DESCRIPTION AND OPERATION OF COMPONENTS
GENERAL
The Executive 21 is a single engine four-place low wing, re-
tractable tricycle landing gear airplane. The design and opera-
tion of this aircraft are conventional with few exceptions. This
section will describe some of the components of the aircraft
and operating details.
PROPELLER
The Executive 21 uses an alunlinu~nalloy constant speed pro-
peller of
74
inch diameter. The pitch of the blades is controlled
by engine oil pressure which acts to increase blade angle of
attack and thereby control engine speed. The propeller control
in the cabin operates the propeller governor which controls the
oil pressure provided to the propeller hub. The governor
ser-
ting functions to maintain the engine at a constant speed by
actuating blade angle of attack. In essence then, the function
of the propeller control in the cabin is to regulate and maintain
the rotational speed of the engine at a desired setting.
ENGINE
The Executive 21 is powered by the Lyconling
200
hp
10-360-A
1A
four cylinder engine. This engine uses 100/130 octane fuel.
Four rubber bushings on the aft side of the engine provide
mounting and vibration isolation. Engine ~iianifoldpressure
is
regulated by the push-pull throttle control on the panel.
POWER
BOOST
A
unique Power Boost feature of the Executive 21 provides in-
creased manifold

h ed by pulling the Power Roost control
out, which causes induction air to by-pass the engine air filter
to perinit the engine to operate
on
direct ram air. Because
the engine will be operating on unfiltered air when the Power
Boost is used, it should be operated only in clean, dust free

air at altitude, and turned off for take-off and landing. Because
the Power Boost is effective only when the throttle is in the
fully opened position, its advantages generally will be realized
at altitudes above
5,000
feet where flight is often with full throt-
tle.
A
light is provided on the panel by the Power Boost control
to remind the pilot to push the control in (to filtered air) before
landing. This light will come on when the gear
is
lowered
while Power Boost is on.

WARNING
Do not
fly
this aircraft in icing conditions.
Turn Power Boost off when icing conditions are
inadvertently encountered. Icing conditions prevail
any time the temperature and inoisture conditions
coixbine to produce the possibility of impact ice.
Using unfiltered induction air when flying in snow
or other
IFR
conditions can be hazardous. Snow
can accumulate in the fuel injector impact tubes or
inoisture can freeze in the passages under icing
conditions and cause loss of power. Therefore it
is imperative that the Power Boost not be used when
flying in sleet, snow, rain, or i~~oisture-ladenair
near freezing teii~peratures. Under these condi-
tions ice can for~liin the inlet duct or fuel injector
unit even though no visible moisture
is
apparent on
the airframe.

FUEL-AIR
MIXTURE
The fuel injector unit of the
10-360
engine has provisions for
adjusting the fuel-to-air ratio as required at,different altitudes.
The fuel-to-air ratio (mixture) is regulated by the hexagon
shaped push-pull control located between the throttle and pro-
peller controls in the cabin. This control has a vernier adjust-
nlent feature for obtaining precise mixture settings. An exhaust
gas temperature gage is provided to indicate the optiinurn mix-
ture setting.
ENGINE
COOLING
The engine baffling directs air flow over the cylinders for cool-
ing in flight. Cowl flaps are provided on the lower cowling to
allow more free air flow on the ground and during low speed,
high power conditions (i.e., climb conditions). Cowl flaps
should always be open on the ground, and prolonged engine
operation on the ground should be avoided to prevent engine
overheating.
A
push-pull cofitro'i is provided below the in-
strument panel and to the right of the pilot for operation of th'e
cowl flaps.
