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.

Ya veo que no has leído el artículo que puse.
Lepanto escribió:El diario holandés De Telegraaf, informa de que que Holanda va a adquirir una 14 helicópteros H225 Caracal para reemplazar los 12 AS532 Cougars en servicio con la Fuerza Aérea para misiones de búsqueda y rescate de transporte y combate.
Aún no está definido el importe del contrato anunciado por la ministra, que se estima entre 1.000 y 2.500 millones de euros. En el proceso de selección aplicado se evaluaron varios aparatos y solo el Caracal y el Blackhawk cumplieron con las expectativas de las fuerzas especiales holandesas. El tamaño de la cabina y el equipamiento llevaron finalmente a la elección del Caracal.

La Fuerza Aérea Brasileña recibe su primer helicóptero con sonda de reabastecimiento
...Además de su inédito sistema de reabastecimiento, el helicóptero Airbus H-36 Caracal está equipado con un moderno sistema de autodefensa.
El nuevo helicóptero, registrado como FAB-8522, forma parte del ambicioso proyecto H-XBR, un acuerdo de años atras entre la Marina, el Ejército y la Fuerza Aérea Brasileña que resultó en la adquisición de un total de 47 unidades, la mayoría ensamblada localmente en Helibras.
