750 Flight Modes
These are PX4 flight modes. They will differ from the IF800 TOMCAT and IF1200A Heavy Lift.
Altitude | The aircraft maintains altitude, but its horizontal position is controlled by the pilot. |
Position | The aircraft maintains its position, heading, and altitude using GPS. The roll, pitch, and yaw are controlled by the pilot as in Altitude mode, but when the sticks are neutral the aircraft will slow to a stop and maintain its current altitude and position. This mode is recommended for basic flying (and first flight). |
Return to Launch (RTL) | This mode is recommended for normal landings and for landing after an autonomous mission. When activated, the aircraft automatically returns to its Launch position and lands. The Launch position is the original takeoff location of the aircraft. If the aircraft is below an altitude of 30 meters, it first rises to 30 meters before returning to its Launch position in a straight line. Upon reaching its destination, the aircraft slowly descends until it lands. This altitude of 30 meters can be adjusted in the ‘Safety’ tab within QGroundControl. |
NOTE | If the aircraft behaves unexpectedly while flying autonomously, switch to Position mode to regain control. Moving a joystick during an autonomous mission reverts control back to the pilot. |
The IF750 automatically returns to the launch site as a failsafe when the battery voltage gets too low to continue flight; visually monitor the battery level in QGC and replace the batteries conservatively to mitigate risk. |
Control | Flight Mode | Location on Hand Controller |
"A" Button | Position | HereLink: Button at the bottom of the front panel. Jeti DS-12: Top and mid-position of three-way switch on upper-right of front panel. |
"Home" Button | Return to Launch (RTL) |
Note: The current flight mode is indicated in the top right corner of the QGC display (see below). Altitude mode (see below) is usually the default mode until the aircraft has been outside long enough to obtain a GPS lock.
Selecting a Flight Mode on the LRT Jeti DS-12
On the Jeti DS-12, there is a three-position switch on the upper-right corner of the front (see below) for selecting one of two flight modes:
Top and middle: Position
Bottom: Return to Launch
Note: When the Mode Switch on the Jeti DS-12 (see figure 9 below), is used to switch flight modes, the QGroundControl display on the ground control station updates to show the new flight mode.
