‘জুলুমকারী বা ক্ষমতার অপব্যবহারকারীদের সম্পর্কে তুমি কখনো মহান আল্লাহকে উদাসীন মনে করবে না’ (সূরা ইবরাহিম-৪২)।

জালিমকে তার জুলুম থেকে প্রতিহত করার ব্যাপারে রাসূল সা: কঠোর ভাষা ব্যবহার করেছেন, ‘মানুষ যদি কোনো অত্যাচারীকে অত্যাচারে লিপ্ত দেখেও তার দু’হাত চেপে ধরে তাকে প্রতিহত না করে তবে আল্লাহ তায়ালা শিগগিরই তাদের সবাইকে তাঁর ব্যাপক শাস্তিতে নিক্ষিপ্ত করবেন’ (সুনানে তিরমিজি-২১৬৮)।

কুরআনের ঘোষণা, ‘অবশ্যই আমি তোমাদের আগে বহু জাতিকে ধ্বংস করে দিয়েছি যখন তারা জুলুমে লিপ্ত ছিল’ (সূরা ইউনুস ১০-১৩)। রাসূলুল্লাহ সা: বলেছেন, ‘নিশ্চয়ই আল্লাহ তায়ালা অত্যাচারীকে অবকাশ দিয়ে থাকেন। অবশেষে তাকে এমনভাবে পাকড়াও করেন যে, সে আর ছুটে যেতে পারে না’ (বায়হাকি-৬/৯৪; বুখারি-৪৬৮৬; মুসলিম-২৫৮৩)।

The Feasibility Of Employing Fly-By-Wireless In Future Generations Of Commercial Aircraft?

=> The fly-by wireless system is an innovation created by the aviation industry has more efficient and feasible for commercial aircraft. This system has a few positive impacts such as weight reduction, easy maintenance, more redundancy, and also easier retrofitting. It's a really broad area and it can cover a few types of avionics and communication technologies.
Wireless solutions can not only reduce an aircraft's weight but also reduce the costs associated with the overall life cycle of the aircraft. In addition to reducing hours spent troubleshooting wires and connectors due to the elimination of many key failure points, the problem of wires and connectors will also be reduced. Further, engineering costs may diminish through the reduction in time spent to design wiring installations, the ability to easily make late changes to a design of an aircraft, and many other efficiencies.

»» Liquid Fuel or Electric Power????

✔Compared to a piston engine the electric motor has advantages: It is small, and contains no reciprocating but only rotating parts.
✔ The main challenge of electrical flight is where and how to store the required electrical energy for the entire flight!!
✔ An electric Powered aircraft needs to store energy in its batteries and will be a large part of the total aircraft weight.

Fly-by-Wireless (FBWSS):
Research Areas and Activities

Typically, air traffic control (ATC) is the task of air traffic controllers stationed on the ground that provides flight guidance for aircraft on the ground and through controlled airspace, as well as providing advisory services for aircraft in non-controlled airspace. The primary reason for the existence of air traffic control (ATC) worldwide is to prevent collisions, to organize and expedite air traffic flow and to provide information and other support to pilots. The Air Traffic Control system is used by the military or the military's security or defense forces in some countries.

Propulsion Systems:
Propulsion engineers will continue to be required to conceive, design, and build propulsion systems of a wide variety of sizes and attributes, as seen by the preceding assessment of prospective aircraft needs during the next fifty years. Fortunately, gas turbine-based propulsion systems come in a variety of shapes and sizes, with a variety of thermodynamic cycles and mechanical configurations. Pressures for substantial increases in energy efficiency and pollutant emissions, for example, might be interpreted as supporting concepts that have the potential of making relatively major step-changes in these areas.

Electric air taxis: With several start-ups and aircraft manufacturers working on solutions for urban air transportation, electric air taxis are becoming a reality. Later, for certification flights, a manned prototype will be employed.
