QuickReference Handbook (QRH) in Flight Operations

Inflight operations, a quick reference handbook is defined as aproblem-solving tool which has specific guidelines or indications.Such signals range from annunciator lights, multifunctional displayedmessages or even warning lights. In some cases, the issue could beexposed due to the presence of electrical smoke or fumes [ CITATION Sky16 l 1033 ].In any similar event, a specific occurrence must have happened, andthis is where the QRH comes into use. A prescribed format can befollowed as outlined to ensure that the indication has beenidentified based on a checklist. The handbook also goes further todescribe the characteristics of what has happened in an overviewmanner, followed by the repetition of memory items and the strategicsteps to be taken. Notably, this tool utilizes the “if, then” and“if not” formats of choice and action hence giving a lead to thenext step.

Agood example is that of fuel pump failure. In such a scenario, themultifunctional display will give a message concerning the failure,then describes what has happened. The guideline will also give awarning obtained from the initial operational manual prompting not toreset fuel pump circuit breakers. Further instructions couldrecommend pressing illuminated light to turn it off. Likewise, ifnone of the pump lights are illuminated, one might need to go to thenext step. Apparently, a QRH checklist is used in such a way. Thedevelopers design it to be as straightforward and direct as much aspossible [ CITATION Aus111 l 1033 ].By making it so, a member of the cabin crew can locate it quickly,read, comprehend and thus apply the steps without the need forbackup, external assistance or verification.

QRHsare developed for the various aircraft that exist and for bestoutcomes, one might need to fly on autopilot so as to have the timeand space to find and implement the checklist. Take for instance anincident of engine fire during flight. The following can be the QRHprocedure:

Turnof fuel selector, the idle cut-off for mixture, prop feather, pullair shutoff control, turn off fuel boost pump, switch off magneto,turn off the alternator, keep oxygen as required, turn off aircondition and land as soon as possible [ CITATION Don11 l 1033 ].

Oneimportant function of the QRH is that it gives the order ofaccomplishments based on priority from the most critical to the lesscritical. Working using memory may not always yield similar or betterresults. For instance, in the case of an engine fire, one might shutdown the engine and confusion sets in on what to do next. The QRHcomes in handy by providing what to do and in which order. Once safelanding is attained, the manual can be analyzed to identify the causeof the problem. It is important to note that when up in the air itis best to consider doing the right thing only. Lastly, having a wellprepared QRH ensures that mistakes do not take place. The way to gois to calm down and proceed with the appropriate step.

Afew memory pieces are required to take critical and immediate actionto prevent catastrophic occurrences. After initiating the key memoryitems which are few, the only thing remaining for a crew member is toconsult the QRH. All in all, a combination of memory and QRHprotocols are all necessary, but the QRH is one of the mostsignificant tools to supplement the achievement process and increasethe chances of safe landing in case of an incident.
