| General Aviation | One of the two categories of civil aviation. Private flights are in this category. It refers to all flights other than military and scheduled airline and regular cargo flights, both private and commercial. General aviation flights range from gliders and powered parachutes to large, non-scheduled cargo jet flights. The majority of the world's air traffic falls into this category, and most of the world's airports serve general aviation exclusively. |
| Glider | An unpowered fixed-wing heavier-than-air craft. (See also sailplane) |
| Global Positioning System (GPS) | A space-based global navigation satellite system that provides reliable positioning, velocity, and time information in all weather and at all times and anywhere on or near the Earth there is an unobstructed line of sight to four or more GPS satellites. Highly accurate navigation aid. |
| Gravity | The natural force of attraction exerted by a celestial body, such as Earth, upon objects at or near its surface, tending to draw them toward the center of the body. One of the forces of flight. |
| Great Circle Distance | The shortest distance between two points on a globe. |
| Green Aircraft | A green aircraft from the OEM is literally green on the outside from being coated with oxidized paint, and is completely empty down to the interior cabin belt frames. It is a completed flyable airframe, but certainly nothing the customer will ever be able to use or place into service for themselves until the interior has been designed, engineered, installed and completely certified with a fresh Certificate of Airworthiness. |
| Greenwich Mean Time (GMT) | Mean solar time at the village of Greenwich near London which, as decided at the International Meridian Congress of 1884, is assigned 0 degrees longitude (called Prime Meridian). Because it is based on the Earth's rotation (which is irregular) it actually follows a fictitious Mean Sun that moves at a uniform speed along the equator. A 19th century worldwide time standard, it was replaced in 1970 by the Coordinated Universal Time (UTC) for astronomical and navigational use, but is still in common use by airlines and radio and television stations. When expressed in terms of a 24-hour clock, GMT is also called universal time (UT or Z). It is five hours ahead of the US Eastern Standard Time (EST) during standard period, and four hours ahead during daylight-saving period. |
| Ground Speed | The speed of an aircraft's shadow as it travels over the ground. If you have a strong tailwind, it will be faster than the actual airspeed measured in the cockpit. |
| Ground Transportation | A service provided for luxury jet charters before or after a flight. Ground transportation can be limo service or luxury car rental. |
| Grounded | Term used to describe an aircraft that is not allowed to fly for whatever reason- ranging from mechanical issues and inspections to bad weather and volcanic ash clouds. |
| Guaranteed Hours | The number of hours of flight time a flyer will commit to purchase when leasing an aircraft or buying block hours. If the flyer utilizes the aircraft for fewer hours in the stated time period, they will still be obligated to pay for the guaranteed hours. |
