Captain reported the loss of the second Air Data Computer during final descent.

Narrative

During final descent into ZZZ; Co Pilot's PFD Altitude Tape (ADC2) Failed. Ran appropriate Emergency Checklist. Reverted to ADC1 only operations. Requested extended radar vectors and called ZZZ1 Operations and Maintenance. Maintenance directed to land as soon as practical and call after safe landing. Continued normal descent; approach; and landing without further incident. The PIC (Pilot in Command) [requested priority handling] due to the following factors: last flight on long duty day; entrance into extremely busy Class B area airspace; New FO (First Officer) in right seat; Emergency Checklist usage; and busy night flight operations into windy ZZZ airport area.Suggest that all ZZZ1 CE560XL ADC computers be checked for faulty and/or corrupted data. Suggest that all ZZZ1 CE560XL crews be given recommended in-flight procedures (to be printed & kept in aircraft binders) to cover in-flight and on-the-ground resets of the ADC/avionics systems (if any such procedures exist outside of CE560XL manufacturer emergency/abnormal checklists).
