LAND TAKE-OFF:  The Seawind 300C accelerates quickly down the runway.  At 60 knots (70 mph), a one-hand rotation is applied and the craft lifts off between 60 and 70 knots.

ROTATION:  Because of the high thrust line above the vertical c g and the rotation about location of the main landing gear axle, flying boats require higher rotation forces on land take off.  Once the wheels leave the ground, the rotation pivot point moves forward to the main spar location (about 14 inches) forward and the yoke force reduces about 15 pounds, and you can relax the elevator force.

CLIMB:  With the landing gear retracted and the flaps set to zero, the Seawind 300C will climb quickly to altitude, at 1250 fpm.

CRUISE:  The cruise configuration is with flaps reflexed to minus 10° up, required by its laminar flow airfoil.  Once trimmed straight and level, the Seawind 300C is truly a hands-off machine.

LAND LANDINGS:  Landings on land are normal with a gear-down speed of 120 knots (140 mph) and a flap-down speed of 110 knots (120 mph).  The pattern speed is 80 to 90 knots with flaps at 20° as you apply a little up trim to what feels naturally comfortable.  Full 30° flaps are applied and the propeller is set to high rpm on the final leg with the speed at 80 knots.  After crossing the threshold at 70 knots, flare to a touchdown speed of 55  to 60 knots.  A significant ground effect allows you to gradually raise the nose to bleed off the speed at about 2 feet above the runway.


The perfect landing attitude.

WATER LANDINGS:  Landings on water are virtually the same as land landings; except, of course, the landing gear is up.  Final approach is at 80 knots, 8 to 10" M.P. with full 30° flap, at high rpm.  A few feet above the water, the Seawind 300C is leveled and slowed to 70 knots, and the nose is raised to about four to six degrees.  Throttle back, and the Seawind 300C lands on the step at 55 knots.  Visit the Water Safety section of the Flight Safety page.

STEP TAXIING:  Step taxiing can be performed with full flaps or zero flaps.  The time onto the step is a couple of seconds quicker with zero flaps.  The wings are held level and steering is performed with the air rudder.

WATER TAKE OFF:  Water takeoffs are comfortable.  The Seawind 300C rises onto the step virtually by itself.  A bit of up elevator is applied as the bow wave moves by the step.  The elevator control is relaxed, and with full flaps at 55 knots, the Seawind 300C flies itself off the water.  The rotation point of the hull on the water is near the main spar and so the rotation forces are much lighter than on land. Allow the speed to increase, and the Seawind starts to climb.  Then gradually raise the flap to 0° for the climb setting.

TURNS:  Like any amphibian of high thrust line aircraft, turns should be coordinated with rudder and ailerons.

PITCH CONTROL:  The Seawind 300C has superb pitch control.  A full power go around just above the water is easily executed with one arm pull back.  The nose will not drop.

CROSS WIND LANDINGS:  Carry a little power in a crosswind landing to make the air rudder more effective.  Idling the power tends to block the flow over the air rudder.  So, apply a little power, 10 inch of Hg. manifold pressure.

STALLS/SPINS:  The Seawind is the only single-engine general aviation aircraft under 6000 lbs. With a Stall Prevention System (SPS).  The SPS has two special design wing transducers which signal two analog computers.  When either transducer senses that the aircraft is within 5 knots of a stall, it sets off a stick shaker to warn the pilot of an approaching stall.  If the pilot does not take corrective action and the second transducer senses a stall, then a stick pusher moves the yoke forward lowering the nose to avoid a stall.  If an aircraft does not stall, it cannot spin.
