VOR Navigation question - Airliner - 28-01-2006
Okay, got a question here.
First, I just started up a new FsP airline flying Piper Cherokees in and out of the lakes region of New Hampshire (USA). One of the
primary routes will be linking KASH and KLCI. As I'm still working on getting my graphics card upgraded, I'm trying to avoid KMHT as
much as possible in my flightplan (I have Loney's scenery plus PAI traffic which slows me down going past it, using routing with the MHT
VOR).
I have a flight plan setup that keeps me well out of the MHT airspace to the west. I managed to fly it pretty well, with the aid of the gps but,
I want to be able to do it without, using just the OBS, etc. Okay, here's the plan, basically.
Depart KLCI
Follow the 352 radial from CON VOR (course 172) to KCON
Then, pick up the GDM VOR and follow it to the LURCH intersection or thereabouts
Turn to 139 and pickup KASH visually or ILS RWY 14 (or circle to RWY32)
Now, the question is how do I know when to make the turn to 139 degrees? I tried tuning OBS 2 to MHT VOR and aligning the radial to
intersect where the 139 heading into KASH would cross the GDM VOR I'm tracking but, the needle never moved. Perhaps, use the
DERRY NDB and turn when it's bearing equals the right intersection of my current course?
Sorry if this is too basic. I usually fly the big iron along jetways and don't have to deal with this too much.

Um, DUH! Rotate the OBS knob!
Re: VOR Navigation question - olseric - 28-01-2006
You're making this a lot more complicated than it needs to be.
I just looked at the sectional chart for that area, and if you are dead-set on using that routing, this would be my suggestion:
-Depart and fly direct to the CON VOR.
-After the CON VOR, fly direct to the GDM VOR. Should be about 43 DME. If you want to be technical and stay on the Victor Route, fly GDM
R042 inbound (set your course to 222).
-After CON VOR, fly direct to the MHT VOR. Should be about 36 DME. If you want to be technical and stay on the Victor Route, fly MHT
R253 inbound (set course to 73).
That Victor airway (V106) will pass just northwest of the airfield (looks to be about 1 mile).
Re: VOR Navigation question - Airliner - 28-01-2006
Um, no - YOU are making it more complicated.
The idea was to stay clear of MHT. I'm going into KASH. Anyway, I got it figured - just a stupid mistake when using the VOR.
I was thinking that calling for "CRS" with FsP would set the OBS knob. I didn't realize that that was different.
Actually, I'm flying the route mostly as you said anyway:
Depart KCLI and follow CON VOR, then switch to GDM VOR. The thing is when to turn to approach KASH. Now I know enough to set the
MHT VOR to the radial that intersects the airway that I'm already on on NAV2 - it's about 100 degrees TO. When the needle on NAV two
centers, I'll know it's time to turn to 139 which should line me up with RWY 14 at KASH.
Re: VOR Navigation question - olseric - 28-01-2006
If I looked at the sectional correctly, KASH lies under the Class Charlie of KMHT, so, I don't know how you could.

Okay, now I'm lost. Yes, KASH is as you say. So, does that mean I HAVE to fly via the MHT VOR?
I can understand being cleared through the airspace but, why can't I fly in from the west, right on the ILS RWY 14?
By the way, I just flew that route and my pax were pleased - we got in 1:23 minutes ahead of the planned 35 minutes.
Re: VOR Navigation question - olseric - 29-01-2006
Well, I'm just saying that it's within 10nm of the field, so I guess my theory of "staying away" and yours are a bit different, that's all.
The Class C airspace is meant mostly for VFR Traffic. It's meant to protect the IFR traffic operating at KMHT. In real life, a VFR flight
would need clearance to transition through the Class C airspace. If you are IFR, then it's not applicable anyway.

I'm just keeping my nose from pointint toward KMHT, as my video card won't allow a smooth flight over the 3rd party scenery and PAI
traffic there. If I took the standard run from CON VOR to MHT VOR, I'd be right over it at about 5 fps - no good.
So, as I am flying VFR, I should request clearance through the Charlie airspace when I'm turning final for RWY 14? No prob.
Re: VOR Navigation question - olseric - 02-02-2006
Theoretically, you should be low enough that you're under the 10nm ring if you're on final.
