The presence of the military in the most diverse regions of the country, including in the borders, is essential for the maintenance of Brazilian sovereignty. In many of these locations, the difficulty of access makes the maintenance of the State`s presence dependent on missions carried out with the use of military aircraft compatible with the airfields landings and takeoffs available in the locations.

In this context, the Brazilian Amazon stands out, a region of approximately 5.5 million square kilometers (km2), with low demographic density, where the means of transport are predominantly fluvial and aerial.

For these reasons, is essential the support with FAB aircraft in the Amazon Region in order to enable the presence of numerous government agencies as the Ministry of Health, the Ministry of Justice and the National Indian Foundation - FUNAI, among others, to enable integration between the capitals and the several municipalities in the interior of the States and to guarantee support to the countless Military Organizations of the Navy, Army and Air Force, mainly in remote regions.

The Amazon Region has paved airports, but the aerodromes that serve small municipalities and the Brazilian Army`s Frontier Platoons, for the most part, have small, unpaved runways (earth, gravel and grass), in addition to being in restricted areas, with trees and other obstacles close to the sides.

To operate in medium and large airports, COMAER currently uses the C-130 (Hercules), C-105 (Amazonas) and C-97 (Brasília) aircraft and, to operate in locations that have short runways (between 800 and 1,200m), the C-95 (Bandeirante) and C-98 (Caravan) aircraft are used. In the case of the C-98 aircraft, which operates on unpaved runways, COMAER`s capacity is very limited due to the small number of these aircraft, in addition to the reduced cargo and passenger capacity.

Due to the characteristics of the Amazon Region, serious challenges are imposed to the military` capacity for strategic mobilization. Although currently mitigated by the use of existing aircraft, the difficulties imposed on the displacement of personnel and material to some locations, in situations that require the use of aircraft from more remote runways, can degrade the performance of military forces and hinder the projection of power aerospace throughout the entire national territory.

The concept of operations this project is based on the needs of the FAB, i.e., of a new fleet of light military transport aircraft, intended for use throughout the national territory. with an emphasis on the Amazon region.

The initial concept for the acquisition and operation of this new aircraft follows below:

a) The design should be of a multi-engine aircraft;

b) With retractable tricycle landing gear;

c) With rear door that allows loading in the longitudinal direction of the aircraft;

d) With high wing;

e) In order to be able to be operated by only a single pilot; and

f) Its employment in the Specialization Program and in the Operational Elevation Program for Aviation Officers must be feasible, carrying out the training and operational maintenance of COMAER crew members in:

- Airborne Assault Actions,

- Air Exfiltration,

- Air Infiltration, and

- TAL, according to the standards established by COMPREP (NOPREP TTP 14 and 18, INPREP PESOP 05).

g) Must be operative on unpaved and short runaways, where ground transportation infrastructure is inadequate or does not exist, robust and easy of maintaining, pax or cargo transport, aft cargo ramp, quick-change for ambulance, humanitarian evacuation, fully equipped paratroopers, troops, and operates in a range greater than 1600 km.

Concept of Operations (CONOPS) for a given system (limited to an enterprise or business or capability system) is a description of the concept of how human and technical resources within the system solution are to interact to result in the enterprise or business or capability outcome. That is, a CONOPS is a conceptual description of  the operational part of the system solution. The operational part of the system solution is that part of the solution which is intended to meet the requirements on the system which serve an end-use purpose
