Terminals CONNECTED
External power plug INSERT IN FUSELAGE
start normally
turn off right engine
disconnect external power
restart right engine
operate at low rpm
```
40

- fuel selectors OFF
- mixtures ICO
- Extinguish fire
41

- mixture ICO
- cowl flap OPEN
- Land immediately
42

Non essential electrics OFF
cabin heat/fan OFF
Extinguish
Open fresh air vents
43

Vtoss
68kts
47
Single engine service ceiling
When climb rate can't achieve more than 50fpm
48
Seminole single engine climb performance ISA day
160fpm
49
What is the decision speed
The point where gear is taken up as there is no more remaining runway available to land in an emergency. 88kts
50
What is one of the best indications of a failed engine when under the hood
EGT will drop
51
What is the max speed for the autopilot
185kts
52
What is the oil pressure range
15-115 psi
53
What is the gyro suction range
4.5-5.2
54
what is the CHT range?
200-500
55
What is asymmetric fuel consumption
60L
56
Oil pressure send prop to fine or course pitch?
fine
57
In the event of oil pressure loss, will the prop go fine or coarse
coarse
58
Describe the CSU
pitch levers are really a 'request lever'. You set an rpm, and the CSU will try and maintain that rpm. If the manifold pressure is not enough, then it won't be able to hold that rpm.
59
When considering to fix the prop instead of feather, what process is involved?
```
CCFMOST
Carby heat
Cowl flaps
Fuel selector, quantity, pump
Oil Ts and Ps
Throttles
```
60
What do we need to consider when we feather an enginr
```
SELFDR
Secure engine
Electrical load reduced
LSA (ac can't hold certain altitudes with one engine)
Fuel
Diversion
Radios
```
61
what is Va
Va is the speed at which an aircraft will stall before structural damage will occur during turbulent conditions or during rapid control surface deflection.
62
how do we alleviate the static vent of water
Water dump switch front left panel
63
Where does nitrogen pressure send the prop?
towards coarse
64
In the event of a loss of nitrogen pressure, where would the props move
towards fine
65
how many seconds does it take for a prop to feather
6 seconds approx
66
what can make the gear lights difficult to see sometimes?
When the nav lights are on during the day the gear lights dim, and it can be difficult to see, so turn them off to make sure that this doesn't happen.
67
where is the hydraulic pump located?
In the baggage compartment underneath a panel
68
what degree of turn can the nose wheel achieve
30 degree
69
what is the turning radius of the ac
33ft
70
how much rpm is required to maintain full 60amps
2000rpm
71
What instruments are powered by the vacuum pumo
AH and DG
72
where is the emergency exit
left hand window
73
How do you operate the emergency exit?
remove left vertical thermoplastic panel, and pull the lever. The window will fall free from the fuselage.
74
Why are there two different stall warning detectors?
the inboard detector is used when flaps 25 or 40 are set, and the outboard is used for all other settings.
75
Can you test the stall warnings on the ground?
nope, squat switch inhibits it
76
wingspan?
38'6.6"
77
length
just under 28'
78
min oil pressure for idling?
25
79
min oil pressure for cruise?
55
80
grade of oil?
20w50 or 15w50 (ashless dispersant)
81
oil psi range? (normal?)
25-115 (55-95)
82
min and max fuel pressure?
0.5-8psi
83
does the seminole have a critical engine?
No, the left rotates clockwise (as viewed from the cockpit), and the right rotates anti-clockwise, and so they both have the same effect in terms of engine failure.
84
Describe coarse and fine pitch
Fine pitch allows a higher rpm to be used, and thus allows more power to be generated, especially at low speeds. The downside to this is that greater drag is caused.
Coarse pitch is used for cruise because the lower rpm setting means less fuel consumption and less drag, which improves fuel efficiency and range.
