|
|
Which components make up the DC Generation system for the DA42? |
- Alternators - Alternator current sensor - voltage regulators - Alternator excitation battery |
|
|
What voltage (V) and Amp (A) rating are the alternator installations? |
28 v DC 60 Amp max. |
|
|
What voltage (V) and Amp (A) rating are the alternator installations? |
28 v DC 60 Amp max. |
|
|
Where are the alternators installed in the engines? |
Bottom left of each engine. |
|
|
What is the ACU? What does it do? |
- Alternator Control Unit. - It measures alternator output voltage. CAS message: “L/R ALTN FAIL” |
|
|
What is the voltage and amp hour rating of the main battery? |
24 v, 10 amp/hr. Lead acid battery. |
|
|
What is the main battery connected to? |
Hot battery bus, battery relay, and main aircraft ground. |
|
|
What is the voltage and Ah rating of an alternator excitation battery? |
24 v, 1.3 Ah |
|
|
What is the voltage and Ah rating of an alternator excitation battery? |
24 v, 1.3 Ah |
|
|
What is the main purpose of the Alternator Excitation Battery? |
The excitation battery will sustain the alternator output for emergencies if the field voltage fails. Once the alternator is running, they become self sustaining and recharge the batteries. |
|
|
Emergency power |
Emergency battery pack. - 10 non-rechargeable dry lithium manganese batteries - 3v, 1300 Ah - runs aircraft lighting and flood light for at least 1.5 hrs. |
|
|
What type of engines are in the DA42? |
- 2 Thielert Diesel Engines (TAE 125 - 01) - liquid - cooled, 4 cylinder, 4 stroke in- line turbo-charged engine. |
|
|
What is the horsepower and RPM setting at ISA? |
135 HP @ 2300 RPM ISA |
|
|
What are six characteristics of the DA 42 engine? |
1. 4 cylinders 2. 4 stroke 3. Liquid cooled 4. Turbocharged 5. Reduction gear to propeller 6. Wet sump oil system |
|
|
What is the difference between Diesel engines and gasoline engines? |
Diesel engines are quality controlled, gasoline engines are quantity controlled. Diesel engines do not have ignition systems and are typically turbocharged to ensure proper combustion. |
|
|
What is the maximum over speed rpm? |
2500 rpm |
|
|
What is the maximum over speed rpm? |
2500 rpm |

|
|
How many computers do the ECU’s have? |
Two independent computers, either of which can provide all control functions for the engine and propeller. - A is normal, B is backup |
|
|
What are the ECU’s controlled by? |
FADEC (Full Authority Digital Engine Control). |
|
|
What are the ECU’s connected to and how are they connected? |
They are connected to the engine, power lever and annunciation panel via an electrical harness. |
|
|
What powers the ECU’s? |
The alternator supplies power for the system, if the alternator fails, the battery provides power. |
|
|
Where are the ECU’s located? |
In the bottom of the engine nacelles. |
|
|
Where does the defrost lever provide heat from? |
The left engine. |
|
|
Where does the defrost lever provide heat from? |
The left engine. |
|
|
Where does the cabin heat lever provide heat from? |
The right engine. |
|
|
Where is the ventilation Duct located? |
On the lower surface of the right wing, (centre section). |
|
|
How many fuel tanks are there in one wing? |
- Inboard Chamber (with fuel level sensor) - Middle Chamber - Outboard Chamber (with fuel level sensor) |
|
|
What happens to the fuel probes as fuel levels decrease? |
The area the fuel probes are “wetted” with fuel decreases. They will not read accurately between 17 and 22 USG. |
|
|
Fuel low-level sensors: |
Float type switches installed on inboard end of each inboard fuel chamber. |
|
|
What effect does increasing oil pressure have on propeller pitch? |
A decrease of pitch and a higher rpm. |
|
|
What is the pressure accumulator? |
Nitrogen filled accumulator that is filled with oil at 290 psi when engine is running. It maintains oil pressure to the prop as pressure drops from deceleration or moves it beyond the start lock position if pressure is lost to that end. |
|
|
Endurance of anti-ice fluid: - Normal mode - High mode - Max mode |
