I’m working on the RPN scripts for the Aerosoft CRJ.
The scripts to turn FCP knobs work well, for example:
ASCRJ_FCP_HDG_dec
(L:ASCRJ_FCP_HDG_SEL,·Number)·10·-·dnor·(>L:ASCRJ_FCP_HDG_SEL,·Number)·(L:ASCRJ_FCP_HDG_CHANGE,·Number)·–·(>L:ASCRJ_FCP_HDG_CHANGE,·Number)
But the similar script for tuning the NAV radios on the RTU, doesn’t work:
ASCRJ_RTU1_KNOB_OUTER_dec
(L:ASCRJ_RTU1_KNOB_OUTER,·Number)·10·-·dnor·(>L:ASCRJ_RTU1_KNOB_OUTER)·(ASCRJ_RTU1_KNOB_OUTER_CHANGE,·Number)·–·(>L:ASCRJ_RTU1_KNOB_OUTER_CHANGE)
When I test it in AAO the values are not changing in response to pressing Test button, the Knob in the sim is not turning:
However, when I turn the knob in the sim, I can see the values changing (see the result after 2 decrease clicks in the sim below), so the LVARs seem to the correct. For some reason the knobs are not reacting to the script.
