 Posted: Tue Jul 01, 2008 10:53 am Post subject: Some changes for the July newsletter |
 |
|
Guys,
Sorry about this, but when I finally got around to re-reading the July newsletter (it was posted on the two web sites several days ago), I found that the article on my testing the new wing tips has some things I need to expand on or even re-write. So for now, on page 14, the second paragraph has some slightly misleading information as it is currently written. Below in red ink, is how that paragraph should and would read if I were writing it today. I guess the next round of "suds" is on me - meaning either I will buy the round or you can pour your beer on me. Bummer.
Blue Skies,
Buz
Here is how I wish I had written it (changes in red):
Due to the really “bumpy air” for my second flight I hesitate to give much validity to the following data, but for what it is worth, Vy plotted out to be something like 83 mph or so. (Note: this is much lower than the Vy normally seen for the regular wing Lightning, and maybe should be taken "with a grain of salt" because it is based on only one flight on a really bumpy day.) I gathered this data by timing my climbs at various speeds to climb 1000’. Obviously it is hard to hold a steady climb speed in the bumpy air and I could feel a “kick in the butt” climb increase or decrease as I flew in and out of thermals. As Nick and I have seen in other Lightnings and Esquals, there seems to be a second Vy at something like 115 for this wing. (Many of you probably found the same thing on your Lightning with two Vys of 100 and 115 if you actually did lots of Vy plotting during your phase one testing). I fly my airplane taking advantage of this situation by using the 87 Vx after takeoff (until the end of the runway) and then transition to Vy of 100. If I am going high for a cross country flight, I then transition to the second Vy of 115 for a cruise climb. Both numbers result in something above 1200’ per minute initial climb rate for N31BZ. But remember that I live close to sea level.

Hi Buz,
I recommend that you just make the edits to the newsletter and
re-post the edited newsletter on both web sites. It will be read and
re-read by any number of people for a long time, and there's no
substitute for putting the right info where people will find it.
If you like, you can add a little note to the article that this is
Revision B, so that readers can tell the two articles apart.

hugh:
Good suggestion, Buz is a step ahead of you on that one; (just like all Air Force pilots are....)
I'll post the latest revision tonight on www.jimslightning.com
