The FAA also wants deicing boots installed on the plane's forward baggage pod. Bernstein notes that this was a requirement in an earlier directive.
FedEx says that it has already installed these deicing devices on half of its fleet.
In addition, FedEx notes that it is going beyond the directive and installing the Garmin multi-function displays with terrain avoidance awareness systems and a WSI satellite receiver to obtain "real time" weather information.
In its comments, Bernstein says RACCA is just seeking "fine tuning" of the language.
In one comment, Stephen McClure, of Bennington, Vt., questions the need for the low airspeed awareness system. "The aircraft already has such a system. It is called the airspeed indicator. The idea that you need another annunciator light or aural tone to remind you that your airspeed is decreasing in icing conditions is laughable," McClure writes.
