Landing Options
A deep-stall can be performed automatically or manually. In an automated deep-stall, the operator
chooses where the aircraft should land on the map in Swift GCS. In flight, the aircraft will fly the
entire approach and landing using the aircraft's wind estimation to pick an optimal path.
With a manual deep-stall, the safety pilot needs to determine the wind direction and then choose
when and where to begin the landing. Once initiated, the safety pilot steers the aircraft during the
descent.
Auto Deep-Stall
For an auto deep-stall, the user chooses the landing location in Swift GCS. It is recommend to
physically check your landing spot before takeoff to ensure you are not accidentally landing on
hidden obstacles, and to verify that the location is actually where you want it. As such, there are two
helpful ways to do this in Swift GCS: use the Moving Base feature to verify location, or use the
aircraft location after it is powered on. Auto deep-stall must be done to a landing location that is at
the same elevation as where the aircraft was armed.
Lynx will automatically begin the landing sequence at the end of a mission or when commanded.
The auto deep-stall begins with the aircraft flying to the landing waypoint to loiter
(Item 1)
. The loiter
allows the aircraft to estimate the winds at the landing location. The loiter altitude, or entry altitude, is
typically 60 meters AGL but can be changed depending on obstacles or terrain. In general, a higher
entry altitude reduces landing accuracy.
Lynx will circle the landing spot at least once and then choose its approach path. The approach path
will attempt to land directly into the wind based on the aircraft's wind estimation. As such the aircraft
will exit the loiter with a tailwind and then circle back around to the landing spot facing into the wind
(Item 2)
. The approach path is displayed in the GCS once picked.
The aircraft flies the approach path and continues to update its estimate of when to begin the deep-
stall to hit the landing spot. This is indicated by a line that crosses the approach path
