Alt Air Without The Filter
Approach Aviation Development
Thursday said it has received FAA STC SA00206BO for an Alternate
Air system for all Grumman AA-5 Traveler and AA-5A Cheetahs.
The new “RAM-Air” Alternate Air System is designed
to provide an alternate source of induction air to the engine
without the restriction of the standard induction air filter. This
system allows the pilot to bypass the induction air filter
in-flight without the reduction in available engine power caused by
resorting to carburetor heat. A cable control in the cockpit
opens/closes a valve into the airbox that supplies unfiltered,
high-pressure air from the available air in front of the forward
engine baffling.
The high-pressure location of the inlet provides a source of
"Ram-Air" which has been tested to increase manifold pressure by
approximately 1/2+" Hg. This equates to 4-5 HP more horsepower at
altitudes where normally aspirated aircraft engines typically
produce 75% power or less. The system also increases the service
ceiling and effectively reduces the aircraft’s pressure
altitude by about 750 feet MSL.
"The “RAM-Air” Alternate Air System is an
outstanding and economical performance addition to the Grumman
Traveler and Cheetah." said Jeff Simon, President of Approach
Aviation Development, Inc. "Aircraft induction filters are always a
compromise of engine protection vs. performance. This system
preserves the integrity of the filter on the ground, while allowing
the pilot to take advantage of the increased power naturally
available in flight.”
The “RAM-Air” Alternate Air System, complete with
all necessary hardware, is available at the introductory price of
$750. Installation is very straightforward with a typical install
time of approximately 4-6 hours.
