The TGH™ system provides the client with the highest level of safety, reliability, and user friendly options that is available for aircraft ditching training today.  The monitoring and expandable control functions offer the client accurate, and repeatable training routines. Options for the system includes documentable training routines, as well as the ability to control and sequence other training devices such as wind, waves, rescue hoist systems, and other environmental variables for a complete and state-of-the-art training system.

  • The METS® Model 9000 TGH™ is mounted above the pool and features dual lifting mechanisms, integrated METS® remote air brake system, user settable variable ditching speeds, as well as a pneumatically operated redundant retraction system (RRS) to address the risk of power failure during critical (submerged) periods of the helicopter underwater escape training (HUET) training cycle.
  • The system is a cost effective, very low headroom, retrofit design for replacing aging hoist systems, is very easy to use, and can be installed indoors, outdoors, in pre-existing, or in new facilities as required.
