[TowerTalk] FAA form 7560-1 question

[Jim Lux]

Some GPS units can set their DATUM to NAD83.. GPS, by default, uses WGS84..
Off hand, I can't recall, but I think NAD83 and WGS84 are fairly close
(within a matter of a few meters)... The topo maps are generally done to
NAD27, which can be several tens (or hundreds) of meters different.  There
is a datum conversion program and web toolo on the web at either USGS or
NIMAs web site.. google for "datum conversion"...

What precision does the FAA want for it?

Jim, W6RMK
