## Abstract

These special conditions are issued for the Bombardier Model CL-600-2B16 (CL-605) airplane. This airplane, as modified by Rockwell Collins Aerospace & Electronics, Inc., will have an Enhanced Flight Vision System (EFVS). The EFVS is a novel or unusual design feature which consists of a head-up display (HUD) system modified to display forward-looking infrared (FLIR) radar imagery. The airworthiness regulations applicable to pilot compartment view do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
