## Abstract

These special conditions are issued for the Bombardier Model CL-600-2B16 airplanes, including variants CL-601-3A, CL-601-3R and CL- 604. This airplane, as modified by Atlantic Aero, Inc., will have a novel or unusual design feature associated with an advanced, enhanced flight vision system (EFVS). The EFVS consists of a head-up display (HUD) system modified to display forward-looking infrared (FLIR) imagery. The applicable airworthiness regulations 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.
