With parking systems with their various idiosyncrasies and marshalers seemingly all with different tempo of hands coming together in the X for final spotting it does not matter how many outside cameras would be fitted. The last
20 metres or so there is nothing more one can do but focus straight ahead. .
In the past I cant tell you how many times I held off the stand waiting for two wingwalkers and marshaler, with lighted wands required at night.
Now our mobs' FCOM requires none. No marshaler, no wingwalker, at certain airports with these magic systems that supposedly scan the ramp safety zone for obstacles and movement..
Already lead to problems.
