A new FAA policy encourages general aviation aircraft owners to voluntary install safety equipment on airplanes and helicopters that is not required by the agency’s regulations.
The new policy will reduce costs and streamline the installation of Non-Required Safety Enhancing Equipment (NORSEE) into the general aviation fleet, according to FAA officials.
The policy is the result of industry and government collaboration under the General Aviation Joint Steering Committee and expands a 2014 policy that simplified the design approval requirements for an angle of attack (AOA) indicator.
AOA devices can be added to small planes to supplement airspeed indicators and stall warning systems, alerting pilots of a low airspeed condition before an aerodynamic stall occurs. Such stalls are particularly dangerous during takeoff and landing.
NORSEE includes avionics, electronic instruments, displays and mechanical equipment. Equipment approved as NORSEE increases overall situational awareness; provides additional information other than the aircraft primary system; provides independent warning, cautionary, or advisory indications; and provides additional occupant safety protection.
Examples of NORSEE equipment include traffic advisory systems, terrain awareness and warning systems; attitude indicators; fire extinguishing systems; and autopilot or stability augmentation systems.
The policy has the flexibility to accommodate the installation of new technology safety enhancements into Part 23, 27, and 29 aircraft that are determined to be a minor change to type design, FAA officials explained. The benefits must outweigh the risk.
The policy will reduce equipment costs by allowing the applicants the flexibility to select various industry standards that suit their product, as long as it meets the FAA’s minimum design requirements.
NORSEE approval under this policy is not an approval for installation on the aircraft – it just makes the equipment eligible for installation on the aircraft. There may be a situation in which installation of the equipment on the aircraft requires modifications that are considered a major change to type design, or major alteration to the aircraft. In these cases, the applicant is required to pursue the appropriate certification path (such as a supplemental type certificate), or field approval process, regardless of the “non-required” designation.
The FAA’s online list of approvals will be updated regularly.
