The sterile flight deck procedures were published in Regulation (EU) 2015/140 as an amending regulation to (EU) No 965/2012 on air operations.

during critical phases of flight (take-off, landing, etc.), during taxiing and below 10 000 feet (except for cruise flight). Sterile flight deck procedures are meant to increase the flight crew members' attention to their essential operational activities when their focused alert is needed, i.e. flight crew members should avoid non-essential conversations, should not make non-safety related announcements towards the passengers, etc. In addition, during these periods of time the flight crew members should focus on their essential operational activities without being disturbed by non-flight related matters, i.e. Not quite what the FAA meant when the sterile cockpit rule (CFR 121.542/135.100) was written back in 1981. by cabin crew, except for matters critical to the safe operation of the aircraft and/or the safety of the occupants. When asked what he thought sterile cockpit meant, one pilot told me, It’s where your maps are all folded and there aren’t any coffee stains on the arm rests or your clothing. The term 'Sterile Flight Deck' is used to describe any period of time when the flight crew members shall not be disturbed e.g. Reference: Regulation (EU) No 965/2012 on Air Operations, Annex I (Definitions) and Annex III (Part-ORO) Certification of products and organisations.Certification Support for Validation (CSV).Alternative Method of Compliance (AMOC) to an Airworthiness Directive (AD).Acceptable Means of Compliance (AMC) and Alternative Means of Compliance (AltMoC).Drones with class identification label C0-C6.Provisions applicable to both ‘open’ and ’specific’ category.
