In order to correct the takeoff altitude you need to go to Menu > Vol & Alt. dialog.
By default the Auto QNH checkbox is checked. Auto QNH will try to correct the takeoff altitude to your
current altitude by searching for a nearby airport or by using the Ground elevation at your location or (if
all else fails) using a very much averaged GPS altitude (but the latter is only a fallback and should not
normally happen since there is a worldwide terrain database already installed on each Oudie 4). Auto
QNH setting will give you a very good idea about the current pressure level and it works automatically
without your input.
If you want to change the altitude manually you should disable the Auto QNH navbox and enter the
takeoff altitude manually. If the
Linked checkbox is checked (which it is by default) then the pressure
level will increase accordingly.
Typically in a competition you could get a complete set of data from the competition organization. In this
case remove the Auto QNH checkbox AND the Linked checkbox. Enter the takeoff altitude AND the QNH
pressure given from the competition then press ok. This way you will see exactly the same altitudes
during your flight as the ones that you will be scored by later in the evening. DO NOT set the "linked"
checkbox back in this case because it will change the pressure level back to the "linked" value.
