'Positve Radar Control'
Hi,
In our ops manual, this is one of the requirements to descend below MSA. However I cannot find a definition or reference to it anywhere.
It seems quite a grey area in my company (Europe) when ATC send you to a waypoint and give you descent. Many will not go to the given cleared altitude unless above MSA or on a heading. Is this prudent and cautious or unnecessary? I dont know!! The way I understand positive radar control is that ATC are controlling your track and issuing descent based on their MVA's and knowing where you are going as they have cleared you to that point or you are on a star or other predicted route. Does it make a difference whether on a heading or not?
Whats the difference between positive radar control and radar vectors??
thanks in advance.
