Garmin D2 PX Watch

Post by NDCDA62 »

I have just purchased the Garmin Delta D2/PX aviation watch, primarily for use in monitoring my Oxygen Level whilst in flight. The additional aviation features are indeed numerous and for those contemplating purchasing same, it is well worth downloading the User Manual which provides a more comprehensive overview than the sales leaflet.

I am delighted with this purchase which provides a further safeguard and back-up during flight.

Nigel, I just saw a discussion in one of my Facebook aviation groups that warned people that O2 sensors don't warm you about carbon monoxide poisoning. (Not as much of a factor in the twins, but I'm tossing it into the thread anyway.)

On the subject of carbon monoxide poisoning, this topic was discussed at length recently on the podcast listed below:

For those who haven't yet found the time to listen to the above mentioned podcast, I beg you to do so at your earliest opportunity.

As the survivor of this crash shares all kinds of valuable information. One of which is, when carbon monoxide is present in the cockpit, O2 sensors will actually indicate a higher than typical saturation levels (at a previously determined altitude for a given person*).

This is a result of the carbon monoxide molecule binding to the hemoglobin and is why having an appropriate CO2 detector in the cockpit can be lifesaving.

*It wasn't until after this Mooney pilot miraculously survived an almost certainly fatal crash, that he became aware of this misleading indication on his pulse oximeter.

I also highly recommend both episode 88 and 90 on carbon monoxide. Two big takeaways for me were:

1) Oximeters are fatally misleading when CO is present.

2) The number of sources of CO other than your air to air heater. Anticipating heating with a water to air heat exchanger I somewhat dismissed the dangers in 88 until I listened to what was reported when 600 owners started measuring CO and found many other sources.

Scott - Thanks for re-posting the carbon monoxide podcast done by Max Trescott and Dan Bass.

WOW - quite a story!! Dan Bass is VERY FORTUNATE to have survived the crash while unconcious from CO.

After listening to the podcast today, I went on Amazon to look for sensors. Prices for Sensorcon devices (linked from the podcast) were all full retail on Amazon. Dan mentioned he worked out a 20% discount with Sensorcon www.sensorcon.com for their portable devices and the info is posted on BeechTalk and the Mooney forums.

I found the code on BeechTalk - the code is aircraft2017 and it still works. So, if you're interested in getting a monitor after listening to the podcast (and I'm thinking most will be "interested") order directly from the manufacturer and save 20% plus free shipping!

I can see many other uses for this device - BeechTalk has a number of guys that found "leaks" in other places after buying one for their flying - house heaters, water heaters, cars......scary stuff.

Here's a link to some BeechTalk on the subject - https://www.beechtalk.com/forums/viewto ... n#p2278087 (not sure if you can see this without being registered??)

Here is Dan's post on BeechTalk once he heard they were talking about his accident- https://www.beechtalk.com/forums/viewto ... m&start=15

(Just in case you can't see it, I cut and pasted Dan's post below)

"Hey everyone, I've been a beechtalk lurker for years. I primarily follow the crash talk and now I'm reading about myself. Bizarre. Here is a repost of what I just posted on Mooney space.com. communication is slow right now due to my injuries, but I'll try to answer questions best I can.


I'm the pilot involved in this crash. I started writing up a summary of the events leading to to my accident but I'm having problems with my old laptop. My frostbite hands make using my phone and iPad difficult but I'll try to throw up some facts and field questions when I get a chance.

The FAA is still investigating, but I'm 99℅ sure this was caused from CO Poisoning. This was the 3rd flight of the day and in hindsight I had CO poison symptoms most of the day. The heater/defrost was run full-on the whole time. 5 hrs after the accident CO Poisoning occurred as a possibility to me, my levels were then tested 15-18X higher than normal. I didn't have CO detection in the plane. I was dumb and naive to think that I would "know" when I was effected. I was way wrong! The problem was that the CO degrades ones cognitive ability to the point where you can't connect the symptoms with the cause.

I passed out in the climb and woke up in a field. I am the luckiest man alive. Allot of things helped to have the great outcome I have been blessed with.

1- I was in a Mooney. The airplane gave it's life to save mine. I'm a huge believer in the "steel cage" and the full spar.

2- I was wearing a shoulder harness. I still busted up my face, I'm not sure how, but I don't think I would be here without it.

3- STec 30 auto pilot. I was flying with the heading bug when I passed out. The electric autopilot kept the wings level all the way down. The original PC system may have worked just as well, but the engine was windmilling from 12k to the ground. I don't know if there would have been enough vacuum.

4- it happened in the climb. I only have alt hold so it was tracking heading bug and trimmed for climb. As I was in the initial climb I still had in full power with full rich mixture. This resulted in a fuel burn in the 17-18.5 gal/hr. And only allowed the airplane to climb to around 12.5k. if it were leaned at all I would have went much higher, for allot longer. Being that I was oxygen starved and unconscious it probably would have been fatal.

5- ATC was awesome. Because of them search and rescue was underway before I crashed. After I woke up I had to get myself to help, once I did emergency responders were to me in a few min. My 121.5 ELT was working, but if I had a 406 I bet I would have been pulled from the airplane before I woke up.

6- luck, luck, luck, divine intervention, miracle, what ever you want to call it.

I'm banged up, but should recover 100℅. I came home from the hospital on my daughter's 3rd birthday. It doesn't get any better than that.

Cheers,

Dan"

Thanks to John for sharing the Sensorcon discount code with us! It worked for me as well tonight.

Soon after Max's CO2 podcast aired, all of these units (3 models) were sold out on amazon. Yet as a result of John's helpful research, the savings are just under $36, over amazon prime. I opted for the mid-range model, your savings may differ - depending upon your selection.

Skip Amazon and go to sensorcon.com. The code works there and you'll buy direct from the mfg.
