First read the article [[Writing a SKYbrary Article]. This article is intended as a deeper and more pragmatic discussion regarding writing conventions, the structure of articles and some tips and example code that will be useful when writing SKYbrary articles.

Article Title

If the title of an article is to include a commonly recognised abbreviation, always include the full name and add the abbreviation in brackets afterwards, e.g. Instrument Landing System (ILS).

The title of an article should reflect the terminology in use in Europe. Differences in terms between North America and Europe/Rest of World are addressed by ensuring that the North American terms are referred to in the body of the text - this way they will be picked up by search engines. For example take a look at the article on Level Bust; in this case the North American term is highlighted at the top of the article in a larger font like this:

Altitude Deviation

This isn't absolutely necessary - the important thing is to endsure that alternative recognised terminology is referred to at some ;point in the main body text, usually within the Description.

Article Structure

Articles addressing an operational risk should conform to the same generic layout as shown in the exemplar article on Jet Stream. For other articles however, this may not be appropriate. In such cases, the article should always start with a Definition and/or a Description in which you explain what the article is about and also, where appropriate, what it is not about. The main body should then be structured in a logical way finishing with Related Articles (internal links) and Further Reading (external links and Bookshelf items).

Style and Language

SKYbrary articles are closer to an Encyclopaedia entry than a magazine article. The article must avoid references to future events as this makes the article look dated when viewed after those events have taken place. Article are written in UK English.

Accidents and Incidents

Any use of a previous accident or incident, to illustrate a safety point, must link to an existing event in SKYbrary's A&I event database. If the perfect illustration of a safety issue is an event currently not included in the database then a request should be made to the Content Manager to have the event included in the Database (this could take 3 months).

It is often very useful to include a dynamic query that will list all events in the SKYbrary A&I database that are tagged with a relevant tag. e.g. a list of all events that tagged as Overrun on Take Off

  • B773, Auckland Airport New Zealand, 2007 (On 22 March 2007, an Emirates Boeing 777-300ER, started its take-off on runway 05 Right at Auckland International Airport bound for Sydney. The pilots misunderstood that the runway length had been reduced during a period of runway works and started their take-off with less engine thrust and flap than were required. During the take-off they saw work vehicles in the distance on the runway and, realising something was amiss, immediately applied full engine thrust and got airborne within the available runway length and cleared the work vehicles by about 28 metres.)
  • A320, Basel-Mulhouse-Freiburg France, 2014 (On 6 October 2014, an A320 crew requested, accepted and commenced an intersection takeoff at Basel using reduced thrust performance data based on the originally anticipated full length takeoff which would have given 65% more TODA. Recognition of the error and application of TOGA allowed the aircraft to get airborne just before the runway end but the Investigation found that a rejected take off from high speed would have resulted in an overrun and noted that despite changes to crew procedures after a similar event involving the same operator a year earlier, the relevant procedures were still conducive to error.)
  • CRJ1, Lexington KY USA, 2006 (On 27 August 2006, a Bombardier CRJ100 cleared for a night take off from runway 22 instead began take off on unlit runway 26. It was too short and the aircraft ran off the end at speed and was destroyed by the subsequent impact and post-crash fire with the deaths of 49 of the 50 occupants - the First Officer surviving with serious injuries. The Investigation found that the actions of the flight crew had caused the accident but noted that insufficiently robust ATC procedures had been contributory and the effects of an ongoing runway extension project had been relevant.)

A lists of events that accompany each Category e.g. Accident and Serious Incident Reports: AW is an easy source of the code needed to set up a query. More sophisticated queries are possible e.g. that show a particular kind of event that occurred in a specific phase of flight.


Images on SKYbrary are presented in the following way:

When uploading images, ensure that the size of the image is below 1mb in size.


Constructing tables is complex and takes a certain amount of patience. Here is an example of a tables whose code can be used as a template:
