and pressure 3 Start button Push 30 seconds after switching boost pumps on, and keep running through start sequence (up to 40%). Minimum voltage drop is to 15v. If it falls below, abort, as you may not get a light-up. If you do abort a start, close the fuel flow, and switch off the fuel pump and generator. If it was due to high T4, check battery voltage. If normal, crank the engine for 15 seconds and try again, increasing fuel flow gradually. 4 Fuel flow Move forward about a third when NG reaches 10% (if OAT is below zero, do this as
Start button is depressed).
5 NG  Increasing

6 T4  Control with fuel flow – keep around 700 degs.
7 Rotors  Turning

8 Start button  Release between 40-45% NG
9 Oil pressure  Rising

10 Fuel flow  Accelerate smoothly to 68%-ish – do not allow NR to remain steady between 300-320 RPM. Maintain until indication on oil temp gauge.

23 Hydraulic Test: Lock collective, actuate test button to cut off pressure, HYD light should come accumulator on, and horn should sound. Move cyclic 2-3 times along both axes for 10% of total travel, there should be no control load. Press the test pushbutton to restore hydraulics. Horn should cancel and HYD light should go out.
24 Hydraulic Check isolation. Actuate switch on collective – HYD light should illuminate and you pressure should feel control loads immediately, except on pedals. Restore pressure with switch – the horn will sound till the light goes out.

2 Temperatures  Stabilised over 30-second rundown period at flight idle or with NG at 70%, which is the most efficient gas generator speed for cool down. It used to be 3 minutes at 67% NG, but Turbomeca now recommend 30 seconds, as a 2-minute rundown only reduces the temperature by 20 degs C anyway, which just increases fuel consumption with no visible effect on coking up. Temperature in the bearings initially goes down, but after 30 secs it goes all over the place, due to low oil flow at idle. It is better to run back up to Flight Idle for a bit before shutting down.
