Question

Robyn...

Do you know how many decimal places the crew use when they enter the "numbers" into the flight computer?

Well I always round mine to 2 decimal places for general use, but I could imagine the third decimal place might make a difference on long flights.
In civil engineering we work to plus or minus 5mm over a 6000m distance, well we did when I was trained, but these days they user lasers and GPS stuff..so maybe even "tighter".

So the question is... how many decimal places are used when a crew inputs the data for mapping the flight?

Regards

p.s. the laser spelling came out like that when I entered the text..I mean LASER. done it again..why does it do that?
