Do I need to provide proof or would a reliable (PoA) witness suffice?Do It!

If ya do it right it'll be in the 'news' Thats proof enough.Do I need to provide proof or would a reliable (PoA) witness suffice?
I gather you're at DMAFB? Just curious, since I'm based at KTUS.
What are your initials. I'm TM. Ask Irving Rodriguez, Mike Frye and Diane Seven how cool I am.
"Make left/right 360" will work as well. Though, I don't recall ever having to issue it.
How about a 720*?
One quiet night, when I am the only one in the pattern at our class D, I want to try this.
The twr guys know me so it should be no problem.
I do get the point about having SA that you are trying to make and no one has ever had too much SA.
I differ from you a bit on the "depart the pattern and report downwind again at a speed compatible with the traffic pattern". "Speed compatible" and "reasonable speed" are way too subjective and mean very different things to higher performing planes and each plane driver. I'd use different tools in the box. i.e. Use both right and left traffic, inform the higher performing aircraft to fly his pattern 500' higher, extending downwind, making short approaches, issuing 360 on downwind, instructing an aircraft that is doing touch and go's that this one will be a full stop taxi back due to pattern saturation, doing a better job with 3000'/4500' runway separation, maintain max forward speed, reduce to slowest practical, etc. My last resort would be to politely ask an aircraft that you've already given clearance to enter the airspace to exit it. If you couldn't take one more plane you should have known that and told them on initial call to remain outside the D/C airspace until you had room.
Just respectful slight disagreeing with you. Thank you for past service keeping all us separated.
On instrument approaches I used to try to keep my speed up in my Cessna's and Piper's as long as possible under the belief that I was helping clear the airspace faster arguing that staying at 120kts made the average 10nm GPS approach only 5 minutes. To fix me of my habit, my instructor took me up as his safety pilot and flew the same approach himself 3 times to MAP with me timing each one.
The first time he flew as I had at 120 until dirtying up inside the FAF and it took as expected between 4.5 and 5 minutes to the MAP.
The next he flew he was already dirty at the IAF and flew at 90 the entire way and it took as expected be 6.5 and 7 minutes to the MAP
The last time he flew at 120 until just outside the FAF where he dirtied up and flew 90 the rest of the way. Took 5.5 to 6 minutes.
On the debrief he asked me which approach looked best and easiest. My instructor flew really solid approaches and I didn't get the impression he exaggerated any of it to prove his point but I had to admit the approach at 90 the entire way was the most accurate of the 3 approaches, had the least intense workload and while 2 minutes seemed a lifetime to me on paper neither the controllers or fast mover behind us seemed to care and it was over before I knew it.
It was the hybrid approach that got dirty just before the FAF instead of after which was still smooth and less intense that really drove home his point. His point being that 30, 60, 90 or even 120 kts difference in airspeed doesn't make a huge difference in time over the short distances involved in an approach but it does make a huge difference in the workload and controllability of the airplane especially as you are approaching to land and his example approaches gave a very visual reminder of a phrase my grandfather used to say: "slow down, you'll go faster."
These examples definitely apply in pattern work where that extra speed isn't a huge impact, especially if that speed is outside or at the boundary of the airspace with plenty of time to still slow down as was what sounded to be the case in the OPs original post. While I understand fully that these planes could be flying slower and it usually the bad planning and lack of skill on the part of the pilot that causes them to insist they cant get any slower, short of super STOL takeoff/landing competition where I've seen planes get off the ground in as little as 17mph, sequencing a slower 60kt plane with a 180kt plane is just a matter of positioning. I do understand the added complexity and difficulty in sequencing fast movers with slow movers particularly at a training airport where the slow movers might not be doing exactly as the controller wanted but I also know the FAA didn't just come up with their speed restrictions out of thin air.
Some controllers are better at it than others. I was flying a 170, 172, and the Navion in and out of IAD for years. You could tell which guys had a clue and which ones were idiots who tried to line up the slow movers at the gate.As a controller, I would like to see pilots realize what it takes for a controller to manage a mix of slow, fast and heavy aircraft with no reduced runway separation on ONE 13,000' runway. I do it every day.
