Maybe I missed something in the documentation.....anyone know why my glideslope doesn't work?

I noticed this on my brief flights. This is in the documentation (regarding the ILS gauge):

I'll give it a try and see if this solves it. I suspect it will!

I don't know why the Smith's Flight System was arranged like that, but it was.
I still find it quite difficult to use, and I understand it. (a bit)
Fraser's the real SFS expert. ;-)

If you can, set the ILS in NAV1 & 2 to make sure.

Radio Selector.
The radio selector is used to select Nav1 or Nav2 information to the Flight System. The top switch is selected to 1 or 2 as desired. Note that the Azimuth Director and Pitch Director will only respond to Nav1 displacements so if Nav2 is selected the radial and glide path must be flown raw. When the switch is Off, the Azimuth Director will respond to differences between the Heading Pointer and Heading Index on the Beam Compass. A magnetic indicator shows the input to the Flight System.



Director Horizon
1. Beam Flag. Visible when a steady VOR/Localiser signal is received
2. G/P Flag. Visible when a steady Glide Path signal is received.
3. Pitch Director. Shows demand for pitch corrections relative to GP deviation.
4. Horizon Bar. Moves relative to aircraft bank.
5. Pitch Pointer. Moves vertically relative to aircraft pitch
6. Pitch Scale.
7. Bank Scale.
8. Azimuth Director. Shows demand for heading and bank corrections.
9. Ring Sight. Placing the Ring Sight over the Azimuth Director will correctly bank the aircraft.
10. Pitch Scale Setting Knob.

Course Deviation Indicator
The CDI shows deviations from the course and glide path of a facility selected on the OPPOSITE Radio to that selected on the Radio Selector; i.e. if Nav1 is selected to the Flight System, Nav2 information will be displayed on the CDI and vice versa. It is recommended that for ILS approaches where a VOR bearing is not required, that the ILS be tuned to both radios.
