From the website:
Activating airplane mode will fully disable the cellular radio transmit and receive capabilities, which will prevent your phone from being reached from the cellular network
The baseband implements other functionality such as Wi-Fi and GPS functionality, but each of these components is separately sandboxed on the baseband and independent of each other.
adelina tuned on location (GPS) and airplane mode basically be a regular GPS phone?
Do you mean GPS works when using offline maps? I think it should work, but you can try it out and report back. That would be interesting to know, and probably very useful in emergencies in areas with no cell reception!
