one of the big concerns was the flight attendant getting a shock from the A/C electrical supply which is only 115v at 400hz the big problem is the Hz which is very close to the heart rated speed and can have very serious concerns i hope the flight attendant attended a hospital to check the heart operation as per procedures as heart attack can follow, due to the Hz and heart rate being at similar rate.
The other concern? i will leave that up to you.
I have worked in this area in MAS and money is a big driver..say no more except when i work there under my Aust lic i work to Aust standards, they do hate it but i am a temp contractor and can demand a standard that is similar to Aus, I wish that there was the standard in places like this but they only do what is required and do push to reduce the standard to meet costs.
Aust standards are good if not the best why send A/C O/S? cost at what cost?
