Every answer traced to the clause.
Ask about SORA 2.5, the EASA means of compliance for the OSOs, or the RTCA DO-standards. UASCERT answers in plain English and quotes the source word for word, with the document and section, so you can check it before it goes into your application.

Can I claim M1(A) at medium robustness together with an M1(B) mitigation?
No. At medium robustness, M1(A) sheltering already includes time-based arguments, so pairing it with any M1(B) mitigation would count the same reduction twice. M1(A) at low robustness has no operational restrictions and can be combined with M1(B).
To prevent double counting time-based restrictions, M1(A) medium robustness mitigation cannot be combined with any M1(B) mitigations.
Certification work is mostly finding the right sentence.
1,540 pages from three publishers
The SORA main body and annexes come from JARUS, the OSO means of compliance from EASA, the DO-standards from RTCA. Each numbers its sections its own way.
Every requirement points somewhere else
An OSO robustness level leads to a means of compliance, which leads to a DO-standard section. One question can take an afternoon of cross-referencing.
Expert hours are scarce
Consultants are expensive and booked out. Small questions wait in the same queue as big ones and hold up the rest of the application.
General chatbots invent clauses
They cite sections that don't exist, with total confidence. In front of an authority, a wrong reference costs more than no reference.
How an answer is built
Ask in your own words
Write the question the way you would ask a colleague, in English or any other language.
The source documents are searched
Only the released SORA, EASA and RTCA texts, split along their own sections so tables and footnotes stay whole.
Every quote is checked
Each quoted passage is matched word for word against the source. A quote that doesn't match is removed; a claim left without support is marked unverified.
When the documents don't cover a question, UASCERT says so instead of guessing. You can then choose to search the web, and those answers are labelled as web-sourced.
