As a new (Test-) User of that program a warm "well done". However, questions remain. Yesterday, I was able to perform 2 short flights. For the meantime with voice-assistance of my copilot, who does a good job.

Now, on both flights the very far-from-reality-away instruction came from ATC while performing a (previous instructed) descend from FL350. They wanted me to (Quote) Slow to 200 knots or less (Unquote). And I just passed FL290 !! Having 300knots on my B777. Out of the fun of it, I followed the instruction.

• Glideslope became misserable, as I had to deploy flaps for that speed plus speedbrake before that, to eat up the 300kt down to 200kt  wich resulted in more fuel consumption lateron
• Time consuming of the approach became twice as much

I assume, I made some wrong settings somewhere.Cant find it 😞

Welcome Ron.

The only way that should have happened is if you were flying a STAR that had a speed restriction.  And 200 kts is usually only at lower altitudes.  If this happens again, please email me the P2A log file for the flight.  

P2A Log files are located in: C:\Users\<UserName>\AppData\Roaming\P2A_200\Logs where <UserName> is your PC user name. 
Portions of the path may be hidden by default, so be sure Windows Explorer has Show Hidden Items checked in the View tab.
 

In addition, if you're flying a Heavy jet like the 777, be sure that you have "Heavy" checked in your callsign setup in Config.  That should increase the 250 kts below 10000 ft restriction to 280 kts so you don't fall out of the sky.

From the FAA 7110.65 ATC Handbook, this is a portion of the speed assignment section:   (entire section here: https://www.faa.gov/air_traffic/publications/atpubs/atc_html/chap5_section_7.html}

1. SPEED ASSIGNMENTS

When assigning airspeeds, use the following:

1. To aircraft operating between FL 280 and 10,000 feet, a speed not less than 250 knots or the equivalent Mach number.

NOTE-

1. On a standard day the Mach numbers equivalent to 250 knots CAS (subject to minor variations) are:
   FL 240-0.6
   FL 250-0.61
   FL 260-0.62
   FL 270-0.64
   FL 280-0.65
   FL 290-0.66.
2. A pilot will advise if unable to comply with the speed assignment.

1. To aircraft operating beneath Class B airspace or in a VFR corridor designated through Class B airspace: assign a speed not more than 200 knots.
2. To arrival aircraft operating below 10,000 feet:

1. Turbojet aircraft:

1. Assign a speed not less than 210 knots, except for the aircraft as specified in subparagraph b above, or
2. Assign a speed not less than 170 knots when the aircraft is within 20 flying miles of the runway threshold.

1. Reciprocating and turboprop aircraft:

1. Assign a speed not less than 200 knots, or
2. Assign a speed not less than 150 knots when the aircraft is within 20 flying miles of the runway threshold.
