I fly in and out of LHR regularly and have been trying to figure out where we are when we hit our cruise height.
Question 1: I gather we must sit at some intermediate altitude for some distance out and then climb to the cruise altitude. I did a search, Google and here, trying to chase tracks and data but I have only found climb rates from take off or comparisons of climb rates. The route to YYZ usually takes us towards Nottingham and then to parts unknown. Where could I find such information?
Question 2: When I flew Concorde to YYZ we sat at approx 25,500 to the Bristol Channel then went supersonic. I saw on the dials we rocketed up in speed and height once they announced the reheats coming on. What I could not figure out (champagne and excitement) where we were geographically when we hit 54,000 and Mach 2. I know from the way points (correct term?) we cut around the south of Ireland and up to lat 54 before turning west (EGLL CPT UG1 SL2 MALOT 54N20W ...) Anyone know where the general point would have been that we hit cruise height?
