Please do tell me how to fly direct to RNAV point "NOVOR" raw data?
When you were flying little aeroplanes, how did you find a town, or turning point without a navaid at the point you are looking for?
It's called
navigation - you have a working clock, a working heading reference, you can plot a fix to determine your current position ...
In your particular case - the dual IRS's in the 737 were still working, all you had to do was look up
for your actual track & ground speed, and get a chart out to see where the place was.
"Children of the Magenta line" indeed - that pilots today even have to ask
how to do it, as though it is an impossibility without vectors, shows quite a bit.
In Australia, after the Omega navigation system was decommissioned, my airline had us flying with no area navigation system at all in a BAe 146 - just NDBs and VORs. On many of our routes we were completely outside navaid coverage (of any sort) for up to an hour. In one instance I was flying an aircraft with an unserviceable autopilot from Cairns to Darwin and had to divert north around a cyclone in the Gulf of Carpentaria.
The solution (diverting left and right around thunder heads, outside navaid coverage of any sort, without autopilot) was simply to get a chart out, and run a series of
air plots for each change of heading for an hour, then apply forecast wind vectors to ded-recon to a point back on the airway, and pick up the VOR radial.
