If not using an ILS with associated marker beacons, what instrument landing approach would have been used in those days to ensure tracking accuracy for the equivalent of a Cat 2 ILS?
Would that have been a GCA in 1943? if so, would the GCA in those days have marker beacons (aural only or cockpit lights) for height checks. Or would that be a BABS beam approach in 1943?
There wasn't much alternative in those days apart from a letdown using one of Mr Irvin's products.
