framer agreed.
If and I mean if it had a colour map GPS..... a GNS430/530W (even a G495) the minima for the RNAV is quite good with DGPS and with a VERY accurate runway aligned and accurate QNH set I would bust the minima a little bit too. Very carefully so long as you were very accurately aligned. Problem is if the fog is thick as custard right to the ground......
Now if they only had a NDB and VOR to use, which are not runway aligned approaches, you are stuffed!
How the heck did they get into this situation to begin with?
