L-1011 Navigation: Radar Control Head (34-17)

The radar control head is located on the aft center console. The radar scoops are mounted on the opposite ends of the Capt. and F/O's instrument panels.

A selector is provided to select either the No.1 or No.2 radar system. With the No.1 selected the No.1 REC/TRANS and No.1 VG/INS are being used to align the antenna and produce the radar scope images.  With the No.2 selected, the No.2 REC/TRANS and No.2 VG/INS are being used. Again, both scope would now show radar images from the No.2 system. On the L-1011 it is not possible to operate the two radar scopes on opposite systems.

The VG/INS provides stabilization to the radar antenna.
