Notes for Using the KPSO200006 Web Cam Looking at KPSO
Although all information on this site is belived to be accurate and timely, there is no guarantee for that. Always verify current conditions through official sources such as an official briefing and the local AWOS. In addition, every pilot should consider current condtions and do all of their own flight planning before considering a flight into PSO.
Location of the Camera
The KPSO200006 web cam is located on the side of Oak Brush Hill, looking north to the Pagosa Springs Airport (KPSO). The camera is approximately on the 200 degree radial from KPSO at a distance of 6 nm or 7 statute miles. It is at an elevation of 7,950', or about 300' above the PSO field elevation. Click on the image to the immediate right to see the camera location on the RNAV-A approach plate for KPSO or on the picture to the far right to see the full size image from the web cam.

Landmark Elevations and Distances
The image to the right shows some of the landmarks in this view with their elevations and distances from the camera. All distances are in statute miles, the same as reported by the AWOS and shown on the approach plate. The unnamed hill in the lower right is 1.2 miles away and a good way to judge visibility when the airport is near minimums. Be aware that this is mountain weather, and the visibility near the camera may be very different from the visibility at the airport.

Thoughts on Flying the RNAV (GPS)-A Instrument Approach
The approach indicates that a circle to land to runway 19 is NA (not authorized) at night. When the weather is near minimumns at PSO, you should consider the circle to land to runway 19 not advisable any time because of typical local weather patterns
Most often, when low ceilings and weather arrive at PSO, it is with southerly or southwesterly winds. The orographic lift that these winds cause with the mountains to the north, almost always cause worse ceilings and visiblity north of the airport than south. Many times when the approach is near minimums, a straight into runway 01 can be made, but low clouds prevent a safe circle to land to runway 19. Knowing this, pilots should strongly consider planning their final leg descent rates for a stabilized descent to airport elevation at RW01, rather than a descent to the MDA at that point. Planning a descent to the runway, gives enough space when the runway appears at the MDA to side-step to a straight in final to runway 01.
The descent rate per nautical mile from DUGNE to RW01 is (10,300'-7660')/7nm or 377 ft/nm. This is a descent angle of 3.6 degrees, only slightly steeper than a normal ILS at 3.0 degrees. However, high density altitude and the typical tail wind on this approach can significantly increase ground speed, and therefore the required descent rate, on the approach into PSO. If we use typical, final-approach, indicated airspeeds for Category A, B, and C aircraft at 9,000' (mid-point of final descent), 30 degress C., an altimeter of 29.60 in, and a tail wind of 10 kts, we get the following table of descent rates:
Although the parameters used in this example push ground speeds to the high end, remember that ground speed is almost always higher than indiated airspeed on this approach. The descent rates shown are large enough that careful planning may be needed. Obviouly the MDA must be respected, but if you plan your descent to field elevation at the end of the runway, you will have a much better chance of being able to land if the airport is above minimums. Calculate your own ground speed (GS) in kts and from that, calculate your required descent rate for the final segment of this approach as 377*GS/60 ft/min.
