Little rant coming on.
Whichever electronics maker first coined the term "Airplane Mode" should be forced to give all flight attendants $100. Why? Because many passengers say, "Oh it's in airplane mode so it's okay". It's not.
Flight attendants are governed by FAA policies. Advisory Circular 91-21.1B has the in's and outs. The basics is everything must be off. Nowhere in the circular is "Airplane Mode" mentioned. Off is off.
Unless you are an expert in electronics and have tested each device you carry to make 100% certain nothing is emitting from the device while in airplane mode, just turn the damn thing off. Hmm no not good enough....just turn the damn thing off.
It irks me when, right before or upon landing, I hear the clicking in my headset from GSM cell phones searching for a signal (CDMA doesn't do this). Is your life really that important you can't wait 30 second for the plane to clear the runway? Don't get me started how annoyed I get when I am in the cabin (deadheading/nonreving) and I see passengers turn on their cell phones right before/during touchdown.
I love electronics. I travel with a cell phone, Ipad, a Kindle and a Zune HD. All are turned off while I fly. Heck it saves battery life!
So in closing....dear traveling public turn your devices all the way off. Dear electronics makers....stop using the term "airplane mode."
