Hi Rock;
Good to hear from you. You'd be surprised how often we agree :-)) I think a lot has changed since the old days when I was doing primary instructing. I watched it change through the years I was doing nothing but aerobatic instruction, then through my "consultation" years :-). Getting a full time student from start to finish seems to be the exception today rather than the norm. The old FBO's where you drove out to the local airport on Sunday; found a CFI who had been at that airport for a hundred years and signed up to take a lesson each weekend are hanging in there, but becoming more and more rare as time goes on. It's been interesting for me, watching this transition as I wandered through the path of my career in aviation. It's a much more complicated world out there now as you know all too well, and the whole scenario involving learning to fly has changed a great deal. People move a round a lot more; jobs change like the weather; the costs have skyrocketed; lawyers and insurance have entered the equation now,and CFI's have a tendency to be part time and transient. It's a whole new world out there. Frankly, I really miss the old days. There are still a few of the old airports around where you can go and sit around the picnic table on a warm clear Sunday afternoon with the same bunch that show up like clockwork every week, and talk flying while everybody "grades" the landing just made out on the runway a few yards away. At our little grass field where I learned to fly, we actually had large white cardboard signs with a 0 on one side and a 10 on the other side like the figure skater cards. After some poor character would land, we'd all be sitting there holding up the cards showing our "choice" for the score as the pilot taxied in. There's a serious training point that I could make here about all this fun. That scenario I just described was also a learning environment. New pilots learned quite a lot about flying during those fun filled Sunday sessions around the old picnic table. I can remember many times sitting there with a student watching a landing and getting a question that changed the atmosphere immediately into a serious training mode. The whole table would listen as the more experienced straightened out things for the new pilots on something. You could see the learning in their faces. Yup...that ole table out there was the best classroom I ever had to teach in! :-) The 141 operations were different of course. We pushed them through faster. We still did a good job, but for me, it was never the same as that old airport on a Sunday morning with everybody gathered around having fun and learning something every second they were there. Sounds like you did a hell of a job with that "captive" student, and in minimum time as well. Have a great and safe new year Rock; I'm sure we'll be "talkin" again :-) Dudley wrote in message ups.com... Dudley We agree again g. I recently finished a student who is a rarity in that I have been his only instructor. He committed to hit it hard and steady and he passed his PP check ride with a total of 41.3 hours when he walked in to take it. He flew 3 times a week, got a 98 on his written and the DE said he was a delight to fly with and no weak areas except in maintenance paperwork. Was fuzzy on AD vs service bulletin vs regular entries in the logbooks. He took roughly 3 months with a few weather interruptions like Hurricane Ivan, and spent just under $5000 all inclusive with headset and other pilot tools. He is the first student I have had "captive" in many years. As a Chief Instructor at a number of schools, nearly all the students had been exposed to a variety of instructors and I did phase checks as well as standardization rides for my CFI's. I have often recommended a student fly with another CFI to see if there was an area or presentation that was better for that student. Sometimes it was just personality that made a difference. My own style is pretty relaxed, low key, and demanding as hell. I have high standards of performance for those I choose to fly with or give instruction to and am relentless in demanding they meet those standards. But, as you know, I am one of those pilots who has been everywhere and done nearly everything of interest to guys like us. Best personal regards and best wishes for a successful and healthy New Year to all. Ol Shy & Bashful |

![]() While 100 rpm is not a big deal, developing a routine in the early stage of training is very important. An experienced pilot can handle a large number of variables. He can fly the approach at any RPM, airspeed and flap setting. But a new student needs a more limited set of variables. So we need to fix a few parameters such as RPM, airspeed and flaps etc and only leave a few others as variables such as altitudes to float. With practice they will be able to develop the experience to handle all variables at once. From personal experience, all my students soloed in less than 20 hours. The ones who exceeded 30 hours flew with multiple instructors.

Precise power setting ain't all that important, yet some students will devote ten long seconds to massaging the tach to get an exact number because that's what their instructor told them (if you think ten seconds is a short time, I will gladly stick my finger in your eye and hold it there for....heck, two seconds be enough to make my point?).

