    --> Yak-List message posted by: Ernest Martinez <erniel29@gmail.com> This may be a little off topic, but last year here in flat Florida, I encountered a rotor cloud right over our runway. I didnt know what it was when I first saw it but didnt give it much thought. It was moving from east to west at about 30-40 knots. Conditions were calm just before takeoff, just as I took off and got up about 50 ft a tremendous amount of shear nearly caused me to lose it, I thought I had control problems. I flew west out of the pattern, then decided to RTB to make sure there wasnt anything wrong. By that time that strange looking cloud was now over the down wind leg, again things got real squirley, so I headed NW until I was clear of that thing, then made an uneventful landing after that cloud was welll west of the field. Goes to show ya that you dont need mountains for this type of phenomenon.

    Subject: S/N Ratio
    --> Yak-List message posted by: Ernest Martinez <erniel29@gmail.com> Do not archive I'm gonna catch a lot of flak for this post but.....oh well. Yesterday a new CJ-6 owner flew here to Leeward, to get some acro training in the airplane (by a non CJ owner, albeit a very experienced pilot). I chatted a while with him, and suggested he join RPA. He replied he already joined NATA (he also bought a T-6 as an investment, I informed him his CJ was a better investment). He had expressed an interest in Formation flying, and I informed him of our upcoming Waycross event. He still didnt seem too interested. I tried expaining the benefits of RPA, and flying and learning in a structured environment suited specifically to his airplane. After some prodding, he finally relented and said he didnt want to join us because of the noise factor on this list. He doesnt belong to the list but searches the archives, and stated that for every usefull post he finds he has to weed through thousands of lines of "Shit". This new guy formulated his impression of RPA based on the content of this list. One can go on to reason that a dedicated restricted site would partially alleviate this issue (which it wont, look at CJAA) but the fact remains that this is the face of RPA that most people first see. I was embarrased and explained that there is a lot more to RPA than this list, but bottom line is that the signal to noise ration has gotten to about 80/20, the latter number being relevant info. One thing that can really help is if your post has no redeeming value as a historical document, then post "Do not archive" in the beginning of the post. This will keep it out of the archives. (I believe this is how it works) I am just as guilty as the next guy but we all need to police ourselves. Ernie

