[26th April 2025] Cross The Pond Westbound- Discussion Thread

Cross The Pond - Westbound 2025

Welcome to the discussion thread for CTP Westbound 2025!

We are pleased to return for another Cross the Pond, this time following the fun westbound on April 26th, 2025.

Cross The Pond is the largest and longest-running event on VATSIM (over 20 years). The event is biannual flying between the two sides of the Atlantic Ocean - Westbound in the spring and Eastbound in the autumn. Hundreds of pilots light up the virtual skies, and dozens of controllers burn both ends of the candle to provide professional ATC service over the Ocean and the Continents.

Our teams of volunteers are already working in the background for this next edition, so we will be posting updates soon!

To keep in touch with news regarding the event, you can follow us on our social media and look for the hashtag #CTP25W

We also have a dedicated discord server, which is going to get busier as we approach show-day. To join us, head over to https://ctp.vatsim.net/discord and follow the instructions on your screen.

We are pleased to announce that the airport voting for Cross the Pond Westbound 2025 has now opened. VATSIM members can vote for their top airports the end of Friday, 14MAR25 via the CTP website .

Members can vote for their 1st, 2nd and 3rd favourite choice on either side of the ocean, earning that airport 5, 3 and 2 points respectively. The Planning Team of the event will then meet with the user’s vote to include your favourite airports and occasionally a choice of their own.

A complete list of the airports available on each side of the ocean is listed at the end of my post.

On behalf of the Planning Team, good luck to all the airports!

Pilots are now allowed to join our slot lottery!

Demand for participation in CTP outweighs the available capacity of the controllers and airspace. As a result, we chose to limit the number of participants using a slot system.

Only pilots with a slot are able to participate in the event. In order to distribute the slots to pilots we complete the following steps:

  • Pilots register their interest (available until 10APR24 2359z)
  • Everyone who enters the lottery will get a personalised booking time
  • Pilots login after their allocated time and pick a time slot and city pair (being earlier in the lottery gives more chance for the route you want) (available 13APR24 through 18APR24)
  • Pilots who have booked via the above MUST return to the CTP website and confirm their bookings between 20APR24 and 23APR24 2359z. If you do not do this, you WILL LOSE YOUR SLOT.
  • After everyone has had some time to select their route, the remaining slots are released to all members (24APR24, ~1700z).

Several factors affect the outcome of the lottery, the most significant of which is your historical interaction with this event. If you have no-showed during a previous event when you held a booking, you will have slightly less chance of getting a slot now. If you applied but did not get a slot last year, you will have a slightly higher chance of getting a slot now.

As in previous events, you will have to return to the website in the week leading up to the event to reconfirm your intention to fly and to provide important information such as your callsign, maximum assignable flight level and so on.

You may now register to be included in the lottery at ctp.vatsim.net.

======================================================================

This Event’s system in Detail

The lottery will run much the same as previous - that being that everyone will go into the lottery and get randomised into an order. This order will be affected primarily by chance, however, there will be weighting for the following:

  • No shows - negative weighting if you no-showed a slot you had in the previous event. This does not include people who dropped a slot they were allocated.
  • Previous slot allocations - if you got a slot in the last lottery, you have a slightly negative weighting. Likewise, if you didn’t, you have a slight positive weighting
  • Sequential events - if you have multiple sequential unsuccessful events, you get more of a positive weighting

With all of those factors taken into account, people will be ranked from 1 to N (N being the total number of people who express interest). A reminder that the main factor is chance, and therefore if you have negative weighting, you aren’t guaranteed to not have a later booking time. Likewise, with a positive weighting, you aren’t guaranteed an early one.

Each person is then given a time that they can book from and there is at least 1 minute between each person in the lottery, therefore a maximum of 5 people get in every 5 minutes. We try to base the booking times so that members from around the globe would be able to log in near to them without much hassle. The point of this is that if you can’t exactly make whatever time you’re given, you are likely to be able to log on soon after and still get a choice of slots, in contrast to the classic ‘free for all’ system where being 15 minutes late meant no slot at all.

We’re not sure how popular all the slots will be, therefore it’s perfectly possible that we’ll run out of slots before the last booking times and therefore people towards the end of the lottery may not have any slots left to choose from. Equally, it’s perfectly possible that some slots and times that are less popular will still be available. People with slots can drop them at any time, so slots will always pop up.

