When the idea of checklists began, its success enabled aviation engineering to become more complex. As systems and procedures became more sophisticated, checklists were extended from the normal 4 phases (take off, in-flight, before landing and after landing), to almost every abnormal situations or emergencies that may happen.

Over the years, the tendency for mistakes and errors to occur increased partially due to the numerous amounts of checklists developed and the lack of exposure of a pilot to these abnormal circumstances and emergency situations. Checklists became a focal and controversial subject on the “how it can be improved” spectrum from methodology and technique to design, colours, font, devices, human factors etc.

Common issues tend to appear when it comes to handling appropriately abnormal and emergency situations, as humans react differently under pressure, stress, ambiguity or high workload. Because of this, CHECKL!ST has developed and added 2 essential features to reduce risk and assist the pilot in these situations.


The major purpose of aircrafts checklists is to ensure that the pilot and crew properly configure the airplane for any phases of flights, without omission and in an orderly manner. The actual first standard definition was: "The major function of the checklist is to ensure the crew will properly configure the plane for flight, and maintain this level of quality throughout the flight, and in every flight"

They are categorized into two types of checklist:

· Normal checklist: considered as a Challenge-and-Response checklist, following procedures done by memory for each phases of flight.

o Provides cross checking, dictates duties (multi-crew)

o Serves as quality control (airlines management/government regulators)

o Enhance team concept by distributing the workload and keeping all crews in the loop (multi-crew)

o Provides systematic & convenient eye scan,

· Non-normal checklist (Abnormal & Emergency): Considered as Read-and-do checklist, they include pre-conditions/aircraft status for which they must be assessed first. In some cases it is a combination of Challenge-and-Response and Read-and-do, mostly for emergencies, in which memory items are involved, since some items are time critical and must be performed immediately.


Emergency and abnormal checklists are essential tools pilots use to respond timely, orderly and appropriately to unusual or critical situations. Those situation, by definition, rarely occur, therefore the approach from the pilot is crucial to the safety of a flight.

These checklists contain essential steps for the particular emergency or abnormal condition. And most emergency situations require timely action.


· Often time critical, complex or ambiguous

· High stress, high workload, and a great outcome may be at stake

· Require high level of coordination

Procedures & Checklists

· Generally focused on aircraft systems rather than on the situation as a whole

· Practiced seldom and used rarely

· Often highly dependent on fragile cognitive processes

· When needed, are crucial and must be performed correctly


Various methods have been experimented to improve the response of pilots towards unusual situations and their ability to follow a sequential step of actions while being under stress, high workload, pressure and often with time constraints.

In recent years, electronic checklists proved its efficiency and are now incorporated with modern aircrafts. This is what we bring on board with our Checkl!st app, regardless of the type of aircraft you operate. To help you cope with any situation you might encounter, whether you are being under strict time constraints, have doubts on which checklist to perform or simply having difficulties retrieving a checklist, we’ve added 2 essential features:


Throughout the various phases of your flight, we incorporated links in your normal checklists that will redirect you to the common related emergency that could occur. It will allow you to carry them out without losing time having to search for them.

With just a quick click, you have access to a few options associated to the possible failure.

They are constantly located at the bottom of your checklist, and a simple tap will allow you to start carrying it out. If multiple emergencies are available, a quick tap will display them all. This simple, effective and time saving tool can assist you out of any critical situation.


In various checklists, (normal, abnormal or emergency), depending on the pre-conditions of the aircraft status, systems or environment, one or more succeeding checklists will have to be carried out. However, it is often confusing for the pilot/crew to decide which checklist to go for, leading to added time spent on the task and mistakes can occur.

Because of this, we added an Item interlink feature, wherein in these scenarios, will highlight instantly the appropriate succeeding checklist and dim the other ones, scrupulously following the guidance from the operating manual provided by the manufacturer. It will also consider the active checklist completed ONLY once these succeeding checklists have been accomplished.

No more confusion, no more doubts, no waste of time, this simple tool will enhance your performance in handling any emergency situations.

More detailed information on these features is explained in our User’s manual. Stop wasting previous time scrolling pages to find your checklist and be a part of the development. Join in on the electronic checklist world.
