The F-22 radar from Lot 5 aircraft onward is the APG-77(V)1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities. [5] In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1–11 test aircraft. The radar system had accumulated over 300 flight hours by 2010.
IMA concept also allows the Application developers to focus on the Application layer, reducing the risk of faults in the lower-level software layers. As modules often share an extensive part of their hardware and lower-level software architecture, maintenance of the modules is easier than with previous specific architectures.
The FAA Advisory Circular (AC) 20-170 [1] refers to DO-297. Along with ARINC 653 and DO-248, the DO-297 standard guides "Safety of flight for IMA systems" [2] DO-297 provides specific guidance for the stakeholders, defining the following roles [3] platform and module suppliers; application suppliers; IMA system; integrator; certification applicant

As Russian forces make slow progress in eastern Ukraine, Ukraine's military stages a surprise cross-border attack.
The AN-FPQ 6 radar was built by RCA and was, effectively, a development of the AN-FPS 16. The Q6, as it was known by those who worked on it, was an amplitude comparison monopulse C-band radar, with a 2.8 MW peak klystron transmitter tunable from 5.4 to 5.8 GHz, which had a 9-meter parabolic antenna, having 52 dB gain, a 0.6 degree beam width, utilizing a Cassegrainian feed with a five horn ...
Material flow analysis (MFA), also referred to as substance flow analysis (SFA), is an analytical method to quantify flows and stocks of materials or substances in a well-defined system. MFA is an important tool to study the bio-physical aspects of human activity on different spatial and temporal scales.
