CHIRP Aviation

CHIRP Aviation The aim of CHIRP is to contribute to the enhancement of aviation safety in the UK and worldwide. CHIRP has been in operation for aviation since 1982.

In 1996 the Programme was restructured in the form of a charitable company limited by guarantee to enable it to make a more effective contribution to the resolution of important safety-related issues. This corporate structure was selected in order to provide a totally independent organisation, with management and fiscal responsibilities held by an Independent Board of Trustees. The Maritime programme has been operating since July 2003. CHIRP welcomes safety-related reports from flight crew, air traffic control officers, licensed aircraft maintenance engineers, cabin crew and the General Aviation community and people in the international maritime sector, including the shipping industry, fishing industry and leisure users. Reporters' identities are kept confidential. Personal details are not retained and are returned to the reporter or destroyed on closure of their report. The information provided is made available, with the approval of the reporter and in a disidentified form to those who can take action to remedy the problem. Important information gained through reports; after being disidentified, is also made as widely available as possible principally through the publication of FEEDBACK with the aim of improving safety standards. The CHIRP Aviation programme compliments the Civil Aviation Authority Mandatory Occurrence Reporting scheme. Both Aviation and Maritime programmes also compliment other formal reporting systems operated by many UK organisations, by providing a means by which individuals are able to raise issues of concern without being identified to their peer group, management, or the Regulatory Authority. Anonymous reports are not normally acted upon as they cannot be validated.

"Almost every significant improvement in aviation safety has started with somebody noticing something wasn’t quite right and deciding that it was worth telling someone else about it."

Mike O'Donoghue, CHIRP's new General Aviation Programme Manager and former Chief Executive of the General Aviation Safety Council (GASCo), discusses why every report matters in General Aviation FEEDBACK 109, Learning Through Experience.

A checkout flight in an unfamiliar aircraft nearly ended in a collision with raised runway lights. The instructor intervened as the aircraft drifted during take-off.

CHIRP’s report shows how changes in control feel, workload and the airfield environment can narrow the margin for error. It also shows the value of speaking openly about a close call.

Following CHIRP report DUAS0049 (see below), we thought it might be helpful to provide some resources. Drones are becoming ever more popular but those buying a drone off the shelf may be unaware of how to fly their new drone safely and responsibly.

In the report, a new drone operator realises that they had been straying into the edge of an airport no-fly zone. To avoid this kind of risk, the links below can be used to find helpful guidance and flight planning information.

If you are a new drone operator remember that you must follow the Civil Aviation Authority's guidance.

The calculations had been checked. The take-off looked possible.

A newly qualified pilot taking her family flying found herself running out of runway, with too little speed to take off safely.

Expecting slower acceleration, she initially accepted what she was feeling. By the time the danger became clear, her options were severely limited.

This first-hand account explores how a small administrative error can have serious consequences and why questioning expectations, speaking up and sharing experience matter for safety.

What happens when pressure to meet turnaround and service targets affects cabin crew’s ability to prioritise safety?

In this CHIRP report, a flight crew member raises concerns about mounting pressure on cabin crew colleagues and its impact on wellbeing and safety. Pressure remains among the top five issues reported to CHIRP’s cabin crew programme.

Cabin crew need time, support and confidence to carry out their safety responsibilities. A just culture will mean they feel able to raise concerns about fatigue or workload. Open communication between flight crew and cabin crew is essential.

Removing a hazard is stronger than reminding someone not to miss it.

Leaving a towbar attached may be operationally convenient, but it creates a hazard the control of which eventually depends on someone remembering that it is there; despite interruptions, changes to routine or time pressure. A checklist helps, but it does not make memory infallible.

The human-factors question is not only: “Why didn’t the pilot notice?”

It is also: “Why was the system designed so that one missed cue could be highly consequential?"

Removing unnecessary equipment, making it conspicuous or assigning positive ownership reduces reliance on perfect recall.

Which hazards in your operation are controlled mainly by “remember to…”?

Is your turnaround data measuring the operation, or changing it?

A CHIRP Aviation report raises an interesting human-factors question about on-time performance, safety duties and delay coding.

Metrics do not simply describe work. When a metric carries consequences for individuals or teams, it can influence how people prioritise tasks. And how they record what happened.

If staff feel that delay data allocates blame, the organisation may receive a tidier account of the turnaround, but a less accurate picture of work as done.

Good operational data depends on people being able to explain delay without becoming the delay.

Does your delay-coding process identify causes or assign ownership?
