AIR CHARTER – Act of renting or leasing a jet or plane for transport of cargo or passengers.

AIR CHARTER AGENT – One who is contracted on behalf of the end user of the charter flight. A charter agent works to ensure fair market value, reasonable safety measures are followed and to provide flexibility and options for the purchaser of the air charter flight.

AIR TRAFFIC CONTROLLER – The service to pilots that promotes the safe, orderly and expeditious flow of air traffic. Usually each country operates its own Air Traffic Control service. In the UK, Air Traffic Control services are provided by NATS.

AIRCRAFT – A machine used for flight which gains lift or support from the air.

Credits can be exchanged between businesses or bought and sold in international markets at the prevailing market price. Credits can be used to finance carbon reduction schemes between trading partners and around the world.

CARBON EMISSIONS – The principal greenhouse gas emission. Carbon is largely thought to be the most dangerous greenhouse gas.

CARBON OFFSET – Monetary contributions to renewable energy research and production projects, designed to reflect and mitigate the user’s own greenhouse gas emissions eg through air travel.

COMMERCIAL FLIGHT – A “commercial” flight is when the customer has paid for a commercial charter of that aircraft. The rules for commercial flights are more stringent than private flights and include limitations on crew duty hours, runway length and other safety considerations. For commercial private jet charter the minimum stopping distance for the aircraft is multiplied by 1.6, to create the minimum landing distance required (LDR).

If a passenger’s flights are operated by two different airlines, they may check baggage or obtain boarding passes for the entire itinerary directly at the departure city’s airport, pursuant to interlining agreements or airline alliances. A connection is not the same as a stopover.

DECISION HEIGHT – In an instrument approach flight, the height at which a decision must be made to either continue the approach or to execute a missed approach.

DEMURRAGE – Refers to the charges that are levied by an operator when a charterer keeps an aircraft after the completion of the flight. For example, if an aircraft is chartered for two flights with a week intervening, an aircraft may remain or lay over at the destination. The charterer will pay demurrage charges for every day that this aircraft remains at the charterer’s destination without returning home.

DENSITY ALTITUDE – Pressure altitude (as indicated by the altimeter) corrected for air temperature.

DEPRECIATION – Method to account for assets whose value decrease over time because of factors such as age, wear or market conditions.

DIRECT FLIGHT – A flight that operates from point A to point B without a connection. A direct flight is not necessarily non-stop.

DME – Distance-Measuring Equipment. A combination of ground and airborne equipment which gives a continuous slant range distance-from-station readout by measuring time-lapse of a signal transmitted by the aircraft to the station and responded back. DMEs can also provide groundspeed and time-to-station readouts by differentiation.

DOUBLE ROUND TRIP – Occurs when an air charter itinerary is designed such that it is more costly to keep the plane away from base than it would be to return home empty the report for pick up to complete the air charter itinerary.

DOWNWIND – One of the many words describing the approach segments.

DUTY TIME – A pilot or crew member is logging duty time whenever he is serving in any capacity. There are safety restrictions on duty time to ensure pilots and crew are sufficiently rested.

E

EMPTY LEGS – A re-positioning flight where the aircraft is flying empty. Chartering an empty leg can cost significantly less than a full-price charter.

EXECUTIVE JET CHARTER – An aircraft that is chartered for the purpose or use in the transportation of executives. Typically the aircrafts that are chartered are midsize jets.

F

FEATURED CHARTER – The chartering of a specific aircraft to a specific destination. Featured charters often include hotel accommodations, luxury car rentals, golf and spa packages etc.

FERRY FLIGHT – A flight for the purpose of returning an aircraft to base, delivering an aircraft from one location to another, moving an aircraft to and from a maintenance base.

Non-airline passenger flights fall in the broad General Aviation category, however the terms Business Aviation or Executive Aviation are frequently used to differentiate private jet charter flights from light aircraft enthusiast flights.

GO-AROUND – Balked approach, when the aircraft climbs away from the runway during the approach, to either start the approach again, or proceed to the ALTERNATE AIRPORT.

GREAT CIRCLE DISTANCE – The shortest distance between two points on a globe. All distances shown in distance tables in the Air Charter Guide are “great circle distance”.
