Do you have enough bleed air with throttles at idle?

Thrust curve is not linear with throttle position so some rpm above
idle might be required in some birds???


The Lear 60 has big Pratts on it so it does have enough bleed air to run
everything at idle. The 50 and 30 series Lears I flew didn't usually have
enough bleed air at idle to run both pressurization and anti-ice. Like you
said above, on those planes you had to have some power greater than idle to
hold the cabin with anti-ice on.

Now on the old 20 series lears I hear you had to have the rpm up just to
hold cabin altitude.

Hope that answers your question,
