If you need the limits screen to do something it can't, please contact me and send me a scan (or picture) of the relating pages in the Pilot's Handbook for your aircraft.

- Fixed issue where the simple template for W&B would show the total CG for both total CG and Zero Fuel CG.
- Enhanced W&B graph points to plot in green if within envelope and red if outside.

- Weight and Balance will now plot your graph to show you your envelop (simple and moderate templates)! Look on the Limits screen.
- On Weight and Balance screens, you will not need to clear 0's out of the fields to begin putting in your value.
- "Distance for Descent" now called "Distance & Time for Descent", and will now show time required for descent in minutes

Version 1.18.3
- Enhanced limits screen to be able to handle slightly more complicated envelopes.
- Moved Great Circle and Course calculation in the Navigation list so that it would be in alphabetical order.

Version 1.18.2:
- Weight and Balance Simple template will auto-clear the fuel weight when the volume is changed.
- Renamed calculation "Course/Distance from 2 Lat/Lons" to "Great Circle and Course"

Version 1.18.1:

This is a small update to improve the Limits screen for Weight and Balance.

Enhancements:

- I have changed the Limits entry screen for Weight and Balance so that the redundant point values for the envelope do not need to be entered, they will be inferred from the previous entered point.

- The limits screen will now check your points to be sure they create a correct envelope "shape". If not, you will be presented with a warning.

- The simple weight and balance template will automatically update values after you edit a field, you do not have to tap "update values" anymore.

Version 1.18.0:

Additions:
- Distance for Descent - Gives the distance it will take to Descent to the desired altitude.
- Weight and Balance now allows you to define CG limits for the simple and moderate template! If you are inside the envelope, your results will be shown in green. If you are outside the envelope, your results will be in red. The helicopter template will be done soon. I am still hoping to get a graph plot integrated as well in a future update.

Fixes and Changes:
- Fixed issue that caused leg calculator not to update the unit labels when the user changed a unit setting after loading the leg calculator screen.
- Updated W&B moderate template screen to be a bit more intuitive in its layout.
- W&B moderate template table cell text will now scale down if values grow very large.
- Adjusted layout of Heli W&B cell slightly.
- About screen changes.
