Flying a SID without VOR guidance (BPK)
Today whilst doing departures I had a KLM FK50 request radar vectors due to an inability to fly the BPK SID. BPK VOR was notamed out of service, and the crew said something about not being allowed to use the FMS. It was a busy frequency at the time with landing traffic as well, so I didn't have time to quiz the KLM further.
Can anyone shed some light on this, any reason why a crew would not be allowed to use the FMS?
Any thoughts appreciated.
Gonzo.
