I read about the ACARS "In Range" request pilots can send to request cabin services, lavatory services, wheel chairs, assistance for unaccompanied minors, etc. What about other services such as catering and potable water; those were not shown in the "In Range" request page. Do pilots have to make those request via radio or are those request handled by dispatch?
Any insight into how all this works (who is requesting what service) would be appreciated.
Also, is the catering company providing the potable water as well or are those two separate providers?
