I will shoot them an email. Thanks
You could look at what savings can be had replacing the steam gauges in the cockpit with updated systems. The engineers replaced the iron gyros on our fleet with AHRS (Attitude and heading reference system) because of failure rates and attendant maintenance/repair/downtime costs. We already had a glass cockpit, but
weight savings can be had by modernising the cockpit. Difficult to quote actual $ savings without having access to substantive figures.
Interesting! Never herd of AHRS before! Will definitely investigate further.
