Airplanes undergo frequent inspections to assure that all parts and systems are functioning properly. One standard developed by ASTM International, a member and audited designator of the American National Standards Institute (ANSI), guides some of these inspections. ASTM F2696-08, Standard Practice for Inspection of Airplane Electrical Wiring Systems, covers basic inspection procedures for electrical wiring interconnect systems for normal and utility category aircraft.
This standard was developed by the International Organization for Standardization (ISO) Technical Committee (TC) 20, Aircraft and space vehicles, Subcommittee (SC) 9, Air cargo and ground equipment. The U.S. holds the leadership of this TC, and ANSI has delegated this responsibility to the Aerospace Industries Association (AIA), an ANSI member and accredited standards developer. James Rusty Rentsch is acting as the TC chairperson. The ANSI-accredited U.S. Technical Advisory Group (TAG) administrator is SAE International, an ANSI member and accredited standards developer.
Once customers have boarded, the air quality inside the cabin becomes paramount for the passengers' and flight crew's safety. SAE AIR 4766-2007, Air Quality for Commercial Aircraft Cabins, provides general information on air quality and references more detailed SAE resources on Environmental Control System (ECS), air quality contaminants, cabin pressurization, temperature, and humidity that affect the cabin environment. This standard was developed by SAE.
If an emergency should occur while passengers are on a plane, it is critical that all exits be clearly labeled and easy to find. Another standard by SAE, SAE ARP 488D-2000, Exits and Their Operation - Air Transport Cabin Emergency, suggests a system to make operation of the exits simple, quick, and obvious to all occupants under normal and emergency conditions.
While some planes may be grounded due to volcanic ash over the coming days, standards are in place to assure the safety and comfort of travelers when flights resume.
