In the CRJ - pretty much every airline jet except the DO-JET(what's up with the boots???) - the wing leading edges are heated with engine bleed air for anti-ice purposes. There are a number of problems that can occur that can cause too much bleed air to go to the wing which causes the 'wing overheat' and of course if the leading edge gets too hot that can cause damage.

"Wing Overheat" is a warning message and audible warning generated by the aircraft EICAS. The leading edges of the wings are heated by perforated tubes just underneath the aircraft skin, fed by 14th stage bleed air from the engines (=HOT) for anti-ice. That message is triggered when a sensor detects an overheat in one of those anti-ice bleed ducts.

If the aircraft wing struck an object on takeoff that air duct could be damaged, leak,and trigger the overheat warning.
 
Good to know you are learning something in that sim back there

. I've always wondered about why the DoJet had boots? Something to do with the high wing? I would think ice could still break off and fall into the intake.

How?
 
Yeah - the DO JET engines sit in front of the wing - not much chance of the ice blowing forward when you pop the boots.

Unless that Citation goes whizzing past you at cruise altitude.

D'oh! Double kill! Killing spree!

Sorry, still hyped up at playing Medal of Honor: Allied Assault online with the JC crew.
 
It was my understanding that the Do Jet had much in common with the turboprop version. Many turboprops do not have enough bleed air to run a hot wing and have boots. If they basically used the same wing and systems as the turboprop, this could explain the boots.
