getting red airspeed limit to show on round dial indicator

[john brunke]

I've attached a couple of photos of the airspeed page and the indicator. Let me first clarify that after taking
these shots I read on page 84 of the manual that the MAX indication should be set to 240Kts. I went back in
and did that and saved the data.

I'm having trouble getting a red airspeed line or even small red arc to appear on the indicator. I'm sure it's
operator error on my part, but I would appreciate some help.

Thanks,
John

With the old AF-3500 non "S" CPU the largest number that works with the Analog gauge is 205 kts.

Why are you trying to set the Vne for a RV-7 at 220 kts IAS?

Van's airspeed gauges are printed Vne = 180 kts

Don't forget that Vne and aircraft flutter speeds are actually TAS not IAS!!

Rob,

I was just trying to get any value set to see if I could get a red line.
Didn't know there was a limit of 205 on the analog gauges. Is that in print somewhere?

I posted a question a few weeks ago about setting the hobbs and tach and would never had
figured that one out unless this forum existed. I know this system is old now, but its all new
to me. I would bet the newer system is easier to set up, but I'm just trying to finish this airplane
without spending too much more money.
