2.6 Miscellaneous Function Information

2.6.1 Horizontal Datum

The horizontal datum can be activated and switched off via PC conﬁguration software. It is

acted as the horizontal level reference of the viewed picture.

2.6.2 Flight Recorder Status

Once a formatted TF card is inserted to the OSD main board, the ﬂight recorder status will

be indicating “TF Card Ready” in “landed” mode. The indication will be switched to

“Recording Activated” automatically once the system operating mode is changed to “taken-

off” mode, and the real time ﬂight data including position coordinate, battery voltage,

current, speed, altitude, etc., will be captured and stored in the TF card. Until the ground

speed of the plane is less than 5KM/H or equivalent value in MPH for more than 2

seconds, the OSD system will treat the plane is landed, where the system operation mode

is switched back to “landed” mode, and this status will be switched back to “TF Card

Ready” indication. In case the TF card is missing or the OSD main board fails to

communicate with the TF card (e.g.. TF card is not formatted correctly), the ﬂight recorder

status will indicating “TF Card Error”, that reminds the user to check the TF storage card.

This ﬂight recorder function can be switched off in the OSD conﬁguration menu or via PC

conﬁguration software. Once it is switched off, there will not be any status to be shown on

the bottom of screen.