    Subject: Re: Breakin
    --> Yak-List message posted by: Ernest Martinez <erniel29@gmail.com> This is from Zephr engines website, but most of it would apply for radial engines. THE FIRST FLIGHT: Your Zephyr engine has been test run including full power operation at our facility. A brief run to check for leaks and control operation is all the running required prior to the first flight. After this run, the engine should be fully cooled. Then taxi time should be minimized if possible. A normal but brief preflight runup is adequate. One mag check and one cycle of the prop no more than 200 RPM will minimize temperature buildup. Allow for a slightly rough mag check due to oil fouling. Power application for the first takeoff roll should be very gradual. Runway length and obstructions permitting full power should be reached as liftoff speed is attained. Airspeed and full throttle fuel afford the engine maximum cooling airflow. Full power should be maintained to cruise altitude for fixed pitch prop type installations. Four cylinder engines with constant speed propellers may climb at full throttle with RPM reduction optional. Higher power and turbo-charged engines may be pulled back to 75-80% for climb once obstructions are cleared and cruise climb speed attained. All engines should also be climbed at a relatively high airspeed once a safe altitude is reached. One hour is a good initial flight time. Cruise at 75% power. Check fuel flows, oil and cylinder head temperatures, alternator operation, carburetor heat, and leaning capability as is appropriate to your particular machine. If possible avoid power reduction to idle prior to touchdown. After the flight uncowl, or open cowlings as required for a visual inspection of the engine installation as well as check for leaks. If you have any questions, PLEASE CALL BREAK IN OPERATION TAKEOFFS: FULL POWER should be used for all takeoffs and maintained to a "safe" altitude. Most engines are certified for continuous 100% operation. A few have time limit maximum RPM restrictions which are noted on the tach as well as in the POH. CLIMB: As stated in the preceding paragraph, fixed pitch installations require full throttle in all climbs; and the lower powered constant speed installations are better off at full throttle. Cooling airflow and fuel for cooling are the keynote in climb, so it is best to cruise climb at the high power settings appropriate for your type of aircraft. No leaning in climb is acceptable beyond that which might be required to maintain smooth operation climbing out of higher altitudes. CRUISE: For the first 25 hours or so of break in it is best to operate at 75% power as much of the time as practical. On normally aspirated engines avoid high altitude operation where you cannot obtain 75% or you are running high RPM and low manifold pressure to do it. Normal precise leaning is acceptable provided all indications of a correct lean mixture are in agreement; EGT, TIT, CHT. Fuel flow and the engine is operating smoothly. If fuel burn is not critical to the particular operation, we recommend for the first 10-12 hours a fuel flow that yields an EGT 75-100 on the rich side of peak. If practical for the first 10-12, or better yet 25 hours, avoid abusive operation - touch & go's, slow flight, etc. OIL: We use and recommend Phillips 20/50 XC, Phillips Type M or Shell Mineral for break-in, except in Lycoming 76-series engines, which require AD type oil and LW-16702 additive. Change the oil and filter at 10, 35, and 60 hours. If you are not satisfied with the consumption level at the 60 hour change, advise us! If you have chosen mineral oil for break-in, you may change to AD at the 60 hour change, provided the consumption is acceptable. OIL LEVEL: It is common practice to run most engines as low as 75% of capacity. It is certainly never necessary to run a 12 quart system at more than 10. Filling the system generally increases consumption due to oil blowing out of the crankcase breather. Oil temperature is thermostatically controlled so 12 quarts will not run any cooler than 10. Heat is dissipated in the cooler, not the sump so quantity will not increase cooling. OIL CHANGE INTERVALS: WE RECOMMEND OIL & FILTER CHANGES EVERY 35 HOURS OR 25 ON NON FILTER INSTALLATIONS. AUTO FUEL: DO NOT USE AUTO FUEL IN YOUR ENGINE PRIOR TO 50 HOURS. IT WILL RUIN THE TOP END. We do not recommend the use of auto fuel at any time. If you do use it we recommend an occasional tank of 100LL in order to run some lead. We will not warranty any condition which may have been caused by or contributed to by auto fuel. ENGINE LIFE: The worst enemies of your engine are dirt, disuse and excessive heat. Lack of use can be detrimental as it can lead to corrosion from moisture and acid buildup in the engine. The aircraft should be flown long enough to have the operating temperatures in the green for at least 20 minutes every 10 days to 2 weeks. Ground running is not satisfactory. Pulling the prop through by hand is not only unsatisfactory but detrimental as it removes oil from parts without any possibility of replacing it. Dirt is kept out of your engine by maintaining a good properly installed air filter and a leak free induction system. Dirt is everywhere so basing on pavement does not excuse you. Changing the oil and filter is also eliminating dirt from your engine. High operating temperatures due to lack of cooling airflow and excessive leaning will shorten engine life. Excessive or rapid heating and cooling will also shorten engine life. Warm the engine up slowly. Apply power gently and slowly, particularly on the first takeoff of the day. If you must have full power immediately, bring it up gradually with the brakes on if conditions permit.

    Subject: non starter
    Martin If the engine will start and run on the boost coil,/start switch, the problem is not likely fuel,. I would be looking for a problem in the mag switch or the "P" leads. A simple test for these problems is to disconnect the "P" leads ( first chock the airplane and/or have your co-pilot handle the brakes ) then attempt to start. A common misconception is that the boost coil is a "shower of sparks", not so, the boost coil does not require the mag coil to produce a spark, it depends on the mag only for the points, rotor and distributor cap to direct the spark to the plugs through a late firing finger on the rotor. Good luck Joe

