xList. The future starts NOW

rEvolution is here.
xList is a new concept for the Electronic Flight Bag.
xList is a powerful communication system integrated within the best electronic checklist.

Attention, version 4.1 is current.
For a fresh installation go to:
iPad settings->General->Storage & Icloud-> Manage storage and delete xList there before installing the new version.
xList allows users to upload their own utilities, procedures and attention crews documents.
Use this page to store your files in our server, after go to xList Library and add the new document.
Note: Attention Crews update is automatic when autoupdate is set ON.

Adaptable to any airplane, airline, designed to be part of the EFB Electronic Flight Bag.
xList is the best checklist solution:

xList is a powerfull communication center between Airline and cockpit

Flow schema

xList establish a real time link between all the actors involved in the flight.
Flight dispatch, Operations, Training and the more relevant departments presence in the cockpit, is now possible through a simple system of documents connected via internet.
xList links pilot/plane/company using internet at no cost, allowing the reception of operative flight information from the dispatchers in real time.
It is designed focused in safety and economy operation, geared to pilots and aerial companies.

- Talking checklists error proof. 
- Interactive company briefing system allowing images, video and color coded messages (aeronautical red, yellow and green).
- New age documents view, using color, graphics, images and flow paths.
- Useful technical info view to assist during the flight. No stress in busiests moments.
- Emergency view for immediate access in the worst scenary, where pilots more need it.
- EASA type A EFB document.

xList is the result of many years of experience and its design its derived from real flight. It is a powerful tool for the pilots. A number of auxiliary views are designed to assist the pilot on preparing every phase of the flight in a precise and standard manner, making it easy as ever. Procedures are just a click away at full technology power, using visual flows, image or sound and colors. Tables and the more frequent related data are concentrated now in an utility view together with a calculator

For the company, earnings are immediate. No expensive printing and distributing to a fleet constantly moving. All the documents are easily changed by the assigned company department with our favourite text software and can be updated in seconds from production to the Ipad final destination. The improvement in safety and standarization is clearly remarkable from its first use. Co-authoring permits differents departments, like training and OPS, introduce its related modifications with total independency.

xList has been created by high experience pilots, not for profit or commercial benefits. With the firm conviction that is the best future for us.

xList here shown is an Airbus standard for an A340-300/500 version.
xList can be quickly tailored to any company any fleet.


Each time xList is started:
- All the checklists are reset to initial state.
- A flight recorder file is stored in the Ipad (.txt type and current date as file name).

The initial xList view consist of the normal checklist headers ordered by flight phase sequence and colored indicating the list type. Green normal, light green for “below the line” checklists.
That is Airbus xList format. Different airplanes have different color codes for read, silent or read and do checklists.

Checking the list and the items can only be performed in strict sequential order to avoid check marking items not completed yet.
Tapping over the NEXT correspondent list header, the checklist will expand at the top of the view, the iPad will read aloud the name of the checklist and a register will be recorded in the xList flight recorder with the name of the list, the actual time and the GPS position.
Tapping over ANY (but not the next in sequence) list header, the checklist expands showing all its items. Tap again will collapse the list to its previous state.

Tapping over the next in sequence list item will dimm it gray adding a checkmark.
Items can be unchecked but an item can only be checked in sequential order, i.e. if the previous is already checked.
Once we have completed any checklist the list header turns grey with no further color reversion posible, for error avoidance, the Ipad reads aloud the name of the checklist adding “Completed”, the checklist will be collapsed and the next checklist will be positioned ready on top of the screen.
A record with the name of the checklist, the time and the GPS position, is then written in the flight recorder.

There is a convenient switch located above the checklists labelled PF. Above this switch a label specify the role of the iPad user ->Crew Member 1 (Captain)/ Crew Memeber 2 (F/O). This setting can be set in the xList settings within iPad settings. Through those two swtiches we tell to xList to adjust the checklist state to the role of the user i.e. CM1 & PF. The purpoise is to mark as checked (grey color) the checklist that will be performed by the other pilot avoiiding having to checkmark all the already marked items when changing from ground roles to flight roles. Those roles are tipically assigned by the company SOPS thus different airline/fleet settings will have different assigns.

The checklists are tailored to every customer. Go to iPad settings -> xListA340 settings and select your airline and fleet to change to different Checklists.


Located at the bottom of the checklists view there is a menu with 4 buttons.
Two are links to auxiliary documents views (Att. Crews, & Library).
One drives to an aeronautical calculator (Calculator).
One goes to the historical records view (Flights).


The revolution starts here.
Behind a simple checklist resides a whole integrated system of information in real time. Checklist is one of the more reviewed cockpit documents that is why is we store here information of first level of relevance.

