WiFi only IPad2 and GPS
First post so I apologize if this is a resurrection, but I could not find the specifics and an answer to my question, that being:
I will soon be operating in a widebody cockpit using an FAA approved IPad2 with no, again, no 3G capability.
This IPad in addition to having all my Jepps, also carries all my MEL and Operations Handbooks.
I am looking for a portable GPS unit, Bluetooth or not, that works in a cockpit above 30K feet to attach to my IPad. Obviously the cockpit has window heat elements that may cause interference. Also, the unit must be able to keep up with jet speeds with an additional 150 kt jetstream tailwind.
Should I be concerned with regards to Bluetooth and onboard nav systems?
