Waypoints are tooo closed... any help?

Featured Replies

Hi JD,my problem is that sometimes I miss a waypoint for just a tic of maybe 0.2nm, but still miss it and have ti return to get it. So why do I miss a waypoint? Weather wind is so strong! It doesnt matter if otto flys or a GPS driven AP or a FMC. Can I alter anywhere the area in which I have to be about a waypoint, so it will count as passed?Do I make any sence? I dont wanna fly holdings cause I cant make a waypoint close enough.Ciao, Torben.

Regards, Torben Hadler

departure procedures are the most crucial in making your waypoints count. but you have to be within 2 miles, not .2 miles to get credit. all other checkpoints you have to pass within 5 miles.even with a strong wind, i can come within 2 miles of a checkpoint in a departure procedure.how close together are your waypoints in your flight plan?

Sometimes FSNav gives me some 2 to 5 miles dist btween checkpoints to get from one airway to the other or arrival route. Sometimes the wind is about 120kt sidewind and I fly with mach 0.78 and - I get out of the 5 miles ckeckpoint radius. And when I fly with the FMC of a DF737 or PSSA320, the FMC calculates a radius turn by a checkpoint. So I fly a early curve so to get around a corner of maybe 90degrade or alike. If the wind is strong enough I dont hit the area of 2-5 miles a checkpoint. The best FMCs or MCDU try to not overshoot a waypoint and route and begin the curve early, but RC3 doesnt like that. Can I change the area of 2 miles to 8 miles?ThanxTorben.

i would say 2 miles between checkpoints is a little extreme.no you can't change the distance to "progress" a checkpoint.if this in a departure procedure, maybe you should check flex sid.

Torben,I don't know about the DF737, but on the PSS A3XX you can define a checkpoint as an 'overfly' checkpoint. I'm not in front of my FS computer at the moment but I think you click on the 'delta' (triangle) symbol then press the left LSK of the checkpoint you want to overfly. This means the aircraft won't cut the corner, but will fly directly over the checkpoint. Note that overfly checkpoints can make things worse, because the aircraft might have to make a tighter turn to reach the next checkpoint. It's just a case of try it and see.Having said all that, I've not had a problem with the airbus missing a checkpoint so far, and I don't use overfly mode.Ian

Torben,I highly recommend you remove some of the waypoints. You also should do some heavy cross-wind correction practice. One good way to see the wind-heading correction, let Robin fly the plane. Then you will get used to that. Plus, you can visually see your drift in FSNav and correct from there.

>Sometimes FSNav gives me some 2 to 5 miles dist btween >checkpoints to get from one airway to the other or arrival >route.The only times you should have checkpoints so close together is if you're flying a SD or STAR. If you're either maybe you should slow down instead of blasting through at mach .78. Just a thought. :)Sidney Schwartz [KPDX]Horizon Flights--flight plans and scenery for FS2002http://sidneyschwartz.homestead.com/index.html

You don't have to strictly follow the jetways. You can make a plan to fit your needs. We don't have free-flight as of yet, but it's getting close.Besides, FSNav puts in all kinds of random crud you don't need in there. Start with what it gives you when you use auto-route, then adjust for a more suitable plan.

Spoken like a true, "I'm in charge!", cave-dweller!! :-lol

The beauty of Free Flight. The pilots can file Around Memphis Center... :-lolLarry
