I used to deliver freight into OAK at 0100 every morning, so I know what you
are talking about with regard to HWD. I never related MSA to anything other than emergency use. I see far too many posts in the ngs where the pilot is trying to include the MSA in the procedure, and it has no place in the procedure. YMMV. Bob "G. Sylvester" wrote in message .. .

Just because ATC says "Descend and maintain...." does not mean that you have to obey without question. I asked my CFI about descending when cleared for an approach. He said exactly what you said. Calculate your 500 fpm descent to arrive at the crossing altitude a few miles before you reach the fix. I did this on my checkride and got a compliment over it from the DE. He said he's used to students descending immediately even though they could be far far away from the fix. I gotta thank my friend Mark who flies for UA as he gave me a good way of briefing for this using the MSA. Use this sparingly, however, lest you be vectored 20 miles away while everyone else shoots the approach. Bob Gardner especially considering it was into HWD which is right underneath and overlapping the approach paths for OAK. Gerald |

YMMV. I know what you mean and usually if it is an emergency, looking at the plate, figuring out where you are and which way you have to go might be too late. My friend (and i guess the rest of UA pilots) simply use it to get an idea of the height of obstacles/terrain for descent planning. If the MSA is 1000' AGL, you are pretty free to descend anytime. If it is 6000' AGL, well you know where the terrain/obstacles are and you should take a closer look at exactly where they are and probably best to descend much later on in the approach. I guess the best example is you are getting RV to a fix. You are off of an established airway and the controller says "Cleared for the approach...cross XXX at 3000." The MSA gives you an idea when to get down in a safe manner. Agreed that it is quite basic without too much use. Gerald |
