On average, half of a 24 hour day is darkness. Military flight operations do not stop during hours of darkness, and use of night vision goggles to facilitate such operations is widespread. For best visual acuity of the intensified outside scene, aircraft cockpit lighting must be compatible with (not be sensed or intensified by) a night vision imaging system (NVIS). Multiple methods of providing NVIS compatible cockpit lighting exist. With two exceptions, the current lighting methods are designed for permanent installation. Descriptions of each of the methods are provided. Several recent mishaps and near-mishaps have occurred at night in which cockpits were temporarily illuminated with chemical light sticks. As a result of multiple inquiries and concerns about the quality of illumination provided by chemical light sticks, a new interim night vision compatible illumination system based on light emitting diodes (LEDs) was developed by Raytheon Systems at the Air Force Research Laboratory (AFRL/HEA) at Mesa, AZ. The LED system provides illumination complying with MILSPEC requirements and is intended for temporary installation. A description of the system is given.
