Can you fly a direct GPS route on international flights?

For example, can you legally fly a direct gps route from Guadeloupe to Opa Locka, FL? Or would you have to stick to airways?

What are all the current reasons why our General Aviation system still uses airways?


If you are VFR (Visual flight rules,) you can fly any route you choose as long as you dont get into restricted airspace along the coast. You have procedures to get into US airspace, but yes you could go "GPS direct. Flying on the airways might be assigned to pilots filing and flying IFR (INSTRUMENT flight rules) where thier clearance will assign them route to fly. some times you CAN get GPS direct if you request it.

I dont hink you could land at OpaLocka though, you are required to first land at a designated port of entry for a customs "inspection" when coming in from out side of US airspace.

edit: I stand corrected and educated, I learned something today!Thanks for the info.

Short answer is, usually not.

Miami's radar coverage extends to about Hispaniola, where you're usually picked up by Santo Domingo and then San Juan. In a radar environment, "direct to's" are common. However, over the Caribbean Sea there is no radar coverage . Therefore to ensure adequate traffic separation, aircraft stick to the airways and periodically report their position, altitude, mach number and estimates for the next fix.

It is common to be in and out of radar coverage through much of Central and South America. Hopefully satellite based radar will eventually allow us to fly direct anywhere in the world.

EDIT: Cherokee, I clear customs at Opa Locka routinely

Please, dont take any advice from ANYONE online telling you what airplane routes to fly.

99.9999% of people are not pilots, and never have and never will fly a plane in their life.

ask an airtraffic controller instead, or another experience pilots.

From what i hear, air traffic controllers are the one's that give clearance to which routes can be flown.

and if you do fly a route, that another faster plane is flying, you will end up getting too close, and could possibly cause an accident, like what happened to me earlier this year on a flight from boston to atlanta.

it wasn't on the news, but a plane flew directly beneath us, no more than 300 yards away. (it sounds like a good distance, but when you see another 747, cross paths beneath you , its pretty scary.

When you have thousand of plane at the same time and they are all going in random direction, it is impossible to keep them from crashing into each other.

But if planes follow general "corrodors" then it is much easier for air traffic to keep them apart (and organized).

But I used to fly small private plane and were were mostly free to fly direct line of sight paths (unless there were restricted air space).

Small planes are too slow to go miles off course and make it worth flying.

Good Luck.

I think you have an assigned flight path. It uses different airways.

In short, no you cannot

Can you recommend an inexpensive GPS system that could be used for both geocaching and navigation?

Please note if any additional upgrades have to be bought to add navigation. I could most likely get by with little detail at the city level. I would just like to know how far it is between towns when driving, etc.

Also would like to try a little geocaching. A GPS unit for me is a luxury, so I don't want to blow a lot of money on it.

Thank you.


Unfortunately mapping and inexpensive seem to be mutually exclusive. The Garmin eTrex Legend might fill the bill, but the base map on this (and most GPS units) does not include any city detail. For the eTrex, you would have to purchase City Navigator, which actually covers all roads, not just the cities, but it costs almost as much as the GPS. List prices from Garmin are 139 for City Navigator, and 160 for the Legend. Street prices will be somewhat lower. One of my pet peeves is that all the major GPS manufacturers have proprietary mapping software, and you can't mix and match.

While you can get by with the Legend, there are two things that would disqualify it for my personal use: No electronic compass and only 8 megs of room to add extra maps. One "wild card" GPS is the unit now offered by DeLorme, the PN-20. Can't speak from experience, but it sounds interesting, and may be worth investigating. It's not really cheap, but perhaps the bundle with mapping software could be attractive.

Bottom line is that cheap probably isn't the best way to go.

Hey, try this new site www.gpscosmos.com I just learned about. They had a lot of units and accessories. I believe they may have mentioned geocaching too. LOT of fun.

It really depends on which application you want to use it more for. Based on your needs, if you just want distances between points, and don't care where the nearest restaurant or gas station or ATM is, you're probably fine with a basic handheld GPS. The Garmin eTrex Handheld lets you save some of your own "waypoints" as you define them, and you can get one for $60. It is, admittedly, difficult to use in a car and eats batteries rather quickly, but for what you said you wanted, it might be perfect...and it's about the cheapest one you'll probably find, unless you can find one on sale used.
