Starting the engines |
A step-by-step procedure (from cold and dark aircraft). Complete checklist can be found from the electronic kneeboard. Pre-start check: Check that condition levers are on "Cut Off" position and that prop pitch levers are fully forward. Also check that parking brake is set, and power levers are in "Idle" position. Ensure that you've loaded a correct amount of fuel for your planned flight and that airplane is within weight limits. Check that cabin door has been closed and properly latched. 1. Turn on the battery master switch. 2. Switch on the rotating beacons. 3. Clik right engine start switch to "ON". 4. Monitor the gas generator RPM (Ng) reading and wait until it reaches 12%. 5. Move right condition lever from "Cut Off" to "Low Idle". If Ignition does not take place, the starter will automatically disengage in 25 seconds. 6. Monitor the engine ITT. Maximum allowable temperature during the start is 1000 degrees C. 7. Repeat the procedure for the other engine 8. Switch on both generator master switches, and check battery charge rate |
Taxi | Switch on the taxi light, release parking brake and advance the power levers slowly to start moving. You will need to make constant power adjustmens to control your speed. To help control your taxi speed, leave the condition levers to "Low Idle". |
Take-off | Check that flaps are set correctly (middle position or up) for take off, and that you have some positive elevator trim (around +4 degrees). Switch on landing lights and strobes when entering the runway. Advance condition levers to "High Idle". Advance power levers while monitoring the torque gauges. Keep them below 100%. Start pulling back on the yoke at around 110 knots and establis 10 degree climb attitude. Retract landing gear and flaps. Reduce some power, and pull back the prop levers for around 1600 RPM for climb. Switch off landing and taxi lights. |
Cruise |
Establish your cruise altitude (typically somewhere between 25000 to 30000 feet). Pull back the prop levers to 1500 RPM for normal cruise. Adjust the power levers to gain desired fuel economy and/or speed.
|
Descent | During descent, redcuce power as needed to fit your planned descent profile and to prevent aircraft from exceeding it's maximum speed limits. |
Landing | For landing, check gear down and locked and switch on landing and taxi lights. Select approach flaps as you bleed off speed. Fly the landing circuit at around 130 to 140 knots. On final, select full flaps, check that prop levers are fully forward and condition levers are at "High Idle". Maintain around 120-115 knots on final approach, slowing to around 100 knots when reaching the runway threshold. Don't pull the power all the way back to slow down. The flight idle limit is around 65% Ng. If you go below that, it will take longer for the engines to spool up in case you need to do a go-around. After landing, engage reverse thrust as necessary. Exit runway and select "Low Idle" for taxi back to the parking. |
