Abstract: A fairing for an aircraft is provided, having a roll axis with a turret coupled to the front end of the fairing for rotation about the roll axis. An opening is formed through the front end of the turret in which a tracking member is supported for rotation between forward and rearward positions about a pitch axis transverse to the roll axis. The tracking member has a cavity with a primary optical mirror at one end and a transparent shield at an opposite end with a primary optical axis extending between the mirror and shield. The shield is slanted to minimize wind turbulence when the tracking member is located in a rearward position.
