Fixed Gun may be utilized during degraded systems operations, such as when the M-TADS or FCR are not available or unsuitable. Helmet sights are inherently inaccurate at long range due to aircraft vibration and therefore have a low probability of hit against targets beyond 1,000 meters. When engaging point targets ___________________ (without the use of the M-TADS or FCR) the crew should select Fixed Gun.
