Abstract : Conclusions: (a) The standard issue Signal Lamp M-227, using the white light, can be seen and identified by a helicopter flying at 2000 feet MSL at a distance of 8-10 miles, visibility permitting. (b) The Signal Lamp M-227, using the red filter can be seen and identified by a helicopter flying at 2000 feet MSL, at a distance of 3-5 miles, visibility permitting. (c) The standard military flashlights can be seen and identified by a helicopter flying at 2000 feet MSL at distances of 3 miles with the white light and 1 mile with the red light, visibility permitting. (d) The Signal Lamp M-227 can provide initial site acquisition for the helicopter at ranges of 8-10 miles and can provide directional navigational assistance to within 1/2 mile of the landing site. (e) The Signal Lamp M-227 provides for greater security during use than do the standard hooded military flashlights. Recommendations: (a) That the Signal Lamp Equipment SE-11/SE-11A be adopted for use as an emergency evacuation mission helicopter signaling light with an added capability as a visual communications device. (b) That the recommended allowances for the Signal Lamp Equipment SE-11/SE-11A be adopted. (c) That the recommended concept of employment for the Signal Lamp Equipment SE-11/SE-11A be adopted.
