Well, in my last company we had a 700 foot cloud base limit for base training. It is not ideal but it is a very good exercise for the students. If you can't hack a visual circuit in a 700 foot cloud base then perhaps you should not be signed off?
With the advent of JARs and the requirement for 6 landings, it really proved to be very time consuming to do 6 full procedure departures and arrivals and let downs if the cloud base got below 700 feet.
What's wrong with you people nowadays?
Can't you really cope with a visual circuit at 700 feet?
Pathetic.
