EXTRA

The Wright R-1820 Cyclone engines
are essentially the same as those
used on the Boeing B-17 Flying
Fortress.

unnecessary, you cannot help but duck. The tips clear
the water by four feet. Each of the two nine-cylinder
Wright R-1820 Cyclone engines produce 1,425 horsepower and are essentially the same as those used on
the Boeing B-17 Flying Fortress.
Normal entry is made by hoisting yourself up a
boarding ladder and stepping through a hatch on the
left side of the rear fuselage. When flying an Albatross,
by the way, one becomes accustomed to using nautical terms. It is, after all, a boat. Ropes are called lines,
the nose is the bow, the rear of the aircraft is the stern,
and so forth. Once inside, you can turn right and go aft
through another hatch that leads into a voluminous
tail compartment. Turn left and you are led forward
through the cavernous cabin to a spacious flight deck.
From there, you can duck under the instrument panel
and through a crawlspace into the bow compartment.
There you are treated to a fabulous, bird's-eye view
of the outside world through this Albatross' Plexiglas
nose dome, which replaces the original radome.
Cummings graciously invited me to take the left seat
during my instructional flight. He has extraordinary
experience with big radial engines and knows how to
make them sing, so I was grateful when he volunteered
to start them. As on many seaplanes, engine controls are
mounted on the cockpit ceiling between the pilots' seats,
a configuration that simplifies routing cables and linkages to the engines. Taxiing requires differential braking
to steer the castoring nosewheel. Recovery from a taxiing turn, especially a tight one, is facilitated by adding
a tad of power from the inside engine when about 45
degrees of turn from the desired heading.
The Albatross yaws noticeably left during the initial part of the takeoff roll. This is easily countered
by advancing the left throttle slightly ahead of the
right. As airspeed increases and the rudder bites the
air more effectively, maximum power (51.5 inches of
supercharged manifold pressure and 2,700 rpm) can
be commanded by both throttles. Noise-cancelling
headsets are a must. Cockpit visibility is quite good, a
requirement for search-and-rescue operations.
The nose is rotated at 85 knots and then lowered
after liftoff to accelerate the Grumman to 105 knots,
the best single-engine climb speed (VYSE). Minimum
controllable airspeed following an engine failure (VMC)
is 92 knots. The rudder is hydraulically boosted during takeoff and landing to lend a helping foot in case
of a low-speed engine failure.
Because of the manner in which hydraulic plumbing is routed, the landing-gear legs retract irregularly.
The nosewheel retracts first, followed by each of
the tall main-gear struts-but not in unison. One leg
retracts into the side of the fuselage faster than the
other, resulting in asymmetrical drag that yaws the
airplane slightly right or left during retraction and
extension cycles. The split flaps also are hydraulic.
