In aircrafts any additional weight is extremely critical as it influences the maximum take-off weight and operational time. Therefore only the lightest and most advanced components are used and often even the operational height of the aircraft is considered in order to minimize the amour. Secondly, integrating amour into the aircraft is complicated due to the many items fitted onto the airframe like for instance seats, hatches, and fire extinguishers. The more, the airframe is not a completely stiff construction, but must be able to flex during flight and the armor installed must attached to be able to allow that.
Scanfiber has been involved in different projects, protecting various areas of several different types of aircrafts. Some systems have been permanent fits, other have been removable system.
