AlphaSim B-1B Lancer Procedures
(Please see the Reference for explanations of the panel functions. Read the .pdf document "b1b-factbook" for more information on the actual aircraft.)
For performance and aircraft specifications see the aircraft menu.
Advanced/Simple Flight Models
This aircraft comes with a simplified flight model which limits the total aircraft weight to approximately 220,000 pounds by reducing the total amount of fuel available. It also is configured to have electric power always available. An advanced flight model is available in the "advanced" folder which enables a full fuel load and allows for electrical failures. Copy the file named "aircraft.cfg" from the "advanced" folder into the main aircraft folder entitled "Alpha B-1B Lancer", overwriting the existing "aircraft.cfg" file, to enable the advanced flight model. With the advanced flight model, the electric power will drain very quickly if the engines are off or the generators are shut down. The aircraft will also be very heavy so keep this in mind during takeoffs; the rotation speed is about 160 KIAS with a full fuel load.
Wing Flaps and Variable Sweep Wings
The wing flaps and variable-sweep wings are animated by the flaps switch. There are six positions in all. The first four flaps positions move the variable-sweep wings to the four positions approved for flight maneuvers. The positions are as follows:
Wing positions will be inhibited by aircraft speed at full realism settings.
Engine Start
Use Ctrl-E (autostart) to start the aircraft, or:
Takeoff (210,000 lbs.)
Climb
Use autopilot/autothrottle to set climb parameters as indicated in the table.Climb Control Chart (Normal Climb)
Speed | Wing Sweep | Feet per minute | Altitude |
250 KIAS | 15 degrees | 1800 | Below 10,000 MSL |
325 KIAS | 25 degrees | 3500 | Above 10,000 MSL |
A climb following the above chart to 30,000 feet will take about 13 minutes, use about 6500 pounds of fuel, and cover about 75 nautical miles.
Cruising
Wing positions will be inhibited by aircraft speed at full realism settings.
Altitude | Airspeed | Fuel Consumption | Naut. miles/1000 lbs |
30,000 feet | 0.8 Mach | 8570 pounds/hour | 55 |
30,000 feet | 1.05 Mach | 11700 pounds/hour | 53 |
