I don’t put myself as a very experienced simmer. But I know what I know (I think) so I wanted to do challenging flight from Kathmandu to Paro (VNKT>VQPR) - Plotted my flight plan with the below:
Things start to go wrong around PAGDA, below are the FL you need to be at, at certain waypoints (Followed correctly). I did this in live weather so literally couldn’t see anything. When you get around PR782 you hear the shout out “2500” “1000” boom your dead. Then I thought maybe I didn’t set altimeter correctly so I put it on clear weather which is 29.92. Nope - this time I didn’t crash but only because I could see the AP was physically about to ram it into the mountains. - Any help would be great but as far as I know these are the correct FLs for the waypoints on my flight plan via SimBrief.
Where are you getting these altitudes from? I didn’t check all of them but the posted altitude was +16000 for PR777. You plotted your flight plan, you aren’t using the published ones?
Thanks for the reply. Maybe it’s be then on Simbrief you have FL MORA DIS (FL is obvios. MORA is Minimum off route alitude) - that does say 16500 for 777, but why say 9900 for the BOGOP1A just above it? Maybe something I just don’t understand yet.
Nine days ago my world tour included a stop at Paro. I used the MSFS flight planning to set up the RNAV plan. I wanted to see the sights so I set the daylight and weather for maximum visibility.
About 10 minutes out I saw that I was off line and looking at a mountain between me and the airport. I took control of the plane and weaved around the peaks and put the plane into a dive in time to land. The passengers told me that they needed to go change their shorts, recommend that I be fired, and that they would never fly again.
Sorry - edited this as I missed your other comment.
So in this case you’d deduce from the STAR chart that the later waypoint has a minimum altitude required of 16000 and ignore any lower altitudes on the OFP prior. Not sure why the MORA is that low on this waypoint as the grid MORA is much much higher.
Not that I understand how to read these things, but it seems to me that beyond PR777 (till around PRO) you need to stay above 13500 feet? At least, that’s what I would do after reading this chart and seeing all the warnings. No, actually I would probably keep flying at 39000 feet and find somewhere easier!
Kind of makes sense! SimBrief doesn’t make a lot of sense though as it’s telling me to put the alt much lower than the actual real chart… What is MORA then? Is that if you stray off course?
minimum off-route altitude (MORA) values on customer flight plans in order to provide aircrew with important obstacle clearance information, in the event that the flight should deviate from its planned path.
And you may stray on purpose, avoid other traffic for example.
Yeah I gathered I’d need charts unfortunately. Is there a decent website? I know you can get hold of some for free but doesn’t seem a definitive place. SkyVector is pretty pants. Doesn’t really tell you much.
SimBrief is just giving you FL’s based on it’s anticipated/estimated vertical profile. I haven’t done a tonne of cross checking on this but it doesn’t appear to pay any attention to charted departure/arrival restrictions.
If you don’t want to use charts I’ve found generally the navdata in MSFS has mostly the correct altitude restrictions so you should cross check that with your flight plan for discrepancies then you can decide if you’re gonna need the chart.
