[QUOTE=loubylou;3016512 . The only condition there is that the controller can see both aircraft, and the it is reasonable that the aircraft given the conditional clearance to would see the aircraft that the conditional clearance relates to. ( ie you at the holding point can see the dep/landing aircraft)
I think I've explained that properly - but then it all makes sense to me!!!!

"and the it is reasonable that" , Unfortunately the relevent paragraph doesn't say that it simply states that the A/C that the conditional clearance relates to should be visible to the Pilot /driver /Controller. Whilst I generally agree with your sentiments , this is already causing interesting discusions as to whether the said A/C needs to be continuously visible ( I do not think that is the case) more importantly though is the fact that Mats pt one ,now states that the subject should be visible ,Granted it does specify a limit to the number of A/C ,as it always has done, BUT how do we the controller know that the observer has the correct A/C in sight?
Common sense should prevail but in these days of SMS etc if it's not written in black and white somebody somewhere is going to interpret the paragraph in a way which would erode any advantage gained by a conditional clearance by increasing the R/T loading prior to issuing the damn thing
It would appear to me that by increasing the R/T inorder to prevent RWY incursions any actual instructions to Cross/Not cross are getting lost in transmission from one brain to another ( thats VIA the mouth and ears ofcourse)
