### Time To Fly Through Time Zones?

Example:

Suppose I fly from Los Angeles to New York at a Ground Speed of 550 mph. How much time would it take to fly each time zone? In other words for example, how much time would it take to fly from a Pacific Time Zone to a Mountain Time Zone at a ground speed of 550 mph? Im talking in terms of EACH single time zone. Not from Pacific to Eastern....

Rather than give you the answer, this is how you could determine it....

Get a map, draw a line between LA and NYC. Measure the distance between time zone changes or boundaries.
The distance on the map in miles of the line from LA to the Pacific/Mountain Time Zone line, divided by 550 would be the Pacific TZ travel time in hours.
Repeat above for Mountain TZ.
Repeat above for Central TZ.
Repeat above for Eastern TZ.

Or head up to 89o 58' north and you can do most of them in two minutes.

Last I heard there are 29 time zones, of which, 24 are based on longitude. The 360o of longitude, divided by 24 hours in a day gives you the basic time zone of 15o. At the equator that would be 900 nautical miles. At 45o north or south it would be roughly 636 nautical miles across a time zone.

Over populated areas the question gets confused because the time zones don't follow the meridians of longitude, but tend to follow state lines with doglegs to include or exclude certain locales. Then there are places like Arizona which does not observe daylight savings time.

After countless coast-to-coast flights I can tell you that the aircraft clock is reading in GMT and each crewmember has their own watch-setting ritual. I always stayed on my domicile time and converted locally.

Way to go CitationJet!! Make him think a bit....

The question is not very well defined, a lot of variables are left out. Therefore there is no one right answer to the question.....

I agree SATL. That's why I didn't give an answer, everyone would criticize it. What I provided him was one way to determine an answer, given his criteria and assumptions. My method eliminates the discussion of latitude/longitude and state boundaries regarding time zones. Another thing is, the plane would not be flying perpendicular to the time zone boundaries, it would be flying in a northeasterly direction, not directly east.

### RE: Time To Fly Through Time Zones?

Sorry, I am going to torpedo your question.... Zero Minutes! (Or infinity, depending on how you look at it.) When you're flying, especially across time zones, your aircraft should be operating in zulu, gmt, utc, whatever you wanna call it. Its one and only one time zone from the moment you step into the aircraft to the moment you step on terra firma, so you basically warp from pacific time to eastern time.
