I just looked at the Aerocache of the day for April 15 (Kalohi-Pallolo Channels) and think there is a problem with the instructions. It states to fly the intersection of Lanai VOR on the 210 radial, the Maui VOR on the 88 radial, and the Molokai VOR 285 radial. VOR radials extend away from VOR on the magnetic course indicted by the number. Therefore, the stated radials do not intersect.

 

If the reciprocal of the given VOR radials is used, they do intersect. This would make the instruction state Lanai VOR 030 radial, Maui VOR on the 268 radial, and the Molokai VOR on the 105 radial.

 

Just a thought. I haven't finished flying it yet, but I think I have a better chance of finding the point with the adjusted numbers.

 

Happy flying,

GW

Hi GW:

It can also be seen the other way around.

 

Think of it this way: If you were “standing” at the aerocache location, the given VOR radials are correct.

From that point you are at the intersection of inbound radials to MKK 285, LNY 210 and OGG 88

 

For those interested, see this sectional: http://skyvector.com...chart=38&zoom=8

I didn't worry about the radials or intersection. I had a good idea of the general location, and just flew a box search pattern until the cache showed up. Didn't take too long.

Hi Ramon,

 

Just to keep the argument alive... :Big Grin:

 

Radials are never "inbound"...

 

If one would say, "From that point you are at the intersection of inbound bearings to MKK 285, LNY 210 and OGG 88" that would be correct terminology.

 

A quick look that the LNY 210 and OGG 88 never intersect was my tip "they got their bearings crossed" or something like that. :P

 

Fwiw,

Rob

I stand corrected Rob. The correct word should be bearings, not radials. :hi:

Yep, this is the correct way they should have said it. The first thing I did was look on my Hawaii sectional and see that the given radials all point away from each other and never intersect. The second thing I did was assume they had given the reciprocal radials and fly to that point. :Thinking:

Radials are named for the degree heading from the VOR, never towards it. The 180 radial extends from the VOR; it is not also the 360 radial. And so on. I still have my old ProPilot Handbook where I checked :Peace: , best compilation of the AIM that I have ever seen for flight sims.

 

Best regards.

Unfortunately, "bearing" doesn't indicate that you're supposed to use the VOR, while "radial" does. It'll get people doing some outside research.

 

What they did give is the settings to put on the instruments if you fly from the indicated airport. Probably a lot less confusing, unless you're already an expert, in which case you aren't confused anyway.

Was just going to post about this because I was wondering how those 3 radials could ever intersect (without taking the reciprocals obviously!) Should be able to find it now!

I stand corrected Rob. The correct word should be bearings, not radials. :hi:

 

thanks for this infomation. having instructions for this aerocache forces me to learn more about flying. So that I can fully understand, a bearing is heading away from a VOR and a radial is heading to a VOR?

Radials "radiate" outward from the VOR. So, the 090 radial (due east) is a straight line running east from the VOR.

 

 

Jeroen used this image in his big VOR thread. The VOR station is at the center. If you're located due east of the VOR, you are "on" the 090 radial.

 

If you want to fly toward the VOR, you need to head west. The VOR station is located on a bearing of 270° from you.

a bearing is heading away from a VOR and a radial is heading to a VOR?

 

Reverse that... For VOR Think:

 

Bearing - To (a station)

 

Radial - From (a station... bearing from = a radial... radial always from)

 

:hi:

 

I need a :hand_salute: smiley :hi:

Screw all that "bearings" and "radials" stuff... someone should have told me it wasn't down on the water... lol
