another ILS question

[Brett_Henderson]

[quote]OK Brett, mission accomplished. I did that flight a number of times coming in from different angles, as well as a few go-arounds and all worked well.

The point I'm making is.. I'm happy to help with this stuff.. but you gotta play fair

[RickG]

hmmmm.  Well it's mission NOT accomplished then huh?  Guess I didn't really understand quite what you had planned for me- .  Sorry. I am wondering tho if I am trying to do this but missing a step in the learning process. Are there other things to be learned before I start being able to do what you want?  Sorry to say the approach charts really don't make as much sense to me, as I'm sure they do to you.  Oh, and nope, I never dialed in the ILS.  

[Brett_Henderson]

Yeah.. there is a LOT of information on that chart..

I was ready to go through the chart.. step by step.  :)

Eventually having a shared-cockpit multi-player "checkride".. in 1 mile visibility  8-)


Look it over.. prepare your questions.. and we'll go from there  (no hurry)..

Much as I hesitate to insert myself, I've got to say this.

[RickG]

OK, I think I may be on to something here. I flew into Paine from a few different directions and this seemed to work. I set the vor frequency into the radio, then dialed the nav compass to 140. Flew a route that would take me a bit north, and when the compass said I was on the radial, I turned to 140, aiming for the runway.  Is that how that is supposed to work? It seemed good, but I'm unsure.  And, olderndirt, I do understand what you are saying, and couldn't agree more.

Mobius explained it well.. but I suspect you aren't completely familiar with VOR navigation. Maybe we should concentrate on that first ?

You hit a few steps that indicate that you get the general idea. Tuning tha NAV radio to the station is obvious. Radial selection is the next step. What you're calling a "nav compass", is the OBS. That selects the radial.

Now.. instead of just giving you a link to VOR tutorials.. let's use what we have. You've already executed the most basic VOR use...

[Brett_Henderson]

OK.. we're inbound heading (tracking) 120.. 50nm out at 7000msl

[Brett_Henderson]

So.. here we are.. we've reached 1020msl.. our DME tells us we're within 1.5nm.. NO RUNWAY IN SIGHT..

With or without DME.. we can see that the missed approach begins AT the VOR

[Brett_Henderson]

Just for reference.. her's the whole flight / approach...

[Mobius]

Yeah, what Brett said...

Since this plate does NOT say "DME required", I'm kind of surprised that decision height is even referenced by DME. Maybe Mobius can elaborate..

I'm not 100% certain, but my best guess is that the 1.5 nm reference to the DME is only for the VDP and and because the VDP isn't an essential part of the approach, the DME isn't required.

[Brett_Henderson]

Yeah.. I learn something new, just about every plate I study  TOO  :D

Thanks for the  DH / MDA  clarification  :)  

And yeah, it's supposed to be 080  (I fixed it)..  I had three versions of this approach running through my head as I was typing it..


In a round-about way.. you hit on something important.. there is a LOT left to pilot discretion.. but the prudent pilot doesn't deviate far from what's published.

(I can promise you that I've flown a VOR approach where  MY  procedure turn wasn't quite what's published  :-X  )

[RickG]

Hi again guys. Well, I printed and studied all my new info and did the flight, and --wow!

[Brett_Henderson]

Yeah.. that line was arbitrary; in that it could be ANY course, so long as it was directly
