On Scene Mode
When a GDL 88 (with software v3.00, or later) or GTX 345 is installed with
a GTN in a helicopter, the GTN provides controls for enabling/disabling “On
Scene” mode. “On Scene” mode decreases traffic alerts when operating near
other helicopters (e.g., news reporting).
1. While viewing the Traffic page, touch the
Menu
key.
2. Touch the
On Scene
key to enable/disable On Scene mode.
9.5.3
Rotorcraft Traffic Page Orientation
NOTE
: Rotorcraft Traffic Page Orientation functionality is available in
software v5.12 or later.
When flying at low speeds in a helicopter, heading may not always be closely
aligned with track (it could easily be up to 180 degrees different). If the GTN is
interfaced with a heading source, the ADS-B traffic page will remain fixed with
the ownship heading pointed up. However, if heading is not being received by
the GTN, the display of ADS-B traffic will be unavailable.
When one of the following conditions is true, the ADS-B traffic page will be
unavailable and a "Display Unavailable" banner will be displayed.
• Ownship directionality is invalid (no valid heading or track)
• GPS ground speed is less than 15 knots and ownship heading is not
available
While the traffic display is unavailable due to these conditions, traffic alerts
will be provided in a non-bearing textual form at the top of the traffic page.
