Brief description of the issue:

This is a tricky bug to replicate. It requires a GA IFR flight scheduled for take off at an uncontrolled airport whist you observe it.

What occurs is the IFR flight will request take off clearance from the “tower”, which doesn’t exist. Since it doesn’t receive clearance, it sits indefinitely waiting for the clearance that never comes.

What I unable to determine (I don’t know how ATC is coded) is if this bug is just a general ATC bug/anomaly, or if it is somehow tied to the incorrect model matching that often occurs with GA at smaller airfields.

In this screenshot the aircraft, in reality, is a Cessna T210 – a piston single – yet is being model matched as a small twin-jet airliner.

I’m wondering if, when the sim identifies an aircraft as an airliner, it is causing the confusion with a tower clearance request. That or it has nothing whatsoever to do with it and this is just a bug with ATC that happens occasionally.

I have experienced this several times now (at this specific airport – KPRB) and was finally in a position to capture a screenshot of the behavior. I’ve seen this with & without mods installed.

This is the flight:
N210WZ Flight Tracking and History 07-Nov-2023 (KPRB-KSDM) - FlightAware

Provide Screenshot(s)/video(s) of the issue encountered:

Detailed steps to reproduce the issue encountered:

Preview FlightAware (or equivalent) for a pending scheduled IFR GA departure from KPRB. Load C&D and tune COM to CTAF and monitor. Note aircraft requesting takeoff clearance.

PC specs and/or peripheral set up if relevant:

N/A

It just happened again. You can see the ATC window indicating the pilot indicating they are “ready for departure…”. Then, as I was typing this another aircraft did the same thing.

Here is another example. It looks like the issue is not tied to model matching, because here is a Cessna both in type and actual model, yet it has the same issue re: IFR take-off clearance.
