If applicable, which aircraft is experiencing this issue:
Cap-4 Paulistinha

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
No 3rd-Party or Community Addons (default installation) / Yes

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every Time

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. In Control settings, determine which keyboard or controller button is assigned to TOGGLE PARKING BRAKES, e.g.:
    Microsoft Flight Simulator 2024 3_12_2025 8_08_28 PM
    Make sure that this assignment is unique to TOGGLE PARKING BRAKES.
  2. In free flight, start a flight cold-n-dark in the Cap-4 Paulistinha at any airport during the day.
  3. Enter the aircraft (no need to do the walk-around).
  4. Look down at the right-hand side of the pilot seat and either use the mouse of assigned control to set the parking brake to ON.
    Expected behavior: Parking brake remains on until toggled off again.
    Actual behavior: Parking brake auto-toggles off after ~ 1 seconds.

Note: I have confirmed that this occurs with two different keyboard assignments that are unique (i.e. have no other mappings), so this is issue is not caused another controller binding interfering with the behavior of TOGGLE PARKING BRAKES, which works as expected in numerous other aircraft.

• Yes

Provide extra information to complete the original description of the issue:
• Also tried using Parking Brake ON but had the same issue

WORKAROUND: Assigning Parking Brake SET to a toggle switch does work. The parking brake releases when the toggle switch is released.

I’ve actually used the detent below minimum throttle on the Velocity One Flight Stick. With the throttle in the detent the parking brake is held on. As soon as I advance the throttle it releases the parking brake.

• why all the questions about system settings?
the binding on my flight stick that i assigned to parking
brake works on all other aircraft but the new Cap 4. Seams
to be an issue with this aircraft programing and not related to
anything in MSFS Bindings or hardware.
