It’s just a tiny little extra that would add more realism to the simulator. When Ground issues you a taxi instruction, it sounds like “Callsign, taxi to runway XX, contact Tower when ready”. I propose to add frequency after, as it is usually done irl, e.g., “Callsign, taxi to runway XX, contact Tower on 118.3 when ready”. Even though it wouldn’t make a massive difference, it certainly would make it more realistic.
Nothing major, just a tiny add-on. A screenshot attached for reference.
Have a great day!
