C208 Exam Review Questions with Correct
Answers
When is continuing flight into icing conditions prohibited?
When any of the following occur:
● airspeed of 120 KIAS cannot be maintained;
● an airspeed decrease of 10 knots that cannot be remedied by application of max continuous
thrust;
● MEA or MOCA for current leg falls into area "C" of icing service ceiling (section 5 S1 of
POH).
What else acts in conjunction with the ailerons to assist in roll control?
Spoiler (up) deflection on the applicable aileron side, proportional to the aileron travel in
excess of 5 degrees aileron up, via an interconnected push rod connected to an arm on the
aileron bellcrank.
Where are the spoilers located?
The slop lip spoilers are mounted above the outboard edge of the flaps.
How the control surfaces are mechanically operated?
Through a manual (unassisted) linkage (standard bellcrank, push pull rod, cable, pulley). The
spoilers are connected to the aileron bellcrank via a pushrod.
What type of trim tabs do the ailerons incorporate, and where are the tabs located?
Servo tabs, which also serve to reduce control wheel forces, are located on both ailerons, with
a trimmable servo located on the right aileron only.
How is elevator trim accomplished?
,Via two elevator trim tabs utilizing the trim wheel, or the electric trim control.
How is rudder trim accomplished?
Via the trim wheel which is connected to the nose wheel steering bungee (as aerodynamic
forces on the rudder increase, any given selection of rudder trim will decrease due to the
elasticity of the bungee).
What is the minimum turning radius?
65' 4-7/8"
What is the steering range for the nose gear?
With only rudder approximately 15 degrees, with braking 56 degrees
How are the flaps operated?
Via a controllable selector operating an electric motor
What kind of flaps?
Large span, single slot type, incorporating a trailing edge angle and leading edge vortex
generator to reduce stall speed and enhance lateral stability
How is the standby flap motor actuated?
By utilizing the guarded standby flap motor switch to either UP or DOWN. By selecting the
guarded switch from NORM to STBY this deactivates the normal motor only. The standby
motor is always active.
What limitation exists with the standby flap motor?
The autopilot cannot by utilized with standby flaps, and there is no limit switch for the
standby flaps, so care needs to be taken not to continue operation of the standby motor switch
, after the flaps have fully extended/retracted. The flap position indicator located next to the
regular flap selector must be used to manually select the desired flap setting. The standby
flaps system is simply a standby electric motor—the flap jackscrew transmission has no
redundancy, so in the more likely event of a transmission failure, the standby flap system will
be useless.
What type of gear? How is shock absorbed?
Tricycle type fixed with a steerable nose wheel. Shock absorbsion is accomplished by the
main gear via the tubular spring-steel struts, an interconnecting spring steel tube between the
two struts, and the nose gear oil filled shock strut and spring steel drag link
What kind of brakes?
Each main gear wheel is equipped with a hydraulically actuated single-disc brake on the
inboard side of each wheel.
What kind of engine (Model, turbine type, Hp)?
The engine is a Pratt and Whitney PT6A-114A. It is a free turbine, two-shaft engine utilizing
a compressor section having three axial stages (7:1 ratio) and one centrifugal stage, an
annular reverse-flow combustion chamber, a one-stage compressor turbine, a one-stage
power turbine, and a single exhaust. The engine is flat rated at 675 shaft horsepower.
How many fuel nozzles and when do they operate?
There are 14 simplex nozzles, 10 primary and 4 secondary. 10 operate throughout the starting
regime, 4 after 30-35% Ng. Without the 4 secondary nozzles, the engine may hang at 30-35%
Ng during start. For operations from normal idle through max power, all 14 nozzles operate.
What is the maximum Ng?
