Safety by Design - Not by Default
Airframe
- Utility Category - The highest level of non-aerobatic certification requires
that aircraft in this category must be capable of withstanding higher load
limits and G forces. No other composite or metal aircraft certified since 1968
has been certified to the Utility Category standards. Other aircraft are only
certified at the lower load limit requirements for Normal Category. Safety
by Design - Not by Default.
- "No Single Point of Failure" is the safety philosophy that Columbia
Aircraft airframe and systems are designed around. A deeper understanding
of what makes an aircraft design safe leads to an educated aircraft purchase
decision. At Columbia Aircraft our approach is Safety by Design - Not by Default.
- Redundant Spars -
All Columbia aircraft have dual wing spars, 8 flap hinges, 6 aileron hinges,
3 rudder hinges, 4 door latches, 2 wing spars, 2 horizontal spars and even
spars in the horizontal stablizer. Other aircraft may also have two wing
spars but the Columbia spars are equal in design strength, length and structure.
Each Columbia spar is capable of supporting the aircraft's entire load limit
individually thereby making this important structural element completely
redundant. Safety by Design - Not by Default.
- Spin Resistance/Spin
Recovery - Only aerobatic aircraft are certified to perform spins. However,
each FAR Part 23 certified aircraft must demonstrate spin characteristics
for safety. Columbia 350 and Columbia 400 models have successfully demonstrated
spin resistance/spin recovery for their respective type certification without
the need for a supplemental recovery system. Safety by Design - Not by Default.
- Wing Design - The unique shape of the leading edge
is a NASA-proven compound airfoil. The outboard section of the wing flies
at a lower angle of attack than the inboard section to improve aileron authority
and low speed handling. Safety by Design - Not by Default.
- Wing Loading/Aspect Ratio - Columbia
aircraft have the highest wing loading in their class. This design element
directly translates into a more stable and comfortable ride in turbulence.
Additionally, efficient wings with a high aspect ratio, like that those on
Columbia aircraft, provide the best glide characteristics. Safety by Design
- Not by Default.
- Carbon Fiber- Carbon
fiber is a composite material typically 3 times stronger than aircraft aluminum.
When you visit the Columbia factory, you'll see a liberal use of carbon fiber
used to help provide the additional strength that enables Columbia aircraft
to achieve Utility Category certification standards rather than the lower
Normal Category standards. Safety by Design - Not by Default.
- Lightning Coverage & Static Wicks - 100% of Columbia aircraft surfaces
(fuselage, wings and flight controls) are covered with lightning mesh to
effectively and safely dissipate the affects of a lightning strike without
concentrating the tremendous heat into narrow channels of lightning mesh along
the fuselage. Consequently, Columbia aircraft have earned the same lightning
certification as all-metal aircraft. Static wicks on the trailing edge of the
wings allow static build-up to be discharged safely without affecting avionics
functionality or disrupting other electrical systems. Safety by Design - Not
by Default.
Cabin Safety Features
- Roll Cage - Modern aircraft conform to FAR Part
23 regulations and are certified to much higher standards than older aircraft
designs that have been "grandfathered" into their Part 23 certification.
Part of the new certification standards require that modern aircraft have
cabin integrity that includes a roll cage to protect occupants in the event
of a roll-over. Columbia aircraft have an integral roll cage that has been
tested to maintain its structural integrity to 3 times the force of gravity.
- Emergency Egress / Door Release - Protecting cabin occupants
is paramount but so is the ability to exit the cabin if the fuselage comes
to rest inverted. Columbia aircraft are designed with a unique emergency
egress system that can be utilized by rescue workers or first responders
from the outside of the aircraft. Safety by Design - Not by Default.
- 26 G seats - Modern aircraft conform to FAR Part
23 regulations and are certified to much higher standards than older aircraft
designs that have been "grandfathered" into their Part 23 certification.
Compare a modern seat to a seat designed years ago and the value of the
new certification standards becomes obvious. Columbia aircraft seats have
been designed, sled tested and proven to withstand tremendous force of
26Gs in a horizontal plane and 19Gs vertically. Safety by Design - Not
by Default.
- Windshield - Columbia aircraft have a windshield that
is a full .312" thick (compared to other that are only .125" - .250").
The additional thickness actually makes the windshield a structural element
of the cabin and helps improve sound proofing. Safety by Design - Not by
Default.
Systems
- Redundant Electrical Systems - Other modern aircraft
advertise being "all-electric", however the dual electrical systems
on Columbia aircraft are fully-redundant. The critical difference between
dual and redundant is that many aircraft with dual electrical systems have
a lesser back-up electric system that cannot operate all standard systems.
Consequently, the pilot is forced to make critical decisions to shed power,
pull breakers and/or run a partial panel. The second electrical system on
Columbia aircraft is a fully redundant system equal in every way to the other
system. Thus either electrical system on a Columbia aircraft can start the
aircraft and run all standard systems independent of the other electrical
system. Dual 60 amp alternators, dual 15 amp hour batteries, dual busses
and dual wiring harnesses ensure that an electrical emergency will not force
the pilot to shed power, pull breakers, turn off critical standard systems
or fly a partial panel in the event of an electrical emergency. Safety by
Design - Not by Default.
- Flight Controls - A close inspection of any Columbia
aircraft reveals that each aileron has three – not two – attachment points,
rudder has three attachment points and each flap has four attachments. Thus
a single point failure will not render the flight control inoperative. Safety
by Design - Not by Default.
- Flight Control Rods - Aileron and elevator inputs of
all Columbia aircraft are transmitted through the positive connection of
control rods. Rudder inputs are transmitted through special cables inside
two synthetic sheaths. Neither the control rods nor the specially encased
rudder control cables require annual rigging adjustments or maintenance like
conventional cable systems. Safety by Design - Not by Default.
- Rudder Limiter (350 only) - Another innovative safety
feature on Columbia aircraft is the rudder limiter. An electronically actuated
piston limits rudder pedal travel in the fringes of the operational envelope
that may lead to an inadvertent spin. Safety by Design - Not by Default.
- Fuel System - Pumps and back-up fuel pumps have been
the aviation norm for decades. Another safety feature that makes the Columbia
fuel system unique is the fact that the internal fuel cells are protected
fore and aft by the strength of the dual redundant wing spars. Safety by
Design - Not by Default.
