What is TMI Nat track?
Track Message Identification (TMI) NAT Track Structure Messages are identified by a 3-digit Track Message Identification number (TMI) appearing at the end of the Track Message. • This number relates to the day of the year (no reference to month).
How many NAT tracks are there?
The OTS is an invisible multi-lane motorway that connects Europe and North America. Each day up to twelve tracks are created west and eastbound, designed to take advantage of the day’s Jet Stream and give the airlines an efficient route across the ocean.
How far apart are Nat tracks?
RLAT reduces the standard distance between NAT tracks from 60 to 30 nautical miles (69 to 35 mi; 111 to 56 km), or from one whole degree of latitude to a half degree. This allows more traffic to operate on the most efficient routes, reducing fuel cost.
What is TMI in aviation?
Acronym for “Traffic Management Initiative.” TMIs are tools that air traffic managers use to manage either enroute or terminal air traffic. TMIs consist of GDPs, ground stops, AFP, TBFM, reroutes, etc.
What are Blue Spruce routes?
Additionally, within the HLA, special routes, referred to as “Blue Spruce Routes”, have been designated for aircraft equipped with only one LRNS plus normal short-range navigation equipment (VOR, DME, ADF), which require to cross the North Atlantic between Europe and North America (or vice versa).
Do planes fly over north Atlantic Ocean?
The organised track structure. With more than 1,000 flights crossing the Atlantic Ocean each night from North America to Europe, it’s one of the busiest airspaces in the world.
Can you track transatlantic flights?
For many flights over the North Atlantic we receive real-time North American radar data that allow us to track a flight all the way across the ocean.
Is there ATC over the Atlantic?
The researchers projected that using this approach, airliners would reduce the amount of carbon dioxide emitted by 6.7 million tons in a typical winter. Since March, ATC has been testing the new system over the Atlantic.
What time are Nat tracks published?
Typically, the time of publication of the daytime (westbound) OTS is 2200 UTC and of the night-time (eastbound) OTS is 1400 UTC. The NAT Track Message gives full details of the co-ordinates of each track of the OTS as well as the flight levels that are expected to be in use on each of those tracks.
What is TMU in aviation?
Acronym for “Traffic Management Unit.” A TMU is a team of air traffic managers inside of each enroute center (ARTCC) that focuses on traffic flow management processes (as opposed to separating traffic) and coordinates directly with the Command Center.
What is MRD on a plane?
Maximum Recoverable Delay (MRD) and Actual Recovered Delay (ARD) for Each Flight in a Scenario. Source publication. Flexibility Metrics and Their Application to Departure Queue Management.
Do you need state approval prior to flying blue spruce routes?
As these routes are within NAT HLA Airspace, State approval must be obtained prior to flying along them.