I think that continuity is very important...and having multiple CFIs gets in the way of that. By the time you are working on your CFI or your commercial, you pretty much already know how to fly...you are perfecting and advancing your technique...but you already know how to do all the basics.

From the instructor point of view, I wholheartedly agree with you. With the
way the flight instruction system works, most CFI's only work for a couple of years before moving on. Further, most have little or no instuctional experience before becomming CFI's. When you consider the learning curves associated with flying (remember that most CFI's are reasonably low time pilots) and teaching (perhaps more complicated than flying), the chances of you getting flawless instruction is rather small. Flying with multiple instructors has advantages for both you and your instructors. First, different instructors have different stregths and weaknesses, so where one is weak, the other may be strong. (I used to teach with another instructor who was the diametric opposite of me. It was a great learning experience for both of us as we would get frequent feedback on how we were teaching.. we used to go out for a beer every week, and call it our "staff meeting". It's too bad he moved on.) Even if there are no quality issues, you'll still learn a lot. Remember that there is no single "right" way to fly. Your job, as a student, is to learn a way that is both "not wrong" and that works for you. (Unless you're planning to go professional, at which point you'll need to learn to fly the "company" way.) By flying with several instructors, you'll get ideas which you can use when developing "your way". (Hopefully your instructors will teach at higher than the rote level, and will give you the latitude to find a way that blends safety and your own personal style.) Of course, all of this is based on the premise that the instructors actually talk to each other. Sorry for rambling. -Rob "gatt" wrote in message ...

Bob,
You're absoloutly correct, except that I disagree with your specific example. :-) Setting your power precisely one downwind (or, at the level-off just prior to the FAF if you're flying an instrument approach) allows you to trim the airplane properly for approach, and is the one time I want to see precision from my students. This makes the correct airspeed much easier to control, and gives you much more time "heads up" during the rest of the approach to land. You'd be amazed at what a difference a hundred RPM can make. Here's an experiment that seems to work on most light singles (and some light twins). From a reasonable altitude, put in "approach flaps", and trim the airplane for "approach speed". Then, retract the flaps, and notice the indicated airspeed. (Usually this is right around the top of the white arc, but not always. If it's above the top of the white arc, disregard everything I've said... you'll need to fly the plane :-).) Now, at pattern altitude, trim the airplane to fly this airspeed while level, and note the required power setting. Now, bring the power back a bit to start your descent to land, and put in your approach flaps. Shazam, you'll slow to approach speed within a couple of knots without much effort, giving you more "look out the window" time in that part of the pattern where a lot of accidents happen. In a Warrior-II, 152 or 172P with just an instructor and a student, setting 2100 RPM on downwind, and trimming for hands off flight seems to set the airplane up for a normal approach speed when using 20-deg of flaps, and the short-field approach speed with 30-deg of flaps. If you have more people, add 100 RPM per person. If it's gusty, add about 100 or 200 RPM for the appropriate speed boost. In an Arrow-II, about 21-inches of manifold pressure (regardless of RPM) does the same thing. (What is it with "21"?). Just my opinion. :-) -Rob "Bob Gardner" wrote in message ...

I have to try your method. Maybe I can get my pattern flying without
'thinking' at all. Right now it is semi-smooth but completely not mindless. In a Warrior-II, 152 or 172P with just an instructor and a student, setting 2100 RPM on downwind, and trimming for hands off flight seems to set the airplane up for a normal approach speed when using 20-deg of flaps, and the short-field approach speed with 30-deg of flaps. Are you sure about the RPM? The method I've been taught is drop the RPM to 1600-1700 (weight depending) when abeam the numbers and throw in one notch flaps and pitch for 90 KIAS. On base, 2 notches of flaps and pitch for 80 KIAS and on final 3 notches and pitch for 70 KIAS. At 2100 RPM, I'd still a few hundred feet off the ground. Gerald |

2100 is for when you're level (i.e. before you're abeam the numbers) and
trimming the airplane. Once you're abeam the numbers, you bring the power back to something that gives you the rate of descent you'd like (and where the previous posters point holds true... do get too fussy, look out thte window at the airplane entering the pattern on an extended base or a long final), put in your flaps, and slow to approach speed. Also keep in mind that the actual power setting may vary from airplane to airplane. Good luck, -Rob "G. Sylvester" wrote in message news ![]() I have to try your method.

