Opportunity to gather European TAWS stakeholders around potential TAWS evolutions, also proposed at RTCA SC-231 level.

Evaluate making TAWS Premature Descent Alert more sensitive to early descents due to a mis-set barometric altimeter without negatively impacting nuisance alert rates, covering case as reported by BEA report on Airbus A320 9H-EMU incident at Paris Charles de Gaulle on 23 May 22

Consider means preventing the Forward Looking Terrain Awareness function be indefinitely inhibited by operators. Based on NTSB accident report of De Havilland N270PA on 25June2015 and NTSB accident report of Hageland Aviation Services, Inc., Cessna 208B N208SD on 2 October 2016. Alaskan operators operate routinely in mountainous area below class B TAWS protection altitude leading the crew to inhibit the TAWS to prevent alert.

Support initiative for advance TAWS lateral escape manoeuvre and evaluate potential harmonization with current TAWS standard
Consider the effects of GPS spoofing on TAWS equipment
Consider the addition of Low-Energy Alerting mode, if deemed appropriate, to the current TAWS standard. Related to NTSB accident report of Asiana Airlines flight 214 B777 HL7742 on 6 July 2013

Propose a joint activity with RTCA SC 231 TAWS for creating a recommendation paper (Internal Report) for actual TAWS MOPS evolution.
The intent is to re-open the DO-367 MOPS to include upgrades related to all or part of the 5 points above. A preliminary phase needs to be launched, to review each point, assess feasibility of envisioned MOPS upgrades and align within the group: this activity and internal report will enable to define the Terms of Reference of the future MOPS DO-367 upgrade.

In second step, take advantage of the TAWS evolution decided to synchronise TAWS MOPS activities with RTCA.
