A flight that has left the departure gate but may not be airborne yet
When a flight's status is listed as "departed", it means that the flight has left the departure gate but may not be airborne yet. The takeoff time is the actual takeoff or "wheels up" time. The arrival time, however, is still an estimate.
The status "departed" is different from "in air", which means the flight is airborne. Similarly, "landed" means that the flight has landed, but it may not have yet arrived at its gate. The "arrived" status signifies that the flight has reached its gate at the destination airport.
Other flight statuses include "expected", which means the flight is expected to arrive at the destination airport, with an estimated arrival time usually available. "Diverted" means the flight has been diverted from its original destination to a different location. "Recovery" indicates that the flight has departed the diverted location and is en route or has landed at the scheduled destination.
The status "cancelled" means the flight has been cancelled, while "no takeoff info" means that the real-time status of the flight is unavailable. This could be due to a delay, cancellation, or unavailability of real-time status for international flights.

Permission to depart, or clearance, is required prior to departure
When an aircraft is preparing for departure, it must obtain permission to depart or clearance before it can leave the airport. This process involves coordinating with air traffic control (ATC) and adhering to various regulations and procedures to ensure safe and efficient operations. Here are the key aspects of obtaining permission to depart:
Clearance Delivery:
Pilots operating on Instrument Flight Rules (IFR) flight plans are required to communicate with the control tower prior to engine start. They must receive essential information, including engine start time, taxi instructions, and clearance details. This initial coordination is crucial for the aircraft's subsequent movements.
Line Up and Wait (LUAW):
LUAW is an ATC procedure that guides an aircraft onto the runway in preparation for departure. While LUAW instructs the pilot to taxi, align, and await further instructions, it does not authorize takeoff. Pilots must be cautious and not confuse LUAW with a departure clearance, as taking off without the necessary clearance could lead to catastrophic consequences.
Clearance Amendments:
Prior to departure, controllers may need to amend the filed route or altitude for an aircraft. In such cases, they will specify any necessary changes, including the assigned departure routing, altitude restrictions, and additional instructions to ensure a safe departure. Controllers must be meticulous in communicating these amendments to avoid any confusion.
Clearance Void Times:
Clearances typically include a void time, which is the deadline by which an aircraft must take off. If an aircraft misses its clearance void time, the pilot must promptly notify ATC of their intentions. Failure to contact ATC within 30 minutes after the clearance void time will trigger search and rescue procedures, as the aircraft will be considered overdue.
Customs Clearance:
Aircraft carrying merchandise or passengers across international borders must obtain customs clearance. This process involves requesting clearance at the Customs port of entry or the nearest international airport. The aircraft commander or agent is responsible for ensuring that the necessary clearances are obtained, adhering to regulations set by authorities like the Bureau of Industry and Security and the Department of State.
In summary, obtaining permission to depart or clearance is a critical aspect of airport operations. It involves a range of procedures and considerations, from initial communications with ATC to adhering to clearance void times and complying with customs regulations. By following these protocols, pilots and air traffic controllers work together to ensure the safe and efficient departure of aircraft from airports worldwide.

CBP Agriculture Specialists must be contacted before moving aircraft from the US Virgin Islands to other US locations
In an airport context, 'departed' means that a flight has left the departure gate but may not yet be airborne.
The US Customs and Border Protection (CBP) has implemented specific procedures for aircraft departing from the US Virgin Islands (USVI) to other destinations within the United States. Before an aircraft can depart from the USVI to another US location, it is mandatory to contact CBP Agriculture Specialists (CBPAS) in advance. This requirement is part of the CBP's security measures and inspection processes.
The CBPAS play a crucial role in ensuring the safe movement of aircraft from the USVI to other parts of the United States. Their involvement includes inspecting the aircraft, screening travellers and their luggage, and obtaining necessary declarations. This process helps to secure US borders and protect the country from potential threats, such as contraband or unsafe agricultural products.
To comply with these regulations, aircraft operators must provide CBPAS with a minimum of two hours' notice before their scheduled departure time. This advance notification allows CBPAS to conduct thorough inspections and ensure that all necessary documentation is in order. Failure to report or comply with CBP requirements can result in significant civil penalties, as outlined in the United States Code.
It is important to note that the CBP has implemented a local pilot program, the Virgin Islands Air Passenger Pilot Program, which specifically addresses departures from USVI airports to domestic US destinations. As part of this program, CBP officers and CBPAS work together to obtain binding oral declarations from passengers, which include information about their trip origins and countries visited. This additional layer of security further enhances the efficiency and thoroughness of the inspection process.

The arrival time of a flight is estimated
When a flight has 'departed', it has left the departure gate but may not yet be in the air. The arrival time of a flight is an estimate, and it can be a challenging metric to get right. Several factors can impact a flight's arrival time, and delays are common. The published arrival time is not just the time spent in the air but also includes taxiing, boarding, and deplaning. It is challenging to time flights to the minute, and delays can occur due to slow boarding, bad weather, or heavy traffic. As a result, arrival times are often estimated conservatively to allow for delays.
The U.S. Department of Transportation (DOT) considers any flight that arrives within 15 minutes of its scheduled time to be "on time". This leeway helps airlines avoid sanctions and provides a more realistic expectation for passengers. However, this also means that passengers should expect some delays and plan accordingly.
To formulate flight times, airlines use complex methods that incorporate various data points. They analyse previous performance within the National Airspace System and consider factors such as average taxi time, en-route time, and chronic air traffic delays. This data helps them estimate flight times accurately and keep operations running smoothly.
While airlines want to provide accurate arrival time estimates, they also have a financial incentive to be as efficient as possible. Reducing block time, even by a few minutes, can result in significant cost savings for airlines. Therefore, they invest significant resources into operational analysis to optimise their flight schedules.
In conclusion, the arrival time of a flight is an estimate that takes into account various factors and potential delays. Airlines use complex methods to formulate these estimates, aiming to balance accuracy, efficiency, and smooth operations. By considering the arrival time as an estimate and allowing for some flexibility, passengers can better manage their expectations and make appropriate travel plans.

Diverted means a flight has been diverted from its original destination
When a flight is diverted, it means that it has been rerouted to a different airport than the one it was originally supposed to land at. This can be due to various reasons, such as severe weather at the original destination, mechanical issues with the plane, or a medical emergency on board. In some cases, a plane may need to make an unexpected landing at the nearest airport due to a lack of fuel or passenger disruption.
During a diversion, the crew must advise the relevant people, including the cabin crew, passengers, air traffic control, and the company. They will provide a NITS briefing, which includes information about the nature of the problem, their intentions, the time available, and any special instructions.
As a passenger, it is important to remain in the gate area to receive any announcements regarding the diversion. If you have access to a gate and can enter the terminal, it is advisable to do so, as it may be more comfortable than remaining on the plane. However, it is important not to wander too far, as you don't want to miss any important updates or be left behind if the plane is cleared to continue its journey.
While waiting for the issue to be resolved, passengers can consider alternative transportation options to reach their final destination, especially if diverted to an airport relatively close by. It is also worth checking the travel benefits associated with the credit card used to book the flight, as some protections may be applicable in diversion situations.
In terms of compensation, airlines typically have provisions in their contracts of carriage to get passengers to their original destination, either by rebooking them on another flight or arranging alternative transportation. However, accommodations, meals, and other expenses may not always be covered, especially if the diversion was due to unforeseen circumstances beyond the airline's control.
