I did a flight between VABB & VOHS & encountered couple of issues (sim version: FS2004):
1. At VABB, I was never asked to switch to tower frequency automatically as I approached holding point for runway 27. I had to manually switch over to tower to request takeoff clearance. Another issue I observed that TGS also stopped giving instructions half way through (the gauge was stuck in one direction as well).
2. I was assigned runway 27L for landing at VOHS. I was following a STAR - NAMSA6 arrival (but with STAR option unchecked as I needed vectors after last waypoint in STAR as per plates). I was asked to descend to 7000ft when I was at downwind & subsequently base (& turn to intercept ILS 27L). This is a very high altitude to maintain & I was unable to intercept the glidescope (though I did descend rapidly to still execute a landing).
3. After landing at VOHS, I had selected gate 55 as pre-assigned gate. Again TGS got stuck at some point and was not giving any guidance.
I am attaching the logs for the flight.
