414 CRITICAL ALTITUDE
20000
Why does the 414 have a higher CRITICAL ALTITUDE than the 401 (same engine TSIO-520)
414 has an engine drive INNERCOOLER
How does the 414’s INTERCOOLER increase its CRITICAL ALTITUDE?
InnerCooler provides cooling to the compressed air as it goes into the engine, which increases the amount air available to the engine at higher altitudes.
What type of De-Ice equipment do we have on the 310 and 414?
Certified for “Known ICE”
Windshield heat, Wing Boots (inboard/outboard wings plus vertical & horizontal stabs), Prop Heat, Pitot Heat, Stall Heat
W
It
What kind of engines does the 310 have?
Continental IO-520 (non turbos)
What kind of engines does the 414 have?
Continental TSIO-520 (turbo-charged)
414 also has the innercooler
The Janitrol Heater is located where?
Nose compartment
What is the max temperature for the Janitrol heater?
325 Degrees
What is a TOP PRIORITY when operating the Janitrol heater?
Must have sir flow over or thru the heater before turning it on. Either fan or the cooling vents open
Where is the Janitrol heater circuit breaker located?
In the front nose compartment (not accessible from the cockpit during flight).
How does the Janitrol heater provide it’s heat?
Gas fired (burner) using .5 gallon per hour from the right tank.
How do you know if the Janitrol heater has OVERHEATED?
Amber WARNING LIGHT comes on.
What kind of PROPs are on all of the Twin Cessnas?
Constant Speed, Varible Pitched, Full Feathering, Non-Reversing
Which aircraft has an Air Conditioner?
414
How does the A/C unit work on the 414?
Hydraulic Driven, Right Engine, restriction during T/O and Landing
How does the Emergency Field Switch Work?
When the Battery is dead, by activating this switch it will supply power that EXCITES the Alternators to produce charging output to the battery.
What kind of construction are the Twin Cessnas?
Semi Mono-coat Design
How many exits on the Twin Cessnas?
2
Where are the trim tabs located on the control surfaces?
Aileron - 1 tab on the left side, Elevator - 1 tab on the right side, Rudder - 1 tab
What are the differences in the flaps in the 3 aircraft?
All the same, “WORM GEAR DRIVEN”
414 has different numbers 15/30/45
414 has Split Flaps
What the differences in PRESSURIZATION in the 2 aircraft?
310 is NON-PRESSURIZED
414 is PRESSURIZED
How does a pilot operate the PRESSURIZATION SYSTEM on TakeOff and Landing?
Set PRESSURE DIFF to 1000’ ABOVE cruising altitude on climb and 500’ ABOVE field elevation on descent
What is the NORMAL Range for PRESSURIZATION DIFF?
0-5 PSI (max 5.3 PSI)
What is the process of Cooling the Turbo chargers?
Engine Oil
What is the cool down time for the TurboChargers?
3 minutes
What specific condition can occur inside the turbochargers if NOT ALLOWED to cool before shut down?
The oil in the turbo charger can boil, or COKING
What is the MAX allowable oil in each engine?
12 quarts
How many positions do the FUEL SELECTORS have on the 310? And what are they?
4 – Mains, AUX, CROSS FEED, OFF
How many positions do the FUEL SELECTORS have on the 414? And what are they?
3 – MAINS, CROSS FEED, OFF
There is also a SHUT OFF HANDLE
414 - Number of FUEL PUMPS
5 – 2-engine driven, 2-auxiliary electrical, 1 for the heater
414 - Where is the external power receptacle located?
In the left wing, aft of the nacelle fairing.
Is it permissible to reset a circuit breaker?
Yes, after a three minute cool down
414 - Why does this aircraft have 2 spare fuses?
One for each alternator field fuse
Where is the battery located?
Left wing stub
What is the minimum oil level for flight operations?
9 quarts
What equipment is required to be CERTIFIED “KNOWN ICE”?
Wing Boots (inboard and Outboard / Vertical and Horizontal Stabs), Heated Windshield, Stall and Pitot Heat, Prop Heat, Ice Wing Light
When you lose an engine on a TWIN ENGINE AIRCRAFT, how much performance is lost?
80%
How do the wing boots inflate and deflate?
Inflate from the exhaust side of the vacuum. It’s on a 6 cycle rotation…TAIL first then WINGS.
If you start one engine and BOTH RED VACUUM BUTTONS DISAPPEAR is the aircraft safe to fly?
NO.
IF both buttons suck in the one engine running that valve has failed which means if you lose an engine in flight you could lose vacuum pressure which means you could lose the ATTITUDE INDICATOR and the ability for your boots to functions.
The ALTITUDE at which the WASTEGATE is fully CLOSED?
Critical Altitude
What does the WASTEGATE do on the 414?
ON THE GROUND the compressor provides more air than the engine needs so it opens and dumps the air. As you climb and require more power the gate closes to allow more air into the engine.
On the 414 after the air is pressurized and cooled through the heat exchanger how does it enter the cockpit?
Through the environmental system (air conditioner, heat, or normal vents).
On the 414 there is an air inlet at the root of the inboard wing what does it do?
It allows air through a heat exchanger that cools the pressurized air for the cockpit
How does the cabin on the 414 obtain pressurization?
From the compressor on the turbo charger
When you land what safety features are in place to make sure the cabin is not pressurized?
The squat switch senses the weight on wheels and opens the dump valve.
What three ways can you test at the gear is down using the gear horn?
1) left throttle below 12” and gear not down
2) right throttle below 12” and gear not down
3) flaps beyond approach and gear not down
What are 6 things the squat switch ties to?
Activates/deactivates the landing gear switch
Opens/closes dump valve
Starts/stops Hobbs meter
Activates/deactivates gear lights (3 green no red)
Starts/stops landing gear motor
The gear horn
Explain how the props are ADJUSTED on a Constant Speed/Variable PITCH Prop?
Engine oil pushes the piston in the hub based on where the lever is in the cockpit. There are springs and nitrogen in the hub that stop the piston from going too far.
Explain how the props STAY at a CONSTANT SPEED on a Constant Speed/Variable PITCH Prop?
Their counter balances on each blade. As the rotation increases or decreases different from what is set in the cockpit the counterbalance Will adjust the pitch of the prop to keep the speed constant.
