Abstract: A climatic heat aircraft protective (CHAP) screen that has been designed to protect various types of aircraft, and especially helicopters, from the adverse effects of direct exposure to sunlight while being relatively insensitive to wind conditions. The CHAP screen is specifically designed for various aircraft types to facilitate easy and rapid deployment and removal of the CHAP screen utilizing only the flight crew of the aircraft. The CHAP screen includes a porous screen canopy having overhanging portions and flap portions that are operative to reflect direct sunlight while allowing air to pass therethrough. The CHAP screen also includes a containment bag affixed to the underside of the porous screen canopy that is used to compactly stow the porous screen canopy prior to deployment and to secure the CHAP screen to the rotor head assembly of a helicopter during deployment.
