How answers work
AeroCite writes answers from the clauses it finds. Each statement about the regulations cites its source and is checked automatically against that clause. Document issues and dates are shown where available.
Credits
A written answer uses 1 credit when it passes the checks and is saved to History, including an answer that covers only part of your question. No credit is used if nothing relevant is found, the answer fails the checks, the request fails, or you cancel before it is saved.
Before relying on an answer
Coverage is limited to the documents AeroCite has indexed. Recent changes may not be included. Check the cited text against the current official document before relying on an answer. AeroCite is a research aid, not an official interpretation or approval.
