I am not sure the GPS works in airplane mode as it is an RF Receiver and most RF Receivers make a RF signal as well.. Google "Fox Hole Radio" for an explanation.
(The fox hole radio does NOT generate RF that can be detected).
Also does the I-Phone store the area map.. Android's do not ... by default.. but you can store an area map if you wish.
Carry a back up emergency re-charger would be my suggestion.
My I phone 7 GPS system (Copilot) works in airplane mode. Don't all these newer smart phone have a stand alone GPS system?
