BRL: Am I allowed to say this?
Skua:
Obviously the flight planning sotware which is right for you depends on the type of flying you do.
I'm a GA PPL flying mixed IFR & VFR in UK and Europe. I have used Navbox for about five years and I'm very happy with it. Briefly, it is easy to use, the update service works well, the publishers respond sensibly and quickly to comments and the service is wide enough in coverage. I have considered other brands, but they don't seem to offer the same value for money as Navbox.
