**********************************
Douglas DC-8 Super 71F
 Version 4 for FS2002
Historic Jetliners Group
January 2002
**********************************

This model is for FS2002 only.

This is a pretty good model of the DC-8-71 series!
There is a good description of the DC-8 series at www.boeing.com.
The -70 series DC-8's were all modifications of existing -60 series airframes, by replacing the old P&W JT3D engines with newer CFM 56-2 engines. These airplanes are Stage 3 compliant! So the -71 is basically an upgrade of the -61 model. The -61 model is basically an earlier -50 series with two fuselage extensions totalling an additional 36 feet!
With a range of about 4000 miles, and able to carry up to 18 standard cargo containers, the DC-8-71F makes an excellent air freighter.

FS2002 Considerations
This airplane uses a true FS2002 flight model by Michael Verlin. Its recommended that you use our new FS2002 DC-8 panels. They can be downloaded for free at our website.

The model comes setup to use the default 737-400 sound system. This is okay, but for a better sound experience, try out our custom -70 series sound package by Aaron Swindle. A free package available at our website.

Flying the DC-8
We are still learning to fly the DC-8 ourselves! Its a big airplane and the CFM engines produce a lot of power. Planning is everything with this airplane. You must stay ahead of it!
The landing gear has a very long wheel base and a narrow wheel track. Ground handling isn't to difficult though if you plan ahead. In tight areas, slow down!
At MTOW, set the flaps to 15 degrees and increase the power to 100% N1. Expect the airplane to roll about 8000 to 9000 ft before reaching Vr (about 145 kts). DO NOT PULL THE NOSE UP STEEPLY. You'll hit the tail! At V2 and positive rate of climb, gear up and look for a target speed of about 180 kts and climb 2200 ft/min. As you clean up the flaps during your climb, the airspeed will increase quickly. You will have to reduce power quite a lot to keep from breaking the 250 kt speed limit below 10,000 ft. Power managment is a full time job with the DC-8.
It hand flys quite nice, but autopilot operation is preferred above 10,000 ft and 250 kts.
Plan well ahead for your descent! Reduce power to flight-idle and start trimming the nose up to bleed the speed down to 250 kts indicated. Drop in 1 notch of flaps, then start your descent. Monitor power and airspeed closely. Maintain 250 kts down to 10,000 ft. If you get into airspeed trouble, use the landing gear to slow down! Use of the spoilers in flight is NOT APPROVED! If you cheat the spoiler system, you'll get into trouble just like some real life DC-8 crews did.
Approach (Vref) with full flaps, spoilers "ARM" and 146 kts max (143 best). This model will fly a coupled approach very nicely down to CAT 2 minimums, but you must monitor and adjust the power closely! The airplane should hold a nose down attitude during approach. Pull the power levers all the way back to the flight idle gate as you over fly the fence and start trimming the nose level. DO NOT HOLD A NOSE HIGH ATTITUDE. You'll scrape the tail! Hold her level and let her settle in. After all 3 gear are firmly on the ground, reverse thrust and brakes. The spoilers should automatically deploy on main gear touchdown. The QEC reverser shells will open when you pull the throttles all the way to the flight idle gate and hold the F2 key. Expect the landing roll to be about 6000 to 7000 ft. This is not an airplane for small airports!

Misc operating notes:
1. The engine reversers work with the spoilers.
   This is a temporary fix until we can figure out how
   to get the throttle activated reversers to work in
   FS2002.
2. The inboard ailerons function at all speeds.
   The outboard ailerons function only after the first 
   notch of flaps are lowered.
3. The cargo door is tagged to the #1 engine. 
   The #1 engine must spool down to zero before the door 
   will open and interior becomes visable. The door closes 
   after the engine is restarted.
