GTN650 local time question

rockit · #1 08-31-2019, 09:14 AM

for folks that fly behind a GTN650 I had a question.
Under system there is an option to set a local time offset. When I am flying cross country and will cross time zones, i have to go in the manually to change the local time offset so it will display local time.
Is there a setting which will allow the GTN650 to automatically change to local time when the aircraft enters a new time zone?
I cannot seem to find it in the manual.
Thanks.

No. I wish there was one. Same issue with Dynon. Makes you wonder why they haven't implemented that feature

My G3X does the time zone change automatically but not the GTN650 right next to it

Jeez guys, what do you expect in a state of the art $10,000.00 whizbang box made by the leading avionics manufacturer? An automatic clock!

This thread reminded me of the problem the F-22 Raptors had the first time they tried to deploy across the International Date Line, flying from Hickam AFB in Hawaii to Kadena AFB, Japan.

Maj. Gen. Don Sheppard (ret.): “…At the international date line, whoops, all systems dumped and when I say all systems, I mean all systems, their navigation, part of their communications, their fuel systems. They were — they could have been in real trouble. They were with their tankers. The tankers – they tried to reset their systems, couldn’t get them reset. The tankers brought them back to Hawaii. This could have been real serious. It certainly could have been real serious if the weather had been bad. It turned out OK. It was fixed in 48 hours. It was a computer glitch in the millions of lines of code, somebody made an error in a couple lines of the code and everything goes."
