Greetings all,
I am also experiencing the "NO GS" issue with Air Manager G5's with the 750GTNXi when using an ILS approach (using NAV1).
The old style VOR head (round dial) glide slope does work with the 750GTNXi when in VLOC and NAV 1 is engaged.
When looking at the in-sim aircraft panel, the aircraft HSI is picking up the glide slope, so we know the ILS is working.
When doing an RNAV GPS approach with the TDS 750GTNXi, the Air Manager G5 glideslope does work.
As a test, I removed the TDS GTNXi plugin, and used the default Laminar Research GTN 530 GPS navigator (I am using the Laminar Research Baron B58 with the REP package) that came with the aircraft and the ILS was showing on the Air Manager G5's.
Here's a link to the Air Manager datarefs
https://www.siminnovations.com/xplane/dataref/
I think someone above was asking for the "no flag" GS dataref, which I found in the link above:
sim/cockpit2/radios/actuators/nav_receiver_glideslope_off (Nav receiver N should not tune paired UHF frequency to pick up a glideslope. If this is on, the receiver will only pick up localizers, but not glideslopes)
sim/cockpit2/radios/indicators/nav1_flag_glideslope (Glide slope flag, nav1 - EFIS style flag that shows when glideslope is expected, but not received)
sim/cockpit2/radios/indicators/hsi_flag_glideslope_pilot (Glide slope flag, pilot side HSI - EFIS style flag that shows when glideslope is expected, but not received)
sim/cockpit2/radios/indicators/hsi_flag_glideslope_copilot (Glide slope flag, copilot side HSI - EFIS style flag that shows when glideslope is expected, but not received)
sim/cockpit2/radios/indicators/hsi_flag_glideslope_pilot_mech (Glide slope flag, pilot side HSI - mechanical instrument flag that shows whenever no glideslope signal is received)
sim/cockpit2/radios/indicators/hsi_flag_glideslope_copilot_mech (Glide slope flag, copilot side HSI - mechanical instrument flag that shows whenever no glideslope signal is received)
X-Plane12 12.3 beta
TDS 750 1.0.0.6
750 Trainer 3.10.3.0
Air Manager 5.0.7
If I can help with troubleshooting I'd be happy to help! The TDS is a fantastic product and I'm enjoying using it.
Best,
