Training Manual for Cessna 208 Caravan

- If Inlet Anti-Ice annunciator does not turn on, verify that the anti-ice system is operational by looking for associated drop in EGT or engine torque. -If system does not work, turn on ignition and exit icing conditions as soon as possible. ATI-ICE-ADD, Issue 4, November 19, 2012 15 • Emergency Procedures Propeller Anti-Ice System Malfunction - Propeller Anti-Ice Ammeter should indicate 24-28 amps continuously in AUTO. -If you need to use MANUAL mode, cycle it ON and OFF every 34 seconds to avoid runback issues. - MANUAL mode only activates the inboard boots on the propeller blades. ATI-ICE-ADD, Issue 4, November 19, 2012 16 8 00 Emergency Procedures Airspeeds (208B only) - Maintain a minimum of 125 KIAS in level flight in icing conditions with flaps up. - Maintain a minimum of 115 KIAS during climb to exit icing conditions with flaps up. ATI-ICE-ADD, Issue 4, November 19, 2012 Changes to Normal Procedures • The abbreviated pilot checklist from Cessna's icing supplement S-1 is included in AFMS section 9-1-4, modified as needed for the engine installation. • Same general procedure changes for the Emergency Procedures are relevant for the Normal Procedures. ATI-ICE-ADD, Issue 4, November 19, 2012 17 18 9 Changes to Normal Procedures • All references to the inertial separator have been removed. • All instances requiring activation of the propeller de-ice system are preceded by activation of the ignition and engine inlet anti-ice systems. • The ignition and engine inlet anti-ice systems must be turned ON whenever visible moisture is present and the OAT is below approximately 5°C (40°F). ATI-ICE-ADD, Issue 4, November 19, 2012 19 Changes to Normal Procedures • All instances requiring 1900 RPM have been replaced by setting the engine speed control to MAX. ITT limitations of the PT6 have been replaced by 650°C EGT limitation for the TPE331. • For the 208B, the minimum speed in icing with flaps up is increased to 125 KIAS, and the minimum exit climb speed is increased to 115 KIAS with flaps up. ATI-ICE-ADD, Issue 4, November 19, 2012 20 10 Performance Differences • Stall Speeds - Stall speeds increased with higher gross weight. - Ice accumulation may result in a 20 KIAS increase in stall speed. - Aircraft may stall without warning. Do not rely on buffet or aural stall warning. - Maintain at least 115 KIAS with flaps up while in icing conditions. (208B only) ATI-ICE-ADD, Issue 4, November 19, 2012 Performance Differences • Enroute Tool for Exiting Icing - - - New enroute tool is included in Aero Twin AFMS Section 9-1-5. - New enroute tool expands Cessna's enroute tool to include weights up to 9,062 pounds for the 208B and 8,360 for the 208. New enroute tool does not raise the icing service ceiling for any lower weight. ATI-ICE-ADD, Issue 4, November 19, 2012 21 22 11 Performance Differences • Cruise Performance New cruise performance chart added to Aero Twin AFMS section 9-1-5. - New chart replaces PT6 power settings with those for TPE331 engine. - New chart provides data for increased weights. ATI-ICE-ADD, Issue 4, November 19, 2012 Performance Differences • Landing Performance – Minimum flaps UP speed increased to 115 KIAS for the 208B. ATI-ICE-ADD, Issue 4, November 19, 2012 23 24 12 Summary • Aero Twin training is required by FAA. Engine conversion allows flight in icing at higher gross weights. • Stall speeds are increased with higher gross weight, which requires an increase in the minimum icing airspeed with flaps up for the 208B. • New procedures inherent with change in engine operation. • Increase in power does not exempt the aircraft from the laws of physics. Do not fly in freezing rain, freezing drizzle, mixed, or severe icing conditions. ATI-ICE-ADD, Issue 4, November 19, 2012 25 Evaluation Complete evaluation and return to Aero Twin to receive certificate of completion for this training. If you have any questions, contact Aero Twin Engineering at (907)274-6166, or jkepler@aerotwin.com. ATI-ICE-ADD, Issue 4, November 19, 2012 26 13 CTURING MANUFA MAINTENANCE NCE SALES EST. 1975 AERO TWIN, INC. The following is an evaluation to be completed following the review of Aero Twin training document ATI-ICE-ADD and the Flight in Known Icing section 9-1 of Airplane Flight Manual Supplement 850- AFMS or 950-AFMS. The FAA requires review of that material within the 12 calendar months prior to flying the Cessna 208 or 208B equipped with Aero Twin's Honeywell engine modification, when flying into known or forecast icing conditions. The FAA also requires Aero Twin to track those pilot who have completed this review. To enable Aero Twin to do this, once you have completed this evaluation form, send it, along with proof of completion for the required Cessna cold weather ops training, to Aero Twin using the address or fax number below, or email it to jkepler@aerotwin.com. A certificate of completion will be sent to you for your records. Name: Date: Pilot's Certificate No.: Company (if applicable): Address: Phone: Fax: Email: 1. Describe the Propeller De-Ice cycle: 2. Which parts of the Propeller De-Ice Boots are activated when the switch is in MANUAL? 3. In the proper order of activation, what must be turned on when entering visible moisture when OAT is less than +4°C (40°F)? 4. Icing conditions must be exited immediately when level flight cannot be maintained at what airspeed? 5. What are the minimum allowable speeds in icing with flaps up for level flight and for climbing for the modified 208B? 6. If the Engine Inlet Anti-Ice annunciator does not illuminate, how can you tell if the system is working properly? 7. You are travelling on a route through forecast icing with a MEA of 12,000 feet. The aircraft weight is 8,000 pounds and the OAT is -10°C. What area of the Enroute Tool for Exiting Icing are you operating in, and what are the consequences of operating in that area? 2403 Merrill Field Drive • Anchorage, Alaska 99501 • (907) 274-6166 • Fax # (907) 274-4285 • FAA Certified Repair Station FE-4R177M • ~Dedicated to serving the aviation industry since 1975~
