GM Guidance material

## GM1 ATSEP.OR.100 Scope

GENERAL

It is acknowledged that ‘power supply’ and ‘air conditioning’ systems and equipment can be critical elements of the aviation safety chain and that personnel should be competent in those areas. Personnel that maintain these systems should not be considered as ATSEP. In general, ATSEP do not work on these systems, but rather control and manage the release of power supply and air conditioning systems, to and from operational service.
