User manual

U-See User Manual - Command Menu
Note: Each UAV has a flight envelope which restricts flight speed commands to minimum
and maximum values. Values out of this restriction are not accepted by the U-Pilot. Flight
envelopes may change for each flight mode and are pre-configured by Airelectronics, the
end user does not have to worry about it.
2.10.1.2 Normal and ECO flight laws
Optionally available for fixed wing vehicles only, it is possible to change the speed and
altitude holding strategy. This settings is independent of flight mode, but not all modes
allow command of Economic flight law. Whenever the user changes the mode, the flight
law will reset to normal.
Current flight law will be indicated by a blue background in the currently active flight law
button. Modes that do not accept change of flight law will have both buttons disabled.
Economic flight law will introduce a strategy in which speed is controlled by pitch angle
and altitude is controlled by throttle command. This will reduce altitude holding accuracy,
but, in exchange, throttle command will be executed much more slower.
Additionally, autopilot will not correct altitude errors in the positive, i.e. if the autopilot is
higher than commanded the throttle will be cut to reduce consumption, but not further
action will be taken.
Economic flight also enables gliding navigation and thermal soaring through the orbiting
mode combined with economic flight law.
However, as the altitude control is not as accurate, it should not be activated whenever
near the ground or when flying in airspace that requires strict vertical separation levels.
2.10.1.3 Vertical Performance limits
Optionally available autopilot feature. It may not apply to your software/autopilot pair.
Through this setting, vertical transition climb and descend can be limited. Current limit is
displayed in the selected vertical climb units or “Unlimited” is shown.
When operating unlimited or with a too high limit, the autopilot flight envelope limitations
still apply and transitions will be executed at maximum pre-configured safe values.
2.10.1.4 Available Fixed Wing Modes description
2.10.1.4.1 Manual mode
At this flight mode U-Pilot gives all the control to the external pilot.
This mode must be selected before the mission starts in order to do the Pre-Flight settings.
Be aware of the throttle stick specially in electric motors.
2.10.1.4.2 Semi-Manual
In this mode the manual pilot input commands will be interpreted as requested attitude
angle, instead of requested surface deflection. Autopilot will only control attitude
angles while in this mode, so it is responsibility of the manual pilot to maintain safe
altitude, safe flight speed and proper navigation.
2.10.1.4.3 Fly To mode
At this flight mode the UAV heads a destination point selected by the Computer Operator,
the destination point can be changed on real time just right clicking on the map.
Have in mind that if you have the “Flight plan editor” window opened, the right click will
be associated to flight plan waypoint set, and it won't change the Fly To point (indicated on
the map with a circle with “DP” in it).
When the destination point is reached the UAV automatically goes to orbiting mode using
the destination point as orbiting point.
