Hello fellow pilot,
The scenario you've described appears to be a common issue that many virtual aviators encounter, particularly when approaching the crucial moments of a flight. This could potentially be attributed to a couple of factors.
First, the beeping sound is commonly associated with an aircraft warning system, the Master Caution or Master Warning (system-wide alerts for major or minor issues respectively). This sound is triggered when there's an issue with your aircraft's systems, like engine failure, electrical problems, or, in your case, potentially an autopilot issue.
To further elucidate, the autopilot may have failed to capture the glideslope, resulting in the aircraft maintaining the last given altitude. This usually happens when the aircraft is not appropriately aligned with the runway or is at the wrong altitude when attempting to intercept the glideslope.
In terms of the altitude, typically you should be around 2000-3000ft above ground level (AGL) at the initial approach fix (IAF). If the altitude is incorrect, the glideslope may not be intercepted properly, resulting in your aircraft failing to descend along it. This is one potential cause of the incessant beeping - it could be alerting you to the fact that the aircraft is not following the approach path as it should.
Secondly, the beeping could also be attributed to the overspeed warning. Although the specifics of this warning vary between different aircraft, generally, it triggers when the aircraft exceeds a safe or designated speed. With your speed at 300kts at FL320, it's possible that the aircraft was exceeding its maximum operating speed upon descent, thus causing the warning.
Now, let's tackle these issues one by one.
- To avoid the issue with the autopilot, ensure that the aircraft is correctly positioned for the approach, both laterally and vertically. This means you should be lined up with the runway's extended centerline and at the right altitude for the approach phase. Also, ensure that the localizer frequency is set correctly, and the navigation source is set to NAV and not GPS, unless you are flying an RNAV approach.
- To ensure you don't get an overspeed warning, try reducing your speed to below 250 knots when you're below 10,000 feet. This is not only a rule in real-world aviation, but it also helps in better managing the descent and approach phase of the flight.
Remember, flying is a skill that requires continuous learning. I'm glad to see you seeking help here and expanding your knowledge. With practice and patience, you'll have a better handle on these situations in the future.
Do note that while my advice pertains to Microsoft Flight Simulator 2004, the principles of approach and descent, aircraft warning systems, and autopilot usage remain generally the same across all platforms, including the newer Microsoft Flight Simulator (2020 release) and X-Plane 12.
Happy landings,
First Officer
