SPZ--8000 Digital Integrated Flight Control System System Limits GLOSSARY OF TERMS This glossary gives a brief description of the flight guidance computer control laws. These terms are used throughout this section and the Modes of Operation section. The performance and operating limits for these items are defined in Table 7--1.
SPZ--8000 Digital Integrated Flight Control System Glideslope Gain Programming Gain programming starts after the VBS trips. The gain is programmed as a function of radio altitude and vertical speed. If the radio altimeter is invalid, gain programming occurs at glideslope capture and is controlled by a runway height estimator.
SPZ--8000 Digital Integrated Flight Control System Lateral Beam Sensor (LBS) When flying to intercept the VOR or LOC beam, the LBS is tripped as a function of beam deviation, course error, TAS, and DME. In the LOC mode, the course error is compared with the beam deviation signal and rate of crossing the beam to determine the LBS trip point.
SPZ--8000 Digital Integrated Flight Control System LOC TRACK 1 and BC TRACK 1 Localizer track 1 and back course track 1 mean the aircraft is on beam center and the roll rate limit is decreased from 7.0/second (during the capture phase) down to 5.5/second. When track occurs, the course error is eliminated from the control signal, leaving beam deviation and lateral acceleration from the IRS to maintain the aircraft on beam center.
SPZ--8000 Digital Integrated Flight Control System Vertical Beam Sensor (VBS) The VBS determines the point of glideslope capture using a number of inputs. The VBS is armed when NAV radio is tuned to a LOC frequency, the LOC receiver is valid, and the LBS has tripped. The VBS trips as a function of vertical speed, TAS, and glideslope deviation.
SPZ--8000 Digital Integrated Flight Control System VOR Over Station Sensor (VOR OSS) The OSS detects the erratic radio signals encountered in the area above the VOR transmitter. When these radio signals reach a certain level of deviation, they no longer are useful and the OSS eliminates them from the control signal.
SPZ--8000 Digital Integrated Flight Control System VOR AOSS 2 occurs when the following conditions are all satisfied: — VOR AOSS 1 has tripped plus 3 seconds — Beam deviation is less than 2 dots — Once VOR AOSS 2 trips, beam deviation is again part of the control signal.

SPZ--8000 Digital Integrated Flight Control System Modes of Operation HEADING HOLD AND WINGS LEVEL The basic lateral mode of the autopilot is heading hold. Heading hold is defined as: Autopilot engaged (AP) No lateral flight director mode selected Bank angle less than 6. If these conditions are satisfied, the autopilot rolls the aircraft to a wings level attitude.
SPZ--8000 Digital Integrated Flight Control System ROLL HOLD MODE The autopilot recognizes the roll hold mode as being operational when: No lateral flight director mode is selected and, The aircraft’s bank angle is greater than 6, but less than 45 and, Touch control steering (TCS) was used to initiate the roll maneuver.
SPZ--8000 Digital Integrated Flight Control System HEADING SELECT MODE The heading select mode is used to intercept and maintain a magnetic heading. The mode is engaged by pushing the HDG button on the flight guidance controller. is annunciated on the EADI. Engaging the heading select mode resets all previously selected lateral modes.
SPZ--8000 Digital Integrated Flight Control System VOR (NAV) MODE The VOR mode automatically intercepts, captures, and tracks a selected VOR radial, using the selected navigation source displayed on the EHSI. The navigation source displayed on the EHSI is selected with the NAV source buttons on the display controller.

SPZ--8000 Digital Integrated Flight Control System The flight guidance computer generates the proper roll command to bank the aircraft to capture and track the selected VOR radial, as shown in Figure 8--6. VOR (NAV) Mode Capture Profile Figure 8--6 When the course select pointer is set on the EHSI using the CRS knob on the instrument remote controller, the course select error signal is established.
SPZ--8000 Digital Integrated Flight Control System When flying a VOR intercept, the optimum intercept angle should be less than 45. If the intercept angle is greater than 45, course cut limiting may occur. The course cut limiter works primarily when approaching the VOR radial at an intercept angle that is greater than 45...
SPZ--8000 Digital Integrated Flight Control System When the aircraft satisfies VOR track conditions, the course error signal is removed from the lateral steering command. This leaves radio deviation, roll attitude, and lateral acceleration to track the VOR signal and to compensate for beam standoff in the presence of a crosswind. The system automatically compensates for a crosswind of up to 45...
SPZ--8000 Digital Integrated Flight Control System VOR Over Station Operation As the aircraft approaches the VOR station, it enters a zone of unstable radio signal, as shown in Figure 8--9. This zone of confusion radiates upward from the station in the shape of a truncated cone. In this area, the radio signal becomes erratic and it must be removed from the roll command.
SPZ--8000 Digital Integrated Flight Control System VOR DIRECT TO Function Another option is to fly a VOR intercept that has a zero deviation to the VOR station. This procedure is described in Table 8--2. Step Procedure Establish the VOR intercept as previously described. Set the bearing selector to the same NAV source that is being used for the VOR intercept on the display controller.

SPZ--8000 Digital Integrated Flight Control System TROUBLESHOOTING DIGITAL AVIONICS Maintenance of digital flight control systems requires a different approach than that of analog systems. Crew members and maintenance personnel can more effectively operate this digital system by understanding the differences between it and analog systems. Control law functions, once done with resistors, capacitors, coils, and op amps, are now programmed digitally with microprocessors.
SPZ--8000 Digital Integrated Flight Control System A digital system is more likely to have an external sensor problem (i.e., MADC, gyros, accelerometers, NAV/DME), than it is to have a problem with the avionics computers. The avionics computers perform extensive self--testing and continuous monitoring that positively affects maintainability and reliability.
