🔍 Key Concepts

• Trace the piping from No. 1 pump to see which cylinder ends it actually supplies (look carefully at the letters on the pipes and cylinder ends). • For left rudder, decide which way the tiller and rudder stock must rotate, and then which ram must extend and which must retract to make that rotation happen. • Remember that the cylinder end that is extending is the one that will be under pressure; the opposite end on that same cylinder will be relieving/returning to the tank.

💭 Think About

• From the illustration, when you order left rudder, does the tiller arm move so that the port side goes forward or aft? Use that to decide which side of each ram is pushing. • Once you know which ram is pushing, ask yourself: for that ram, is the inboard or outboard cylinder end being pressurized by No. 1 pump during left rudder? • Compare the letters on the pressurized and relieving ends of the active cylinder with the answer choices to see which statement matches that condition.

✅ Before You Answer

• Verify which unit is No. 1 pump (port or starboard power unit) and exactly which cylinder ends (lettered ports) are connected to it. • Double‑check the direction of rudder rotation for a left rudder command as drawn in this top‑view sketch. • Confirm which cylinder end is pressure and which is relief/return for the active cylinder, then match those specific letters to the options.
