Reading the question found here: Do some aircraft lower the landing gear mid-flight
Some of the replies got me curious... Do heavy jets or even business jets have brake temp sensors or indicators?
In the fast-movers we don't have this luxury and I've never even heard of it until now. If we suspect hot brakes we just taxi to the hot brakes area and either wait or ground egress if a fire may occur. We do have wheel speed sensors with anti-skid brakes that use different channels, but nothing that reports to the pilot the brake temperature.
If you guys do have this feature, do you have a indicator that shows brake temperature? Or is there a light that illuminates or even a PFL (pilot fault list) that appears on one of the MFDs?
