DC-9 Model 51 Performance Information Preface This is my second attempt at a realistic Flight Model, having been inspired by the popularity of my DC9-31, and my first attempt at designing with flight shop. Using the flight dynamics editor, I have made this aircraft behave as described in the flight manual. So you are aware, I am an Engineer, and an Ex Pilot. I have flown DC-9, 727, and one of these days, the 747 simulators. Thanks to the defunct airline, whose manual contributed all the specs and operating procedures. The Eastern livery is in its' memory, since the egomaniacs that ran the union and the management could not see fit to keep a pioneer in the air. I apologize for the paint job, but art is not my strongest subject. Feel free and drop me a line with your comments, questions or criticisms. I do read and respond to all mail.

DO NOT CHASE THE AIRSPEED. Note: Below 10,000Ft at Max landing Weight or less, 250KIAS is applicable. Maximum Operating Altitude, 35,000Ft Normal Operations, Description: NOTE: IF you have full tanks, you must burn off at least 1,000Lbs of fuel prior to takeoff. The aircarft is not certified for flight above gross weights of 121,000Lbs. 1. TakeOff thrust must not exceed 5 minutes total time. 2. Normal TakeOff, set flaps at 5deg or 25deg depending on fuel/passenger load, length of runway. 3. Apply thrust to accelerate, maintain below 70% N2. When airspeed exceeds 40 - 60 Kts, apply takeoff thrust. 4. At Vr, rotate smoothly to takeoff attitude (5 - 10 deg nose up). Confirm positive rate of climb at takeoff. 5. At 35Ft AFL (Above Field Level), speed should be at V2 to V2 + 10Kts, climb to 1000 AFL at V2 + 10Kts, 20Deg pitch, raise gear. 6. At 1000 AFL, reduce pitch attitude by not more than 1/2 (one half) the angle required for V2 + 10Kts to reach 1000 AFL. Set climb thrust (normally 95% N2. Maintain climb gradient while accelerating. Retract Flaps/Slats on schedule. 7. Continue acceleration to Vzf (Zero Flaps)speed. If Vzf is reached before 3000Ft, climb at Vzf to 3000Ft. 8. 3000Ft AFL, accelerate to 250Kts, maintain 500-1000 ft/mn rate of climb during acceleration. Climb at 250Kts to 10,000Ft. 9. Accelerate to climb schedule (290KIAS) past 10,000Ft to cruising altitude. Maintain speed until cruise altitude is reached. Vzf Schedule: Flaps Retract V2+25 (5Deg T.O. Flaps) V2+35 (15Deg T.O Flaps) Cruise power is 85% N2 (FAN indicator) Descent in Range (to landing) 1. Start Descent at XXX DME. Target descent rate is 500 Ft/mn to reach assigned level. To determine XXX, use the following formula (Altitude (in 1,000's) X 3 = DME distance to start descent) Example 1 Cruise altitude 31,000 DME transmitter on field 31 (000) X 3 === Start Dexcent at 93 Miles DME Cruise Altitude 31,000 Airport 10 Miles beyond DME transmitter From Example 1 93 Miles DME Airport Beyond Transmitter -10 Miles ======== Start Descent at 83 Miles DME 2. 50 miles from the outer marker, level off at 10,000ft and decelerate to 250KIAS. 3. Descend at 250KIAS 40 miles from outer marker. 4. Set 5 Deg Flaps on entering IAP (initial approach point). Speed set at 160KIAS. Descend to MDA (minimum Descent altitude) 5. At localizer capture, drop gear, final check list. 6. At Glideslope + 1 dot, set 25Deg Flap, Speed Vref + 50Kts 7. At Glideslope capture, Full Flaps, follow glideslope. Maintain Vref on final. 8. Land. 9. After landing, retract flaps, taxi to terminal. Exclusion and legal The author takes no responsibility for the operation of the aircraft. No warranty as to the fitness or merchantability is expressed or implied. Other Model Limitations: 1. The DC9-51 has 3 tanks plus an Aux tank. I took the aux tank quantity and added it to the main tank. Flight Sim only supports 4 fuel tanks. 2. Fuel consumption is not realistic. Real jets consume about 8,000Lbs/Hr per engine at takeoff, between 3,000lbs and 5,500 Lbs/hr per engine at cruise. This is a know bug with Flight Shop. By flying at 85% FAN, your fuel consumption will be close to real. 3. I wish BAO made the landing lights work 4. The published manual list EPR settings for takeoff, climb and cruise. Since there are no EPR gauges in FS5, I tried to convert to % RPM as best as possible. 5. Flight sim only gives you 4 notches of Flaps, and no slat only setting. The airplane will display slats and flaps at the same time. Wish List Any panel designer out there want to work with me on a realistic panel? EPR Gauges Flight director bars for the Attitude indicator. Radar (would be nice) APU for starting the engines
