Quick Reference Handbook
From Wikipedia, the free encyclopedia
A Quick Reference Handbook (QRH) is a quick-access manual for aircraft pilots that contains all the procedures applicable for non-normal and emergency conditions in an easy-to-use format. Performance data corrections are also provided for specific conditions.[1][2] A QRH is kept in the cockpit and can be consulted whenever the flight crew experiences in-flight problems.
The first QRHs in the 20th century were made out of paper, but in the 21st century, many pilots have switched to so-called electronic flight bags (EFB), which have the advantage of electronic search functions, but require electricity to work.[3] Some modern aircraft such as the Airbus A350, and Airbus A380, have computerised some of the checklists with their own integrated EFB. However, pilots still are required to have their own EFB as an added redundency as not all procedures and use cases will display the correct checklists, due to some problems being unable to be correctly identified or diagnosed by the onboard aircraft computers. Thus, the Quick Reference Handbook remains an essential in-flight tool for the crew.[2]
