How long do IFR flight plans stay in PE system?

How long do filed IFR flight plans remain in the PE system before they are removed from clearance delivery's access?

As you know in the real world a filed IFR flight plan (at least in the US ATC system) can be opened by the pilot up to approximately two hours after the proposed departure time filed in the flight plan.

I filed a PE IFR flight plan but it may be 40-50 minutes before I actually start up the aircraft and obtain the clearance.

Peter,

As long as you remain connected to the system, the plan won't close. If you disconnect, the plan will remain accessible for up to 2 hours from the time it was either filed or last modified. If you reconnect during that 2 hour window, the plan will remain accessible indefinitely.

So, in that regard, it's a bit more generous than the real world.

Excellent info - thanks.
