| Question | Answer |
|---|---|
| Percentage TRQ AEO max takeoff power | 78% |
| Percentage TRQ OEI max continuous power | 89,5% |
| Percentage TRQ Transient dot | 82% |
| Percentage RPM activating LOW RPM WARNING (pulsed tone) | <95% |
| Percentage RPM activating HIGH RPM WARNING (gong) | >106% |
| Percentage RPM activating flashing ROTOR RPM warning and continuous tone. (can not be switched off) | >112% |
| At what temperature is the BAT TEMP warning acivated | 70 C |
| With an engaged rotorbrake and a stilstanding rotor, is the caution ROTOR BRK on? | No it has to come on the moment the rotor starts turning. |
| The main transmission is attached to the airframe by ..... (7 points) | 4 ARIS (Anti Resonance Isolation System) dampers, 1 Side Load Strut (Y-strut) 2 Torque struts |
| In case of a torque strut failure, what keeps the gearbox in position and prevents a total failure of the ARIS mounts? | The emergency stop. |
| When testing hydraulic systems pedal forces will increase when testing system.... | 1 |
| How much hydraulic fluid must be visible in the sight glass? | It must be at least half full |
| If hydraulic system 1 fails, which SAS will be inoperative? | P&R |
| Yaw SAS is controlled by .... and actuated by ... | The FOG (fiber optical gyro) - Yaw actuator (SEMA) |
| Why is the Vne OEI 110 kts? | Because the autorotational Vne is 90 kts. The difference can't be to be big in case of an engine failure. |
| How much dry operating time do the transferpumps have? | 20 min |
| Enroute daling vereisten: - minimale vlieghoogte - positie - verkeer - communicatie - daling benen MSA gecontrolleerd? - VMC weersomstandigheden - radalts | - 1000 ft hoogste hindernis bin 5nm / VMC omst en min 3 km vizz. - geconformeerd voor daling dmv VOR en Gps -geen conflict verkeer - ATC geinfond evt klaring - daling bij voorkeur gecontrld - vmc voor vfr klassr airspace - beide rad alts werkend. |
| In which supplytank is a foam core intergrated and how much does it reduce the fuel quantity? which results in a difference of how many minutes before completely dry. | RH - 4kg - 1-2 minutes |
| what's technically the difference between the transfer pumps and the prime pumps? | Nothing, except that the transfer pumps have a check valve and the prime pums don't. |
| what is the maximum rate flow for refuelling? | 100L / minute |
| When no fire warning is evident and the EMER OFF SW is pushed, what will happen? | Only the shut-off valve will close. |
| At what amount of kg's is the LOW indicitation (warning) triggered due to a shortage in the supplytanks? | 28kg |
| Why is the maximum indicated amount in the main tank 448 kg, while the nominal max quantity is 452 kg? | 4 kg can not be displayed because for crash safety the fuel sensors must not contact the fuel cell ceiling. |
| FUEL QTY FAIL caution indicates? | One supply tank sensor or both main tank sensors fail. |
| FUEL QTY DEGR caution indicates? | |
| What is the max gross mass?? | 2910 kg |
| What kind of main rotor system does the EC 135 have? | A bearingless main rotor |
| What's the Vne of the EC135? | 160 kts |
| What's the Vne OEI? | 110 kts |
| What's the Vne for a autorotation? | 90 kts |
