SUMMARY: This notice announces the issuance of Advisory Circular (AC) 
23.1523. This Advisory Circular (AC) sets forth one method that may be 
used to show compliance to the requirements contained within 14 CFR, 
part 23, 23.1523, which prescribes the certification requirements for 
minimum flight crew on part 23 airplanes. This AC is one method that 
can be used to determine workload factors and issues for normal, 
utility, acrobatic and commuter category airplanes. Material in this AC 
is neither mandatory nor regulatory in nature and does not constitute a 
regulation.
    This material is a reference for part 23 airplane manufacturers, 
modifiers, Federal Aviation Administration (FAA) design evaluation 
engineers, flight test engineers, engineering flight test pilots 
[Aircraft Certification Office (ACO), and Flight Standards, and 
Manufacturers] as well as human factors engineering evaluators. This 
material may be used by FAA authorized designees to perform workload 
evaluations. This AC encourages participation and coordination from all 
the test community participants described above. This AC is consistent 
with the flight test guidance and workload factors described in the 
minimum flight crew evaluation sections and workload factors described 
in AC 23-8B. This AC is an acceptable means of showing compliance for 
part 23 on flight tests and pilot judgments.
    The draft advisory circular was issued for Public Comment on July 
2, 2004 (69 FR 40451). When possible, comments received were used to 
modify the draft advisory circular.
