Multiple power assurance check procedure for aircraft with an engine inlet barrier filter installed

A method of conducting an engine power assurance check, comprising:

• selecting, via a touchscreen interface, one of a first engine power assurance check according to a first set of criteria related to an inlet barrier filter and a second engine power assurance check according to a second set of criteria related to the inlet barrier filter;
• and
• conducting the selected one of the first engine power assurance check and the second engine power assurance check, wherein the conducting the selected one of the first engine power assurance check and the second engine power assurance check comprises operating an engine, wherein the second set of criteria is different relative to the first set of criteria, and wherein the second engine power assurance check is conducted in response to a fail result of the first engine power assurance check, wherein the first set of criteria are based on engine performance charts calculated based on an assumption that the inlet barrier filter is installed, and wherein the second set of criteria are based on engine performance charts calculated based on an assumption that the inlet barrier filter is not installed or is bypassed.

An aircraft, comprising:

• an inlet barrier filter;
• and
• an integrated avionics control system configured to selectively conduct (1) a first engine power assurance check with a bypass of the inlet barrier filter closed and according to a first set of criteria related to the inlet barrier filter and (2) a second engine power assurance check with the bypass of the inlet barrier filter open and according to a second set of criteria related to the inlet barrier filter, wherein the second set of criteria is different relative to the first set of criteria and wherein the second power assurance check is conducted in response to a fail result of the first power assurance check, wherein the first set of criteria are based on engine performance charts calculated based on an assumption that the inlet barrier filter is installed, and wherein the second set of criteria are based on engine performance charts calculated based on an assumption that the inlet barrier filter is not installed or is bypassed.
