= AltitudeControl =

'''__INFO__:''' For this function the altitude sensor on the FlightCtrl is required. 
<<BR>><<BR>>

== Function ==

The function "!AltitudeHold" makes it possible for you that the !MikroKopter holds automatically the height without a re-adjustment by the control-sticks. <<BR>>
Here the Kopter uses the altitude sensor on the FlightCtrl. For a proper function the sensor should be protected from light and wind and should be installed under a hood.<<BR>>
But also a packing of the sensor is possible. A describtion how that works you will find here: [[en/heightsensor#Packing_the_air_pressure_sensor|Altitude sensor]].<<BR>><<BR>>

To use now the function you must activate the function ''"Altitude hold active"'' in the KopterTool and you need to assign that to a switch channel.<<BR>>
Information you can find here: [[en/Sender#A1_channel_for:_.22Altitude_Hold.22|Altitude Hold]]<<BR>><<BR>>

On your transmitter this switch channel will be assigned to a 2-way switch. Is that one enabled the function "!AltitudeHold" is ON. <<BR>><<BR>>

With an activated function you can choose between two types of height control:


== Height Limit ==

The "Height control" (also called "Cover-Height control") limits, like the name says, the height. <<BR>>
If the height control was selected and turned on during a flight the Kopter will climb a few meters more while pushing the throttle-stick. Then the Kopter will stop climbing.<<BR>>
In that way you can leave the throttle on "full power" and the Kopter will not climb further. <<BR>>
(How far the Kopter will climb after switching on the function you can determine in the setting "Altitude P". A describtion you will find here: [[en/MK-Parameter/Altitude|Altitude P]])



== Vario-Height/~Altitude ==

Most of the functions of the Kopter (i.e. the !WaypointFlight or the Failsafe) are determined for the Vario-Height. Therefore, this mode should preferably be selected. <<BR>><<BR>>

If this height control was chosen the Kopter will hold with an approximatly middle-position of the Gas/Throttle-Stick automatically the current height/altituide. <<BR>><<BR>>

If you move now the Gas/Throttle-Stick either way up or down there will be not more or less throttle as maybe suspected. <<BR>>
With this function the nominal height will be shifted upwards or downwards.<<BR>>
The Kopter is following this shifting automatically and indicates that throughout "beeps" on the Kopter.<<BR>>
If you move the Gas/Throttle-Stick back into the middle-position the Kopter will keep automatically the new position.
