Ya veo que no has leído el artículo que puse. Como ya se ha dicho, los requerimientos son públicos y están accesibles para todo el mundo (propuesta para modificar el ADS-33 de 2019, adecuándolo al FVL):

Aeronautical Design Standard–33 (ADS-33) is a United States Army rotorcraft handling qualities performance specification that contains criteria suitable for a range of rotorcraft from Scout and Attack to Utility and Cargo. ADS-33 evolved from an effort to update the 1950’s military helicopter flying and ground handling requirements, MIL-H-8501 (Refs. 1 and 2), and the need for new mission-oriented handling qualities requirements for the U.S. Army’s Light Helicopter Experimental program (LHX). In 1987, the Army’s Aviation Systems Command (AVSCOM) adopted the 8501 Update effort as Aeronautical Design Standard–33 (ADS-33) (Ref. 3). It was distributed with the draft request for proposals for LHX, which later evolved into Comanche.
Since the initial 1987-version, full flight-test evaluations of ADS-33 have been performed using: an AH-64A Apache (Ref. 4), a CH-47D Chinook (Ref. 5), a BO 105 (Ref. 6), a variablestability Bell 205, a UH-60A Black Hawk (Ref. 7), and a CH-53G (Ref. 8 ); and partial evaluations using a Puma, AH-1 Cobra, EC-135, MD900, and other rotorcraft (Fig. 1). ADS-33 has been refined four times; the current version is the “E-version,” ADS-33E-PRF (Ref. 9). ADS-33 not only provides design guidance, but detailed methods for compliance assessment (Ref. 10) and has been used on national (Refs. 11-18) and international programs (Ref. 19).
Over the last two decades or so, since Aeronautical Design Standard–33E (ADS-33E-PRF) was published in March 2000, many flight tests and research efforts in the United States (e.g., Refs. 20-33) and abroad (Refs. 34-37) have provided valuable lessons and data to support potential updates to ADS-33E. These have included recommendations for text corrections/clarifications, to changes in existing criteria/requirements, as well as new proposed criteria and Mission Task Elements (MTEs). Note that some of the recommendations will require further research to solidify requirements and boundaries. Also, the proposed recommendations are primarily based on legacy helicopters and do not include lessons learned from recent Future Vertical Lift (FVL) configurations, which will need to be included in future updates. Toward these future updates, new high-speed MTEs, applicable to FVL, have recently been developed and proposed (Refs. 38-41). However, the development of these high-speed MTEs, at this point in time, is based entirely on ground-based simulations. Before inclusion in an ADS-33 update, these MTEs need to be flight tested and lessons learned from these tests included in the MTEs.

Por aquí puedes ver algo sobre el nivel 1, el cual el V-280 supera sin problemas:
Con este estándar también se evaluó al NH90. Frente al excelente 2,67 de este, el V-280 se situaría en el 1 (recordemos la escala Cooper-Harper HQR puesta en la página anterior):
* HQR = Handling Qualities Ratings, MTE = Mission Task Elements
Un par de ejemplos de lo que quieren pedir con la nueva actualización:
* GVE = Good Visual Conditions, DVE = Degraded Visual Conditions
