differences in lat/long fs2004

[Graham Pollitt]

I slew to a position of N33* 56.33', W118* 24.29' at KJFK

This converted to decimal is 33.9425, -118.4081

If this value is read via FSUIPC within FSinterrogate I get the decimal value of 33.93883, -118.40483. Converting this back to DHM gives value of N33* 56.24', W118* 24.17'.

Why is the value read back via FSUIPC different to the value that FS2004 thinks I am currently in?

thanks

No it isn't. It's 33.938833 and 118.404833.

I think you are mixing up minutes (56.33') with minutes and seconds (56' 33").

It isn't, it is identical. They come from the same place in FS. You need to understand the units.

so FS2004 format is Deg Hr Min?

No. there are no hours! And the format is user selectable, I think -- probably via unpublished options in the CFG file. But you can always tell from the way it is presented. You actually showed them in the Degrees and Minutes format:

I slew to a position of N33* 56.33', W118* 24.29'

See that little sign, ' ? That means "minutes". There's a seconds sign, ". If the format is degrees/minutes/seconds it looks like this:

N33* 56' 33"

When only minutes, no seconds, are given you get the decimal point indicating that the following digits are decimal fractions.

And of course you can also have just degrees with a longer fractional part for similar accuracy.

Gotcha Mr D :lol:

What I was doing, as you correctly pointed out, was dividing both parts after the degree ie 33degs then 56/60 and 33/60.

What I should have done is 33degs then divide 56/60 and then .33/60.

Yes, or more simply 33 degrees and 56.33/60. ;-)
