What is QRH in Aviation? (Quick Reference Handbook)

Updated: March 02, 2024

What is a Quick Reference Handbook (QRH)?

A Quick Reference Handbook (QRH) is a vital tool used in aviation. It is a concise and easy-to-use manual that provides pilots with immediate access to critical information during flight operations. The QRH is designed to assist pilots in handling abnormal and emergency situations by providing step-by-step procedures, checklists, and performance data. It serves as a quick and reliable reference guide, allowing pilots to respond swiftly and effectively in challenging situations.

The QRH is an essential component of an aircraft's documentation and is typically carried on board every flight. It is specifically tailored to the aircraft model and includes information specific to that aircraft's systems, procedures, and limitations. This ensures that pilots have the necessary guidance and information relevant to their particular aircraft.

The Importance of the Quick Reference Handbook

The Quick Reference Handbook plays a crucial role in aviation safety. It provides pilots with a standardized and organized set of procedures to follow during abnormal situations, such as engine failure, fire, or loss of pressurization. By having the QRH readily available, pilots can quickly access the appropriate checklist and execute the necessary actions in a timely manner.

The QRH also serves as a valuable training resource. Pilots undergo extensive training on emergency procedures and abnormal situations, and the QRH aids in reinforcing that training. By familiarizing themselves with the contents of the QRH, pilots can enhance their preparedness and confidence in handling unexpected events.

Furthermore, the QRH contributes to effective crew coordination. In a high-stress situation, clear communication and coordination among the flight crew are essential. The QRH provides a standardized set of procedures that all crew members can refer to, ensuring everyone is on the same page and working together towards a safe resolution.

Contents of a Quick Reference Handbook

The specific contents of a Quick Reference Handbook may vary depending on the aircraft model and airline, but there are several key elements commonly found in most QRHs. These include:

Abnormal and Emergency Procedures: The QRH provides step-by-step checklists for various abnormal and emergency situations, such as engine failures, electrical malfunctions, or hydraulic system failures. These procedures guide pilots through the necessary actions to be taken to mitigate the situation.
Performance Data: The QRH includes performance charts and tables that assist pilots in calculating critical parameters during abnormal situations, such as landing distances, climb gradients, or fuel consumption. This information helps pilots make informed decisions and select the most appropriate course of action.
Systems and Limitations: The QRH contains detailed information about the aircraft's systems, including limitations, normal operating procedures, and abnormal indications. This allows pilots to quickly reference relevant information and understand the implications of specific system failures or malfunctions.
Emergency Evacuation Procedures: In the event of an emergency landing or evacuation, the QRH provides guidance on evacuation procedures, including the use of emergency exits, evacuation slides, and communication protocols.

It is important to note that the QRH is not a comprehensive flight manual. It focuses primarily on abnormal and emergency procedures, providing concise and easily accessible information for critical situations. Pilots also rely on other manuals, such as the Aircraft Flight Manual (AFM) or Pilot Operating Handbook (POH), for normal operations and general reference.

Aviation authorities, aircraft manufacturers, and airlines ensure that the information contained in the QRH is accurate and up to date. Regular revisions and updates are made to incorporate any changes in procedures, systems, or regulations. Pilots must ensure they have the latest version of the QRH for their aircraft model and review it regularly to maintain proficiency.

In conclusion, the Quick Reference Handbook is an indispensable tool for pilots in the aviation industry. It provides them with immediate access to critical information, procedures, and performance data during abnormal and emergency situations. The QRH enhances flight safety, aids in training, and facilitates effective crew coordination. Pilots must familiarize themselves with the contents of the QRH and regularly update their knowledge to ensure preparedness and proficiency in handling unexpected events.
