Hi Waldo,1. You could use MS sound recorder to reduce the volume of the alarm sound file. Sound recorder is located via Start | Programs | Accessories | EntertainmentThe file will be under the FS sounds directory in a PMDG747 subfolder.***Make sure you save a backup of this file! Any problems borne out of modifications isn't covered by support.***2. Assuming you are using VNAV to manage your climb, cruise altitude and descent, then you will often find the aircraft will creep ahead of the commanded speed. Either use the speedbrakes intermittently to curb the speed or better still you can click on the centre of the MCP speed knob to enter Speed Intervention mode. Then dial up the desired airspeed and the aircraft will slow to it. Possibly the best feature of the autopilot to learn about.3. To turn on TCAS go to the transponder on the center pedestal. There is a small rotating switch just on the captains side of the 4-digit readout, rotate it to the right to the 'TA/RA' setting. Bingo, TCAS.Hope this helps, make sure you are checking in the manual too, it's a good read and will enhance your enjoyment of the aircraft.CheersMark

for 1. - Did you try using the volume slider in the PMDG options menu?

EagleSoft Cirrus options panel? I've never seen an options panel with it. What are you talking about?

ES Cirrus Options panel

Ok, can you give me a hint where this slider is?Never mind, I found the options under PMDG on the Menu bar.Thanks all for help.

I just purchased this jet two days ago, flew it a few times, and I must say it's a real joy to fly. PMDG has done another fine job!Questions1. PMDG, do you think that when you make another release for the QoS that you could put in an option to control the volume of the alarms?(they are way too loud for my ears and my cat is complaining too)(for example see the Eaglesoft Cirrus options panel; it's nice)2. What is the best procedure to slow this aircraft down?(I am having trouble slowing down when arriving at the destination)(my face is spread all the way down the runway at EGLL, lolol)3. There is a yellow colored display stating "TCAS off". How do you turn it on?
