I would like to talk about an issue of sleep mode setting. We all know that we're able to set our sleeping time through garmin app and our watch will switch to sleep mode whenever the time has come. However, it's not practical since many of us don't sleep or wake at the same period time everyday. For pilots, our worktime varies by different planned schedule. Normally, when the plane take off, the watch will automatically start the fly activity. This is no doubt a very great design by reducing our workload or maybe sometimes we just forget to start the activity for during takeoff and landing is our busiest and most critical phase of the flight. BUT! Like I mentioned earlier, the watch won't turn off sleep mode unless is your setting wake time or by manual. For example, my wake time sets at 0800, but my flight starts at 0600. Therefore, the watch will completely miss out the 2 hours flight record, and not to mention that I already wake up at 0400. It is so bizarre that the watch can't sense I'm already awake since I keep moving and it's clearly not a sleeping person will do. I understand that it won't take much time to manually do all the settings, but if it can be done automatically, why not? and I ensure you that this thoughtful design will be highly appreciated.
