Weight is an important consideration when choosing avionics as lower weight translates into fuel savings. There are several strategies that can be used to reduce the weight of a crash recorder, the following are four steps that can be taken to put a crash recorder ‘on a diet’:

  • Ultra-lightweight titanium crash tube design – Using the appropriate materials with computer aided analysis and design techniques can identify the best way to ensure that structural specifications are met with the least amount weight.
     
  • Modern electronics – Electronics and storage components have been constantly increasing in capability while reducing in size and cost. Newer crash recorders will have access to lighter and more integrated components than older designs.
     
  • Hard mounting recorders – By ensuring a recorder’s non-crash protected components are rugged, you can remove the requirement for, and weight of, anti-vibration mounts. Instead you can simply secure the unit directly to aircraft structure.
     
  • Lower cabling weight – As the crash recorders support more interfaces and contain integrated data acquisition, you can reduce or eliminate the need for a separate FDAU and its cabling and/ or implement lighter cabling strategies by using modern distributed networked data acquisition architectures.

Fortress

Curtiss-Wright’s Fortress cockpit image, voice and flight data recorder has taken all these design decisions and is implementing the manufacturing processes to create the most functional, low cost and light weight recorder capable of meeting current and future regulations.
