Yes ATP ...your point being ??
I state again that filing RNAV on your icao flight plan is not an indication that you can conduct an RNAV approach . ATC may assume this but the approach ,enroute and arrival phases are all generically filed under RNAV .To conduct the APPR requires regulatory approval . So quite simply , if they wanted it , they could have requested it , but guess what , they didn't review their options . Maybe ATC should have conducted their approach briefing also .
So yes , ATC could have offered , ATC could and should have..ad infinitum.
Perhaps everyone should read the report : the probable cause is attributed solely to pilot error .
The rest are findings ..In case you don't grasp the difference( I assure you , there is ).
The approach Controllers wx data of tailwind and moderate showers doesn't ring alarm bells and the fact that the crew requested straight in ..(traffic permitting , most if not ATC will comply with the Pilot's request ) ..seems a lot of cues were there .
Not the first time either , was it?
