Lear Jet 45 Question

| I hope not too stupid a question......
In the Lear Jet 45..... On the HSI with the Course Deviation Indicator
(CDI) centered, how do you know whether the (green) arrow is pointing to a
course that will take you To or From the tuned VOR?

If I understand the question, the tuned station will be in the direction
the arrow is pointing no matter if it's in the top or bottom portion of the
HSI.

| Papa George,
I'm missing something very basic here, I guess.
Hypothetical situation......
You tune and identify a VOR. You turn the HSI until the CDI centers. Let's
say the arrow is pointing to 170 degrees. You then turn the HSI until the
CDI centers again. The arrow now points to 350 degrees. If I want to fly To
the VOR, do I turn to a heading of 170 or 350 degrees?

| You can't get that just from the VOR - that just tells you that you are on
or off the airway. When it's centered you fly two directions or headings -
toward the VOR or away from it. Which one - the 170 or 350 will depend on
which way your objective is. It the airport is toward the northwest you
set the OBS to 350 and then fly that course.

Unless you want to consult the GPS, I suppose you just have to fly along
the radial and see what happens with the DME (if the VOR is equipped
with DME).
I just checked, the arrow head on the CDI "needle" aways points in the
same direction the course selection arrow is pointing.
In regards to the radio frequency legibility, what screen resolution are
you running the simulator at? If you can maintain a usable frame rate
some instruments are only legible when the resolution is cranked up a
bit. Many of the DME/closing speed/ETE gages on main panels have the
same problem.

| When you say arrow, I think you mean the CDI pointer. Then there is the
smaller, shorter arrow in the HSI. That is the to/from arrow.
With the CDI centered and the arrow pointing to the course selected by the
pointer, that course if intercepted will take you to the VOR. Think of that
pointer as the course seletor pointer. If the small arrow is in the bottom
half of the HSI and pointed toword the tail of the arrow that course will
take you away from the station.
The quickest way to determine the course to the station look at the RMI
pointer and read the heading under the arrow. That is the direction to the
VOR. Assuming you have the correct frequeny tuned of course.
In you discription the only way to tell if it will take you to or away from
the station is to look at the small to/from arrow. Crosscheck the RMI if it
is available. PapaGeorge

Gday Dave
Had a look at the default Lear, did some tests and found that
along the bottom (under the CDI) you should see distance to VOR, your
speed and the bearing. If the bearing is approximately your course
setting, you are flying toward the VOR. If the bearing is 180 degrees
out, you are flying away from the VOR.
Another way to check is to set your NAV 2 to same freq as VOR and the
blue arrow on the CDI pointed towards the VOR at all times
When I say approximately, I believe the closer you are to the VOR the
more error is introduced and there was something about magnetic
deviation too, but it's been too long to recall properly.
hope this helps

| If you dont know which direction the VOR is to your present position you
will need a TO/FROM indication to confirm it.
Its no good saying I want to fly on a bearing of 170 if you are mistakenly
on the southern side of the VOR as you will fly away from it. Haven't used
the Lear in a while so not sure if it has TO/FROM, must have something
