Did you already try to set no Approach Speed in the preset (leave it to "- Select Approach Speed") and set 40 or 50 on the "Ini Tweaks" page?

For me that works as intended both for very low (10 kts) and very high (100 kts) entries. I've been flying an Airbus though so there might be a bug with props.

You can also try maxing out the ini at 100 and see if there is any effect.

Just tried that, same result. Reduce speed to 140 20 miles from airport.

I don't have a solution for your problem (the logs show that your settings are correct, but I see the speed call, too), but a question:
Does the Connie really need such a high speed? With the CotS B377 I have set App Speed to 130kts, for all my other props even slower.

The problem is, and aircraft like the connie which is very slippery, either can descend at a good rate, or slow down, it can't do both. So if ATC tells me to descend a few thousand feet and a minute later tells me to slow from 210 knots to 140 knots, miles from the airport, this creates an issue, since I can either do one or the other. I start to descend and am constantly nagged about my airspeed. Once I start descending it is very difficult to slow down. I have copied an pasted the instructions from the PF3 manual, and my problem is these instructions do not work properly.

If PF3 behaved the way the instructions say it should, I would have no problem at all.


Final App Speed is the minimum final approach speed ATC will give
you during your final approach. With this option turned OFF (not
selected) the Final Approach Speed defaults to 190 knots for jet
aircraft and 140 for props. With this option selected and the adjacent
value set to zero PF3 uses the Flaps-Up-Stall-Speed read from your
Aircraft.CFG file. If you set it to any other value other than zero, PF3
will add this value to your Flaps-Up-Stall-Speed.
Please Note: This Final Approach Speed will be overridden should you choose
to use the Final Approach Speed entry provided in Flight Profile Presets[/b]


The underlined text is not the way the program is working for me.

By the way, where are you setting your approach speed, in the profile or in the ini for the B377?

You haven't said whether you tried my suggestion. To set the ini tweak to zero "and" checked. NB the speed set in the aircraft profile is not the slowest speed. It isn't the landing speed. It's at least Vat+30. So you need to calculate what your Vat speed is and add 5kts. More in windy conditions. So assuming a Vat for the Connie of 110kts then your profile speed will be 140kts. On the other hand are you leaving yourself enough time to slow down anyway? One gets the impression that you are at cruise speed and then suddenly slow down to final approach speed. Which is not how you would fly the Connie. I think you need to bring the speed back much earlier as you would in real life. The Connie approaches and lands quite slowly and in reality ATC would not issue you with a speed reduction. If anything they would if the airport was busy ask you to keep your speed up!
The ATC speed calls are there primarily to slow down jet transports during their final approach for separation. The speed in the profile is the last ATC call before you slow down to your Vat speed. The speed at which you cross the threshold of the runway. (Vat=Velocity at threshold). Usually the Vat speed is Vat+5 for normal operations. ATC usually allow you up to 6DME to slow down to Vat from their last call.

In your case, 140kts seems about right actually. That gives you plenty of time to slow down to Vat+5 for the actual landing.

For a jet transport the profile should be set to 160kts. That allows ATC to slow you down to 180 to capture the localiser, then at about 11DME ATC will call 160 and at 6DME you slow down from 160 to Vat+5. The Connie is much slower so an ATC call of 140kts at about 10 miles from touchdown is not amiss.

Tried the setting omo tweak to zero and checking, same problem.

We are still going in circles, the instructions for setting approach speed for PF3 do not work. Period. If I set an approach speed of 180, I want an approach speed of 180, not 140.

Well I expect Dave will look into it but the approach speed settings do work. That said I don't think you would set 180 kts as an approach speed for the Connie it's way way too fast. After all a Connie is a prop airliner. As I said it's not the landing speed. Most likely Vat for the Connie would be around 90kts. So requesting 180kts for the profile would be utterly wrong anyway. If there is a limit of 140kts for props with regard to the profile then that shouldn't be changed as you would not be flying much faster than that within the TMA in a prop airliner. Even slower in a light a/c.
