Hi,

I made few flights (FsLab A320) with Star approach. I'm surprised that after allowing me to fly the Star, the ATC gave me speeds and altitude commands during all the Star path ! In some Star there are sometimes some altitude constraints and speed restrictions. I think I set correctly Pf3. Just in case, find attached my last log.

Is there an option to avoid this ?

Thanks and Regards,

I see you are flying an A320 which is a jet transport I believe! The speed constraints in PF3 are final approach speeds so you should set up your aircraft preset to be the same for all jets. The reason being is that in the real world ATC do not know or care much about an individual jet aircraft's speed envelope unless it is Concorde or a heavy at max landing weight. So the speeds that are given during the approach phase are generic so to speak. They are given to maintain separation and to provide an orderly arrival sequence. And btw ATC can and do give speed restrictions that override a published speed restriction. In any event if you put the generic speeds into your jet aircraft preset you will find that you will more often than not meet those published speeds restrictions without much interference from PF3. In other words you should be already slowing down during the approach phase. I'm not saying that you don't but one comes across many sinners that complain about not being able to lock onto the localiser etc etc simply because they are flying too fast. This even applies quite often to well known youtubers and because they get away with it their followers think that's the right thing to do.

Anyway for a jet transport set your preset as follows to an approach speed of 160 ias. This will be the last speed call you get from ATC which you should maintain until about 6DME and thereafter slow down to your Vat+5. This will ensure that all previous speed calls will be in the ballpark. If you are planning a flight in a heavy that implies that you will land at max landing weight then up that to 170 ias.

"And btw ATC can and do give speed restrictions that override a published speed restriction."

Yes, I know that. The problem is that PF3 does systematically for speed and altitude during the Star.

"In any event if you put the generic speeds into your jet aircraft preset you will find that you will more often than not meet those published speeds restrictions without much interference from PF3."

It seems that whatever the speed entering the preselection of the aircraft, PF3 does not seem to take account. Btw, of course I had done it. Maybe this is not reflected in the Log file attached !? No ?

"In other words you should be already slowing down during the approach phase. I'm not saying that you don't but one comes across many sinners that complain about not being able to lock onto the localiser etc etc simply because they are flying too fast."

Yes of course but if you allow me this argument seems irrelevant in the case of a published approach and managed by an Airbus or a Boeing FMC even so of course the pilot must always be ready to take control to ensure to proceedings. At this time PF3 begins nagging from the beginning of the Star with "speed 320" 240, 220, and so and so...Can you see that also in the Logs file ?

I think, please if it were possible for the developer, it would be ideal to have the choice of being managed more or less or not by Atc during a Star approach. For example this possibly be an option on or off, or better by a percentage chance.

Thanks and Regards,

Just to mention that you can hit hotkey 1 (or use the appropriate voice command) to request clearance at pilot's discretion and you will not be managed at all. I think this request is available even before you have been handed to Approach.

Or you can tick the "STAR" Option which automates the hotkey 1 request. In that case you should not include the STAR waypoints in the flightplan loaded into PF3. The last waypoint should be the STAR entry. You can then fly the STAR without interference by PF3.
And if you want to be surprised with some percentage chances you might want to take a look at the PF3 Randomizer.

Thank you Ralf, did the trick ! and yes I know, I have the Pf3 Randomizer

Thanks but this request is not available before to be handed to Approach...Finally Ralph solution was the good one.
