TERRAIN AWARENESS WARNING SYSTEM (TAWS) FLIGHT CREW TRAINING

[…]

SPECIFIC ELEMENTS FOR CONTROLLED FLIGHT INTO TERRAIN (CFIT) FLIGHT CREW TRAINING PROGRAMMES

(d) The following items are typical performance-based training objectives for the training of flight crew in the avoidance of CFIT: — anticipate terrain threats; — prepare for terrain threats; — recognise unsafe terrain clearance; — take appropriate action; — apply appropriate procedure correctly; — maintain aircraft control; — restore safe flight path; — manage consequences. (e) The following scenarios may be addressed as part of the training: — ATC clearance giving insufficient terrain clearance; — provision of a wrong QNH; — demonstration of terrain avoidance warning systems (if TAWS is installed); — engine failure making performance marginal, leading to a TAWS warning (if TAWS is installed); — ‘virtual mountain’ meaning the surprise element of an unexpected warning (if TAWS is installed). (f) More details can be found in ICAO Doc 9995, Manual of Evidence-based Training.
