Helipad Obstacle Guide / Plate (CAT A)
Can anyone give me info on what various operators use to estimate distances and heights of obstacles in the vicinity of frequently used landing pads? I saw an example of one a few years ago. It was an overhead shot of a hospital pad (non-elevated) with range rings superimposed on it and details below of the obstacles within the various ranges detailed (eg, 100-200M Large tree at 320degM, 90ft AHE). The copy I saw was of poor quality and Im looking for good examples on how to format the info in a clear, pictorial form.
Can anyone provide me with examples of such plates? I am compiling a database of our frequently used sites with a view to providing crew with info about obstacles so that they can select the correct CAT A or CAT B profile for departure and approach.
Any guidance much appreciated.
