A preexisting FMS system may be upgraded to increase its functionality by optimizing the control of autopilot and auto-throttle functions and replacing other preexisting components with different components for enhancing the functionality of the FMS system. The preexisting IRU, CADC, DME receiver and DFGC in the upgraded FMS system are in communication with the legacy AFMC but, instead of employing the legacy EFIS, the EFIS is replaced by a data concentrator unit as well as the display control panel and integrated flat panel display, and a GPS receiver. The upgraded FMS system is capable of iteratively controlling the autopilot and auto-throttle during all phases of flight and of such increased functionality as increased navigation database storage capacity, RNP, VNAV, LPV and RNAV capability utilizing a GPS based navigation solution, and RTA capability, while still enabling the legacy AFMC to exploit its aircraft performance capabilities throughout the flight.

1. A flight management system (FMS) comprising: an advanced flight management computer (AFMC) having aircraft performance capabilities exploitable throughout a flight of an aircraft;an inertial reference unit (IRU) configured to measure navigation data;a central air data computer (CADC) configured to compute data associated with the flight of the aircraft;a distance measuring equipment (DME) receiver configured to measure distance based on radio signals;a digital flight guidance computer (DFGC) configured to manipulate guidance information, wherein the IRU, CADC, DME receiver and DFGC are connected to the AFMC;a data concentrator unit (DCU) configured to collect data associated with the flight of the aircraft from the CADC and navigation data from the IRU, wherein the DCU and the AFMC are operatively connected to each other to exchange input and output information therebetween, and are further operatively connected to the DFGC to receive output information therefrom;a global positioning system (GPS) receiver operatively connected to the DCU for providing input information thereto; anda multipurpose control display unit (MCDU) comprising a microprocessor, a navigation (NAV) computer capable of providing an autopilot function, and a navigation database whereby the NAV computer and the navigation database are operatively connected to the DCU and the AFMC and whereby the MCDU is configured to: receive input indicating a phase of flight,monitor performance of the aircraft by continuously measuring flight parameters associated with the phase of flight,convert the measured flight parameters associated with the phase of flight into control signals, andcontrol the autopilot function and an auto-throttle function based on the control signals. 2. The FMS in accordance with claim 1, wherein a phase of flight comprises Instrument Landing approach, take-off and cruise. 3. A method of controlling an autopilot function and auto-throttle function in a flight management system (FMS) of an aircraft, the aircraft including: (i) an advanced flight management computer (AFMC) having aircraft performance capabilities exploitable throughout a flight of an aircraft; (ii) an inertial reference unit (IRU) configured to measure navigation data; (iii) a central air data computer (CADC) configured to compute data associated with the flight of the aircraft; (iv) a distance measuring equipment (DME) receiver configured to measure distance based on radio signals; (v) a digital flight guidance computer (DFGC) configured to manipulate guidance information, wherein the IRU, CADC, DME receiver and DFGC are connected to the AFMC; (vi) a data concentrator unit (DCU) configured to collect data associated with the flight of the aircraft from the CADC and navigation data from the IRU, wherein the DCU and the AFMC are operatively connected to each other to exchange input and output information therebetween, and are further operatively connected to the DFGC to receive output information therefrom; (vii) a global positioning system (GPS) receiver operatively connected to the DCU for providing input information thereto; and (viii) a multipurpose control display unit (MCDU) comprising a microprocessor, a navigation (NAV) computer capable of providing an autopilot function, and a navigation database whereby the NAV computer and the navigation database are operatively connected to the DCU and the AFMC; the method comprising the steps of: receiving input indicating a phase of flight;monitoring performance of the aircraft by continuously measuring flight parameters associated with the phase of flight;converting the measured flight parameters associated with the phase of flight into control signals; andcontrolling the autopilot function and an auto-throttle function based on the control signals. 4. The method in accordance with claim 3, wherein a phase of flight comprises Instrument Landing approach, take-off and cruise.
