STANAG 3350 STANAG 3350 STANAG 3350 (Analogue Video Standard for Aircraft System Applications) is a NATO analog video Standardization Agreement for military aircraft avionics. Video-capable sensors such as radars, FLIR, or video-guided missiles often provide a STANAG 3350 video output. STANAG3350 video is supplied as a component RGB signal with timing similar to a corresponding civilian composite video standard such as NTSC, PAL, or RS-343. Only the vertical and carrier frequency of the signal are defined by the standard, the horizontal resolution can vary from one implementation to another and still satisfy the STANAG 3350 standard. The three different versions of the
