I haven't see the "Rotation Speed" used, but I can confirm what has done wonders for me is the simple addition of the following to the "Reference Speed" section (you can set this to any speed you want depending on the size of the aircraft);
takeoff_speed = 140.0 //Knots True (KTAS)
Thanks, updated my models with this and it seems to work indeed: tested B738s and 32S, they seem to make 1500 to 1800m take off runs.
I spent some time yesterday to dig in the [GENERAL] section of the aircraft.cfg:
atc_type = "TT:ATCCOM.ATC_NAME BOEING.0.text"
atc_model = "TT:ATCCOM.AC_MODEL B737.0.text"
icao_type_designator = "B738"
icao_manufacturer = "BOEING"
icao_type_designator and
icao_manufacturer are used for model matching with online AI (along with the
icao_airline entry in the fltsim.x sections). They must be
ICAO official codes.
atc_type and
atc_model are used for ATC audio text-to-speech. You can pick any entry in your localization file (mine is:
(MSFS install dir)\Official\OneStore\fs-base\en-US.locPak).
atc_type is for the manufacturer,
atc_model is the Ac model itself.
Here are a few samples (not all were tested yet), some can be counter intuitive with the need to use silences (=blanks) when the manufacturer name is repeated in the model name:
atc_type = ""TT:ATCCOM.BLANK.0.text""
atc_model = "TT:ATCCOM.AC_MODEL SF34.0.text"
icao_type_designator = "SF34"
icao_manufacturer = "SAAB"
atc_type = "TT:ATCCOM.ATC_NAME MCDONNELDOUGLAS.0.text"
atc_model = "TT:ATCCOM.AC_MODEL MD80.0.text"
icao_type_designator = "MD83"
icao_manufacturer = "MCDONNELL DOUGLAS"
atc_type = "TT:ATCCOM.ATC_NAME AIRBUS.0.text"
atc_model = "TT:ATCCOM.AC_MODEL A319.0.text"
icao_type_designator = "A319"
icao_manufacturer = "AIRBUS"
atc_type = "TT:ATCCOM.ATC_NAME BOEING.0.text"
atc_model = "TT:ATCCOM.AC_MODEL B773.1.text"
icao_type_designator = "B77W"
icao_manufacturer = "BOEING"
atc_type = "TT:ATCCOM.BLANK.0.text"
atc_model = "TT:ATCCOM.AC_MODEL E135.0.text"
icao_type_designator = "E75S"
icao_manufacturer = "EMBRAER"
atc_type = "TT:ATCCOM.AC_MODEL AT45.0.text"
atc_model = "TT:ATCCOM.AC_MODEL ATR72.0.text"
icao_type_designator = "AT75"
icao_manufacturer = "ATR"
