No need to worry about 'duty of care' - just do the job of an ATCO (Obviously this will vary from unit to unit depending on levels of traffic etc). Not sure why following the basic MATS 1 rules should agitate any LCE's?
When I started in the business in 1970, a wise old ATCO told me he reckoned that at the end of the day, if it had gone to rats & someone died, AIP's, MATS Part 1 etc. would count for nothing. It's something I've taken into account in my job to this day !
Would you be prepared to stand up in front of Jo Public, the Press & the lawyers at a Coroner's Inquest or Fatal Accident Enquiry, giving evidence that you didn't take action that might have prevented an accident, because the rules & regs didn't require it ?
The phrase "duty of care" wasn't quoted by the regulators in those days but I reckon it's always been there in one way or another.
