What is the edit mode for?\\
**Don’t need edit mode, can use settings mode and up/down to select parameter then use speaker to go into edit mode.**

If we are not going to detect end of flight automatically, then how to we signal end of flight?\\
**This is going to take some thinking so that false stops are not triggered.**

For the volume, it seems like there should there be a visual indicator for the off/quite/loud on the display, or at least on the settings page.\\
**Good idea if it can fit, lower priority.**

Memory / Log Book -> Call it one or the other not both… Confusing, especially since the menu says only Log Book.\\
**Okay, hadn’t decided on name yet.**

Menu Items:\\
Standby		-> Enter “Standby” mode\\
Flight		-> Enter “Flight” mode\\
Log Book	-> Enter “Log Book” mode\\
Settings	-> Enter “Settings” mode\\
Exit		-> Return to previous mode\\

**Cannot goto to Time mode from menu!**


How will user reset max settings?\\
**Maybe they will not, just logged with flight data**

Units:\\
**English alt: feet, velocity: ft/min**\\
**Metric: alt: m, velocity: m/s**\\

Should have user setting for velocity threshold to start flight mode.\\
**Probably good idea**

How should we detect end of flight mode?  Vel < end flight thresh for greater than 20 seconds, user settable.\\
**These questions may be easier after a few flights and logging flight data…  Do not want to ever have a false end of flight!**

On the Time display, what at the two values shown?\\
**Time of day HH:MM -> Top line**\\
**Flight Time HH:MM-> Bottom line**\\

===== Serial Communications (USB) =====
