Quick Reference Handbook
A Quick Reference Handbook (QRH), sometimes called a cockpit operating manual or FCOM,[1] is a troubleshooting manual for aircraft pilots. A QRH is kept in the cockpit and can be consulted whenever the flight crew experiences in-flight problems. It includes various checklists for dealing with abnormal and emergency situations, based on the equipment and furnishings on the airplane. The aircraft manufacturer-designated checklists are always included in a QRH, and often the airline company or operator will include its own procedures. Therefore, there is no single universal QRH and they may differ widely in contents, but in practice, individual versions of it are referred to as the Quick Reference Handbook.[2] When designed and used correctly to address issues such as turbine engine failures or on-board fires, a QRH can prevent aviation accidents and incidents.[2]
Format
The first QEHs in the 20th century were made out of paper, but in the 21st century, many pilots have switched to so-called electronic flight bags, which have the advantage of electronic search functions, but require electricity to work.[2] Some modern aircraft such as the Airbus A330 have computerised some of the checklists, but other checklists cannot be properly programmed, because some problems cannot be correctly identified or diagnosed by aircraft computers; thus, the Quick Reference Handbook remains an essential tool for in-flight troubleshooting.[1]
Contents
One example of a checklist in a QHR is the Engine Failure/Fire – Severe Damage or Separation checklist.[1][3](3:02) Another example is the Cabin Altitude Warning or Rapid Depressurization checklist.[3](4:55)
