Compability
Interoperability
1)program for automatically launching missiles with prescribed cyclorama 2)remote flight control 3) access to all indicators of a rocket in space 4) audio / video contact ground-rocket using communication protocols
Co-existence
1)the ability to control an aircraft both from the earth and in space. 2) parallel flight control from earth and space without interfering with each other, since there are priority modes
Functional suitability
-
Functional completeness
Because SpaceX produces one SpaceX BFR core vehicle, satellite customers benefit from the high design standards required to safely transport crew.
Functional correctness
In 2008, NASA selected the SpaceX Falcon 9 launch vehicle and Dragon spacecraft for the International Space Station Cargo Resupply Services contract. NASA has also awarded SpaceX contracts to develop the capability to transport astronauts to spaceas well as to launch scientific satellites. In addition, SpaceX services the National Security community and is on contract with the Air Force for multiple missions on the BFR family of launch vehicles

Reusability
a fully and rapidly reusable rocket=>return a rocket back to Earth intact. (first stage, a single Merlin 1D engine, four steel landing legs with hydraulic dampers, and a steel support structure)
Modularity
a two-stage rocket; nine first-stage engines, it can safely complete its mission even in the event of an engine shutdown; for people: capsule and trunk
Security
Confidentiality
Most ranges consider hazardous systems andoperations to include ordnance operations, pressurized systems that operate below a 4-to-1 safety factor, lifting operations, operations or systems that include toxic or hazardous materials, high-power RF systems and laser systems, and a variety of other systems and operations. The details of the system design and its operation will determine whether the system or related operations are considered hazardous.
Accountability
Additional precautions will be determined during the safety approval process with SpaceX and the launch range. Ordnance operations, in particular, require coordination to provide reduced RF environments, cleared areas, safety support and other requirements.

Usability
User interface aesthetic
The standard mechanical interface between SpaceX-provided Falcon launch vehicle hardware and customer-provided hardware is a 1575-mm (62.01in.) diameter bolted interface, at the forward end of the launch vehicle payload attach fitting. This interface is designed to conform to the EELV1575-mm (62.01in.)diameter medium payload class mechanical interface defined in the EELV Standard Interface Specification Rev. CJune2017.For customers with 937-mmor 1194-mm(36.89 in. or 47.01 in.) For customers with alternative interface requirements, SpaceX can procure almost any industry-standard adapter system as a nonstandardservice. SpaceX has experience integrating numerous commercially available and internally developed adapters and separation systems.

Operability
clampband interface requirements, SpaceX will either provide and integrate a payload adapter and clampband separation system or will integrate an adapter and separation system chosen and provided by the customer, as a standard service.

Portability

Adaptability
SpaceX believes rocket reusability is the key breakthrough needed to reduce the cost of access to space and enable people to live on other planets.
Replaceability
SpaceX BFR is first orbital class rocket capable of reflight. SpaceX the first commercial company ever to visit the station.Raket has made numerous trips to space, delivering satellites to orbit as well as delivering and returning cargo from the space station for NASA
Reliability
Fault tolerance
The fault tolerance is achieved either by isolating compartments within avionics boxes or by using triplicated units of specific components. Both the first and second stages host their own multiple redundant lithium-ion batteries to minimize the complexity of the electrical interface
A study1by The Aerospace Corporationfoundthat 91% of known launchvehicle failuresin the previoustwo decades can be attributed to three causes: engine, avionicsand stage separationfailures. With this in mind, SpaceX incorporated key engine, avionics,and staging reliability features for high reliability at the architectural level of BFR launch vehicles.

Availability
The pneumatic system allows for acceptance and functional testing of the actual flight hardware, which is not possible with a traditional explosives-based separation system.For each Falcon launch vehicle, SpaceX performs an exhaustive series of tests from the component to the vehicle system level.
