Route for Southwest flights, Reno to San Jose?
Can anyone tell me what might have been the detailed route for our
RNO-SJC flight today, Mon 28 July, 1:00 to 1:55 pm (in terms of common geographic waypoints or GPS coordinates)? I'd always had the impression these flights departed RNO heading more or less straight west and passing well to the north of Lake Tahoe and even Donner Lake, then angling southwest toward San Jose; and it seemed to me that was what we were doing today, though with the fairly severe haze and smoke currently in the Tahoe area, I couldn't pick out any Tahoe landmarks (looking across the Lake this morning, one couldn't see the far shore even in the narrow direction). About half or a third of the way into today's flight, however, from 23,000 feet we saw an obviously large fire zone area (no visible fires, but large area of heavy smoke) almost under our flight path on the left side of the plane, and easily visible in the middle distance was what sure looked like Half Dome. I kept thinking we really wouldn't have departed that far east and south of a straight-line path from Reno to SJC, and that this must have been one of the less publicized fires in the region NW of Highway 80; but on the other hand we ended up (with minimal banking and turning that I could sense) coming up into SJC up along what I took to be Highway 101 from the south. Would our route really have passed that close to Yosemite? |

In case the URL goes stale, the flight path was due south out of RNO, then southwest to Merced, and then northwest into SJC (El Nido Five Arrival). John -- John Clear - http://www.clear-prop.org/ |

Would our route really have passed that close to Yosemite? I can only take a guess as to the exact departure/arrival routes they would have used, but, since I learned to fly at SJC, I do know that the prevalent winds favor using RWY 30L for turbojet arrivals about 85% of the time. This routing takes you pretty much SSW from RNO to slightly south of due east of Mariposa, then west to just south of Merced, past the San Luis Resevoir to Gilroy and then straight in to SJC. The "flow" into the San Franciso Bay area is rather complex. (You can see the flow diagrams by downloading the MS Word file at http://www.mtc.ca.gov/planning/air_p...ty-delay/3.doc The diagrams are figures 3-7 and 3-8. The approach into SJC is brings you in about 35 miles SSE of the airport and then straight in on a 303 degree magnetic heading. Using this, I ran a DUAT flight plan and came up with routing that, regardless of what departure from RNO would take you as follows: (Note, I'm using the aviation VOR (3 letter) and intersection (5 letter) names, followed by lat/lon, and then the nearest place name I found on the San Francisco sectional chart. All distances are NM - nautical miles.) FMG (N39:31:52 W119:46:06) - The Mustang (FMG) VOR is in the town of Sparks, Nevada and very close to the (in)famous Mustang Ranch brothel. It is about 6 NM ENE of RNO ELCAP (N37:41:09 W119:46:06) - You should be able, if clear, to see El Capitan out the left window as well as Half Dome. ELCAP is 111 NM south from FMG. HYP (N37:13:09 W120:24:00) - The El Nido (HYP) VOR is 7 NM SSE of Merced. TORCH (N36:58:46 W121:29:33) - This is 32 NM from SJC and between Gilroy and Hollister. Note that this turbojet route is 53% longer than a direct great circle route. Now, if you are not in a turbo jet, but in a small plane like I fly, the routing would me a lot more direct (5% longer than a great circle route): HUYJO (N39:14:56 W119:50:56) - NNE of Lake Tahoe about 5 NM east of Incline Village. SPOOK (N38:37:57 W120:15:51) - From HUYJO, you cross Lake Tahoe just north of Glenbrook and exit just west of Camp Richardson. SPOOK is in the middle of nowhere. LIN (N38:04:28 W121:10:16) - You've passed Mokelumne Hill and LIN is about 15 miles NE of Stockton. ECA (N37:50:01 W121:10:16) - About 7 NM SSE of Stockton SUNOL (N37:36:19 W121:48:37) - You pass over the Altamont Hills wind farm, south of Livermore, and are over the Sunol golf course. Hope this helps. -- Marty Shapiro Silicon Rallye Inc. (remove SPAMNOT to email me) |
