Help with two issues in my cockpit

[fsaviator]

Good morning

Two issues some of you may be able to help on.  I'm using Prosim737 v3.36 with P3D v4

First - I have one of the first Revolution Simproducts motorized TQs produced - controlled via SIOC in Prosim737.  All the functions seem to work for the most part.  My MCP is the CPFlight 737NG V3 Ethernet version.  I am aware that officially, Prosim-AR ceased to support the RS Motorized TQs somewhere around v 2.1, and that is why I continue to use a SIOC instance to control the TQ.

On take-off using TOGA, with A/T armed, I spool up to 40% and press TOGA.  Plane accelerates, and then throttles cut-out forcing me to increase power to Take-off thrust manually.  Once I'm airborne everything seems to work fairly well in regards to moving levers, speed brakes and spoilers etc.

On approach and just prior to touchdown, when I activate A/T disengage on the TQ, the A/T switch auto disengages on the MCP, but the TQ thrust lever motors do not disengage.

Second - due to limited AXIS on my Leo Bodnar card, I have mapped the Tiller to the CPFlight MCP Tiller connection.  It calibrates fine in Prosim737.  In sim however it doesn't respond forcing me to use my rudders to steer during taxi.

Thanks!

Hi Warren, Good to see you've got something flying.

On take-off using TOGA, with A/T armed, I spool up to 40% and press TOGA.  Plane accelerates, and then throttles cut-out forcing me to increase power to Take-off thrust manually.  Once I'm airborne everything seems to work fairly well in regards to moving levers, speed brakes and spoilers etc.

A couple of questions regarding this, do the throttle handles move up to the correct N1 value after you press TOGA?
Second, does it happen at 80 knots?

In Boeing's, once you press the TO button, the handles move to their calculated N1 value, then once the plane reaches 80 knots, it enters 'Throttle Hold' mode which disconnects the servo clutches from the throttle handles. This prevents the auto system from doing something dumb during a critical phase, and if an RTO is needed, the crew is not fighting the auto throttle while rejecting.

In this case, it is possible that your handles are not reaching the set N1 point before 80KTS, then when it enters throttle hold, the sim is seeing the position of the handles and reducing thrust to that point.
