Action description

Babcock MCS has issued a safety alert to flight crew of TCAS II equipped aircraft, which alerts pilots to the ground inhibit functions of the TCAS II system and the control response requirements for resolution advisory manoeuvres. The safety alert also highlights the mandatory compliance requirements of resolution advisories. 

Babcock MCS has also updated the pilot training courseware and syllabus. This includes the development of a recurrent theoretical and practical training module to address potential knowledge gaps.

Further, the AW139 pilot recurrent simulator program for 2022 has been updated to incorporate:

  • Flight crew theory training on TCAS II systems knowledge, in particular ground inhibit functions and resolution advisory control response requirements.
  • Simulator training sequences including elements relevant to the occurrence.
  • Development of a simulator instructor guide for TCAS scenarios.
