A Quick Reference Handbook (QRH) is an aircraft
technical document – quick-access
manual for
aircraft pilot
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators, because they ...
s that contains all the procedures applicable for non-normal and emergency conditions in an easy-to-use format. In addition, performance data corrections are also provided for specific conditions.
A QRH is kept in the
cockpit and can be consulted whenever the
flight crew experiences in-flight problems.
Format
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 bag
An electronic flight bag (EFB) is an electronic information management device that helps flight crews perform flight management tasks more easily and efficiently with less paper providing the reference material often found in the pilot's carry- ...

Some modern aircraft such as the
Airbus A330
The Airbus A330 is a wide-body aircraft developed and produced by Airbus.
Airbus conceived several derivatives of the A300, its first airliner in the mid-1970s. Then the company began development on the A330 twinjet in parallel with the A3 ...
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 in-flight tool for the crew.

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.
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
An aviation accident is defined by the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft, which takes place from the time any person boards the aircraft with the ''intention of f ...

QRH have to include time-critical information and frequently used information for the flight crew.
One example of a checklist in a QHR is the Engine Failure/Fire – Severe Damage or Separation checklist.
Another example is the Cabin Altitude Warning or Rapid Depressurization checklist.
