Altitude, GS and Hold.
-
This aircraft is one of my favourite aircraft on Vatsim. Old school, amazing systems and feel. A true challenge to fly.
But, the BAE 146 is not capable of accurately capture and maintaining altitude. I have been testing this aircraft for the last few months. Biggest issue is altitude capture and precision. Aircraft constantly levels off 50-100 feet below selected and armed altitude.
I have only been testing this aircraft on Vatsim. Altitude, precision and accuracy is an issue. Aircraft not able to properly capture and maintain selected and armed altitude. Flight director too erratic. Should indicate slow, accurate and precise movements.
Hold, HSI is not operational after entering a hold. The HSI DME goes blank after entering a hold. HSI goes into "lost" mode. Turn radius is not realistic and accurate. Aircraft initiates turn wrong direction before turning correct direction etc. Huge improvements needed on the FMC side of the development.
GS (glide slope). 99% of the ILS approaches I have flown results in a minimum of one dot below GS. Aircraft not capable of accurately tracking GS on an ILS.
Last 1000 feet aircraft always goes below the GS. Minimum 1 dot. Landing short of runway every time without pilot intervention. Cat2. None. Not precise enough for cat 2.
Please tweak this aircraft to accuracy and precision in terms of navigation and automation.
It is an amazing aircraft. A true joy to manage and operate. Lots of us fly on Vatsim, precision and accuracy is vital and essential. -
I believe the BAe 146 was/is not RVSM-certified.
Based on some random 13 year old Pprune comment this behaviour is somewhat based on reality: "I think that the ASI is not corrected for compressibility and thus you have to level off approx 100ft below your planned FL and the aircraft will apparently "climb" the last bit as the speed increases."
It seems very erratic in the sim however and will sometimes be impossible to ever get it to assigned altitude even if you start manually "helping" it. I remember reading some tricks used for dealing with it in the real world on Pprune, but don't have links on hand.Regarding glide slope tracking I can only confirm your experience. Sometimes it will stay on it, but very often you have to disengage the AP. It can at times be equally bad at tracking the localizer, and just stay off to one side despite having miles to correct. I have been tempted to look into the files to see if there was a way to adjust this obvious problem with the controller, but at the moment my 146 spends most of its time in the hangar anyway.
Months ago the new FMC was right on the doorstep and they considered postponing the 2023-05-22 update to include it, but things have obviously not gone to plan.
