Actually they are not on center of V23 from Malay to Portland. slightly east of center.

I'm shutting the system down, and restarting it. I loaded a new upgrade to Portland PDX, so possibly the system is not functioning correctly. the new airport is very detailed and took several minutes to upload. I might need to restart the whole thing to insure the system has reset properly......

The temps will set as one. I only have to input the ground temps and it will automatically calculate temps aloft. I wish it did this for winds as well.

Here are two screenshots of the video....this is the proper configurations I fly...

I found the issue with the video. I had it on private....you should be able to view it now?

I can now view the video on Chrome and the two pictures on IE-11.

If you turn more to the east than the centerline of V-23, then your ground speed should increase further but the KIAS and KTAS should not change simply because of the turn.

I have never heard of something that required the setting of the ground temperature which was then corrected automatically to the temperature at a given altitude.  Even the Total Air Temperature shown on that gage must be corrected manually for aerodynamic heating.  That is, the Outside Air Temperature will be less than the Total Air Temperature by an amount which is a function of the aircraft's airspeed.

How do you manually change the TAT?

When I first purchased X-plane. I noticed only one setting for temps. I called them asking about temps aloft. they told me they were automatically set to what you input the temps at?

You can't manually set the TAT.  It measures a value that must be adjusted for the aerodynamic heating caused by the aircraft's speed to calculate the actual OAT.  In the case of NWA 305, the TAT had to be reduced by several degrees (I forget how many) to get the value that the NWA performance engineers in Minneapolis needed for their calculations.

I set the temps at 42 degree's....the TAT reads -9
I reset the temps to 62 degree's, and the TAT reads 4 degree's celsius..

Hominid always told me not to even bother with the TAT readings.

The Outside Air Temperature, which has to be calculated from the TAT readings in this case, is used in determining the True Air Speed.

I've shut the computer down since last nite. I'm going to run a couple checks, and then run another test. my main concern's will be KIAS, and KTAS.

It appears I have a problem with my throttle control as well. right in the sweet spot the speed will not hold steady. it rises, and falls. even after calibrating. I can manually apply thrust, or decrease through the keyboard keys F1, F2. this could be my problem with speed changes.

Lets see what happens....

I always found this post by Agent Carr interesting....

As I always tried to tell Blevins - the quote indicates one reason the FBI came to Dropzone. To do a FP analysis - free! They were already aware of the options available (ie. amendments to the FP vis-a-vis the money find). Of course Ckret never made his (the FBI's) 'objectives' explicit in a formal way. Whose objectives did Ckret represent, if any, or was it just personal on Ckret's part?

Blevins always denied there was any formal concern for the FP involved, on the FBI's part. How would he know!?  :(   On the other hand, Ckret said many times 'I am at Dropzone out of my own personal interest' and one of his primary points of interest was _ the integrity of the FP and DZ. 

So. Who believed what when in the Bureau? We have H's quoted interview from 1976 saying '...the new drop zone is now 12 mile north of Portland'. So, FP and DZ certainty was already being examined at least by some in the Bureau 4 years before the money find!     

We lack primary sources of info that might confirm or deny particular FP/DZ issues irrespective of what the Bureau thinks or wants, or any of it's agents think or want! And Ckret never said: 'We know how the money got to Tina Bar'!

 I ran two tests last nite from Seattle to the Battleground Vortec (directly over it) the times were consistent with each other. the average speed was 170 KIAS--195 KTAS.

Test #1 ending with 37:06 minutes, or 8:14:06
Test #2 ending with 37:18 minutes, or 8:14:18

I'm working on my cinematic movie making skills. here is a video of the new KPDX. it's in HD, but you need to set the quality on the video. full screen is the best view rather than watching it on this forum.....

Info re Don Kirlin and FAA clearance for 727 skydives:

From: You are not allowed to view links. Register or Login

Once he sets his mind to a goal, he's relentless. He soloed his first plane at 16, instructed at 18, and began flying corporate jets three years later. He flew in the Navy, got twin bachelor degrees in business and clinical psychology, and then an MBA, all from the University of Northern Colorado, and moved on to US Airways. In 1993, he asked the FAA to let him parachute from the rear stairway of a Boeing 727, like the infamous skyjacker D. B. Cooper, who disappeared over the Cascades with $200,000 in 1971. Kirlin shrugs his shoulders and grins. "I just wanted to do it because the only other person to do it was Cooper," he says. The FAA said no, unless he could prove unequivocally it was safe. A year later, he presented 6,500 pages of documents to the agency. He remains to this day the only person authorized to operate jumps out of the rear door of a 727.

Interesting, I didn't know they regulated how the jumps were made. I figured they did for stunts, so i guess that was considered a stunt...

I still think the closest anyone came to recreating the jump was the stuntman for the movie "The pursuit Of DB Cooper' he actually jumped from the stairs. all the others had the stairs removed....
