An aircraft brake control system accommodates desired yaw for steering, while substantially eliminating undesired yaw. The system assesses brake command signals from the pilot, signals corresponding to aircraft parameters, and signals based on brake control parameters, and determines therefrom an amount of yaw desired by the pilot. The instantaneous yaw rate is monitored and compared to the desired yaw rate. An error signal corresponding to the difference between instantaneous and actual yaw rates is calculated and that error signal is employed to modify a braking differential between right and left brakes to eliminate or substantially reduce the undesired yaw.

A heat shield assembly is disclosed. In various embodiments, the heat shield assembly defines a first circumferential side and a second circumferential side and an inboard end and an outboard end and includes a first layer defining a first surface of the heat shield assembly and having a first tab member disposed proximate the inboard end at the first circumferential side and a second tab member disposed proximate the outboard end at the first circumferential side; and a second layer defining a second surface of the heat shield assembly and having one or more first crimped portions extending along the first circumferential side and configured to engage the first tab member and the second tab member.
