Aviation wheel chocks are found in National Transportation Safety Board (NTSB) - Aviation Branch in the Aviation Coding Manual last updated in December 1998.These chocks have found their way into numerous safety organizations across the US, including OSHA for shipping guidelines, the MSHA for mining and the NFPA for fire fighting safety.
About the NTSB Coding Manual
NTSB is the arm of the US government responsible for maintaining the standards of the US aviation industry. The coding manual, much like other manuals incorporated into non-private organizations the agent responsible for defining safety globe workplace, is comprehensive and provides codes for describing each and every of accidents. The codes are fed into a mainframe computer to analyze the accident. In the document, instructions for utilizing the codes allotted to the various aspects of aviation, definitions which includes worksheet are put in. Codes for the events of what happened follow that, when using the phases of operation next, and finally codes for causes, factors and other events - which is where the chocks are named. Aviation chocks fall under code 17126 all of the NTSB Coding Manual, under Section IA, Miscellaneous aircraft/equipment subjects. The document is comprehensive in nature, but relatively easy to discover what is being searched.
The Importance of Wheel Chocks in Aviation
Any rolling vehicle is a hazard, but an airplane can be particularly hazardous because it's much heavier and better likely to do damage than a pedestrian truck or vehicle. A single pilot can run a chock when it is on his involving required items when he lands, and as soon as the plane is a military or cargo aircraft, the pilot will have to depend on they to place the aviation chocks to secure it from rolling.
Chocking Basics
Aviation wheel chocks work the comparable to chocks used in mining, construction, shipping or other industry. The airplane must be stopped and you can turned off, along with the chocks must be fit snugly to the tire and leading on which it's sitting. The chocks should also be tested with the aircraft before use, and if the payload changes, adjusting the chock in a position to necessary. Made from impact-resistant urethane, they are FOD free, that is foreign object damage free and won't rot or split as the old-fashioned wooden chocks of the past did. They are not only found resistant to lubricants and fuels, are usually lightweight and easy to move around, even with their high load-bearing capacity.
Aviation chocks need to be carefully considered and used, to uphold expectations for safety established by the NTSB.
