It is, though it takes a bit of organsing. The other way round should be encouraged, espicially representitives from the company that come up with sops.
Surely they must know that flying slower aint going to do diddly squat in preventing you from levelling off, there is a myriad of reasons why you can't get a continous climb. We'd love to do it, but then I spose if we could do it all the time then we would be out of a job!
We were informed that one of these SOPS involves slowing to 210kts in the descent (in areas of low traffic density, to quote the pilot). Well that means when you were once number one you suddenly might become number three. Is that what the SOP designers are aiming for? Do the people that come up with these policies have operational experience or are they people that sit and look at stats?
(Thankfully all the pilots that were involved in this discussion intimated that they all thought the policy was utter rubbish and were perfectly happy to speed up!)
