I definitely have the &amp;quot;charged iPad&amp;quot; on the checklist, I don&amp;#x27;t make assumptions and I make sure to charge it before flight. I use it for GPS altitude only as I have 2 baro altimeters and an old Garmin GPS, but the iPad&amp;#x27;s GPS is usually more precise to indicate current height above ground.
A 12 day battery life for a smartwatch I would only wear when flying is more than enough. I would not wear the smart watch on the ground, my regular watch is running without any maintenance for 21 years (Citizen EcoDrive).</text></item><item><author>billziss</author><text>I am no fighter pilot, but I (used to) fly airplanes, floatplanes and helicopters.
