DGIV calculator

[Hudson180]

Hello, I am new at using the Delta Glider IV. I am trying to do a trip from the Earth to the Moon. I am trying to use the computer's calculator in order to get a launch heading. I follow the formula exactly as the instructions say, and I keep getting a result called "-1#IND". What does this mean ? Because I know it is not a heading..am I doing anything wrong ?

It happens to me too. We must repeat the process (it's written in the doc) and after his walked

Usually, it means that you didn't enter a good data. Check that you had enter your latitude and not your longitude.

I'm pretty sure I did enter my latitude. Latitude means your position from the equator, correct ?

[Bibi Uncle]

Check there : http://en.wikipedia.org/wiki/Geographic_coordinate_system. Latitude is your 90° N = North pole and 90° S = South pole. 0° = Equator.

In case you get frustrated there's always the interplantery mfd. I can get to the moon in 8hr's with a iv of 9k. It also automatically adjust your attitude and does burn for you.

This could be because the Moon's inclination is lower than your launch point's altitude. In this case, you should launch to a heading of 90 degrees. AlignPlanes can be used for timing - launch when RInc is at it's lowest. A plane change may be required later, although with the moon, a couple degrees RInc is workable.
