There's a somewhat curious (to my mind anyway) phrase I see in both the T-6 and P-51 manuals I was wondering about: to "jockey the throttle." As in "With this automatic regulator, you
don’t have to jockey the throttle to maintain a constant manifold pressure" from the P-51 manual. What exactly does this mean?

Re: To Jockey the Throttle
In this context, the verb "to jockey" means "to struggle with". Meaning you do not have to continuously make changes to throttle position to adapt to flight conditions; in the P-40, for example, the manifold pressure will change fairly dramatically if you climb or descend significantly without changing throttle position due to the atmospheric effects of altitude and variations on engine load. The P-51's throttle system is designed to minimize these inputs, allowing the pilot to focus on maneuvering or combat instead.ClipperLuna wrote:There's a somewhat curious (to my mind anyway) phrase I see in both the T-6 and P-51 manuals I was wondering about: to "jockey the throttle."

Just a guess, but I imagine this definition comes from the noun "jockey" being someone who rides a horse in a race...I bet that's a struggle!

Re: To Jockey the Throttle
Close - it refers to making a constant series of small adjustments, the way a jockey would work the reins and maneuver the horse through the field.

Comes to the same thing as Ian suggested - but it’s about something the jockey does while struggling.
