I fly day VFR with an iPad2 and Foreflight, using a swiveling Ram Mount on the left edge of my cockpit. The ipad2 is the wifi-only model, so I've added the BadElf GPS. No screen covers, coatings, or films.
To start the day I disable the Passcode lock and set full brightness in the iPad settings and full brightness in the Foreflight settings. My battery charge life for those settings drops to maybe 6 - 7 hours instead of the nominal 10 hours. On a x-country I'll grab some recharge time during the stops.
Often there are conditions where the iPad2 glass reflects objects like chrome shoulder harness hardware and light clothing. RECOMMEND DARK CLOTHING and non-reflective objects as much as possible.
Using these tips I can see the iPad2 display and easily see and use ForeFlight approximately 90% of the time. Worth every penny of $75/year for current charts.
Also flying with Garmin 496 (no subscriptions) and XM weather. The XM subscription is worth $35/month for WX and TFRs.
The 496 drives the Trio Pro Pilot. Neither unit has ever lost GPS position lock.
Flying with two affordable independent and airplane electrical failure-proof GPS mapping systems! What a fantastic improvement since learning to fly in 1975.
My experiences over 10 months and approx 150 hours of flight.
