What is the make and model of the APU?

Explanation:
The APU on this aircraft is the Allied Signal RE 220 with the RJ designation. This model is the specific RE 220 variant used on regional jets like the CRJ family, and the RJ suffix identifies the regional jet version. The 210 variant is a different APU, so it wouldn’t match the installation, and GE doesn’t supply this particular APU for the CRJ line. Note that after Allied Signal’s merger, the same unit may be branded Honeywell in newer materials, but the make and model commonly associated with this aircraft in manuals and practice questions is Allied Signal RE 220 (RJ).
