the navigational facility.
Compass Rose - Used as an aid to show the orientation of the Horizontal Navigation panel. It serves the same purpose
as the compass rose symbol on IFR enroute charts to show direction in relation to the magnetic north.
To / From Region - Shows on the Horizontal Navigation panel the regions where the VOR flag will display
To or From depending on where the aircraft is positioned.
Projection Flags - IFR approach plates have a profile view that displays the sideways vertical projection of the approach
course. The projection flags serve to help visualize how and where this projection is made from the Horizontal Panel
view. Notice how the aircraft moves on the Horizontal panel when it is dragged on the Vertical panel and vice
versa. The movement is made in alignment with the projection flags.
Horizontal Panel - Displays the horizontal position of the aircraft in relation to the navigational facility the same
way an IFR enroute chart or an approach plate's plan view would.
Vertical Panel - Displays the vertical position of the aircraft in relation to the navigational facility the same
way an approach plate's profile view would. It is used for several purposes:
1. For the glide slope feature.
2. Higher altitudes increase the diameter of the cone of confusion (zone above and around the VOR facility where
the VOR receiver does not work properly and will typically display a red NAV flag)
