What is the normal procedure regarding Stapleford, in that case? The top of the ATZ is 2185'. Would it be reasonable to route from the A13/M25 junction at Upminster direct to Cheshunt, where the M25 crosses the Lea Valley, thereby missing the Stapleford ATZ? or do you leave Thames and call Stapleford?
Unless you are transiting the CTR, you're probably better off talking to Farnborough North (132.800) than Thames radar. But regardless;
a) there is Class G airspace (and empty fields) between Stapleford and the City CTR.
b) you can go over - between 2185 and 2500 ft.
c) you can talk to them - but being A/G, they cannot tell you much.
d) whilst doing a or b, you put them on your second box and just listen in to get an improved situational awareness
However:
and even the City Zone has an upper ceiling of 3,000 ft.
Where do you see this? I see CTR(D) SFC-2500 and LTMA(A) 2500+. There is no way over City (outside class A)
?
