chart heads-up

To get back into practice I fired up MSFS 2002 and grabbed a random (out
of date) chart to fly. It was the Bangor BGR ILS 33 approach (amdt 10B
03079, regular NOAA chart). So I gave the chart a quick glance, set up
the nav frequencies as listed in the chart, and went flying. It took a
few tries to get to fly right (the joystick needed calibration, I had to
re-remember where the settings all were...) but once on the approach, I
found the ILS needle was not agreeing with the ADF (for the LOM). IT
wasn't really agreeing with reality either, as confirmed by checking the
map view - it seemed like I was getting reverse sensing, and no glide
slope, and the chart is for a normal ILS. There definately was a
localizer, because I saw that needle on takeoff and coming around for
the hold in lieu (done with the ADF).

Well, on the chart, there is a balloon indicating the localizer
frequency of 109.5, and also (be careful!) the nearby VOR frequency of
114.8 (which I had in the standby). Nope, that wasn't the mistake, I
had 109.5 in the dial, I was on the right approach... since it was a sim
(and I was still adjusting the joystick and such) I continued down,
following the needle into neverland, then as an experiment crossing the
approach course (and landing, across the runway, while I was doing
that). Yep, reverse sensing, but no clue why. So, I studied the chart
and a few others.

There is an ILS 15 which uses the same frequency. As I understand it,
both can have the same freq, since only one is used at a time. Then I
saw it. On the upper left of the chart, it says LOC I-BGR 110.3, but on
the balloon, it says 109.5. So, which is it?

MSFS 2002 has 110.3.

A call to Bangor confirmed that the ILS 33 was once 110.3, but now it
has switched (both approaches - 15 and 33) to 109.5.

1: Look at the =entire= chart when briefing it!!

2: Is the chart in error, or is there a reason to have both frequencies
on the chart as depicted? (I can't think of any).
