The versatile VOR/DME approach

Sometimes we fly into airfields that appear to be surrounded by hills or restricted areas for example, so unless we happen to be approaching from a specific fix or direction, we may be forced to make our approach while ‘threading the needles’ between mountain peaks or busy airspace – not a great idea. But help is at hand as by again combining the information provided by the VOR and the DME, we may be able to make a simpler and safer approach to these types of airports by flying the DME arc.
