Seaplane
Passenger Briefing
Many of my first-time passengers are nervous about flying
in a small planeespecially a seaplane. This is usually
exacerbated during the pre-flight briefing when I mention the
unlikely chance that we could be involved in an accident
on the water; but it's also an opportunity to ease that tension
with practical information and mention seaplanes'
excellent record in off-airport landings.
The
briefing should cover the necessary topics while emphasizing
the safety benefits
of seaplane flying. On the positive side, seaplanes have
several distinct safety advantages over land planes.
To
begin with, we have 44,000 acres of runway in front of us,
and almost the
entire flight will be
over this runway.
We
have the option of landing on water or land without serious danger.
Because the
floats
have
very strong keels, seaplanes can be landed on grass safely without
damage, or even on a concrete
runway if necessary with minimal risk to the plane or occupants.
Seaplanes
also have structural enhancements to withstand the rigors
of the water. The floats provide extra strength in front of
and below the cockpit, which protects the occupants in the
event of a landing accident.
The
most serious issue is getting out of a sinking
airplane. This is why pre-flight
briefing is crucial. Passengers must be prepared
for that unlikely eventthey must be shown how to find
and
release
seat belts, door, and window
latches while upside-down, and feel free to
kick out anything needed for egress.
Finally they must know how and when to inflate life jackets.
The
life jacket and the briefingknowing what do and when
in an emergency should
actually be a comfort to the wary first-time passenger,
giving him/her
a sense
of security in the face of a new and exciting experience.
Density
Altitude and Seaplanes
Summer
is arriving in Alabama. With humidity like warm butter and
temperatures heading into the 90s, the AWOSs are now forced
to tell us what the density altitude
is in the remarks section.
Any
airplane will have to contend with loss of cool dense air
to burn in the engine and to use
for lift and thrust. Planes will continue to fly off
the runway with about the same indicated airspeed as a 10
degree winter day, but the ground speed and true airspeed
will be considerably
higher as the density altitude increases. The engine will
produce less horsepower, the prop
will be less efficient, and the wings will have to work harder
to
fly in the less dense air.
Seaplanes
usually have the option of taking off directly into the wind,
plus the luxury of a nearly unending runway.However, there
is the added penalty of water drag, which increases at the
square
of speed. At some specific density altitude,
no amount of runway will allow a seaplane at a specific weight
to take off.
That altitude will be significantly less than the comparable
land plane, because the land plane does not have to contend
with water drag.
Chuck's Quick Tip: On
a calm day the water is much stickier than on
a day with some
wave action. Bubbles from waves under the pontoons
reduce drag. Stirring up the water by step taxiing in the take
off area can help. Taking off earlier in the day can help even
more. The only things that you can control in the heat of a still day are
weight
reduction and
the amount of time you spend swimming and relaxing by the cool lake water.

WaterWings
is now a dealer for Stormy
Seas inflatable life jackets.
We
did this in the interest of providing a safety service for
seaplane pilots. In the event of a seaplane
accident in the water, the first critical action is to get everyone
out of the airplane. A standard bulky life jacket can be a killer
if it inhibits exit from the upside down and sinking plane.
And they do little good in the airplane if not worn.
Inflatable
vests are lightweight and comfortable in the already tight
and sometimes warm cockpit, and their comfort encourages
wear. They can be inflated manually once clear of the sinking
craft.
This can
save lives in the water. WaterWings provides a Stormy
Seas inflatable vest for students to use while receiving our instruction.
Pilots
need to be aware that the President plans
to travel almost every day in support of his tax proposal,
so pay attention to the news. If the president
is going to be anywhere near your proposed flight path,
ask briefers specifically about temporary flight
restrictions in that area.
For 4th of
July travelers, words
to the wise from the FAA ...flying
and fireworks don't mix. We southerners do love
our fireworks, and because of widespread sales in
the region, the FAA sent hazardous-materials
agents out to fireworks retailers in the southeast to
distribute educational brochures and posters explaning
the dangers
of fireworks
aboard aircraft. The entire community outreach program
is titled: "Fireworks Don't Fly", and has reached
millions of people throughout the country. Penalties for
carrying these items onto aircraft
range from $30,000 to $500,000 plus prison terms.

Here's
this month's installment of the training guide- Part
Four: Taxi. We're
re-working the TG into a .pdf file for the best printout/study
tool. Still working on the PowerPoint, plus delving into video
training clips. Stay tuned...

The Seaplane Pilots
Association is offering a special
6 month trial membership to WaterWings students, which includes
3 issues of Water Flying
magazine. When you come for your instruction, ask Charles
to put you on the sign up sheet.
