초록 ▼

In the vertical path control of an area navigation system when the aircraft ascends or descends to a waypoint with an “at-or-above”or “at-or-below”altitude requirement, vertical steering is effected at a constant airspeed with regard to a reference airspeed. An alert device is included to provide a warning to the pilot when the aircraft flight path angle is less than the straight line flight path angle to the waypoint for “at-or-above”waypoints or when the flight path angle of the aircraft is greater than the straight line flight path angle to the waypoint for waypoints with an “at-or-below”altitude requirement. Altitude error is displayed on a vertical deviation indicator of an aircraft flight instrument in accordance with the difference between the actual aircraft altitude and the altitude of the next waypoint having a firm altitude requirement. When the aircraft ascends or descends to a waypoint through the pressure-barometric altitude transition, flight path angles are computed and utilized as the vertical steering reference to avoid a steering discontinuity at the transition altitude. When the aircraft is on a descent path to a waypoint and an airspeed reduction is required, vertical angles are computed and utilized for generating the vertical steering signal whereby a speed reduction transition zone is included in the flight path to effect the speed reduction and make good the desired waypoint altitude.

In an area navigation system for aircraft, apparatus for controlling the vertical flight path of the aircraft when ascending or descending to a waypoint having an altitude and an “at-or-above”or an “at-or-below”altitude requirement associated therewith comprising vertical steering signal generating means for generating a vertical steering signal representative of deviations of the airspeed of said aircraft from a reference airspeed, pitch axis control means responsive to said vertical steering signal for controlling the pitch attitude of said aircraft so as to reduce said speed deviations to zero, boundary parameter computing means for providing a boundary parameter signal representative of the value of a suitable aircraft parameter on a boundary flight path defined by a straight line from the instantaneous location of said aircraft to said waypoint at said altitude thereof, aircraft parameter computing means of providing an aircraft parameter signal representative of the instantaneous actual value of said aircraft parameter, means for providing a waypoint data signal representative of said “at-or-above”or said “at-or-below”designation of said waypoint, comparator means responsive to said boundary parameter signal, said aircraft parameter signal and said waypoint data signal for comparing said aircraft parameter signal to said boundary parameter signal in accordance with said waypoint data signal and providing a pilot alert signal when said actual value of said aircraft parameter relative to said boundary value thereof indicates an actual aircraft flight path tending to violate said “at-or-above”or said “at-or-below”altitude requirement of said waypoint, and pilot alert means responsive to said pilot alert signal for providing a warning that said aircraft is tending to violate said “at-or-above”or said “at-or-below”altitude requirement.
