    Rod, quick question. Doing this (full throttle) run up, are you suggesting we do this in place of the usual 1700-1800 RPM run-up where we check the mags, or is this in addition to? If in addition to, would you do this before or after the mag check? Thank you!

    • @Flight-Instructor
      @Flight-Instructor  ปีที่แล้ว

      Greetings Michael:
      I think you are confusing the phrases, "full throttle runup" with "using full throttle in the runup area to set the mixture for a high altitude takeoff." You only need to use full throttle to set the mixture for best power before takeoff. The typical runup where you check the mags, etc., is still done at the recommended RPM in the POH. Please go back and watch the video again to get the nuance in the narration.

Is that right?

      Yes, do the runup first and do it at the appropriate mixture settings which typically involves a little learning to prevent plugs fouling (if appropriate). The use of full power in the runup area is done after the lower RPM runup to "approximately" set the mixture for best power on takeoff.

    Lots of good information but you missed one point about high density altitude flying, that is starting the engine. I used to be with Black Forest Gliderport in Colorado (elevation 7200 feet) and we'd often have pilots fly in to fly gliders. They would try to start their engines only to have them start, belch black smoke and die from flooding. One of the instructors would usually go help them get their engine running. One day this guy in a Baron got one engine running and was having the other one refusing to run after starting. I went out to help him but he informed me that he didn't need some Cub pilot to tell him how to fly. He cranked on it until he finally burned up his starter.

    • @Flight-Instructor
      @Flight-Instructor  7 ปีที่แล้ว +3

      Thanks, JS: It's true that most Cessna takeoff charts show takeoffs at different pressure altitudes, but they also show four to five temperature ranges for each pressure altitude, too. So you wouldn't need to calculate DA directly since variable temps above standard are part of the chart. Does that help? If not, then send me a copy of the chart you're using to: rodfly9@rodmachado.com and I'll have a look.

  • @jjohnston94
    @jjohnston94 4 ปีที่แล้ว

    How do you lean for a go-around when arriving at a high DA airport? You don't have the luxury of being able to do a full throttle runup first. Just leave it at the cruise mixture setting? Or maybe get down to pattern altitude and do a full throttle run when you're 10 minutes out?

    • @Flight-Instructor
      @Flight-Instructor  4 ปีที่แล้ว +2

      Greetings JJ94:
      That's an excellent question. If you have the mixture set for a cruise at a high-density altitude (say, 10,500 feet) and descend for landing at an airport having a lower density altitude (say 5,000 feet for this example), then you certainly should reset the mixture before landing. It's entirely possible (depending on the difference in these density altitudes) to be on final, attempt a go around and have the engine sputter or fail with the application of full throttle (once again, depending on the difference between the two altitudes above).
      So here's a general rule to follow. When leaving a cruise altitude and before entering the traffic pattern at your destination airport, move the mixture control forward one-half of its "present" aft travel. On the downwind leg, you can test this mixture setting by smoothly applying full power then reducing power to the pattern setting again. If the engine doesn't sputter or cough, you've got the assurance needed to know that a go-around is possible with that mixture setting. If the engine sputters or coughs, then move the mixture control forward one-half of its "present" aft travel again. And, of course, upon going around, you can readjust the mixture for maximum power at the appropriate time.
      As an addendum regarding the go around, it's very very rare to have a normally aspirated engine (that's not being fed by an electric "boost pump") quit because it received too much fuel. Engines can handle a lot of extra fuel when operating at full "throttle" settings. On the other hand, an engine can easily sputter or quit if it doesn't have enough fuel regardless of the throttle position.

