5.25 Please help with the arrows on the Lear HSI!
From FlightSim
THE "LEAR HSI" IS SO "EASY" TO USE THAT IT'S MAKING ME FEEL LIKE AN IDIOT! FIRST TIME WITH THIS PIECE OF AVIONICS. I'VE PRINTED OUT THE FLIGHT SCHOOL EXPLANATION AND STUDIED IT BUT SOMETHING'S NOT GIBING HERE. THEY TALK ABOUT "YELLOW ARROW" BUT I DON'T SEE ONE. AFTER TAKEOFF I CAN'T GET THE DEFLECTED OR MIDDLE PART OF A GREEN ARROW TO DO WHAT I THINK IT'S SUPPOSED TO DO. CAN ANYONE MAKE ALL THIS ANY EASIER, PLEASE?
Adjust the "course" dials to align the arrow segments. This is only possible if you are tuned into and receiving the VOR. Once they are aligned they will point to the VOR location. You can either manually change course to fly toward it or hit the NAV button on the autopilot and it will happen automatically. On the 737-400 panel it is yellow. I thought it was on the Lear also, but maybe it's green. If you are tuned to an ILS the arrow segments won't align until you are on the beacon heading. You can adjust the course to the runway heading, but it shouldn't be necessary.

The yellow arrow being referred to is the one in the Bell and
737...sound like you're in the Lear, or something that's using it's
avionics. So, the green arrow (actually, I thought it was
blue...hmmm..) is actually the yellow arrow. Ok, here's a quick down
and dirty on the HSI. Your arrow is your omni bearing selector like
you have on a VOR head. You use the same commands in FS (V+1 or 2)
to change it. So, now you turn the thing 'til the needle in the
center lines up with the arrow...right smack in the center of the
HSI. Now you just fly with your heading on the arrow (or left or
right of it...depending on x wind). You'll also see a to/from
indicator on the HSI. This is a small white arrowhead. If it's
pointing at the head of the big yellow arrow, you've got a "to"
indication. If it's pointing at the tail of the big yellow arrow,
that's a "from" indication. One thing to know with an HSI that's
very different from a VOR. IF you have a "from" indication on a VOR,
you fly opposite the needle (ie: needle point right, you steer left).
If you have a "from" indication on the HSI, you fly toward the
needle. If you have a "to" indication on the HSI you STILL fly to
the needle (or I should say the part in the middle of the HSI that
moves...not the needle). Now, say you're intercepting a VOR radial
with the HSI. If you think (or know) that you're somewhat close, just
put your heading on the indicator....if it's fully deflected, that
will give you about a 45 degree intercept course. But, you need to
make sure you're not a long ways off the radial. Something else you
should know. When you've got a "to" indication and the indicator is
centered, if you look at the tail of the HSI arrow, that's the VOR
radial you are on. That will help you if you ever do instrument
approaches. Well, I probably just confused the heck out of you. If
I did, yell at me and ask me to explain something more clearly and I
will be more than happy to.

The problem is that much of the info in help is for FS95 and some
things have changed. Don't worry though, the HSI is really pretty
easy to use. First of all in FS98 the arrow is green and not yellow
(as stated in help) so if your getting a green arrow your on the
right track.
Next make sure you have the heading set on the HSI to the radial you are trying to track. If the center section of the arrow is not in the center then you need to change your planes heading so that you are flying toward the section of arrow. As you approach the correct radial the center section of the arrow will start to move toward the center where it belongs. It just like chasing the needle in the OBI for one of the Cessnas.
Hope this helps JDHef
If you don't see the yellow arrow on the HSI (it usually has the
center segment displaced) maybe you're not tuned to a nearby VOR
frequency on the NAV radio.
