I will be installing Garmin G3X displays together with a host of Garmin items.
Can the Garmin G3X system be programmed to have verbal and visual alerts.

Yeah having flown professionally in aircraft with aural alerting systems for a long time (20 years), I found that puzzling too. Part of the reason things like GPWS aural alerts were invented was due to the number of aircraft permanently parked on the sides of mountains. Similar principle for stall alerts, TCAS, etc.?...I think they are distracting to the pojnt of causing a safety issue...?
Really?
Is there anyway to suppress or knowledge an alert and keep it from going off?
We provide the option of enabling/disabling traffic or terrain alerts from the Traffic and Terrain pages, respectively. While on either one of these pages, press the Menu button and you will see this option.
If you have terrain alerts enabled, and expect to hear audible warnings, we want to make sure that warning is not muted. If you do not want to hear the terrain warnings, all you would need to do is disable them from the terrain page.
If you are experiencing nuisance terrain alerting, we do provide the ability to customize when alerts are generated by the system. There are a few different settings you can change to do this:
? Caution Elevation?The G3X Touch will provide an alert if the terrain or obstacle is within the default Caution Elevation or user-defined Caution Elevation.
? Look Ahead Time?Determines the maximum time when an alert annunciation occurs. For example, if 120 seconds is selected, the G3X Touch provides an alert up to 120 seconds before you reach the terrain or obstacle.
? Alert Sensitivity?The three Alert Sensitivity settings (Terrain, Obstacles, and Descent Rate) determine what level of alerts are annunciated. The G3X Touch defaults to ?High? sensitivity, which annunciates all red and yellow alerts at the time set in Look Ahead Time. ?Medium? sensitivity annunciates all of the red and the highest priority of yellow alerts. ?Low? only annunciates red alerts. ?Off? disables the alert.
See this post for a bit of insight into the practical modification of these settings: http://www.vansairforce.com/community/showpost.php?p=1243489&postcount=8
? Accessing the terrain settings:
1) From the Terrain Page, press the MENU Key.
2) Touch Caution Elevation and touch 500ft Below, 750ft Below, or 1000ft
Below.
Or:
Touch Look Ahead Time and touch 60 Seconds, 90 Seconds, or 120 Seconds.
Or:
Touch Alert Sensitivity... > Terrain, Obstacles, or Descent Rate > Off, Low,
Medium, or High.
Or:
Touch Alerts to toggle between Enabled and Inhibited.
Or:
Touch Profile View to toggle on and off.

Thank you Justin. While this is very beneficial, I am wondering about any other alerts. Lets say that I am getting an alert for my oil temp that is a bit high and got my attention or the CO detector is alerting me. Can I accept/acknowledge it so it is not blinking at me any more?

So we should do away with:
Traffic, traffic
Pull up
Wind shear
Obstacle
Fire bells
Airspeed low
Etc?
In the Flying Tiger Line accident on approach to Kuala Lumpur, the crew did not react to GPWS alerts because they had a false mental model of their position while in IMC. They subsequently crashed into the terrain which the GPWS was telling them they were about to crash into.
The accident seemed to be a litany of poor procedures, poor radio phraseology, very poor crew management, and poor SA. Nuisance alerts were not a factor. The alerts they had were genuine and they duly ignored them, so I don?t really understand how the accident could be attributed to the mere presence of a terrain alerting system.
If you?re commonly flying at low altitude in VMC and get consequent nuisance alerting, you may want to turn terrain alerting off or have it setup with tighter proximity margins.
In an airliner, the terrain warning is NEVER turned off...
So for the sake of clarity, the terrain warning system is NEVER turned off for normal operations...

We're not talking about airliners. We're talking about sport EAB airplanes under Part 91. Aside from the RVs I own an Aviat Husky and am partners in an new turbine SEAT fire bomber. You want to go insane hook up terrain warnings to unswitched audio. Same goes for traffic when flying formation. I see no sense in STC instructions assuming everybody is an airliner with full time aural anunciators. I say the alerting systems should follow a customized sterile cockpit rule based on the installed airplanes' mission profile. Every fire bomber I know either doesn't hook up the unswitched audio alerting or hooks it up to a switched selector on the audio panel, like com3 or ADF. STC instructions be danged.
There is an old joke where a twin landed gear up and somebody asked the seasoned pilot how it could have happened, and he responded that he was all dialed on the approach until all those flashing lights and bells made him loose his concentration. Not all pilots have the same makeup and some are more visual, some more auditory and others might need a poke in the ribs.
If someone flies their RV extensively in IMC under IFR rules then it would be advisable to have alerts available, but still at the option of the pilot. The other 90% of RV flying is VFR where unswitched audio alerts are fatiguing and can even freak out passengers on the intercom.

Optional remote TERRAIN MUTE Button/Switch to quickly mute nuisance Terrain Warnings when flying VMC in mountainous area or approach surrounded by terrain in VMC.
Mute sound warning only, visual cues shall remain visible on map and synth vision.
Normally, (if installed) this switch should be guarded.
This has been a good and timely discussion as I have an independent low fuel warning system from Aircraft Extras in my RV8 that sometimes is very distracting. When I installed it I calibrated it with IFR operations in mind to alert at approximately 30 minutes fuel remaining in each tank (~4 gallons). However, I have found that due to fuel sloshing uncovering the optical sensor during turbulence or any maneuvering, the alarm will alert with as much as 8-10 gallons remaining in either tank. Trying to continually acknowledge and silence the alarm particularly during formation flying is a real pain and potentially dangerous since the acknowledge/reset button is panel mounted. What is most distracting isn't the alert lights but rather the audio alarm. I like Keith's solution (post #3) and intend to utilize an unused switch on my Infinity stick to silence all aural alarms.
I too have Garmin's G3x system in my plane and while its alert settings and sensitivity can be adjusted, having to go into a menu, find what you want and then only able to either leave the system enabled or completely inhibited while flying in my opinion is not the best solution. What's needed is a simple one touch method for simply acknowledging and silencing the alert without completely turning off the system. Voice activation would be even better.

Hello,
Just a reminder that there are already very quick and efficient ways to disable traffic and/or terrain alerts on a G3X Touch system if that is something you need to do on a particular flight.
Select the terrain or traffic page, press the Menu button, and enable/disable alerts for that type.
This is all explained in the Pilot Guide.
One the next power cycle, these alerts are automatically re-enabled at power-up.
Thanks,
Steve
