Gas turbine engine with dynamic data recording

A method comprising:

• receiving an engine control dynamic data recording request from an offboard system at a communication adapter of a gas turbine engine of an aircraft, wherein the engine control dynamic data recording request comprises a list of supplemental parameters to be recorded during operation of the gas turbine engine in addition to a default parameter recording list as part of a data recording list;
• confirming an authentication between the communication adapter and the engine control, wherein the authentication includes verifying a credential between the communication adapter and the engine control;
• transferring the engine control dynamic data recording request received at the communication adapter from the offboard system to the engine control based on the authentication;
• receiving a confirmation message from the engine control, wherein the confirmation message is sent based on a validation of at least one digital signature associated with the data recording list prior to updating the engine control;
• and
• transmitting an update completion confirmation of the engine control from the communication adapter to the offboard system based on the confirmation message from the engine control.

A gas turbine engine of an aircraft, the gas turbine engine comprising:

• a fan section comprising a fan case;
• an engine control mounted on the fan case, the engine control configured to monitor and control operation of the gas turbine engine in real-time;
• and
• a communication adapter mounted on the fan case, the communication adapter comprising processing circuitry configured to:
• receive an engine control dynamic data recording request from an offboard system, wherein the engine control dynamic data recording request comprises a list of supplemental parameters to be recorded during operation of the gas turbine engine in addition to a default parameter recording list as part of a data recording list;
• confirm an authentication between the communication adapter and the engine control, wherein the authentication includes verifying a credential between the communication adapter and the engine control;
• transfer the engine control dynamic data recording request received at the communication adapter from the offboard system to the engine control based on the authentication;
• receive a confirmation message from the engine control, wherein the confirmation message is sent based on a validation of at least one digital signature associated with the data recording list prior to updating the engine control;
• and
• transmit an update completion confirmation of the engine control to the offboard system based on the confirmation message from the engine control.
