    Subject: Commander decent
    --> Commander-List message posted by: "Moe" <moe@rosspistons.com> Gents, Thanks for all of the comments on flap extension. Does anyone have comments on slipping the plane, on final approach, with gear extended and full flaps below 150 mph? When making a straight in approach to HHR, in VFR conditions, we must remain at 1,400 (above threshold height) until 2.8 knots from the threshold. In the past, I have been using rather severe "S" turns, or slipping, or asking the tower for a left 360 turn in order to get down at a manageable speed. The "S" turns seem to scare people on the Lowe's parking lot, and the left 360 disrupts the orderly flow of traffic in the pattern. Further comment will be greatly appreciated. Happy New Year Everyone! Moe Mills N680RR 680F(p)

The "S" turns seem to scare people on the Lowe's parking lot, and the left 360 disrupts the orderly flow of traffic in the pattern Good Morning Moe, First question, if I may, where is HHR? As I see your problem, you need to descend at around 500 feet per nautical mile or 434 ft per statute mile. While it has been a very long time since I last flew any Twin Commander, I would think that a power off descent rate with full flap and gear down would result in well over 500 feet per nautical mile. Most competitive twins will descend around 600 to 650 feet per nautical mile traveled in landing configuration. Any head wind at all would help. While I would imagine a simple slip would work very well, wouldn't a low power slow speed descent also work? What is your desired minimum approach speed? Do you use knots or statute?

    Subject: Re: FLAPS
    --> Commander-List message posted by: "Moe" <moe@rosspistons.com> Bill, The initial problem is convincing the unwashed masses that the airplane is pressurized. Trying to keep these unwashed types out of the inside of the plane, I tried showing them the blower and equipment in the rear fuselage, only to be told that it was merely a fan to blow through the air conditioner. After allowing them to come inside and view the pressurization control, some seem to still be a unconvinced. The FAA registry in some instances does not mention the (p) in the model information as it was optional equipment, and in some instances it does. ???? Personally, I wish that the designation was 680FP instead of 680F(p), due to the fact that when typing I can't use the top key board keys without looking at my hands. This problem is further exacerbated because one must hold down the shift key with the left pinky while hitting the '(' AND the ')' keys. Wing Commander Gordon in right....life is not simple anywhere.

    Subject: Re: Commander decent
    --> Commander-List message posted by: "Tom Fisher" <tfisher@commandergroup.bc.ca> When I am doing nap of the Earth flying and have to descend rapidly (non-geared engine) into the next valley I drop my gear and flaps to obtain a descent rate of 3,000 ft/min @ 120MPH. The aircraft appears to be quite unstable in the yaw axis, given that, I would not side slip with full flaps. When I approach the airport I intend to land at I TELL the controllers what speed and maximum descent rate I am able to maintain and that I will need a back track once landed to clear the runway. That way they have time to space other traffic ahead and behind me to accommodate me. Too many times I have had an aircraft launched right in front of me supposedly on an immediate take-off requiring me to over shoot. My local field is now trained to give me room, they advise other traffic about the "fast moving Commander" (110 MPH) on approach. Your geared machine deserves respect from the controllers and perhaps they can handle you more appropriately if they had a heads up of your requirements. Tom F.

He has the classic problem that pilots based in complex airspace (or steep valleys) face. Tom Fisher said no to slips. I've slipped the short body Commanders with half flaps and gear down and do not remember any bad handling characteristics. Sounds like a good excuse to go fly. Set a "hard deck" altitude, set up in approach configuration (or just half flaps) and try it out. Be sure to report back. I'm looking at the LOC RWY 25 approach and see that you can cross DEMON at 660', 2.7 nm from the threshold. I take it your 1400' restriction is some other limitation? Do the local controllers make you adhere to that if you're on the IFR approach in VFR conditions? If not, I'd execute the LOC approach all the time. I can see that LAX controllers may not like the parallels with their airport; the GPS RWY 25 looks like a more ATC happy solution, plus your GPS may give you pseudo glideslope. Any of that a possibility? Wing Commander Gordon PS: Bill Leff! Great to see you active on the email net! Life is not simple anywhere. Probably less so elsewhere.

