Gentlemen:What series of events must be in place (or not in place) for the Evil "Ammended Altitude Command"?With NOTAMS enabled, I am requested to "ammend" my altitude from FL290 to FL240 while still climbing TO FL290. OK sounds fair, so I do it! I'm still 100nm+ from Airport SCEL. Maybe further...Then along comes the even more dastardly "Ammend your Altitude" some more down to Alt. 190! And then Alt. 140!...(Can you say "Roller Coaster Ride"?) My Corporate passengers are now looking for another Corporate Pilot on their Cell Phones. (When they aren't vomiting up their Lobster and Chardonnay all over the "Rich Corinthian Leather Seats".)But, I can't descend because there are a whole bunch of Andes Mountains down there - so I politely decline the invitation. Naturally, they insist. Again!Naturally, I refuse. Again! At least until I cross the Andes in Chile.Hint: Mountains do NOT move very far when you run into them. It is better to AVOID them at all costs.Naturally, Bill Stevens tears up my license and I'm out of a job!Does RC work for Car Wash towel guys?:-spacecraft

I found out what NOTAMS means:It means: You can't fly in the Morning! After lunch only. LOLYou need a Donkey Guide here in Chile, Mac?:-spacecraft

Capt,I didn't really understand your first post, and I definetly didn't understand your second post, but I'm glad everything is ok now? ;o)Subs

Is this a short flight where departure and approach are very close? Is your climb rate and chosen cruise altitude appropriate? Descent rate?For your chosen cruise level for the flight distance it almost sounds like your climb and descent performance performance is below what is expected.It is not unusual in "problematic" terrain like around the Chilean coast - if I have your area correct - to find steep descents. We've heard about SCEL before.RC has a terrain database from some third source but it may not be of high resolution enough to guide you through passes via vectors. It is best to choose charts of the area and choose your plan using published airways and STARS which offer thed best path through rough terrain. Autorouting in flight planners do not consider MEAs on airways as far as I know. For approach use charts and choose an IAP to do your own navigation. In the real world radar may be blocked by terrain in certain sectors once below the MEA.

Ron,I'm still quite amazed by how accurate this program (RCv4) is, and I enjoy posting funny notes whenever I find something unusual that stumps it. The program however, is only as accurate as the info. fed into it.Usually the culprit is mountains and the irregular geographic features surrounding them. In this case it was the central Andes of Argentina and Chile: Specifically the mountain named Cerro Aconcagua at 22,834 ft. to the north east of airport (SCEL) Arturo Merino Intl.The Add-On FS Global 2005 has it as high as expected.Flight Sim, and FS Navigator list this terrain at only 15,000+ ft. with the highest obstruction at at mere 9,200 ft. WOW! what a difference! No wonder I was told to "descend". I would have been underground.Only by changing the info. on the departure page am I able to have a safe flight as expected.Thank you for your notes. Can I have my Pilots license back?:-spacecraft
