Flight Path And Related Issues
Robert99:
For those of you who are committed to the so-called FBI flight path, go to DropZone and take a look at Georger's post #57121 and my reply to it.
Chaucer:
If we assume the yellow map is accurate then, yes, 305 did pass west of PDX.
After it crossed over the Columbia from the east.

If there was no cloud coverage the crew would see PDX easily to the east..this is at 10,000 feet just after crossing the Columbia.

--- Quote ---For the record, Flyjack's red line can also be dismissed. At several points, the airliner is about 3 nautical miles from the centerline of V-23. Other things being equal, aircraft are expected to stay on the centerline of Victor airways and there is a regulation stating that. If the flight crew couldn't keep the aircraft on the centerline, then their autopilot certainly could. Even the simplest wing leveler in a Cessna 150 could do that.

That's not the case in the matter, they were given the sky in order to keep everyone safe. most regulations went out the door with this problem. I believe they are expected to stay within the boundaries, unless in controlled airspace. why have them 8 miles wide?
Unless authorized by ATC, to operate an aircraft within controlled airspace under IFR, pilots must either fly ALONG the centerline when on a Federal airway or, on routes other than Federal airways, along the direct course between NAVAIDs or fixes defining the route
Just because a simple route can be layed out certainly doesn't imply that's what occurred? none of the crew said anything about why they would be looking miles away from where they actually were, or mention how simple they could layout the path within several minutes..

It is certainly true that the airliner crew were told they could make any deviation necessary to V-23 and that ATC would keep other aircraft out of their way. But that does not explain why they were wandering so far from the V-23 centerline, particularly in the Portland area.
South of Portland, the airliner would almost certainly want to stay on the centerline of V-23 due to concerns with the MOCA (Minimum Obstacle Clearance Altitude) and MCA (Minimum Communications Altitude) among other things. In some segments of V-23, 10,000 is the minimum altitude that any aircraft could meet those minimums. Even in the Portland area, the MCA for the Malay Intersection is 9500 feet.
Just staying on the centerline of V-23 does not require a superhuman effort. If the airliner wanted to bypass Portland with what they thought was a bomb onboard, the west side would be the logical choice. Even now Georger has admitted that his sources, apparently including FBI agents, were saying 10 years ago that the airliner bypassed Portland on the west side.
