Confined Area Approach and Landing (ASES, AMES)

• Airspeed: manufacturer's published approach speed, or in its absence not more than 1.3 VSO, +10/−5 knots with the gust factor applied (CA.IV.H.S7)
• Touchdown: proper pitch attitude within 100 feet beyond or on the specified point, with no side drift, minimum float, longitudinal axis aligned with the projected landing path (CA.IV.H.S11)

Read that speed tolerance carefully — this is one of the few landing Tasks where the commercial standard is still +10/−5 rather than ±5. The distance box, though, tightened from 200 feet at private to 100 feet.

Whether you can get out again. For most seaplanes, the takeoff run is usually much longer than the landing run, so a spot you can land in is not automatically a spot you can leave (FAA-H-8083-23 ch. 6).

Then think forward to departure conditions, not just current ones: land into a stiff breeze on small waves today and you may face a calm, glassy morning tomorrow, which is a harder takeoff. Land in the cool morning and depart in the hot afternoon and you lose significant takeoff performance to density altitude.

Inspect carefully from a safe altitude for shallow areas, obstructions, or other hazards — the handbook's line is that after touchdown is not the time to discover factors that make the area even smaller or less usable than supposed (FAA-H-8083-23 ch. 6). Include in the evaluation:

• Both the approach and departure paths
• Terrain that rises faster than the seaplane can climb, both for the eventual takeoff and in case of a go-around during the landing
• Whether there is sufficient room to make a gentle turn back over the water for the climb if climbing out over the terrain is not comfortably within the airplane's capability

Before you start the approach, not during it. The escape may not be straight ahead: it is often best to make a gentle climbing turn back over the water to gain altitude rather than climb out over a shoreline with rising terrain (FAA-H-8083-23 ch. 6). Fly the approach knowing which way that turn goes and at what point it stops being available — that point is your commit point.

Select and aim for a suitable touchdown point considering wind, landing surface, and obstructions (CA.IV.H.S5). Then establish the recommended configuration, airspeed, and trim, adjusting pitch and power to maintain a stabilized approach (CA.IV.H.S6). The stabilized-approach concept is the same one you fly on land — constant angle, constant airspeed, constant configuration toward a fixed aiming point (AFH ch. 9) — the difference is that the aiming point has no runway markings to anchor it.

Apply elevator control as necessary to stop in the shortest distance consistent with safety (CA.IV.H.S13). You have no brakes — deceleration comes from water drag, and how much of it you get depends on the pitch attitude you hold as the seaplane comes off the step. Back pressure as it decelerates also keeps the float bows from digging in.

Contact the water at the recommended airspeed with a proper pitch attitude for the surface conditions (CA.IV.H.S10). "For the conditions" is doing the work in that sentence: glassy water, rough water, and normal water each want a different attitude — see Tasks IV.J and IV.L. Touching down too fast with the nose too high produces skipping; correct it with back pressure and enough power to keep the floats clear, then reestablish the attitude and reduce power gradually (FAA-H-8083-23 ch. 4).

Rarely, and never on rough water or in strong winds. Downwind, the airspeed is the same but the groundspeed is much higher, which imposes excessive stress on the floats, increases the nose-down tendency at touchdown, and prolongs the water run because more kinetic energy must be dissipated (FAA-H-8083-23 ch. 6). The occasional justification is convenience or safety on the water — for instance avoiding a long slow taxi back to the dock — and it belongs to light-wind, smooth-water days only.