The Attention Crews document aims to serve as a source of constant updated information where maintenance, flight operations and ground operations communicate among themselves and with the flight crew.
Every iPad will receive its unique document. This is achieved by storing a simple Word document in the company server. Select the name of that document in the iPad settings and it will download it.
Let say we use the EC-INO.doc.
The EC-INO.doc document will be hosted in the server of the company easily accessible from any Department. The document should be clearly divided (by use of colors, tables, pages or any other means) into as many areas as departments will use it. and divided into three (or more) areas clearly differentiated by colors or any other means. Every department will store in its correspondent area permanent information related to that particular plane and flight. Any change in the word document will be instantly received in the plane and the pilots will be notified.

For example, there is a hurricane in the area of the next flight for the EC-INO and Flights Dispatch wants to send the crew the latest satellite image or a link to a web page with important information. It can be done here. You could send it to the iPad email but it may be unnoticed among other emails. But if the xList warns that there is new information it will have the maximum level of efficiency. No need to search in the mailing list what concerns us and which not.

For example maintenance would like to inform you that number 4 engine may have EGT over limit but it is preferable to perform normal start instead of manual start. Or that since the engine number 3 is about to enter in overhault but burns too much oil, it has provided a box of oil cans in the bulk in case should be necessary to refill in any scale. Maint access to the att.crew document on the server and it will be immediately received by the iPads.

The Attention Crews document is the only auxiliary documents that allows same capabilities than a web browser, like browse web pages, send data or viewing video and audio. This document permits to interact with the crew being the first step to introduce a real time internal chat.

You may refer the crew to a web page where the pilot must click on the "message received and understood" box or send you back any specific info. An immediate example would be a page where the pilot and Flight Dispatch maintain direct chat on the estimated departure delay and received slots.



Pilots we need to check many parameters and data from different documents and places
It takes vital time to us consult always the same tables and charts just in very short time.
This view has a calculator for the most often used in flight parameters.


Cockpit is always full of paper charts and tables. At the time the document is needed pilots we must locate the document which very often is not in its proper place. Above that paper documents are very close to its end, because the production/distribution costs and the limited resources they offer.
EFB opens a new world of possibilities with new age documents that may include video, audio, color text, with all the facilities like zooming, fast scrolling and searching, limited only by the imagination. And all this only at a finger tap of distance for the pilot and a click to the OPS airline departments to distribute at no cost.

LIBRARY view contains a list of documents defined by OPS to assist in various flight phases.
The list is divided in three main subjects allowing its sequential order of importance:
Emergency, Procedures and utilities.

Each cell in the list contains the title of the document, the name of the document file stored in the company server, the date of the iPad document its size and the date of the remote document stored in the company server. Tapping over the cell its correspondent document will appear in a different view.

When the Library view comes to screen the iPad will connect the server and check all the documents included in the list. When a change is detected a green button labeled "UPDATE" will be shown to allow the user to download the latest document version. When the UPDATE button is tapped a FMS will appear on top of the list to download the file from the server.
To add a document to the list tap over the ADD button and a new cell will be created with the title and filename of "New Document". Once we wrtie down the name of the file the iPad will connect the server and if the document is found the UPDATE button will be shown.
To delete any document from the list, slide the finger right to left over its cell and a DELETE button will be revealed.
These documents can be PDF (recommended by size, fast loading and easy production), MSWord, Apple pages, OpenOffice, html or many other different formats. It may include all kind of information like simple tables (for example Delay Codes) to sofisticated videos, high quality images and links to web interactive sites.
Aviation is now heading to the use of new technologies in pursuit of more advanced documentation, much more effective and precise. Interaction is now becoming a standard and manuals are updated more frequently than ever thanks to the economy and immediate of the electronic documents.
Company's training management can help to cockpit standardization through this document extracting the manufacturer manuals and incorporating the company policies into a graphic view for fast and frequent consultation of normal procedures.
The document is downloaded from the company servers as frequently as needed through the updates view and is stored in the iPad for off line use.


xList settings is a useful feature. As the iPad may change, from left to right seat and different airplanes, settings is used to tell the app what airplane and the pilot seat:
- CM1 switch ON for the Captain, OFF for the F/O.
- Attention Crews. It will discriminate from one plane to other of the same fleet. i.e. Setting D-FBW.pdf will receive only the notifications and Attention Crews docs for that particular plane. That is made so by assigning the same name document in the company server as the airplane registration.
- Airline fleet is to select the correspondent fleet checklist. We may have as many different checklists as airplanes models and variants coexisting in the company.
- AutoUpdate ON (default) will automatically download any change made on the Attention Crews document and stored on the server. Position OFF will require the user intervention showing the FMS with the UPDATE option to be done manually.

Location services needs to be activated in order to record the position of the plane at the start and completion of every checklist.

Flight recorder

Every time xList is launched a file named as the current date and time, is created.
When the correspondent checklist is expanded, a text line with the name of the list and the time is recorded.
When the checklist is completed a new text line is added with the time and the GPS position.
All these files are permanent stored in the iPad and can be revised in this view.
There is a button to delete all the files except the current in use.
