In exemplary embodiments, a system includes multiple aircraft, wherein an aircraft in the multiple aircraft communicates through one or more communication links. The aircraft includes processors that compile network event information related to degraded communication link events. Further, the aircraft includes memory units that store a degraded link event report and a configuration database, wherein the degraded link event report stores the network event information related to the degraded communication link events as directed the configuration database. The system additionally includes a network issue detector, in communication with the multiple aircraft, which receives degraded link event reports from the multiple aircraft, wherein the network issue detector includes processors that identify systemic degraded data link network problems with the communication links based on context identified in the degraded link event reports. ## Claims ### Claim 1 A system comprising: a network issue detector configured to receive degraded link event reports from multiple aircraft through one or more data communication links, wherein each of the multiple aircraft comprises one or more aircraft processors that compile network event information related to degraded communication link events in a degraded link event report, wherein the degraded link event report describes context surrounding the degraded communication link events from a perspective of an aircraft in the multiple aircraft, wherein the network issue detector comprises: one or more network issue detector processors that identify systemic degraded data link network problems with the one or more data communication links for time and location based on the context identified in the degraded link event reports. ### Claim 2 (depends on 1) The system of claim 1, wherein the one or more aircraft processors are part of a communication management unit. ### Claim 3 (depends on 1) The system of claim 1, wherein the network issue detector receives the degraded link event report from the aircraft in response to sending a request for the degraded link event report from the network issue detector. ### Claim 4 (depends on 1) The system of claim 1, wherein the network issue detector receives the degraded link event report from the aircraft that was automatically sent by the aircraft. ### Claim 5 (depends on 4) The system of claim 4, wherein the aircraft automatically sends the degraded link event report to the network issue detector after at least one of: expiration of a period; occurrence of a communication triggering event; and occurrence of a report triggering event. ### Claim 6 (depends on 5) The system of claim 5, wherein the communication triggering event includes at least one of: communication loss through the one or more data communication links; communication degradation through the one or more data communication links below a measurable threshold; and communication resumption through the one or more data communication links after the communication loss. ### Claim 7 (depends on 1) The system of claim 1, wherein the network issue detector sends instructions to the aircraft that direct compilation of the network event information by the one or more aircraft processors according to the instructions stored in a configuration database stored on the aircraft. ### Claim 8 (depends on 7) The system of claim 7, wherein the aircraft stores the instructions in the configuration database. ### Claim 9 (depends on 7) The system of claim 7, wherein the instructions specify the network issue detector as a recipient for a transmission of the degraded link event report. ### Claim 10 (depends on 1) The system of claim 1, wherein the degraded link event report keeps at least one of: statistical information related to the communications through the one or more data communication links; identified issues that arise during the communications through the one or more data communication links; information related to quality of the communications through the one or more data communication links;
