REFLECTOR: Altitude

Mon Sep 19 19:50:35 CDT 2011

Kevin, 

In case you missed some of my previous posts... USE A KOCH CHART!  It is the most accurate gauge of aircraft performance that I have every used (with reference to density altitude performance). 

Use your normal sea level numbers and adjust according to the chart. 

It works!

              Hi All,
    Thank you so much for your help on this topic also.
    With no standard "runway/performance" chart to ref you all with your    experience have been exceedingly helpful and I am grateful for the    help.

    Thanks again,
    Kevin Baker

Hi Scott

I assume you run a catto?

If so what pitch/length?

That is great information

Thanks

 Ruben,

          I've flown a STD RG with a IO360 200HP 500 hours between          Grants, NM and SFO, flown around Colorado, Utah, Arizona,          Calif, etc..   Lightly and loaded and gross loaded.. 

          The Velocity is a great cross country machine once your in the          air.  I've had mine with the IO360 to 19, 000.  It was fine          but I was certainly near or at its ceiling at that altitude.           With a Lightspeed EI.  I regularly fly between 10,000 and          14,000.  You need to bring your mining equipment fly any lower          on many of the routes around here.  

          The weakness in the V, at least with normally aspirated engine          and fixed pitch prop is runway length at high density altitude          airports. You can and will use a lot of runway.  Be conscious          of the DA.  If you are going to travel at or near gross          weight, plan on early morning departures.  Its a smoother ride          anyway in the mornings so  you get two birds with one stone.           Be aware you can easily land at a filed that you don't have          the power to take off from at the same weight and temperature.

          I use the Aerox oxygen system and it works great, but I really          like the Mountain High demand system.  If your going to use          O2, I would highly recommend getting a Pulse Oxymeter any of          the clip on oxygen meters to monitor your(mainly) and any          passengers.  Especially if you don't have high altitude          experience.  Its really tough to recognize oxygen deprivation.          

          I live on the I40 corridor and you can easily fly this route          at 10,500, though I don't.  You can do 9,500 most of the way          with a short climb east of ABQ and around FLG..  Lots of          airports along the way.  There is no reason to fly so low in          the V.  12,500 & 13,500 are easily done and the climb rate          to those altitudes during cooler weather is more than          adequate.

          Your going in the fall-winter season so that will help a lot          towards the density altitude situation.

          So, be aware of DA.  If its warm, depart in the mornings if at          all possible.  If you have to stop for gas in the middle of          the day, look for long runways.  7,000+ is not unusual if the          altitude is above 6,000 ft. 

          Fly one of the main routes, I40, I80, etc..

          Fly a minimum of 10,500 or 12,500 west bound, the higher the          better.  Its smoother usually. Also get flight following from          ATC.  Nothing like having somebody outside teh cockpit looking          out for you and most of the controllers know the terrain and          will prompt you for the correct response if your pushing the          envelope.

          And have fun!!  There is no where more beautiful or awe          inspiring to fly than the mountain west!  Visibilities are          100+ miles and the vista's and sunrises/sunsets will take your          breath away!

          Scott

Hi all, 

I am planning a trip to the                      West coast from the East coast and it happens the                      Rocky Mountains                      are in the between. I have a SE-FG with an IO-360                      180HP. I wonder if anyone has any experience                      climbing to 16,000ft (the max. ceiling) with this                      type of configuration and what performance is to                      expect climbing and cruising at that altitude. I                      can climb fine to 9,000ft or 10,000ft but never                      gone above. I have also looked at the Aerox oxygen                      system, it seems very compact. The other issue                      would be taking off at fields that are at 7,000ft.                      Certainly they have long runways.

So, I wonder if there is                      anyone in that area who could share their                      experience in this type of adventure.  

Thanks.
