Trim Sounds

Recommended Posts

I've been spending several hours searching the web and calling some contacts but I have been unable to find and answer to a simple question... How does the 'trim in motion' sound in an Airbus.On most 'old' style cockpits you find the trim wheel that rotates and that makes the nice clicking sound. On some aircraft there never used to be a sound. But on an Airbus I know there is a digitally created sound. I just have no idea what it is like. In the past there have been many airbus cockpits that include trim sounds, but these are all incorrect (all based on a 727 recording).Anybody here able to help me?Mathijs KokLAGO

I'm really not an expert on this topic, but is there any need for manual trim during normal flight in a modern Airbus? This page (http://www.airbusdriver.net/airbus_fltlaws.htm) suggests that you need to trim only in direct law and mechanical backup mode. I'm not sure if any simulated Airbus supports these modes ...Let's hope some real Airbus addicts will enlighten us!VOlker :]

Hi MathijsThe trim wheel on the A319/320 series doesn't make a peep. The rate of movement on the wheel is Extremely slow and not like the 727/737 trim wheel that was actually connected to the stabilizer jackscrew. This one is simply what the manual yoke trim switches are on the Boeings and other A/C. No place for Trim Switches on a sidestick :-) The Airbus FBW system also adjusts the trim automatically based on Sidestick position, so if you keep applying back pressure it will trim nose up automatically to take out the pressure.Hope this helpsRegardsPaul GollnickTechnical Operations/Customer Operational SupportPrecision Manuals Development Group[www.precisionmanuals.com]
