DMAN Baseline for integrated AMAN DMAN

Available for deployment

Waiting in a queue for take-off burns unnecessary fuel, generates delay and unpredictability and is frustrating for passengers. Fortunately, we encounter these queues less and less, due to a large extent to the way the departure management process is transforming departure time from an informed estimate into a precise art.

The departure manager (DMAN) tool takes into account the scheduled departure times, slot constraints, runway constraints and airport factors. In doing so, it improves traffic predictability, cost efficiency and environmental sustainability, as well as safety. By taking into consideration information such as the aircraft’s readiness to leave its parking stand, runway capacity and slot constraints, tower controllers can optimise the pre-departure sequence.

In order to calculate reliable sequences, DMAN needs access to accurate information about the status of individual flights and airport resources from different systems. The airport collaborative decision-making (A-CDM) platform supports this information exchange. For example, the airline or ground handler can provide the target off-block time (TOBT), while the tower controller uses tables which generate variable taxi times to achieve the target take-off time (TTOT). Information about departure slots or calculated take-off times (CTOTs) is sourced from the Network Manager, responsible for flow control across the whole of Europe.

Waiting in a queue for take-off burns unnecessary fuel, generates delay and unpredictability and is frustrating for passengers.

The use of a simple airport departure data entry panel (ADDEP) provides a lowcost solution to compute and share aircraft electronic pre-departure data across the air traffic management network, between the tower and approach controllers, as well a

SESAR’s time-based separation (TBS) replaces current distance separations with time intervals in order to adapt to weather conditions.

Small or local airports are a life-line for a local economy, however they cannot always afford to operate a control tower around the clock.

This solution develops further ADS-B applications to improve ground surveillance systems in terms of safety, performance, interoperability and security.

Remotely provided Air Traffic services for two low density aerodromes (small Size). Aerodrome Control Service or Aerodrome Flight Information Service for two low-density aerodromes is provided by a single ATCO/AFISO from a remote location, i.e. not from a control tower local to any of the aerodromes. The ATCO (or AFISO) in this facility performs the remote ATS for the concerned aerodromes.
Pre-Departure management has the objective of delivering an optimal traffic flow to the runway.

Knowing exactly when an aircraft is due to arrive has a direct impact on airport efficiency, especially if arrivals and departures are handled on the same runway, or on dependent runways.

For more than 50 years airports have relied on instrument landing systems (ILS) to provide pilots with approach and landing guidance in low-visibility conditions, such as heavy rain and low cloud.

This solution offers services to steer, monitor, manage airport performance as well as perform post-operations analysis. The solution also provides processes and tools to ensure airport performance in normal, adverse and exceptional operating conditions. An increased scope and timescale of data is shared between AOP and NOP.

Runway status lights (RWSL) include three types of high intensity LED lights: runway entrance lights (RELs), warning an aircraft about to enter the runway from a taxiway that the runway is not safe to enter, take-off hold lights (THLs) warning pil

As part of advanced surface movement guidance and control systems (A-SMGCS) activities, new generation automation systems have been included in validations to see how various tools can operate together to provide integrated airport safety nets.

Driving an airfield vehicle on the airport should be straightforward in normal operational conditions. But how do you ensure you are following the correct route when in dense fog, or at night, or when an unforeseen event occurs?

Conventional control towers are expensive to operate and maintain, and even at a medium-sized airport can become too costly if the number of flights is insufficient to cover the running costs.

Security alerts can shut down control towers. How does the airport ensure minimum disruption in an emergency? This question has been addressed by SESAR looking at contingency situations for airports.

Selecting the most suitable route from the departure gate to the runway or from the runway to the gate depends on the airport layout, aircraft type, operational constraints such as closed taxiways, arrival routes, as well as departure planning inf

Radio channels become congested and hard to access during periods of busy traffic.

This solution improves the safety of surface operations, especially during low-visibility conditions, through a reduction of runway incursions, taxi route deviations and holding position overruns.

Supporting controllers and flight crew is especially important in low-visibility conditions. A line of red lights, known as stop bars, are already used to prevent aircraft entering a runway without air traffic control clearance.

The solution increases the accuracy of information related to when the procedure is going to take place, how long it will take and when the aircraft will be ready to taxi for departure, which is currently calculated by predetermined estimates.
