May 13, 201214 yr In-regards to the MD-11, is VCL the Vzf (i.e., minimum clean speed)? Specifically, in regards to the following, what does VSR and VCL denote?

VFR is the speed that you retract the flaps at. VSR is the speed that you retract the slats.. Kenny Lee"Keep climbing"
May 13, 201214 yr Author Thanks, Bank Angle. I guess I better get clearance to go above 250 knots. Matt King
May 14, 201214 yr No need to. The 250 under 100 rule does not apply if your minimum clean speed is over 250. Just fly 270 and it will be OK. --Peter Fabian
May 14, 201214 yr No need to. The 250 under 100 rule does not apply if your minimum clean speed is over 250. Just fly 270 and it will be OK. ATC expects you to fly at 250 knots or below. If your climb speed is greater than 250, you need to tell ATC to get clearance to go faster than 250. Now, if they say no, tell them that according to federal regulations you are the pilot in command and operating your aircraft safely and legally within reason, of course... Kenny Lee"Keep climbing"
May 14, 201214 yr This has been discussed ad nauseum Kenny. The rule states clearly you may fly at 250 or lower, or if min clean is more than 250, then fly at min clean. ATC will figure whats up anyway if they see an MD-11 or B747 or whatever flying faster after departure... --Peter Fabian
