Part 91.117 Speed Restriction

[ExpWayVis31]

Perhaps stating the obvious but, keep in mind terrain and your 2nd, 3rd & 4th segment climb gradient. There are many places where you want to be 2500' agl or higher before you push the nose over, accelerate and start your clean up.

Then again there are some SIDS (ATL) that want you to "accelerate to 250 as soon as feasible". but that is a discussion for a another thread.

Haven't we covered this before, I guess other factors may be that if we help out a controller or he helps us out, who is going to report us? Like Sled mentioned (Life Guard flights), he could go fast below ten because the controller allowed him to, was he technically violating an FAR, the answer would be YES.

That is correct, we were in violation of the reg, but it was only done when we had a bonified medical emergency in progress and we had to get a letter of explination from the attending physician and put it with our letter of deviation that we sent to the FSDO. We always had the proper backup and the FSDO never pursued any of the incidents.

I've got to disagree on this one. The POI of my company has been clear, and we have had 2 crews violated from other FSDOs for exceeding the 200 knot restriction below a Class B airspace. The guidance for us is that configure whatever way you need, but you must maintain the speed limit. Just because out clean speed might be 220 doesn't authorize us to use that as our speed limit so that we don't have to stay dirty.

The letter you posted doesn't address this question at all. It refers to operations in C and D airspace within and below Class B.

If you are simply operating below a Class B area, and not in a Class C or D, then you can fly at clean maneuver speed, which is 210, 220, or 230 in the 737 I fly. This is expressly pointed out in our FAA approved company docs, but I agree that different POI's have a knack for confusing this issue. In the MD-80, clean maneuver can be as high as 265 on climbout.

Didn't the FAA try lifting some speed limits in some Class B's a couple of years back? I was working on the INS when they were doing that junk.

Yeah, they had a test program at houston a little while ago, I believe that the test is concluded.
