The meet director, Nicky Moss, announced that there was a new
rule. That rule was to do with the recording interval on pilots' flight
instruments. It was to be set at five seconds or less. Most pilots have their
instrument set up like this anyway, so it didn't require anyone to make any big
changes.

They'd made this rule because the evening before 'A Pilot' had arrived at the
scorer's desk with a tracklog that showed he had gone into airspace. As a result
he was to be penalised for it.

A discussion followed, during which he showed the scorer that he could change
his C-Pilot Pro recording interval to 50 seconds and, hey presto, the airspace
violation disappeared!

The scorer being slightly older than a schoolboy saw through that trick and said
'No way'. The pilot wasn't satisfied so returned later and downloaded the 'new'
tracklog to the second scorer while the first scorer was away from his desk. The
first scorer saw it in the results later and called him on it. 'Come on mate,
that's not sporting.'
