Confidential Aviation Safety Reporting to be Extended to Cover Bullying, Harassment, Discrimination and Victimisation.
From Wednesday 27th October, UK aviation’s Confidential Human factors Incident Reporting Programme (CHIRP) is to be extended to include reporting from commercial flight and cabin crews about bullying, harassment, discrimination and victimisation where the circumstances had, or could have had, a detrimental effect on flight safety.
The CAA has provided funding for this extension to CHIRP’s normal confidential reporting activities and, although the scheme will initially only be open to commercial flight crew and cabin crew, it will be expanded to cover the full range of aviation practitioners once initial lessons from the introductory programme are incorporated.

New aviation reporting portal
The aviation reporting portal relaunched for the UK on 5 January 2021.

CAA’s new Bowtie Risk Model Strategy
The CAA has published a new Bowtie Risk Model Strategy (CAP1329) which identifies how the models can be best used as an effective and proactive safety risk assessment tool. The overall aim is to inform and improve decision making so that the right actions can be taken to achieve the best safety outcomes for the UK public.
The strategy’s objectives are linked to Performance Based Regulation (PBR), Safety Management Systems (SMS), issuance of approvals, obtaining safety assurance and collaborating with the aviation industry. More bowtie information is available on our website:

Dangerous Goods Radiation Protection Programme
The transport of radioactive material as cargo must be subject to a Radiation Protection Programme (RPP), which must consist of systematic arrangements aimed at providing adequate consideration of radiation protection measures.
Operators that hold a dangerous goods approval and permit the transport of radioactive material should identify their RPP document reference and location within their Operations Manual, Part A, Section 9. The specimen operations manual entries published on the CAA website have been updated to refer to the need for an RPP.

AOC holders should draft amendments to their operations manual to include a reference to their RPP and send to [email protected] with a completed form SRG 1832.

Winter Operations 2019 / 2020
During Winter 2018 / 2019 de-icing MOR data showed primary error factors as 65% ramp services and 30% aerodrome. Of these errors 70% were detected by the pilot, 14% by ground crew, and 11% by cabin crew.
Considerations when preparing for Winter operations:
Sources of information to use, particularly for hold-over times
Specific issues associated with your operation and aircraft
– Permitted contamination
– Permitted fluids
– Refreezing of some fluids
– Effects on aircraft of runway / taxiway de-icing substances
– Contaminated runway performance
Updating documentation / Operations Manuals
Training / retraining staff
Serviceability of de-icing / anti-icing equipment
Service level agreements
Snow plans at aerodromes used
Using your SMS to evaluate Winter Operations