Everyone will then have to return to the site between 13APR24 and 23APR24 (0000-2359 UTC) to confirm they are flying and ensure they’ve filled in all the details. If you don’t do this, your slot will become available to anyone else to take.

Regardless of what’s left, anything not taken will be available on 24APR24. Anyone at this point can take a slot from what’s left. Anything dropped will be available to be booked.

Pilot Briefing Seminar

Something that is not new, but regardless, not talked enough about is the Pilot Briefing Seminar. Our friends from the Flight Simulation Association and other known members of the community are running a seminar to help new and experienced pilots prepare for the event and bring them up to speed with anything new from oceanic procedures, to departing and arriving in the respective continents (with all the differences between FAA, EASA and other airspace).

We will be sharing more details on the seminar very soon, so watch this space, as well as our Discord and our social media accounts on Facebook and X/Twitter @vatsimctp

I just worked myself through the briefing documents and noticed something:
CTP still requires Oceanic Clearances for Shanwick and Gander.
Personally I’m not affected by this as I won’t be flying through those sectors, but I noticed that this is a deviation from real world procedures.
In the real world both Shanwick and Gander stopped using them on December 4th last year. I was just curious why VATSIM did not adopt the discontinuation?

Cross the Pond 2025 - Westbound - Non-Event Traffic

Today we will host more than 1,300 planes across the Atlantic to a range of airfields across Europe and Africa, from departing fields in North and South America. In designing this event, the majority of our ATC capacity is assigned to pre-booked traffic for our event.

Because of this and the huge amount of work that goes into providing service for these planes, we ask you not to fly across the ocean at all. We also ask you not to utilise the event fields during the peak window as there are many other flight options available.

The rest of this post details what you should do if you choose to fly despite this request.

If you plan to fly in or out of departing event fields, you will be metered, most likely delayed via the Flow Control Managers depending on the workload at the event fields and enroute sectors.

If you plan to fly across the pond as non-event traffic (in either direction), your routing will be mandated based on avoiding traffic already booked to cross the pond, and you can expect to be assigned a very low level for the duration and potentially have no ATC for parts of your flight.

If you plan to fly intra-continent during the event, you will be subject to delays if your flight crosses the paths of CTP traffic and you will be delayed on the ground in order to manage the workload for our controllers. This can happen to anyone arriving or departing from an event airport.

Departing offline in order to circumvent departure restrictions on the ground is a violation of the VATSIM Code of Conduct and will be monitored by the supervisor team.

If you plan to cross the Atlantic in the Eastbound Direction:

You can expect a re-route on the ground (if covered by ATC) or in the air if already airborne when you fall under the control of ATC. This will most probably involve a level change compared to your plan, no higher than FL290.

If you plan to cross the Atlantic in ANY Direction, we recommend that you fly along one of the following tracks (ending in W being Westbound, ending in E being Eastbound):-

NE1W ISVIG ISVIG 6510N H6620 H6630 H6740 H6850 BOPUT BOPUT
NE1E BOPUT BOPUT H6850 H6740 H6630 H6620 6510N ISVIG ISVIG
NE2W IBROD IBROD AGORI H5715 H5720 H5730 H5740 H5750 DORYY DORYY
NE2E DORYY DORYY H5750 H5740 H5730 H5720 H5715 AGORI IBROD IBROD
NE3W TAKAS TAKAS GUNSO BEDRA 4920N 4930N 4940N 4850N NICSO NICSO
NE3E NICSO NICSO 4850N 4940N 4930N 4920N BEDRA GUNSO TAKAS TAKAS
NE4W BANAL BANAL H4220 H4230 4240N 4150N 4060N SLATN SLATN
NE4E SLATN SLATN 4060N 4150N 4240N H4230 H4220 BANAL BANAL

Any other routing, including the real-world westbound tracks for the day, will be limited to a maximum FL of 280.

We hope this guidance assists with planning your flight and helps you to understand why you may be delayed during your flight.

I wish I had known beforehand that the current build of the Ini A350 suffers from CTD inducing bug when the Navigraph Database is used instead of the default one. Something to do with the MORA indication on the PFD.

Well I didn’t know, and therefore my CTP to SBGR was sadly cut short by a CTD upon reaching TOC with Algiers Control. I also had switched off the AutoSave Function, so there was no way of me to resume the flight where my sim had crashed.

Well at least taxi, departure and climb out was fun. I only wish I would have at least made into Oceanic Airspace. Would have been my first time… :unamused_face:
