SkyDemon Mobile Safety Features

As you fly, SkyDemon constantly monitors your trajectory, sending virtual radar pings into its chart data to scan for approaching features that could pose a hazard to flight.

Airspace Penetration Warnings

When your trajectory, both lateral and vertical, would take you into controlled or dangerous airspace, a warning is displayed and an alert sounded. This colour-coded warning instantly alerts you to the presence of the airspace, what the airspace is called and gives you a station and frequency to call to get clearance or information.

Red warnings are displayed for danger, restricted or prohibited areas, or for controlled airspace designated class A. Yellow warnings are for other controlled airspace. Purple warnings are displayed when there is NOTAMed airspace ahead, and other warnings can be turned on for ATZ, MATZ and Sporting Areas.

Warnings have two large buttons; one displays further information about the airspace (such as its vertical limits and times of activity) and the other dismisses it. Once dismissed no further warnings about that piece of airspace are shown for five minutes. You can configure which types of airspace trigger warnings and how many minutes away from the airspace you have to be.

Obstruction Proximity Warnings

Part of the data forming our detailed charts is full information on the location, altitude and height of fixed ground-based obstructions. These are always displayed in the approaching features instrument. When it is detected that your trajectory, both lateral and vertical, would take you close to an obstruction, a warning is displayed and an alert sounded. The warning shows the type of obstruction and advisory action.

The horizontal and vertical proximity thresholds for obstruction warnings are configurable in the application options, as is the number of minutes away the obstruction has to be. As with airspace warnings, an obstruction warning can be dismissed for a period of five minutes, after which time it will re-appear if the obstruction is still a threat.

Terrain Warnings

Although not designed to be used for IFR flight, SkyDemon includes terrain elevation information and spot elevations in its data. The elevation of the terrain ahead is always displayed in the approaching features instrument and when your trajectory would take you close to terrain, a warning is displayed with appropriate advisory action.

The horizontal and vertical proximity thresholds for terrain are configurable in the application options. Terrain warnings are not enabled by default.

Other Alerts

Various events are displayed onscreen transitively for a few seconds, with their own distinctive sounds, during flight. You will see and hear these alerts when:

• You Enter Airspace
• You Leave Airspace
• You Reach a Waypoint
• Battery State Changes

These can be very handy for remembering to tell ATC that you have entered or left a zone, or are turning for your next waypoint.
