Manchester ATSOCAS for IFR Flights

I fly a commercial jet from an airport which is located such that it requires a transit through uncontrolled airspace to get to the airway. We are normally handed straight to MAN on departure, who normally give us a heading and Traffic Service.

Why not a Deconfliction Service as standard?

I get it when I ask, so it's not a problem, just wondering why it isn't offered first off to what is obviously an IFR high perf aircraft unlikely to want to manage its own separation.

Can any ATCOs shed light?

Why not just make the request for DS on initial contact with Manchester - it is up to you to request whatever service you require. Better still, why not make the request to Hawarden/Blackpool (or wherever) Tower before departure?

EGBK,
Which frequency do you normally call MAN on?
I might be able to hear you on my radio.

Food for thought 2 Sheds. I will try asking up front for DS next time and see what happens.

My query was really why ATC offer a TS as a first option and not a DS - particularly when they are providing Radar Control to most other traffic on frequency and will to us within a couple of mins too.

ATC on initial contact are meant to ask " What type of service do you require"..........therfore ask for what you want....it may not be available due traffic loading but if you dont ask you dont get!!!!!!!!!!!!!!!

Fisbang - I guess they are but things are busy at that stage for both parties and we are a bit of an anomaly (as I said, everyone else is in CA), so they just state what they're offering. What I'd really like to know is if MAN have an SOP covering what they offer as standard in such circumstances.

I take it you are being transferred to a Manch ACC sector after departure?

If they are busy with radar control and other traffic at the time of transfer, offering you a DS immediately would increase their workload more than a TS would. Due to the traffic they are already working they may feel that they cannot safely provide you with a DS even though as you put it, "you will recieve a DS in a couple of minutes time".
Obviously Class G airspace is available to all users without speaking to ATC so as soon as you enter controlled airspace you will get a radar control service because they know who is there (apart from any infringers!!) and can provide seperation accordingly.

DS being the standard service outside controlled airspace is incorrect. ATC will try to provide you with the most appropriate service they can this might be a DS,TS or even a basic service depending on several factors (mainly traffic levels).

No SOPS as such for ATSOCA. Hope this helps.

EGBKflyer - prior to 12th march, SOP equivalent was a RIS at most for joiners, I think now that may have been superceded by the CAA saying we should offer the maximum available service, and it is quite a big difference between TS and DS. The process may improve in time for those who are you in your situation.

EGBK,
Have you actually been to MAN to ask them?
Allegedly, you have about 9 months left to do so.

Because RCS has the benefit of controlled airspace! And with the main function being to provide that service in CAS, one is not going to fall over oneself to take on a workload and responsibility for which there might not be the capacity.

Landedout - that is what I suspected (I used to have the same dialogue for RIS/RAS). CAP 774 s(Appendix B) suggests DS as a 'standard' for traffic on Advisory Routes and although we're not on one of those here, I feel the same should apply to our case. Forgive my ignorance - is DS much more work than TS in an environment where most of the traffic on freq is under radar control?

Zooker - work commitments have so far prevented me from visiting MAN this year, that's why I tried Prune first. I will be making contact with them though. Maybe I'll find out then if they're really picking and choosing 2 Sheds!

Advisory routes are Class F airspace normally. It sounds like your short transit is Class G which is a completely different ball game for the ATCO. Advisory airspace is for participating IFR aircraft. Class G as mentioned is for IFR or VFR whether talking/recieving a service from ATC or not.

The new ATSOCAS state that it is the pilot's responsibility to request the type of service required. If this isn't stated in the first call then you can probably expect the controller is offering the level of service he/she is prepared to give, taking into account their current and expected workload.

There is no SOP, controllers are expected to provide the full range of services as appropriate so will upgrade where possible on request - however traffic inside controlled airspace always has priority over that outside. If the controller feels they cannot take on the responsibilities of a DS then they will offer a TS or BS - and yes, there's a big difference in the workload! DS cannot be provided below 5000ft, so if you are calling MAN on departure this could be why you are initially offered a TS.