Also keep in mind that the actual power setting may vary from airplane to airplane. The way I look at the pattern, what's really important is airspeeds, not power settings. Power settings are just a way to get the airspeed you want. The most critical airspeed in the pattern is your final approach speed. Everything else is just executing a controlled transition from cruise speed to final approach speed. For most light planes, if you fly base 10 kts faster than final, and downwind 10 kts faster than base, you should be doing OK. This should give you a good target speed for downwind. The problem is, you can't set airspeed directly, you can only set power. So, it's a good idea to have a target power setting for downwind. For most typical trainers, somewhere in the 1900-2100 RPM range is about right, but ask your instructor for a good number to use for whatever you're flying. You set that when entering the pattern (along with whatever other configuration changes you're going to make, like gear and flaps), and give the plane a little time to settle into a stable airspeed. Then you can adjust the power if needed if you didn't get the airspeed you wanted. Keep in mind that you need to fit in with the existing traffic flow. You may normally fly downwind at 90 kts, but if you're following somebody going slower, you need to do something to avoid crawling up his exhaust pipe. This can get really interesting as the mix of types gets extreme (Bonanza following a Cub, for example). |

Means and ends are in the eye of the beholder. The way I look at the pattern, what's really important are airspeed and altitude. Power settings allow me to adjust either, but once I've begun my descent (usually from abeam the numbers, but not always depending on traffic concerns) power settings are just a way to get the *altitude* I want, and the descent angle I want. I use my pitch controls (elevator and elevator trim) to adjust airspeed at that point. Of course, they all interact. It's like asking "Bernoulli or Newton". But don't discount someone else's mental paradigm just because it's different from yours. ![]() The point that started this whole subthread was simply that students (and even full-fledged pilots for that matter) can fixate on setting a particular RPM, when that's not really all that important. A particular RPM setting is only going to work on a "standard pattern day" (i.e. no wind, no traffic, exactly 800' or 1000' or whatever feet AGL you pick as standard, turns at precisely 45 degrees and final, etc.). Any variation from this standard is going to require adjustments to throttle to maintain the desired performance for the conditions. So why waste time and concentration getting the throttle at exactly some particular setting, when getting it in the ballpark using muscle memory (i.e. general knowledge of the "correct" position) and audible feedback (sound of the engine)? I believe that Bob was saying just that, and I think his comment was right on the mark. It's funny the turns this thread has taken, but I disagree with Rob's attachment to precision in this case (even though I do generally believe that precise control of the aircraft is very important), and I don't understand what debating the *actual* specific RPM settings does to address the original point. The problem is, you can't set airspeed directly, you can only set power. I beg to differ. I set the airspeed all the time. I can manipulate the elevator directly to obtain the desired airspeed, and I can then set the trim to allow the airspeed to remain at that desired. So, it's a good idea to have a target power setting for downwind. For most typical trainers, somewhere in the 1900-2100 RPM range is about right, but ask your instructor for a good number to use for whatever you're flying. You set that when entering the pattern (along with whatever other configuration changes you're going to make, like gear and flaps), and give the plane a little time to settle into a stable airspeed. Then you can adjust the power if needed if you didn't get the airspeed you wanted. If you simply adjust power, you won't get the airspeed you want, ever (well, not counting a sudden decelleration at the end of a descent induced by a power reduction). You have to change your pitch in order to get a new airspeed that will produce the performance you want at the new power setting. More relevant to where this subthread started, yes it's good to have a target power setting for downwind, and for the descent as well. But there's no need to spend 30 seconds (or whatever) fiddling with the throttle to get the power setting "just so". You smoothly, calmly, and quickly set the throttle to the general vicinity of the correct spot, and then make adjustments as necessary during the approach. Adjustments you would have to even if you managed to hit the exact throttle setting you had targeted. Pete |
