In May 2022, an Airbus A320 approaching Paris Charles de Gaulle airport was given an incorrect altimeter pressure setting, which caused the barometric altimeters on board to show that the aircraft was nearly 300 feet higher above the ground than it actually was.The crew were unaware of the problem and didn't see the runway because of bad weather. They carried out what they believed was a normal go around and never realized that they came within six feet of hitting the ground.In this episode we talk to aviation experts at the UK CAA and NATS to get their perspectives on what happened, the risks involved and the safety guidance in this area.

How do airports manage the risk of runway incursions? We talk to Heathrow Airport’s Head of Airside Operations Trevor Waldock about causal factors that can lead to an incursion and some of the safeguards that are in place to prevent them.You’ll hear about the safety guidance and procedures that are followed at airports and the importance of a ‘just culture’ where everyone is encouraged to report safety concerns and incidents. We also discuss the challenges of working through and emerging from the COVID-19 pandemic.Guidance and resources related to this episode:European Action Plan for the Prevention of Runway Incursions (EAPPRI)CAP 168 –Licensing of aerodromesUK (EU) No 139/2014 - The UK Aerodrome Regulation, UK Acceptable Means of Compliance and Guidance Material, and UK Certification Specification and Guidance Material for Aerodrome DesignCAP 790 –Requirement for an Airside Driving Permit (ADP) scheme

An aircraft has landed at a busy UK airport and taxied away from the runway. A tower controller asks the flight crew to hold position and the pilot reads the instruction back to confirm. The runway is clear and the controller is about to issue a landing clearance when they see that the aircraft is no longer holding its position.  It is now infringing the runway and continuing to roll forward.This is the first episode of a two-part series looking at runway safety and specifically incursions at commercial airports. We speak with aviation experts including the UK CAA’s Principal Aerodrome Inspector, a commercial airline pilot and an air traffic controller about the risks relating to runway incursions and how to mitigate them.Guidance and resources mentioned in this episode:CAP 168 –Licensing of aerodromesUK (EU) No 139/2014 - The UK Aerodrome Regulation, UK Acceptable Means of Compliance and Guidance Material, and UK Certification Specification and Guidance Material for Aerodrome DesignCAP 790 –Requirement for an Airside Driving Permit (ADP) schemeEuropean Action Plan for the Prevention of Runway Incursions (EAPPRI)

The pilot of a light aircraft is accelerating down a runway in southern England when the plane starts moving to the left. Trying to avoid a runway excursion, he rotates the aircraft early and before reaching a safe flying speed. We speak with AAIB Senior Inspector Emma Truswell about this incident and the findings from their investigation. Also joining us is Paul Tedder from the CAA’s General Aviation Unit who covers the safety guidance around take off decision making and pre-departure briefings.Reports and resources mentioned in this episode:AAIB investigation to Europa XS, G-REJPClued Up: Rejected takeoffs (CAP 2510)CAA Standards Document 14 (A): Class, type and instrument rating skill tests and proficiency checksCAA Standards Document 19 (A): LAPL and PPL Skill test (Aeroplanes) policy and guidance for applicants and examiners The Skyway CodeTraining Comm 2019

Reporting occurrences has never been more important and in this special edition we speak to the CAA's Head of flight Operations Glen Bradley and Aerospace Modernisation Lead Adelle Roberts about how and why we should continue to report occurrences.You can find more information on the Importance of occurrence reporting on the CAA website.