If fuel burn is not critical to the particular operation, we recommend for the first 10-12 hours a fuel flow that yields an EGT 75-100 on the rich side of peak. If practical for the first 10-12, or better yet 25 hours, avoid abusive operation - touch go's, slow flight, etc. <BR > OIL: We use and recommend Phillips 20/50 XC, Phillips Type M or Shell Mineral for break-in, except in Lycoming 76-series engines, which require AD type oil and LW-16702 additive. Change the oil and filter at 10, 35, and 60 hours. If you are not satisfied with the consumption level at the 60 hour change, advise us! If you have chosen mineral oil for break-in, you may change to AD at the 60 hour change, provided the consumption is acceptable. OIL LEVEL: It is common practice to run most engines as low as 75% of capacity. It is certainly never necessary to run a 12 quart system at more than 10. Filling the system generally increases consumption due to oil blowing out of the crankcase breather. Oil temperature is thermostatically controlled so 12 quarts will not run any cooler than 10. Heat is dissipated in the cooler, not the sump so quantity will not incre ase cooling. OIL CHANGE INTERVALS: WE RECOMMEND OIL FILTER CHANGES EVERY 35 HOURS OR 25 ON NON FILTER INSTALLATIONS. AUTO FUEL: DO NOT USE AUTO FUEL IN YOUR ENGINE PRIOR TO 50 HOURS. IT WILL RUIN THE TOP END. We do not recommend the use of auto fuel at any time. If you do use it we recommend an occasional tank of 100LL in order to run some lead. We will not warranty any condition which may have been caused by or contributed to by auto fuel. ENGINE LIFE: The worst enemies of your engine are dirt, disuse and excessive heat. Lack of use can be detrimental as it can lead to corrosion from moisture and acid buildup in the engine. The aircraft should be flown long enough to have the operating temperatures in the green for at least 20 minutes every 10 days to 2 weeks. Ground running is not satisfactory.

    Subject: M14P for sale
    I just helped a friend pull a 360 horse M14P off his Sukhoi 26mx. He upgraded to the M14PF is the reason for pulling it. It has 750 hours TTSN, Savage ignition harness, fresh annual conditional inspection, compressions 72-78/80. It has been A+P owned and operated for the last 5 years. It's in "good condition" according to Don. $11,000. contact me off list, please. Don has also made a couple of 1500 psi compressors that operate on 28vdc. He uses them to charge either his Sukhoi or his scuba bottles. $500 each They are small enough (almost) to fit in an Igloo cooler. Also, what is my MTV-3-250 (German) overhauled by MT 2/03 - no ad's now. 330 TSOH worth to any one??? Ok-OK - I bought Don's MTV-9-260 wide cord...mea culpa Thanks, Rick b

Hmm, my understanding is that the lenticular just identifies the presence of a wave and not necessarily of a rotor. OTOH, if there is a lenticular cloud present the flow is possibly great enough to cause a rotor if the terrain (ridge) is sharp enough. Sometimes you will see a rotor cloud (different from a lenticular -- looks rough and tubular and is much closer to the lee of the ridge, not standing above it) and know to avoid that area. The mountains of the Sierra Nevada have steep ridges on the eastern side and form wonderful waves and rotors (sometimes) when the flow is from the west-southwest. (Look for winds aloft in excess of 30kts.) As you fly toward the ridge from the east you will find yourself in alternating sections of lift and sink which get stronger as you approach the ridge. I use the lift to gain a lot of altitude (16,000' MSL is not too much in my book) so that I can penetrate the sink and make it across the ridge with plenty of altitude, the goal being to cross the ridge at least 2000' AGL. This much altitude keeps me clear of any rotor that might be present as well. It also means that I have plenty of altitude to work with if I need to turn away from the ridge. -- Brian Lloyd 2243 Cattle Dr. brian-yak@lloyd.com Folsom, CA 95630 +1.916.367.2131 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . . - Antoine de Saint-Exupery

Amen. About 20 years ago I was flying my Comanche eastbound across the Rockies. It was a clear day and I had a bodacious tailwind. (This is a hint.) I was at 13,000' (IFR just because) just crossing the ridge west of Great Falls, Montana, when I penetrated the rotor. (Clear air, no cap cloud, no lenticular, no rotor cloud.) I lost 2,500' in 15 seconds. (That works out to 10,000' FPM -- my VSI was pinned at 6000FPM down.). I estimate I pulled over 1G negative as everything that wasn't tied down, including my then 2-year-old son, hit the ceiling hard!. ATC thought that my transponder had malfunctioned as my altitude changed so rapidly. It puts the fear of God into you. -- Brian Lloyd 2243 Cattle Dr. brian-yak@lloyd.com Folsom, CA 95630 +1.916.367.2131 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . . - Antoine de Saint-Exupery
