Why should I, as a DOA holder designing changes to rotorcraft, know about Night Vision Imaging Systems (NVIS)?
In the last years the use of night vision systems in civil operation increased, reflected in an increasing number of rotorcraft already equipped with the system or 'NVIS-friendly' (with provisions for installation of NVIS systems).
Awareness of the NVIS technical field is expected from any DOA holder – so that it can assess if it’s design changes are (potentially) affecting the NVIS characteristics of the rotorcraft.
For DOA holders who design changes that are affecting NVIS, this technical field must be included in the Terms of Approval.
