FD and FD Pro own ship on IAL plate
Our company gave us trial version before releasing the approved EFB class 1 ( IPad) the ownship is displayed ONLY on enroute and taxi chart ( minimum EPE is 17mts for taxi to display ownship) and 200 for enroute.
Only in the trial version we were able to display ownship on app chart ( and radar minima) with an EPE of max 50mts
I think the limitation may be in the Company customised IAL or in the version of the FD Pro which is developed in accordance to Company/Customer specifications together with the approval of the Country Civil Aviation Authority