I have two inviolate rules: no more that 2" MAP change at a time, and the engines produce power any time I'm not using the brakes. These rules force me to be at least 60 nm ahead of the airplane or I'd be doing a lot of go-arounds. Therefore, I usually surprise Towers who aren't familiar with the N-number by approaching the field at an airspeed they associate with a single-engine commander, anticipating the slam-dunk on to the runway. On speed at the perch (100-120 KIAS) and with approach power setting, I've found the 680FL(P) sticks the touchdown markers from 1,500' and 3 nm every time with full flaps. I use HHR to practice landings with students in the Cirrus SR-22. The turn to final from the freeway requires them to be on-speed (119 KIAS in that airplane) and still may require a slip. But, more than anything, the parking garage and the raised surface of the 105 messes with their heads. So, even if they make a perfect approach from the freeway, or even slightly high of a 3 degree glide slope, they feel like they are too low and pull way above the glide slope. They play catch-up the rest of the way to the runway, and more often than not, end up going around and trying it from a standard pattern. I've never had the commander in to HHR, but if I did I'd approach it the same way as in the Cirrus. Straight-in: stay slow over the freeway, drop the flaps, and lower the nose to Vfe to burn the altitude. Parallel to the freeway: drop the flaps and burn as much energy as I comfortably (for the passengers) can in the turn to final. Individual results may vary!

    --> Commander-List message posted by: YOURTCFG@aol.com HI MOE. I keep my commander on a 2400 strip with real 50 foot obstructions on both ends. I routinely slip the airplane. It slips fairly well. I have only slipped it with full flaps. No adverse handling characteristics, it recovers naturally, all by itself. There is no tendency to drop the nose, nor does it pitch up (like some floatplanes). I have slipped to an airspeed as low as 60KIAS, although I think the pitot tube gets blocked a bit in the slip so the speed may have been a little higher. The only caution is that once slowed, the Commander takes a bit of encouragement to re accelerate so plan for that. Have fun jb

N680RR has dual air speed indicators, with a pitot tube on each side. Will try to check them against each other on next slipping approach to see if there is any difference in the upstream and downstream sides.

    Subject: Re: Commander decent
    --> Commander-List message posted by: "Moe" <moe@rosspistons.com> Wing Commander Gordon: Thank you very much for the reply. As always, your good advice and wise council is muchly appreciated. As mentioned in my reply to JB I have been slipping the plane at about 100 mph with gear down and full flaps. Although aggressive rudder action is required, the aircraft handles well, and the sink rate increases quite rapidly by slipping. Running north and south almost directly over DEMON along the 110 Freeway is a Los Angeles helicopter routing, thus, when flying into HHR VFR there is the altitude restriction of 1,500 (approx 1,440 above the runway). When the LOC RWY 25 approach is used, the choppers are held until the aircraft shooting the approach is clear. On clear days it is much easier to go into HHR VFR than to go in IFR. To get a "pop up" approach you need to go down to SLI (Seal Beach VOR). Also, in many instances the LA APPROACH controllers frequency is so busy that it can take several minutes just to get him to answer you back. Other than when coming from the south east (San Diego) on an IFR flight, going into HHR by shooting an IFR approach is most definitely NOT a time saver. The guys in the HHR tower and LA APPROACH are really a great group, who have been very nice to me over the years, so I try to accommodate them as much as is practical.

    Subject: Re: Commander decent
    --> Commander-List message posted by: "Moe" <moe@rosspistons.com> Nico, The situation with geared engines is that the engines can never be used to slow the airplane down. The prop should always be driven by the crankshaft. Also, on the ground the engines should never be run below about 1,200 RPM (1,500 is better) with the Simmonds fuel pumps. At lower RPM the engines will surge which loads and unloads the sun gear against the planetary gears. I won't go into the part about the 5/16" bolts that hold the gear drive to the drive plate.

    --> Commander-List message posted by: "Jim Addington" <jtaddington@charter.net> My two cents on slips. Be sure to keep the nose below the horizon when doing slips, if you get the nose up with the airspeed indicators being unreliable as they are and it does stall the shiny side will not be up for long. The Commander having a high wing should not give the problems that could come up with the low wing aircraft, such as the fuselage blocking the upper wing. Yes, I have slipped low wing planes too, probable as much as any one, but, there can be trouble. Jim A N444BD

    --> Commander-List message posted by: Nancy & Roland Gilliam <amg@nc.rr.com> Thanks Bill for emailing me direct on the 500 and 500 A differences. Could the 500 airframe also be pressurized structurally? Just a question, in case someone asked.

    Subject: Re: Slips
    --> Commander-List message posted by: "css nico" <nico@cybersuperstore.com> I cannot remember ever having had a need to slip my straight 500 (which I flew for about 1,000 hours - measly compared to what some of you guys have spent in the front office), but then again, one could hang full flaps and gear out, nose her over and fall out of the sky like a brick. The few hours I spent flying a 680 - now let me get this right - (P), I had ample time to keep positive thrust in regular descents, so no need there. It never dawned on me that a slip should or should not be attempted, which is why I value this group because there is always something new to learn somewhere. From a gut-feel stance, I would have been hesitant to attempt a slip for fear of the large wing putting the tail in turbulence or exposing the large tail to undue side-ways forces. Sudden high rudder inputs apparently caused structural failure in a large jet reported not too long ago. Do I recall that correctly? Apparently I would have been unduly cautious. What a machine!
