Lectures Flashcards
What is the turn radius of the Seminole?
33 ft
Why does the Seminole have a T-tail versus a regular tail configuration?
Keeps the stabilator out of the prop wash
What is one disadvantage of a T-tail configuration?
Little Rudder control at slow airspeeds, so you need LARGER control inputs
Why do we have Cowl Flaps on the Seminole?
To help control CHT and prevent Thermal Shock/Shock Cooling of metals, internal stress and cracking
The Nitrogen charge brings the prop. to a ____ pitch and a ____ rpm
HIGH pitch
LOW rpm
Engine oil pressurized by prop governor is boosted to ___ psi
275 psi
Counterweight brings the prop. to a ____ pitch and a ____ rpm
HIGH pitch
LOW rpm
How many TOTAL gallons of fuel can the Seminole hold? How many of those are Usable?
110 gallons Total
108 Usable
Sluggish propeller control and propeller overspeed with poor RPM recovery after rapid throttle application are indications that?
The Nitrogen charge is low
A windmilling propeller reduces single-engine climb performance by ______ FPM
-200 fpm
Feathering time on the Seminole W/O the unfeathering accumulator installed is __ seconds
6 seconds
The purpose of the Anti-Feathering Pins is to prevent:
The prop from feathering during shutdown
How many fuel pumps are there in the Seminole fuel system?
4
When you select “x-feed” on 1 of the fuel selectors on the Piper Seminole, what happens?
With both engines running, you are drawing fuel from 1 tank only
What is the proper procedure for crossfeeding fuel from the Left Tank to the Right Engine on the Piper Seminole?
- Left Fuel Selector is turned ON
- Right Fuel Selector is placed on X-Feed
How are turbochargers driven?
Turbocharging is driven by exhaust air passing over the turbine
How would you know if the turbocharger (compressor) system has failed in a twin engine airplane?
The affected engine would not be able to maintain the same M.P. as the unaffected engine
Why should you idle a turbocharger engine for a few minutes before you shut it off?
To allow the compressor to be lubricated and cooled as the turbine wheel spools down prior to shutting off the engine
What does 91.103 constitute in regards to Preflight Actions
DRAWFP Delays Runway Lengths Alternates Weather Fuel Performance
On the airspeed indicator, what speed does the Red radial line indicate?
Vmc calculated under the specific set of certification conditions (cannot be wholly relied on each flight)
Tell me about Carburetor Heat. How does it affect performance? What kind of air? Where does the heat come from?
- RPM drop
- Unfiltered air
- Heat comes from shroud around #4 cylinder exhaust
If you experienced gradual RPM manifold pressure loss, RPM loss and engine roughness, what could possibly be the cause?
Carb icing!
When is supplemental O2 required under Part 135:
Pressurized a/c:
- Above 10,000-12,000 for 30mins+
- Above 12,000 at all times PILOTS must use O2
Unpressurized a/c:
- Above 10,000 (follow pressured a/c reqs.)
- Above 25,000-35,000 must have quick-don masks OR have 1 pilot wearing O2 at all times
- Above 35,000 1 pilot wearing O2 at all times
What are the VFR weather minimums for Class G airspace under Part 135?
- 500’ horizontally AND ABOVE of clouds
- Ceilings 1,000’ and 2sm vis
What are the IFR weather TAKEOFF LIMITS under Part 135?
- May not takeoff IFR from an airport with conditions AT OR BELOW IFR LANDING MINIMUMS, UNLESS an alternate within 1 hour had been filed!
