C90B Checklist

 PRESTART

1. All switches OFF

2. Rudder Boost and Electric Trim toggle switches - ON

2. Pressurization SET to 1,000 feet above your planned cruise altitude

3. Altitude preselector SET to your first assigned altitude in your clearance



START

1. Parking Brake - SET

2. Props - FWD

3. Bleed Air - OPEN (helps prevent hot starts, and bleed air is used for pressurization)

4. Boost Pumps - ON (Boost pumps prevent cavitation in the engine driven fuel pumps and must be on anytime the engines are running or N1 is above 10%)

5. Battery – ON

6. Beacon -ON

7. R Start/Ignition- ON (switch UP, if you put the switch DOWN it just motors the engine without the igniters)

8. Watch for oil pressure and N1 to begin to rise, R IGN annunciator illuminated

9. When N1 stable above 12%, R Condition Lever LOW IDLE

10. Monitor ITT and N1. When N1 above 51%, R Start Switch OFF

11. R Condition Lever - HI IDLE

12. R Gen Switch up to RESET, HOLD it on one to two seconds, then RELEASE. Switch will drop to ON

13. Verify R GEN annunciator extinguished, monitor R Gen Load on overhead gauge. When below 50% (it’s always at 40% on my sim), reset the caution and warning lights and repeat 7 through 13 for left engine.



AFTER START

1. Condition Levers - LOW IDLE

2. Transfer Pumps – AUTO

3. Boost Pumps – VERIFY ON

4. Crossfeed – AUTO

5. Inverter - 1 or 2 (we alternate which one used for each flight)

6. EFIS Power – ON (switch on center pedestal)

7. EFIS Aux Power – ON (tiny toggle switch on left side of the Captain’s panel)

8. Avionics Master – ON

9. Altimeters – SET

10. Annunciator Lights – TEST, then RESET the WARNING and CAUTION lights by pushing (clicking) them

11. Engine Anti-ice - ON (this sets up electrically actuated vanes inside the intake duct which inertially separates ice, pebbles or any other debris and directs the debris out through  openings in the bottom of the cowls)

12. Transponder – SET and on ALT (altitude)

13. Instrument Vacuum/Pressure – CHECK (gauges are on the far right panel)

14. Flight Controls – FREE & CORRECT

15. Park Brake – RELEASE



BEFORE TAKEOFF

1. Auto Ignition – ARMED (auto ignition turns on the igniters any time the torque is below 400 lbs, so should not be turned on until just before takeoff to keep the igniters from wearing out prematurely)

2. Engine Anti-Ice - OFF or AS REQUIRED (reduces takeoff power a little so OFF if conditions allow)

3. Autofeather – ARMED

4. Trims – SET (Elevator 3 degrees UP, Rudder and Aileron set to 0)

5. Flaps – UP (flaps are always up for takeoff with this airplane)

6. Takeoff Brief – COMPLETE (brief the assigned heading and altitude, set the OBS and Heading Bug as required, and discuss what you’ll do in an emergency before and after rotation)

7. Lights and Strobes – ON

8. Anti-ice/Hot 5 - As Required/ON (This is not the engine anti-ice. This is the windshield heat and prop deice, both which should only be on if necessary, and the Hot 5 [Stall Warning heater, L & R Pitot Heat, and L & R Fuel Vent Heat] which should always be on in flight no matter how nice the weather).

9. Condition Levers – HIGH IDLE



TAKEOFF

1. Power Set – 1,200 ft-lbs torque normal, 1315 ft-lbs (make sure ITT is below redline) for max performance

2. Call out 80 KIAS (below 80, abort on the runway if any caution or warning annunciator lights illuminate. From 80 to 95, abort only if a red warning light, above 95, you're going flying unless something really catastrophic happens)

3. Rotate at 95 KIAS

4. Establish climb  Vy 112;  Vx 101  Vyse 108



AFTER TAKEOFF

1. Positive rate of climb – GEAR UP

2. At 1,000 feet AGL, lower the nose a bit to accelerate to 140-150 KIAS, reduce power to 1,100 ft-lbs torque, pull props back to 2,000 RPM, and put power back to 1,200 ft-lbs or just below ITT redline. Cruise climb at 150 KIAS.

3. Yaw Damper – ON

4. Prop Sync - ON

5. Gear - CHECK (no red lights inside the gear handle nor green lights by the handle)

6. Verify Pressurization - SET

7. Recognition Lights - OFF above 10,000 feet



CRUISE

1. Cruise Power/ Props SET (we set cruise power by adjusting the power levers for 250 lbs per hour fuel flow, and props to 1,900 RPM)

2. Autofeather – OFF

3. Pressurization – CHECK that it’s working by comparing the cabin altimeter in front of the throttles with the pressurization controller setting.



DESCENT/APPROACH

1. Altimeters – SET

2. Pressurization – SET (to 500 feet above the field elevation of your destination airport)

3. Autofeather – ARMED

4. Approach Brief – COMPLETE

5. Recognition Lights - ON below 10,000 feet



LANDING

1. Gear – DOWN, 3 green, no red lights

2. Landing Lights – ON

3. Prop Sync - OFF

4. Flaps – APPROACH  (Vapproach is 120 KIAS)

5. Yaw Damper – OFF

6. Full Flaps – AS REQUIRED

Note: If reverse pitch is used after landing, power levers must be set back to Beta or Idle before no slower than 40 kts to prevent propeller damage from runway debris.



AFTER LANDING

1. Auto Ignition – OFF

2. Engine Anti-ice – ON

3, Autofeather – OFF

4. Hot 5 – OFF

5. Recog Lights - OFF

6. Flaps – UP

7. Trims – SET for next takeoff , 3 degrees nose up
