ВОЗДЕЙСТВИЕ ПОРТАТИВНЫХ ЭЛЕКТРОННЫХ УСТРОЙСТВ НА БОРТОВОЕ ОБОРУДОВАНИЕ ВОЗДУШНОГО СУДНА

Abstract

The article is devoted to the topical problem of analyzing the risks that arise during the operationof aircraft in cases where portable electronic devices are on board the aircraft, and thechoice of methods for checking the resistance of onboard equipment to the effects of such devices.The article considers all possible ways of propagation of spurious and intentional emissions fromportable electronic devices to avionics systems and analyzes two main aspects of the impact ofportable electronic devices on aircraft avionics. The first aspect defines the aircraft system andqualification guidelines for radio-exposed equipment that provide immunity to radio emissionsfrom intentionally transmitting portable electronic devices. This is usually interpreted as protectionagainst the impact of portable electronic devices "through the back door." The second aspectdefines acceptable interference that causes bandwidth loss between aircraft radios and spuriousportable electronic devices. This is commonly referred to as "front door" protection against portabledevices. Based on an analysis of the main risks associated with interference from portableelectronic devices to aircraft systems, aircraft systems have been identified for which a demonstrationof compliance with the resistance to the effects of portable electronic devices must be performed.In order to demonstrate the suitability of the front door immunity of aircraft equipment, itis necessary to assess the levels of possible interference from portable electronic devices in thereception band of aircraft equipment. Demonstrating the compliance of aircraft equipment for“through the back door” exposure is similar to demonstrating resistance to high-intensity electromagneticfields and indirect lightning strikes. It is necessary to perform one of the two proposedmethods to establish their susceptibility to radio emission and control levels of the susceptibility ofaircraft systems to radio emission. The first method is related to the delivery of equipment to thetest bench for RF emissions, the second method is to test the systems that are installed on the applicableaircraft. Recommendations have been developed on the choice of methods for verifyingthe resistance of aircraft systems to the impact of portable devices. The impact aspects analyzedwill help determine the scope and methodology for conducting tests to remove restrictions on theuse of portable electronic devices on board aircraft.
