Summary
*******

This software provides much of the functionality of an E6-B flight computer 
on the TI-82 calculator platform.


*******************
Using this software
*******************

Copy the e86b.82g group file to your TI-82 calculator. It will expand into
five TI-BASIC program files:

-E86B
-WTBAL
-AIR
-WIND
-XWIND

E86B is the main prgram file; it calls the other four programs for weight
and balance, atmospheric (incl. density altitude, relative humidity, and
cumulus cloud bases), wind triangle, and landing crosswind calculations.

Operation is straightforward; cursor keys select menu items from the E86-B
screen.
