The two corporations aren’t directly buying fuel from World Energy. Instead, they’ll purchase certificates representing SAF that gets pumped into the larger supply chain — then count the associated carbon reductions toward their sustainability goals. Microsoft agreed to buy certificates representing 43.7 million gallons of SAF over a 10-year period, while DHL signed a contract for 177 million gallons over seven years.

one   of the first I learned to spot was the Boeing 737.  It's the best selling commercial aircraft of all   time, it's everywhere. Once you know the trick,  it's incredibly easy to identify in the air.   It has no doors over the landing gear, if it's too  big to be a regional, it's a 737. You can see how   the gears swing out from the wheel shaped  cavities in the center of the fuselage.

The system of card indexing was propagated by a French Person called Abb’e Jean Rozier (1734-93). The index is prepared by allotting a separate card to each piece of information. The required information are written on the cards. All cards are of uniform size and are arranged in alphabetical, numerical or geographical order.

aviation experts haddevised a solution to the problem of pilot interruption: the “sterile cockpit rule.”Instituted by the Federal Aviation Administration in 1981, the rule forbids pilotsfrom engaging in conversation unrelated to the immediate business of flyingwhen the plane is below ten thousand feet.

an accident in which there is a collision with terrain, water, or obstacle during the course of a flight, without indication of loss of control.

NVESD researches, develops, tests and evaluates electro-optic/infrared (EO/IR) sensor technologies for airborne and ground-based reconnaissance and targeting under all battlefield conditions. NVESD also expands tactical use of laser designators and markers for precision engagement, day or night, while maintaining the capability to maneuver.

Army 12th Aviation Battalion uses helicopters to maintain readiness for consequence management missions, such as defense support for civil authorities or homeland security operations, and to provide transportation. To conduct these flights, the Army uses 34 Sikorsky UH-60 helicopters stationed at Davison Army Airfield in Fort Belvoir, Virginia.

Davison Army Airfield (DAAF) located on Fort Belvoir, Virginia. DAAF is home to the Army’s 12th Aviation Battalion, which is the primary operator at the airfield, along with the District of Columbia Army National Guard and the Night Vision and Electronic Sensors Directorate. There are various aircraft stationed at DAAF including UH-60 Blackhawk and UH-72 Lakota helicopters, which are used for missions such as consequence management readiness, defense support for civil authorities, homeland security operations, air medical operations, and transportation.

DAAF personnel reported 13,272 departure and arrival operations, not including closed pattern work (take-off and landing practice) at the airfield, in Calendar Year (CY) 2020 with over 98 percent occurring during acoustical daytime hours—7:00 a.m. to 10:00 p.m. This is the highest yearly total in the past four years.

12th Aviation Battalion conducts air movement and engineer technical rescue operations for senior leaders of the Army, Department of Defense, and United States Government, while maintaining a continuous alert posture in support of the Joint Force Headquarters National Capital Region in order to sustain a rapid response, readiness, and support force capability.

Global air traffic is expected to double to 8.2 billion passengers in 2037, according to IATA, which predicts that aviation's 2019 emissions peak of around 900 million metric tons of CO2 will be exceeded within the next two to three years.At the same time, the window to cut the world's reliance on fossil fuels and avoid catastrophic changes to the climate is closing rapidly. The International Energy Agency forecasts that aviation's share of global carbon emissions will increase to 3.5% by 2030 from just over 2.5% in 2019 in the absence of efforts to further decarbonize.

The E-Fan X hybrid-electric technology demonstrator is anticipated to fly in 2020 following a comprehensive ground test campaign, provisionally on a BAe 146 flying testbed, with one of the aircraft’s four gas turbine engines replaced by a two megawatt electric motor. Provisions will be made to replace a second gas turbine with an electric motor once system maturity has been proven.
