Simply add this script:

using maddox.game;
using maddox.game.world;
using part;

public class Mission : AMission
{

    public override void OnPlaceEnter(Player player, AiActor actor, int placeIndex)
    {
        base.OnPlaceEnter(player, actor, placeIndex);

        AiAircraft aircraft = actor as AiAircraft;
        if (aircraft != null)
        {
            GamePlay.gpLogServer(null, "Sprit: {0}", new object[]{ aircraft.getParameter(ParameterTypes.S_FuelReserve, -1)});
        }
    }
}

It shows the Current Fuel quantity of the plane you entered.

Ive tested the Heinkles with 50% Fuel - no problems in Game they have 50% Fuel.
