These 10 free AMES questions are organized by exam domain, so you can see how each part of the Multi-engine Seaplane Rating (AMES) blueprint is tested. Reveal the answer and explanation under each question.
A seaplane is taxiing out of a U.S. harbor toward the open sea through a channel marked with conventional lateral buoys. It is not following an Intracoastal Waterway route. How should the pilot use the red, even-numbered buoys?
Correct answer: B - Keep them to port, with their numbers generally decreasing toward the sea.
Both engines develop normal power as a twin-float seaplane accelerates. Moving from the plowing attitude to the correct planing attitude produces a marked improvement in acceleration, although the floats still contact the water. What accounts for that improvement?
Correct answer: D - Water separates at the step, reducing wetted area as hydrodynamic lift supports the floats.
On arrival at a coastal seaplane base, a pilot sees smoke from a shoreline chimney streaming east. In the adjacent channel, anchored boats point their bows east while partly submerged debris moves steadily west. Which interpretation reconciles these observations?
Correct answer: C - A westerly wind and a westward current strong enough to dominate the boats' alignment.
During a float inspection, the bilge pump removes small amounts of water from several compartments but draws nothing from one that normally yields some water. The same pump works in another compartment immediately afterward. What has the dry pump result established?
Correct answer: A - It has not distinguished a dry compartment from a damaged or disconnected pickup tube.
A multiengine floatplane lifts off from moderately rough water at its recommended rough-water liftoff speed, still below VY. Both engines show normal power, the airplane is controllable, and ample unobstructed water remains ahead. Which flight path preserves the intended rough-water takeoff technique?
Correct answer: A - Remain in ground effect while accelerating to the recommended climb speed.
During a Commercial AMES VMC demonstration at a safe training altitude, stall warning occurs at 84 KIAS while directional control remains intact. The airplane's red-line VMC is 76 KIAS. The maneuver was correctly configured, with one engine at idle to simulate failure. Which recovery conforms to the ACS?
Correct answer: D - Reduce operating-engine power sufficiently and decrease angle of attack to regain airspeed and control.
For an engine-out departure assessment, a multiengine seaplane's AFM predicts 420 ft/min at the recommended OEI climb speed of 84 KIAS, corresponding to 105 KTAS. A 15-knot direct headwind is expected along the departure track. The operator requires at least 260 ft/NM through the obstacle sector. Assuming these conditions remain constant, which assessment is correct?
Correct answer: B - 280 ft/NM; the predicted gradient exceeds the requirement.
A conventional twin has equally rated, laterally separated engines and propellers that both turn clockwise as seen from the cockpit. At high positive angle of attack, P-factor moves each propeller's effective thrust toward its descending blade. Which engine is critical on the basis of this geometry?
Correct answer: B - The left engine, because the surviving right engine's thrust acts through the longer yawing arm.
An AMES pilot establishes the flight manual's glassy-water landing attitude, airspeed, and descent rate before passing the last reliable height reference. The landing lane is clear, a distant horizon remains visible, and ample landing distance is available. Over the mirror-smooth surface, the pilot still cannot judge height accurately. How should the final descent be flown?
Correct answer: C - Maintain the glassy-water landing attitude, using power as needed to hold the prescribed airspeed and descent rate until contact.
An amphibious twin's landing check is interrupted when the intended runway closes. The pilot elects to use a nearby lake. On downwind, the gear-position lights are green; in this airplane, green means down and locked. The gear system is operating normally, and there is time to reconfigure. What response addresses the changed landing surface?
Correct answer: C - Retract the wheels and verify their actual position using the approved water-landing checks.
