I guess we've all got better at plotting LAT/LONG on our maps since we've had to do without Notamplot eh!? But if you want to save a bit of time, and/or double-check your manual plotting, then here's a way to cheat...
The excellent
www.streetmap.co.uk site will accept LAT/LONG input - so you can just go there, select Lat/Long, and then enter the coordinates in the appropriate format.
For example, a current NOTAM is:
OTH : FROM 02/10/12 00:01 TO PERM A1823/02
E)(MIL REF) AUS 02-10-DAPLC10/3101/BJ
FOLLOWING HANG GLIDING/PARASCENDING WINCH LAUNCHING SITE INTRODUCED
PARKFARM DOWN, BERKSHIRE
POSITION 513138N 0013429W
OPERATING HEIGHT 1500FT AGL
HOURS HJ
SITE ELEVATION 540FT AMSL.
(MIL REF U2243)
You would have to enter this position into Streetmap as
51:31:38,-1:34:29. Note the use of negative number for West longitude. East longitude would be a positive number.
You then get a small scale map back from Streetmap, highlighting the position entered. Zoom out a couple of steps to a more practical scale, and you will get a results like
this, which is then easy to plot on your ICAO chart with a chinagraph pencil.
So there you go! Still... I'd rather have Notamplot!!!
