The only instrument to be considered for maximum altitude is the
Oudie 3 itself. With this instrument now being compared and adapted to air
pressure changes to adjust the right QNH altitude.

My highest altitude shown by Oudie 3 is 2,791 meters QNH. Subtracting 26 m gives
2,765 meters msl and therefore 10 meters below the maximum height limit.

Let's see what we can calculate given the Oudie 3 and not the
SensBox.

At goal SeeYou with QNH set at 1022.1 in Flight Properties, goal pressure
altitude is 3,663' or 1,116.5 meters. The GPS altitude is 3,560' or 1,085
meters. So the pressure altitude at goal is 31.5 meters above the GPS altitude
displayed on the Oudie 3 track log. The actual goal altitude at the position
shown on the Oudie 3 is 1,084.6 meters.

SeeYou displays Tom's highest pressure altitude at 9,218' or 2,809.6 meters.
This is 34.6 meters higher than the maximum altitude. Subtract 31.5 meters and
he is 3.1 meters over the limit.

We're getting to the width of cat whiskers here.
