OG exemplary drawing
 
1. A communication adapter of a gas turbine engine of an aircraft, the communication adapter comprising:
a communication interface configured to wirelessly communicate with an offboard system and to communicate with an engine control of the gas turbine engine;
a memory system; and
processing circuitry configured to:
receive an engine control dynamic data recording request from the 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 from the communication adapter to the offboard system based on the confirmation message from the engine control.
