Yeah, one of my kids is an ATP and current airline pilot. The guys both usually bring their own GPS's believe it or not, set them up in the cockpit for auxiliary b/u use, but not for anything serious. His airline won't yet buy into any GPS instrumentation or avionics, on their aircraft.
Yeah, they just use it for overall ETA, etc., to compare with what the company guys are telling them on their radio. They do a lot of ETOPS, so not only high but long.
What you do, boy, that is some flying. Son's bro-in-law was laid off from his job for about 18 months and worked EMS is SoCal, mostly east of the Sierras, Hemet, Palm Desert, etc. Whole diff. world (of course, he was fixed wing.) Off the subject, but it's been a tough year, year and a half, for the helo EMS.
I looked in Homeport and the island is missing - it only shows "breakers". If you look closely, you'll see that the charts at the entrance of the inlet are 1:60,000 but it changes to 1:300,000 just before the island. Here's the chart info:
Chart Number: Bhbch03
Chart Name: The Little Bahama Bank
Scale: 1:300000
IALA Region: B (Red to Starboard)

Soundings Displayed in: Feet
Soundings Stored in: Meters
Projection:

WGS-84 Lat/Lon Delta: S0 00.000 W0 00.000
The Island has been there since the begining of tme. It has a beach and is coral rock and bush and is a significant size. I wonder if there is any way to get Garmin to add it to the charts and update the chartplotters.
yes I have paper chart and none of you would be able to use at that time at that place and that I make 3000% sure
If it's that complicated an area, how would you expect companies like Garming to have it right?

No, it is a matter of an Ocean Inlet which moves sand on a daily basis. If you not there everyday, you have no way of knowing where to be. The new channel was marked, I followed the bouys incorrectly. If I had read the notice to mariners put out previous to my trip, I would have seen the bouys were moved an extreme amount, and I would not have followed what I thought was the route....

And HOW would they know, if was not accurrate? Again, 1st they don't MAKE the data, and 2nd, they don't go to each and every spot to check the accuracy of the data they have been give. It's just not posible. The mistake being made here is, this is NOT an exact science, AND, we are NOT supposed to be relying on our chartplotters to navigate tight waters. That's the 1st thng that pops up on the plotter when you boot it, "DO NOT RELY ON THIS DATA...."

Cause that is what the government gave them.
Well bird-for once I agree--(raymarine guy)some of us do buy charts and know where we have to go--40 limit-you should too-as bird said-here is the screen you should have or close to upon start-up--ONLY AS A NAV. AID.
Birdman, could you for once leave your God Garmin aside and have a proper analyze?

It is not a complicated area, it is that to use a paper chart is impossible because of the accuracy you need, because you do not have the time to draw lines on a chart.

This is exactly as I wrote a problem of update (accuracy linked by time changes).

1. They do BUY the maps. Not necessarily from the government. Do they buy the right ones? Do they allocate the right budget to select the right updated maps?
2. Pop up, agreed. But easy from them. They however recalled charts after several accident of this type occured

You do not or do not want to understand. Do you believe they based on 2 maps? If yes, are they not able to simply superpose them and identify all differences? .
Edit: just checked, not a single map from the Government. The main map they used for that area is the paper one I have, and there are copyrights ($$$).
The copyrights, are from the PRINT company, who ALSO got the data from the Governement.
Garmin? This had nothing to do with "garmin". You are the one blaming Garmin, what I'm trying to educate you on is, it is the same for ALL companies, they all get the same data. The only difference is how they format it, and how they digitize it, Raster or Vector... But when they get data that is wrong, that is what they pass along to you. Remember, the world is a big place, and it constantly changes. I'm actually amazed we have all this data!!!

Hell, if I blindly followed my GPS chart plotter I would run into several buoys!
It shows them on the opposite side of me!
Not including numerous day markers that I had to add as a waypoint.
Know your area, waypoint what isn't on the plotter, hopefully have radar, read the Notices.
And don't go 40 mph at night or in limited visibility.
It just concerns me as we get a lot of Joe the Intercoastal Boater over here, especially on holiday weekends, that just follow the chart plotter day and night. With having no local knowledge, they could have a big problem one evening. We even have cases where boaters follow the plotters on a straight course from north Florida locations to Port Lucaya and run into the island around Freeport Harbour. They don't realize that the island runs North/South and then East/West.

I know on my plotter it just lays down a straight line between two points, even if a peninsula or even a city is in the way.
Ya think ppl are really following a course like that???
I can understand hitting an inland in that case.
Aren't these things supposed to lay a navigable course?
But of course, paper and a proper look out SHOULD be on board.

AFAIK, only the Garmins will do this (I'm sure others will correct me if I'm wrong) and in Garmin's case that is a feature which wasn't added untill about two-three years ago, and refined since them.
Check out that island closely, and see if there's a boat called the SS Minnow aground, and a little guy in a red shirt and white hat waving like crazy.....
