Default How wide is an NDB approach course?

What's wrong with that approach, at least until leaving MDA?


The 1200 ft tower that you can hit. It's located outside the trapezium
that defines the protected areas (inner and outer) but your VOR
receiver can be within 4 degrees of perfect (the more restrictive
standard for the VOR check - some COR checks allow 6 degrees) and your
needle need not exceed 3/4 scale deflection (the more restrictive
standard on the instrument airplane PTS - you are allowed full scale on
the partial panel approach) to put you right into the tower.
