So you hold the rpm at 2,700 - by continuing to modify pitch as altitude rises in order to hold the 2500 ft/min climb all the way to 18k?

Thanks for ino.

At around 10/12K I ease the throttle but the PP doesn't need hardly any adjustment to maintain (or around) 2700RPM - I then continue to around 18/20K - adjusting my Climb rate for a good climb speed and more air flowing through the rads, my climb rate is changing anywhere between 1200 - 2200 fpm as airspeed drops and eng temps rise.

As others mention, Gravesend is perfect for climbing - I will be at 18K when reaching the English Point. I have never timed it though.....


Edit. I checked both the 1a and 2a while on ATAG - About 12 minutes to 18K (but the way I climb rather than the book and Rad fully open). In both cases I tended to watch my airspeed more than holding a specific rate of climb - climbing up in steps when necessary so to speak. The Spit1a was more forgiving regards full throttle and CEM and ties in with a section of Blackdogs post (which I just noticed).
