Lear 24B Autopilot Glide Slope Capture

Recommended Posts

Has anyone figured out the correct procedure to catch the glide  slope with the A/P in the Lear 24B? Scenario:  Level at an altitude BELOW the G/S. Speed 160kts. A 30 degree intercept to the localizer. A/P on, altitude hold on, and approach mode on with G/S armed.  I capture the localizer, but fly right through the G/S. I then fly back around for another go at it. Everything is the same on the autopilot EXCEPT when the copilot (MCE) announces glide slope and localizer active I turn off altitude hold on the A/P and it captures the glide slope perfectly. Is this the real world example of a Lear 24B A/P? I would have thought that the A/P approach mode would have turned off the altitude hold with G/S active.

 

Any comments would be appreciated & thanks.

My understanding is that this is realistic for a 1960's autopilot. You must switch the Altitude hold when to capture the glideslope. I do this just as the glideslope needle hits the mark and the transition is smooth.

 

I'm sure there is a post earlier about this.

Thanks Peter. As long as it's realistic I'm good with it.
