This article will more or less be about the hand held ones, specifically the E6-B and CR types, while there also has been analogue electronic and digital electronic, ones over the years. | ||

All of them pretty much does the same thing. There's a lot of calculation that have to be made related to the direction you are flying in, the air speed you are flying at, the effect of the wind on the your direction and air speed: | All of them pretty much does the same thing. There's a lot of calculation during flight planning that have to be made related to the direction you are flying in, the air speed you are flying at, the effect of the wind on the your direction and air speed: | ||
* Firstly, all maps show ''true'' north, while navigation almost exclusively is done by ''magnetic'' north. The winds are also reported in true north. | * Firstly, all maps show ''true'' north, while navigation almost exclusively is done by ''magnetic'' north.

There have been many variants of flight computers over the years, but the two ones that seem to stay are the E6-B and CR variants. While both basically does the same calculations, they get to the result in different ways, which is also reflected in their appearance. Put in simple words: The E6-B has a sliding chart in the middle and the CR is bolted together in the middle | There have been many variants of flight computers over the years, but the two ones that seem to stay are the E6-B and CR variants.
