TC’s practical “logical scan” B47 start-up procedure to suit the turbo charged B47 and Kawasaki KH4:

Seated in the Cockpit: seat belt(s) secure, relaxed, ready to start

Loosen frictions – check all controls full and free.  Don’t only move the cyclic in a circular motion – move it full forward and then full rear followed by full left and then full right. This gives you a “feel” of each servo’s travel in each direction.

Re Tighten all frictions. Take care not to over-tighten the collective friction as you may easily strip the thread on the friction retaining nut.

Fuel valve – on.

Mixture  - full rich.

CARB heat - cold.

Circuit breakers - in (include starter – check boost pump. Leave landing lamp off for day VFR)

Master switch and generator switch - on.

Magneto switch: check - off.

Check all gauges for normality.  R.P.M. on zero (both needles together) other gauges as required (check temps against OAT if 1^st start of day)

Check Main Rotor blades are untied and @ 11 o’clock position

Recheck harness, headset, doors, passenger

Call “clear to start?”  (do not prime if hot engine)

1^st start of day – cold engine - lift collective fully up - open throttle fully and shut – 3 times – then:

Collective down – throttle fully closed. This stops you getting a quick start and burning your clutch or breaking the top piston rings due to thermal shock if the throttle cam box is worn or rigged wrong

Push start button – count 3 compressions – then:

Turn magneto switch to "both".

As engine starts, check that the oil pressure is rising thru 30 Psi – engine revs maintain 1700 – check rotor revs climbing.

As the main rotor revs hit 1500, close the throttle – marry the tacho needles and maintain 1750 ERPM until the cylinder head temp goes through 50 degrees (about 90 seconds with a cold engine).  Then slowly bring ERPM up to 2400 normal idle to ensure positive clutch engagement and turbo spinning.

Avionics - on.

Warm up is a minimum of 5 minutes from engine start at any start engine temperature to stabilise turbo operating temp.

After min 5 Minutes warm up  - Slowly take ERPM. to 3100

System integrity checks after the 5 minutes engine warm up from engine start: Use the following method to ensure engine & transmission o.k. (lubed plus warm) before take off:

          (Touch all gauges with a finger to confirm what your eyes are seeing)

Check tacho needles for clutch slip.

Check mags Left & Right then back to Both. Do NOT switch to Off  at this RPM for any reason except an emergency stop!

Check M.A.P. for flat pitch figure. (see This Web Site – Safety Publications  - TC’s Papers)

Check oil pressure in the green.

Check fuel pressure.

Check engine and transmission oil temps.

Turn hydraulics off – motor power cylinders fore and aft, left and right etc.  (Same as G5 – check each cylinder operation both ways rather than stir stick!)

Slowly close the throttle to check that the Sprague clutch is working as indicated by a tacho needle split. Snapping the throttle shut can be detrimental to the crankshaft

Idle at 2400 ERPM – then pre take off checks. Remember to put Hydraulics ON

Engine Stop procedure: (at any time except emergencies)

Idle for 5 mins (MIN) to reduce oil temps and turbo core temps

Smoothly roll the throttle fully shut

Safe flying
