>While planning my avionics stack I discovered that there is not sufficient
depth behind the panel for any UPS Aviation Technologies nav/comm,
GPS/comm,
or transponder. Each of these requires approximately inch (12 mm) more
than is available behind the panel to the firewall. Not wanting to make
unnecessary cuts into the firewall for clearance my remedy is to add a
spacer between the panel flange and the firewall. According to Neville
this
is OK as long as the relocated panel does not interfere with full forward
stick motion.<
I have the UPS Apollo SL40 and was able to fit it to the centre part of the
panel. The small extra distance from the firewall you need is acheived if
you install the panel using the Europa Club mod. This way of mounting the
panel makes removal and refitting much easier, hides the screws and makes
the panel stronger without significant weight penalty. The clearance from
the stick is ample. I haven't checked to see if the face of the instrument
panel is parallel to the firewall. If it isn't the close tolerances may
mean the vertical position may vary the clearance from the firewall. My
radio is fairly low on the stack below the Skyforce Colourmap and the
uMonitor. Although the SL40 uses a lot of depth it is only 1.125" high and
only uses half the width of the box for the radio so the same case can also
house a VOR as well without using more panel space. The performance of the
radio even with the standard Europa tape aerial is fine and the integral
vox intercom is as good as any external intercoms I have come across. I
also find the monitor function (listening on the standby frequency) very
useful as well.
