Takeoff Performance Monitor (TOPM) System, Airplane, Minimum Performance Standard for(STABILIZED May 2020)
This Aerospace Standard (AS), establishes minimum performance standards for those sensors, computers, transponders, and airplane flight deck controls/displays which together comprise a Takeoff Performance Monitor (TOPM) System. This standard also defines functional capabilities, design requirements, and test procedures. A TOPM system is intended to monitor the progress of the takeoff and to provide advisory information which the crew may use in conjunction with other available cues to decide to continue or abort the takeoff. See Appendix A for supplementary information relating to NTSB, CAA, and ad hoc committee concerns and background information.
This standard has been stabilized because the function of takeoff performance monitoring has moved from a separate or federated avionics system to one being incorporated within aircrafts’ Integrated Modular Avionics (IMA) architectures. Thus, the display philosophy of those integrated modular avionics will prevail over the design requirements of a standalone system.
