Users of this freeware toolset may like to know that a new version is
now available. The main change is an update to the magnetic variation
(declination) table using the latest IGRF10 model. This table is used
by the toolset in lat long (including great circle) calculations.

Pilot's Assistant is an Excel multi-page spreadsheet providing
information and calculations for flight planning (including fairly
realistic fuel planning), navigating (including wind corrections,
magnetic variations, lat long calculations, great circle routes),
computing various kinds of speeds and altitudes, and executing common
flying manoeuvres. It contains fuel/performance data for several
popular aircraft, and is intended to be a useful learning and
reference aid for several aspects of simulated flying.
