Oops, thats the problem of only using Jeppesen for my guesses!
I cant read the heights on the Topo, but it looks like 6900 feet for twin peaks, so that would be an obstacle measured from the adjusted runway end. Then it would depend on how much of an impact it had on the takeoff weight. If the impact was too severe, then i would add the 6400 feet obstacle straight ahead, and define a turning point back to the right that would increase the track distance to the 6900 feet point.[/quote]
The twin peaks are 6,900, plus vegetation. The ridge line to the west is 7,200, plus vegetation. Byond the 7,200' ridge line is a small lake then the terrain slopes up quite rapidly to almost 10,000.
Almost forgot, as i operate under FAR91, all that i legally have to do it look at the obstacle, decide that i can clear it, and yee haw, advance the power
Exactly!