    @craigwall9536 4 ปีที่แล้ว

    Well, you _almost_ covered the case where you've got more thrust than brakes during the run-up; those of you with 1947 Ercoupes and factory brakes know what I mean...
    Since I've got full time EGT and CHT for each cylinder and they all run pretty close, I just 1) lean during taxi to the point that when I apply full throttle for takeoff it sags noticeably; then I know I need to enrichen but that I'm already on the lean side of peak. 2) I richen to get max power for takeoff by feel and sound, but 3) I've got EGT and CHT to watch during initial climb out so I don't get into the dangerously hot part of the engine operating envelope. That 15% automatic enrichment is great if you aren't monitoring temps, but if you are it's just throwing fuel away if you know you for sure you can stay out of the hot zone.
    You can do this all by feel if you KNOW the mixture distribution is even, and you can't know that unless you have temps for each cylinder. As an extra bonus, I go wide open throttle on takeoff and for the rest of the flight I manage power with mixture and carb heat- that is to say, I lean to drop the RPM to the bottom of the green in cruise climb and keep coming back after leveling off. Then if I want to climb after that, I richen NOT with mixture, but by pulling carb heat.
    This is a safe technique but not one most people would use because in cruise I'm running "acceptably rough"- which is a state where shutting off one mag gives a 200 or 300 RPM drop. Then pulling some carb heat jumps the RPM up about 200 RPM and without changing anything else, you get a nice cruise climb.
    In cruise I'm shooting for 1.316 times the max L/D IAS (best range speed) because THAT speed- the Carsten Speed- is where you get the most _speed_ for the _least drag._ It's NOT max range speed but it gets you there while you've still got daylight. In fact you can make up for lost time by going high to get the TAS up and by skipping an intermediate fuel stop since the fuel burn is so far down.
    .
    Some will object that leaned that much takes you out of the MAX ECONOMY mixture region, and it does- but I'm burning less than 4 gallons an hour with a C-85 and contrary to the old conventional wisdom, it doesn't "oxidize" the valves. CHT is the only temp that actually matters. I find that the power adjustment using carb heat is much easier than using a sensitive mixture knob since it takes much more travel with carb heat to get the same change. (All this should take into account the winds aloft- I lean much farther going downwind since a really puny power setting keeps you in the air longer so you take advantage of the favorable wind. Going upwind, I don't get quite as stingy with the fuel burn... you want to speed up a bit since it decreases the time you're penalized by an adverse wind.)
    One last thing: if you want to start leaning below 4000 ft, note the density altitude given by the airport weather recording and just climb however many feet are required to make 4000 (which in Texas is often pattern altitude)...OR, you can add carb heat as soon as you clear the terrain to give the ENGINE a 4000 ft density altitude BEFORE the airplane sees 4000 ft of density altitude. If that's not clear, I'm saying that carb heat lets you operate the airframe and the engine at two _different_ density altitudes simultaneously...which is _sometimes_ useful.
    Bottom line is, I go wide open throttle at the start of the takeoff roll and never retard it until I'm on downwind. That reduces "pumping losses" against a tilted throttle butterfly plate. Every other power change is done by mixture or carb heat. You might find my engine roughness a bit disconcerting, but if Peter Garrison could regularly cross the Atlantic in a homebuilt using the "acceptable roughness" rubric, it's good enough for me. And my engine loves it- operated this way, my CHTs stay down around 350F and there's not a spec of carbon fouling to be seen- you can easily double your TBO this way.

    • @chester8420
      @chester8420 3 ปีที่แล้ว

      Interesting that you are controlling engine power output with fuel, not throttle. Like a diesel engine. I have never tried that. Also since it is full throttle and not pulling vacuum, there's no loss of energy there either.

    • @clarkstonguy1065
      @clarkstonguy1065 2 ปีที่แล้ว

      Very interesting dissertation. If we were talking about modern engines, I would probably frown upon the concept of using carb heat as a substitute for throttle. However, given the fixed ignition timing in our Lycosaurs, you may be on to something. I am really wondering here if leaned to the point of roughness on one cylinder if carb heat actually may be more effective for smoothing out the combustion in the worst cylinder than actually richening with the mixture knob. Obviously it results in less power at full throttle than using the red knob would provide. And, don't try this at high power as a hot mixture is much more prone to detonation - so be on your game if using this trick as a substitute for altitude in order to get below 75% power for "safe" aggressive leaning!

    Or, better yet, if you have a engine monitor, pick a cylinder and note the EGT when taking off at sea level, probably somewhere between 1200 and 1300 degreees. On your next high density take off, lean the mixture and match the EGT on your chosen cylinder and lean in the climb. You will have max HP from take off to level off. Simple eh?

