I have witnessed many rampys doing walk arounds. Firstly I have no idea why on earth they assume they should be doing one.
Secondly, any rampy arrogant enough to undermine the procedures and processes already in use have no place working airside.
I have also witnessed rampys slamming a belt loader into the side of an aircraft's fuselage. They went and got the chief rampy who inspected the aircraft and gave a thumbs up to his workmates. At no time did they inform the crew or the engineers. It wasn't untill my colleague informed the engineers that the aircraft was inspected by a qualified engineer.
Arrogant rampys need to know their place and this is another example why engineers should be present on tarmac.
