LHR inbound routes in 1969:
Some interesting points:
- the position of the 'OE' beacon is incorrectly shown as lying between the approach paths of 28L/R; in fact it was aligned with the 28L approach.
- ditto for the 'NE' beacon; it was aligned with the 23L approach
- navigation along Green 1 was difficult - the WOD beacon was displaced south of the centreline and there were no beacons defining the centreline (the Lyneham NDB was also offset) until the airway intercepted a specific Brecon VOR radial to the northeast of Bristol - pilots referred to this point as 'the bend'
- the base of the TMA was only 1500 ft in the WOD area - presumably to cater for the less than sparkling climb performance of some airliner types in those days
