2. The Performance -- Climb/Descent screen has three new values:
Feet to Climb/Desc, Time to Climb/Desc, and NM Travelled.

3. The Conversions -- Time/Distance conversion screen has two changes:
"Time (Decimal)" has been renamed to "Time (Decimal Hrs)";
New value "Time (Decimal Mins)" added.

4. One completely new screen have been added to the Wind and Weather menu:
Sunrise/Sunset -- calculates official sunrise/sunset and Civil Twilight within 2 minutes for any location on the globe.

5. The Lat/Long Main Menu item has been renamed to "Navigation", along with the following changes:
-- The original Lat/Long screen is now a menu item on the Navigation menu.
-- Two addition new screens are available on the Navigation menu:
Time/Distance To Station -- Calculates time and distance to station by turning slightly off course and timing.
Off Course -- Calculates correction angle to fly when off course by a known amount.

6. Several atmospheric constants have been updated in the calculations to correspond with the 1976 US/ICAO Standard Atmosphere. The effects
of this change are minor, and primarily aimed at very high speeds (> Mach 0.6) and high altitudes (> 36K feet). The largest differences would be
seen primarily at true airspeeds close to Mach 1.0.
