Routes over Italy ( east, west v.v. )

Post by jeen » Sun Dec 18, 2016 7:48 pm

hello,

What happend with the high routes over Italy? A lot of routes needs a modify with the current AIRAC cycle. I saw the new high route and low route charts and noticed that the U is missing in most airways ( UM730 become M730 ) so only low airway routes over Italy. When leaving Italy you can connect the high airway via an intersection and then you can climb to higher levels. Are I missing something here. Why changed the LOW and HIGH routing airways over this area? Do you guys now? With this change of airac and change of airways you have to change and modify all the routings starting the new routings with /NO...F.... etc. To get a go for a new route in Vroute is now a time consuming job. And it is strange that when you departure from LFML/LFLL etc that yo fly 300NM over Italy at low airways and after leaving Italy climb to higher Levels. Hope you guys can tell me more about this change.

kind regards Jeen.

Hi Jeen ,
yes, something has happened in Italy.
Since December 8, 2016 ENAV introduced FRAIT "Free Routes Airspace Italy" above FL335.
Here you can find some explanations:

Kind regards, Claudio

This is a simple english translation of the first doc: http://aeronauticalinformation.it/index ... ory/airac/.
I'm sorry for mistakes.
Enjoy

Turning point for Italians airspaces: Frait (Free Route Airspace Italy) is coming.

The deliberation was announced by the Aeronautical Information Circular A11 / 16, and is operative since 8 December 2016, with the AIRAC A11 / 16.

In essence, in the airspace Frait, pilots should plan direct routes (DCT) between a defined entry point and a defined exit point, it is possible to use defined intermediate points, without any reference to the ATS route system (which It is, in fact, abolished in the FRAIT interior), depending on the availability of airspace.

All this is to ensure efficiency, reliability and environmental sustainability of the entire system.

It is a single zone, usable H24 and classified "C", having, as its lateral limits, all the areas of responsibility of the Italian ACC (Milan, Padua, Rome and Brindisi) and, as vertical limits, the space between the flight level 335 and flight level 660.

Inside the FRAIT space the cruising levels are organized in compliance with the provisions in the table of cruise levels contained in Annex 2 ICAO, Appendix 3, a).
In order to meet the predominant roads, apply the following changes relative to the route:
- "From 090 to 269 degrees" instead of "000 to 179 degrees";
- "270 to 089 degrees" instead of "180 to 359 degrees"

Furthermore:
1. In the planning phase, no restriction is applied with regard to the maximum direct distance between waypoints within the Frait.

2. In airspace Frait, the inclusion of direct segments (DCT) is allowed in the flight plan. These segments must be inside the limits of airspace Frait.

3. It is not allowed to plan DCT segments at a distance of 2.5 NM or less from the border that separates the competency limit of two providers of air navigation services.
Note: This limit was 5NM in AIC A11/16, but was lowered to 2.5NM in AIP pages

4. you can schedule flights that pass through the "AMC manageable" areas, however, if some portions of airspace should not be available, it would be necessary to use intermediate points to circumnavigate the restricted area.

5. To allow connection between the airspace Frait and the ATS route network, expected to land on the Milan/Linate (LIML), Milan/Malpensa (LIMC), Bergamo/Orio al Serio (LIME), Rome/Ciampino (LIRA), Rome/Fiumicino (LIRF) and Venice/Tessera (LIPZ), have been defined the trajectories (Transition Routing).
These trajectories (Transition Routing) are identified by two mandatory intermediate points (Compulsory Intermediate): the first has to be planned to above FL 335 (inside the Frait space), while the second below FL335, to connect to the conventional network of ATS routes.
The Transition Routing are implemented by defining restrictions RAD (Route Availability Document).

6. In order to avoid short crossing of many different ACC’s airspaces, two zones are defined, within which it is not allowed to plan trajectories (No Planning Zone - NPZ); pilots must then avoid those areas, planning appropriate Intermediates points, that are published in AIP Italy ENR 4.1.1. and 4.4
The connection between the Frait and the ATS routes network, located below flight level 335, will be ensured through the use of specific points Intermediates (Compulsory Intermediate Point) which must be scheduled before/after the Entry/Exit point matching (see also:https://www.nm.eurocontrol.int/RAD/index.html).

Thanks Arp624. Now Its difficult to make a new route over Italy because there are only low airways. When you want to fly higher airways and file a new route to Vroute over Italy you can only use the low airway because there is no high airway anymore. How can you build a high routing flightplan now when you depart from an Italian airport are an airport close to the border of Italy?

kind regards Jeen

Yes, is difficult. Only now I become able to plan a flight above the FL335 and totally inside the italian airspace.
This is an example betwen FL280 and FL400 (however Vroute not accept this route):

Is important that you observe that the lower airways are now extended up to FL335 (see the attach).

I fixed vroute's database a few days ago - the upper limits of low airways are now set properly and most validation errors should be gone by now.

I updated most LI** to/from EDDM/EDDS/EDDN/EDDP routes. Maybe you can use segments of theses routes. It is working now with vroute.
Within the airway system up to FL 330. Higher is DCT mandatory.
It is very time consuming to update the routes because mass edit isn´t possible.

Pls explain what change I need to make and I'll see if can do it automatically

I try an example:

Old route from EDDL to LIBD ....ELMEM UN606 GIRIS UZ905 VIC UN503 CHI UL612 VIE T415 EKMUR FL265-FL455 or something like that.
New route: ... ELMEM UN606 GIRIS DCT SUMIR DCT RUPAX L612 VIE T415 EKMUR FL355-FL455

You have to change the altitude and the route. That isn´t possible with the mass change.

Or you steel every airway in Italy the U then you have a route up to FL335.
But I think most jet aircraft are able to fly above FL335. So I prefer high routes.

Next I go to private routes and look what is outdated from ED** to LIBD. If I find a route which includes UN606... I change that route with copy&paste too.

If I automatically capped all non-DCT routes through Italy at FL335, would that help?

That would help if you cut the U from the Italian airways in that moment. I think you will get many routes validated.
But then we still don´t have upper routes.

The Italian Free Route Airspace is a little different to other countries. In most cases you are unable to fly DCT to the STAR point (viceversa with the SID). On the descend path <FL335 you have to switch back to the airway system. Many routes look like this: ...DCT MOMOD DCT NIKMA T369 RITEB LIRF. First DCT then airway.

Just try it with the outdated routes. :lol:
It isn´t easy because on a route from the north to LIME eg ...DOSEL UM736 NAXAV UM984 LUSIL LIME you have to insert the border point OLPIX. ......DOSEL UM736 OLPIX M736 NAXAV M984 LUSIL LIME

In some cases to northern Italian airports cfmu accepts routes above FL335 within the airway system because the calculated descend profile is below FL335 at the border.

892 routes fixed by adjusting max FL and/or removing Us from airway names.

This is just to/from LIxx, I'll rerun the process now to include transits too.
