The aviation community does not change things unless they absolutely have to because unnecessary change kills people. Aircraft instruments have always been marked in feet. If they changed to metric just because metric is More Modern, eventually an ATC somewhere would call out a metric altitude, a plane would think it was in feet and fly there, and wind up getting into a mid-air accident with a General Aviation plane. Feet work fine in aviation, so they'll keep using feet.
Business Aviation is the use of any general aviation aircraft for a business purpose. The Federal Aviation Administration defines general aviation aircraft as all flights that are not conducted by the military or scheduled airlines.
Aviation technology.
Aviation fuel
Aviation is the design, development, production, operation, and use of aircraft, especially heavier-than-air aircraft.
Planes typically use aviation fuel, which is a specialized type of fuel designed for aircraft engines. The most common type of aviation fuel is known as Jet A or Jet A1, which is kerosene-based. Some small aircraft may use aviation gasoline (avgas) instead.
most commercial airplanes use aviation fuel however some smaller planes may use a more concentrated version of aviation fuel
The Wright Brothers made aviation possible. The recent successful landing of a plane on the Hudson River is a miraculous event that well forever be part of aviation history. Aviation refers to activities involving aircraft, and it includes the people, organizations, and regulatory bodies involved with them.

Cessna aircraft typically fly at altitudes ranging from 3,000 to 10,000 feet for general aviation purposes, depending on the model and mission. For instance, the popular Cessna 172 often operates around 5,000 to 7,000 feet during training flights. However, some Cessna models, like the Citation series, can cruise at altitudes of 30,000 feet or higher for business aviation.
Airplanes do use fuel, called aviation fuel. When crude oil is processed thro distillation process , first to come out is grades of diesel, then kerosene, then petrol. After distillation, what remains is tar etc. Aviation fuel is similar to diesel, that is, petrol is more pure than aviation fuel..
Either aviation gasoline or Jet A.
