• FAA AC 150/5345-44
• FAA Engineering Brief No. 67

On military airports as;

• Runway Distance Remaining Signs indicate the distance to the end of the active runway to the pilot
• Arresting Gear Markers (or Moon Board) is used to indicate the location of the aircraft arresting cable on the runway

• FAA Compliant
• Legend on one or two sides
• Internally lighted
• Corrosion resistant and durable against effects of sun, jet blast, vibration, dust, storm, rain, snow, ice and deicing agents  
• Economical to run; low power demand
• Easy to maintain; LED Lifetime is more than 50.000 hours 
• Modular design with common mechanical and electrical components throughout entire sign range
• Uniform LED bar spacing provides highly uniform distribution of light, no hot spots or shadows
• Vertical panels keep dirt from accumulating
• Low weight, yet rigid construction thanks to aluminum extruded profiles and panels
• Seamless polycarbonate legend panels are resistant to UV, abrasion and high temperatures
• The 4mm thick panels provide improved resistance to jet blasts and strong winds
• EMA standard signs can withstand a wind load of 322 km/h (200 mph)
• Frangibility compliance to ICAO, FAA and ENV requirements, attained by grooves on legs
• Improved safety with external ON/OFF switch
• Reliable operation from -40ºC to +55ºC
