Hello:

Yes, 100% Airbrake for TD works better.

Also, I was able to add one unit each of CIVA INS (CDU+MSU) gauges and enable INS Navigation for the CS-B52 (without an FSX GPS FPLN). I set the MODE SELECT knob to "TACAN" and the HDG SELECT switch to up/MAN before  flipping the CIVA INS/NAV switch to up/ON for FPLN activation. The plane nicely followed the LATLONG waypoints.

On the [VC] cockpit view, I had initially bit of problem getting the displays on the INS gauges but momentarily moving to the [2D]/Blank cockpit brought up the displays.

Thanks again for the tips and suggestions. Cheers!
