I’ve actually never flown in a flight where a full reverse thrust is never deployed. But then again I live in SEA/APAC region, my country has short and narrow runways for the domestic only airports so different airline and airports regulations might be different from other places.
Of all the flights I’ve ever been on in the region, I always see the engine reversers open and the engine spools up really loud, only for a short time until it spools down and the reverses close. So I always assume they’re always on Full Reverse and never on Idle reverse thrust. I’ve actually never knew there is such a thing called reverse idle until I start flying the A320 in MSFS since I never experience anything like that in my flights.
As for @RomoRocket post, It depends on situation. For me, if it’s dry and I’m flying into a standard international airport. I always use Autobrake Low because I don’t want to overheat the brakes unnecessarily. Besides a deceleration rate that’s too fast is also uncomfortable to the passengers. Even on wet conditions, I still set it to Low if I’m still flying to big international airports with long runways.
Autobrake Medium is when I’m landing to medium length runway for regional airports that’s long enough to handle an A320 whether wet or dry.
On shorter runways (Like EGLC London City Airport, or VQPR Paro Airport), whether wet or dry I use Autobrake Medium, but after touchdown I apply maximum manual braking to override it because it’s really short and I need maximum stopping performance. I get brakes overheat warning sometimes, but it’s still better than overshooting the runway.
Either way, I apply Full reverse thrust regardless, because I’m using TCA Quadrant hardware that’s difficult to have Reverse Idle thrust since it doesn’t have the physical detent to place it to and it’s difficult for me to manually hold it in that Reverse Idle position due to a broken tensioning mechanism (ie. I can’t place the throttle in any position other than the detents without sliding off like it’s on ice). I imagine it’s even harder for Xbox controller to apply the same method too.
Autospoilers is mandatory for me too, as they’re not only used to slow down, but they’re crucial in “spoiling” the airflow to the wings and give it downforce instead of lift to keep the aircraft on the ground so that it doesn’t float anymore. So depending on the situation, I just adjust the autobrake but everything else is the same.
