A guidance system guides a driver to drive a service vehicle, such as a baggage loading vehicle, into a prescribed parking position adjacent to an aircraft without colliding with the aircraft. The guidance system includes at least two indicator markers, preferably marker lights, arranged spaced apart from one another on the aircraft. The two markers present a prescribed visual pattern, e.g. an alignment of the two markers, along a line of sight defining a safe approach path. If the driver steers along this safe approach path so that he sees the prescribed visual pattern of the markers, then a collision between the vehicle and the aircraft will be avoided. Alternatively, a projector projects a light pattern such as a projected boundary marker line onto the ground surface adjacent to the aircraft to mark a safe collision-free approach path.

What is claimed is: 1. A guidance system for guiding an aircraft service vehicle to a prescribed parking position adjacent to an aircraft, comprising first and second indicator markers arranged spaced apart from one another on said aircraft, wherein said indicator markers are positioned relative to one another to present a first prescribed visual pattern of said indicator markers along a first line of sight defining a first safe approach path for a driver of said service vehicle to follow when driving said service vehicle to said prescribed parking position, and wherein said indicator markers do not present said prescribed visual pattern away from said line of sight defining said safe approach path. 2. The guidance system according to claim 1, further in combination with said service vehicle and said aircraft, wherein said indicator markers are positioned dependent on locations of parts of said aircraft and dependent on a configuration and dimensions of said service vehicle so that a collision of said service vehicle with any of said parts of said aircraft will be surely avoided if said driver follows said safe approach path when driving said service vehicle to said prescribed parking position. 3. The guidance system according to claim 1, wherein said prescribed visual pattern comprises a superimposed registration of said indicator markers one behind the other along said line of sight. 4. The guidance system according to claim 1, wherein said prescribed visual pattern comprises an apparent vertical alignment of said indicator markers one above the other along said line of sight. 5. The guidance system according to claim 1, wherein said first and second indicator markers respectively comprise first and second marker lights. 6. The guidance system according to claim 5, wherein said first and second marker lights respectively comprise at least one of light emitting diodes and luminescent lamps. 7. The guidance system according to claim 1, wherein said first and second indicator markers are positioned with a horizontal spacing distance of at least 1 meter therebetween. 8. The guidance system according to claim 1, wherein said first indicator marker is arranged on a cargo hold door of said aircraft and said second indicator marker is arranged in a cargo hold of said aircraft. 9. The guidance system according to claim 8, wherein said first indicator marker is arranged at a free swinging edge of said cargo hold door opposite a hinged edge of said cargo hold door. 10. The guidance system according to claim 1, wherein at least one of said indicator markers is arranged on at least one of a cargo hold door threshold, a fuselage side surface, and a fuselage belly surface of said aircraft. 11. The guidance system according to claim 1, further comprising third and fourth indicator markers arranged spaced apart from one another on said aircraft so as to present a second prescribed visual pattern of said third and fourth indicator markers along a second line of sight distinct from said first line of sight and defining a second safe approach path distinct from said first safe approach path. 12. A guidance system for guiding an aircraft service vehicle to a prescribed parking position on a ground surface adjacent to an aircraft, comprising a light projector device that is mounted on said aircraft and that is adapted and oriented to project a light pattern onto said ground surface, wherein said light pattern defines a safe approach path on which said vehicle may be driven to said prescribed parking position without colliding with said aircraft. 13. The guidance system according to claim 12, wherein said light pattern comprises at least one elongated projected light line. 14. The guidance system according to claim 13, wherein said projected light line defines a side boundary of said safe approach path. 15. The guidance system according to claim 12, wherein said light pattern comprises a distinctly illuminated area on said ground surface corresponding to said safe approach path. 16. The guidance system according to claim 12, wherein said light projector device comprises a light source adapted to emit light and an optical arrangement including at least one of a lens, a collimator, an aperture, a diaphragm, and a shutter adapted to project said light in said light pattern onto said ground surface. 17. The guidance system according to claim 12, wherein said light projector device comprises a light source selected from the group consisting of flash lamps, lasers, light emitting diodes, incandescent lamps, and discharge lamps. 18. The guidance system according to claim 12, wherein said light projector device is mounted on a side of a fuselage next to a cargo hold door of said aircraft. 19. The guidance system according to claim 12, wherein said light projector device is mounted on an engine nacelle of an engine of said aircraft.