    • @Flight-Instructor
      @Flight-Instructor  7 ปีที่แล้ว +3

      Chris James The EGT value for a normally aspirated engine during sea level takeoff should be 1200-1250F. For a turbo engine it’s a little higher...1300F. This assumes the engine’s fuel system is set correctly and operating normally.
      If your mixture is set correctly for the actual density altitude, the EGT will be at the above values for takeoff. Lean during the climb to maintain those values and you will have good power and adequate cooling throughout the climb. Of course, all this assumes you have an engine monitor for accurate EGT/CHT readings.
      FWIW...I live and fly above 5400’.

      Yes, that accident was more than just a leaning issue, but setting the mixture improperly was a major contributor. With the density altitude the day of that accident, that 165hp Stinson should have only had two onboard, instead of four, and a reduced fuel load. Even a 182 under those conditions would have an issue. High DA’s are not to be trifled with, especially in heavy, underpowered airplanes.

      Rod Machado I learned form the best ;). I watch practically all your videos though this is my first comment. You are responsible for over 30% of my success in getting my PPL a month ago.
      PS. I watched your debate with J. King Loved it. Oh.. I got me some pine freshener, (the correct way)

    Yeah I thought I was reading that wrong. The term "High density altitude" should be changed. Firt time i read it i assumed that there was HIGHER density at altitude not lower. This used to be refered to as an airpocket where there would be pockets of lower density air during flights and the plane would suddenly lose altitude a few hundred feet.... this should be reworded..high density altitude just doesnt explain ...lower pressure than expected at altitude.

      Greetings Ryan:
      Yes, I do understand your confusion. But that's the way the term is correctly used in aviation.
      Best,

    If you don't want to have to lean your engine in Leadville Colorado, elevation 10,152 feet then get a jet engine or turbo prop engine as the fuel governor will lean it for you. You have no means available to lean a Jet or turbo prop engine.

    Hi, Rod, This video was very helpful, but then just in the middle of it, you made a comment that distracted me from your video so that I didn't want to watch any more of it until I wrote to you. You said, "It makes me feel as uncomfortable as a Border Patrol Agent at a 5 de Mayo festival."
    I happen to have Mexican family members that do not have any problem with the US controlling its borders. According to the following article from a writer in the border town of Nogales, Arizona, half of all border patrol agents are Latinos. Yup, half:
    www.theguardian.com/us-news/2016/dec/12/mexican-american-border-patrol-agent-vincente-paco.
    And they don't all hide out during 5 de Mayo celebrations. ( Read the page of the Nogales Arizona 5 de Mayo committee acknowledging assistance by the US Border Patrol, among others.)
    bordereco.com/events/2013/05/08/scc-cinco-de-mayo-celebration-hugh-success/.
    These topics are very complex, and very distracting.
    Were you trying to help Mexican Americans practice recovering from distractions from an Examiner during Practical Test?

      E Simm c'mon man, don't be so sensible. Nowadays you can't joke about anything without someone getting offended.

      I think Diego said it best in the comment below. But I do thank you for that comment referencing the video itself.

      Thank you, Diego. That was a harmless comment that I've use in audiences all over the US and never had one person feel offended. This sensitivity is why Seinfeld, Leno and many other comics no longer play at colleges and universities. Our colleges and universities have taught people to be easily offended at the silliest of things nowadays. I sure do appreciate your taking the time to post your comment, too. That means a lot to me. And, for the record, I"m half Portuguese and half German, which explains my insatiable desire to take over a country and then go fishing.
      Best,
      Rod

      ​@@Flight-Instructor Hello Mr. Rod. Coming from the "future", and it seems like its getting worse. I know you only focus on aviation but it appears to be that more and more industries and cultures in the West are teared apart by this new ideology also known as "DEI". Idk what is this reality, whether its 1984 or Twilight Zone.
      Oh, and thanks to reminding me to "pull back on the stick" in Flight Simulator 2004. Microsoft made a grave mistake making the tutorials not as comprehensive as it used to be for Flight Simulator 2020.
      With highest regards,

      No one else bu you're offended. In fact people like you prolly should've got internet. You're one of the reasons why Western society fall apart.
