For example...
Say you are on the 270 radial at 10 DME from ABC VOR and want to figure out what heading to fly to go direct to a point on the 240 radial at 20 DME of ABC VOR....is there a quick way to figure this out?

Thanks
 
Man, that's 6 pages of back and forth locker room towel snapping. :D

To the OP: Turn the big knob to WPT group, then scroll the little knob to the User WPT page... Seriously though, I'm going to learn how to do the pencil method. It'll be fun.

The answer is pretty much in the first two pages......then it goes to hell. :)
 
still not sure what the pencil method is... that's a clusterf of athread

I got the method of twist to where you wanna go and head between header and needle, closer to needle if DME needs to go down closer to header if DME needs to go up
 
Mike, what would you recommend I search for to teach rated military aviators how to simply navigate to or from a vor using a HSI? Keep in mind you assume they were taught this in flight school so you really don't feel up to teaching the basics.

A follow up: The same military rated aviator does not know what a turn rate indicator is, where it is on the instrument panel, and what it is used for. This was discovered when being hammered about maintaining a standard rate turn the exasperated pilot admitted he didn't know what that was. The ensuing discussion led to the turn rate indicator and his lack of knowledge of what it was.

Has said aviator been flying VFR in OH-58s his whole career or something??
 
I did some searching but all I found was info on basic VOR navigation. The key was searching for fix to fix, I just didn't think of wording it that way until you mentioned it.

That's what I was meaning.....once you had a direction to go, there was good info out there, apart from the 7 page thread, 5 of which was drama! :D

Ian,
How does this student perform on a VOR or LOC/ILS approach? That is to ask: can he/she follow the HSI guidance on an approach?

First, an important technicality - this isn't a student - this is an instrument rated commercial pilot and rated aviator.

He can follow a final approach course... and I really wasn't looking for advice really - just venting about some of the people flight school graduates.
 
I tried doing fix to fix nav in the CRJ a few month back when our FMS was out. ATC gave us direct a fix (which was, on the chart, a DME and radial off a VOR). It's kind of a pain, but we hit the correct radial only 1DME from where we should have. I was actually pretty impressed.

Of course, we weren't really legal to take the clearance, but we were in the middle of nowhere, and it's not like the CRJ stays anywhere near the route centerline anyway when you are tracking straight down a radial.

I'm tracking. I forgot the "sarcasm" sign. I was (and am) amazed at the "end product" from formal flight training (including UCLA). Talking to an Inst. INSTRUCTOR from FSI; told me they did not teach STARs! Said, "We have a canned flight route; go here, go missed, go there, go missed, etc and then return". CRAZY......

The wind triangle side of a CR computer can easily and accurately find the answer. To get from the 270 at 10 to the 240 at 20, I come up with a magnetic track of 216. I got this number in about 15 seconds using a Jeppesen CR type circular slide rule. It is the same as using an RMI point to point, however it is much more accurate since you can plot lines on the numbers, instead of eyeballing them on an RMI.

First plot the 270/10 on the wind triangle, then plot the 240/20. Then rotate the until the destination plot is directly on top of the present location plot. An imaginary line drawn between these two points would be parralel to the vertical lines on the calculator. The number over the TC index is your magnetic track. Since VOR radials are magnetic, your calculated course will be magnetic. If you know the winds aloft, convert them to magnetic as well to get your wind correction angle.

Here is what it looks like on the CR computer. Since you used points so close together, I just used 270/30 and 240/60 for clearity in the picture. Since 10 is half of 20, and 30 is half of 60, you will get the same answer. I plotted your 270/10 and 240/20 also, so you can see the same result. Very fast and accurate. I am always within 2 or 3 degrees of my Rnav computed course when using this method.
