Conventional terrain anticollision equipment formulates, around the short term forecast trajectory of the aircraft which is equipped therewith, virtual volumes of protection of maneuver charted by feelers and signals a risk of terrain collision as soon as it detects an intrusion of the terrain into these virtual volumes of protection of maneuver. The terrain anticollision equipment proposed provides the crew with, in addition to the prealarms and alarms of risk of terrain collision, an indication of possibility of cessation of an avoidance maneuver instigated in order to resolve a risk of terrain collision, in the form either of a stoppage of an aural and/or luminous cue to continue the avoidance maneuver, or of the momentary generation of an aural and/or luminous cue of possible end of the avoidance maneuver, formulated by means of a feeler specific to route resumption, the absence of contact of the terrain with this feeler specific to route resumption being used to note the definitive resolution of a risk of terrain collision.

The equipment as claimed in claim 1, wherein the fictitious trajectory of resumption of route is a horizontal trajectory. 3. The equipment as claimed in claim 1, wherein the fictitious trajectory of resumption of route is a trajectory having as slope a horizontal slope when the instantaneous trajectory of the aircraft is climbing or holding level, and a slope dependent on the instantaneous trajectory of the aircraft when the aircraft is descending. 4. The equipment as claimed in claim 1, wherein the fictitious trajectory of resumption of route is a trajectory having as slope a slope dependent on the instantaneous trajectory of the aircraft. 5. The equipment as claimed in claim 4, wherein the fictitious trajectory of resumption of route is a trajectory having as slope a slope dependent on the trajectory of the aircraft at the moment of the detection of the risk of terrain collision. 6. The equipment as claimed in claim 1, wherein the fictitious trajectory of resumption of route is a trajectory having as slope a slope dependent on the trajectory of the aircraft at the moment of the detection of the risk of terrain collision, when the aircraft was descending, and a horizontal trajectory when the aircraft was flying horizontally or climbing at the moment of the detection of the risk of terrain collision. 7. The equipment as claimed in claim 1, wherein the fictitious trajectory of resumption of route is a trajectory having as heading the instantaneous heading of the aircraft. 8. The equipment as claimed in claim 1, wherein the fictitious trajectory of resumption of route is a trajectory having as heading and slope those of the trajectory of the aircraft at the moment of the detection of the risk of terrain collision. 9. The equipment as claimed in claim 1, wherein the limits of the virtual envelopes of protection are defined by a so-called feeler surface, the meeting of which with the representation of an envelope of the terrain and/or of the ground obstacles which is extracted from the information of the data base is regarded as an intrusion of the terrain and/or of the ground obstacles into the corresponding virtual envelope of protection. 10. The equipment as claimed in claim 9, wherein, regardless of the instantaneous attitude of the aircraft, the projection onto the horizontal of a feeler of virtual envelope of protection of maneuver is adopted as feeler of a virtual envelope of protection of resumption of route. 11. The equipment as claimed in claim 9, wherein, when the instantaneous attitude of the aircraft is climbing at flying level, the projection onto the horizontal of a feeler of virtual envelope of protection of maneuver is adopted as feeler of a virtual envelope of protection of resumption of route. 12. The equipment as claimed in claim 9, wherein, when the instantaneous attitude of the aircraft is descending, the projection according to an inclined plane dependent on the instantaneous descent slope of the aircraft of a feeler of virtual envelope of protection of maneuver is adopted as feeler of a virtual envelope of protection of resumption of route. 13. The equipment as claimed in claim 1, wherein, when the instantaneous attitude of the aircraft is descending, the projection along an inclined plane dependent on the instantaneous descent slope of the aircraft of a feeler of virtual envelope of protection of maneuver during a certain distance or flight time and then according to the horizontal is adopted as feeler of a virtual envelope of protection of resumption of route. 14. The equipment as claimed in claim 13, wherein, when the terrain anticollision equipment is provided with a display screen showing a representation of the terrain layers and/or of risk with the terrain and/or the obstacles overflown, the projection, in two planes, which is adopted as feeler of a virtual envelope of protection of resumption of route is carried out in a manner consistent with that used on the screen for the representation of the terrain layers and/or of risk with the terrain and/or the obstacles overflown. 15. The equipment as claimed in claim 1, wherein when the aircraft was climbing or holding level at the moment of the detection of the risk of terrain collision, the projection onto the horizontal of a feeler of virtual envelope of protection of maneuver is adopted as feeler of a virtual envelope of protection of resumption of route. 16. The equipment as claimed in claim 1, wherein, when the aircraft was descending at the moment of the detection of a risk of terrain collision, the projection, along an inclined plane having the descent slope of the aircraft at the moment of the detection of the risk of terrain collision, of a feeler of virtual envelope of protection of maneuver is adopted as feeler of a virtual envelope of protection of resumption of route. 17. The equipment as claimed in claim 1, wherein, when the means for determination of virtual envelope of protection produce two virtual envelopes of protection of maneuver, the more distant for a prealarm of terrain collision and the closer for an alarm of terrain collision and when the aircraft is climbing or holding level, the union of the projections onto the horizontal of the feelers of the two virtual envelopes of protection of maneuver is adopted as feeler of a virtual envelope of protection of resumption of route. 18.