Your comment about IFR not wanting to manage its own separation sounds a bit worrying to me though - regardless of the type of service agreed on, outside controlled airspace collision avoidance remains the responsibility of the pilot, and you cannot assume that a DS will be available. Outside CAS we have no idea of who/what is operating and what it is doing, and whilst we will try and give traffic info/avoiding action its not always easy when unknown aircraft pop up suddenly or change direction. I would hope that the pilot is keeping a good look out - after all, radar has a time delay!

There is no 'standard' offer of service level. Its just what fits at the time. DS has quite a level of responsibility for the controller in an unknown envronment. Why offer it if the pilot only wanted a BS in the first place?

just came to my attention in this thread but class f routes are advisory routes shouldn't they be called deconfliction routes now? ( albeit i have no knowledge of what happens in class F outside the uk)

No. App B of CAP774 explains all.

Have you ever visited an ATC unit - any ATC unit that has a LARS function?

I think if you did you would soon find out why controllers do not give away DS for free.

The fact you fly
what is obviously an IFR high perf aircraft
is one good reason not to give a DS willy nilly - it is (genreally) more difficult to provide standard seperation for high performance aircraft (if they are being flown in a robust way), than it is to provide seperation for something plodding along.

Just because your aircraft is
...obvioulsy an IFR...
means nothing OUTCAS - it does not mean you are obviously IMC.

As for not wanting to provide your own seperation i.e. 'see and be seen' why not? Military single seat jet pilots can manage it - and they are high perfomance with a much bigger cockpit workload.

ATSOCAS is a contract, still is, always has been.

It is the responsibility of the pilot to state what service they require, the controller, if able - bearing in mind workload versus legal responsibilities for each type of service - will provide that service. If unable they will provide a lower one.

As an aside, in the LTMA it is standard practice not to give DS to aircraft OUTCAS that want tojoin. In fact the nly time we would give a DS is if we cocked up and took an aircraft OUTCAS by mistake. Even if an aircraft elects to leave CAS due weather etc, we do not have to give it DS. It is all to do witrh duty of care and ability, or otherwise to provide what is contracturally required for the service.

I'm not having a go at you in any of the above though it might sound like it, it is just that in your posts you have made what seems to be a few assumptions. I want to debunk those because it could be dangerous for anyone to misunderstand the thinking behnd the provision of ATSOCAS.

Seriously, try to get a visit to a radar unit - it will be of benefit to both you and the controllers because there are always things both parties can learn from each other.

Anotherthing - thanks for your comprehensive reply.

I have visited several radar units in my time, though not recently. It's on my list for this year as time permits... I would be genuinely interested to see how workload changes with a DS service offered and as a current FISO, I can appreciate how workload can change quickly!

I am well aware of our responsibilities re managing our own separation, however trying to keep a lookout in a commercial jet is not easy - certainly we have less all-round vis than a bubble-canopied fastjet and each pilot has blindspots due to the cockpit width etc. ACAS helps but obviously won't see everything either.

Clearly ATSOCAS is a contract, as it always has been. The original query was from my point of view that a DS manages risk better than TS in the environment I find myself in and wanting to find out all of the reasons why that view is not necessarily shared by others. I think you've answered that and de-bunked the assumptions I was deliberately making.

Blueberry thanks too for your input.

I'm involved with company flight safety and will be raising this subject at our base. Your answers will help to clarify the situation for all. Worth noting too that the Captain I flew with today said RAS (i.e. DS now) was a minimum level of service required by the SOPs in his old company - a major UK turboprop operator.

I take your point about the visibility!!

In an ideal world a DS would be provided to aircraft that are obviously IFR (not necessarily IMC) - unfortunately with the proliferation of commercial airports or operations that have not got the luxury of CAS, this problem has increased greatly in the past few years. Obviously from your point of view, a DS is preferable, but from an ATCOs, it might not be!! (Though if you ask for one, they should provide you with it unless they have good reason not to).

It's particularly relevant in the vicinity of the York with lots of Mil activity around as well.

Although it would be nice to be able to give every commercial operation the benefit of CAS, the GA community would be up in arms, as would the Mil.

The best way to answer your question is for you to say which airport it is and what is the MSA? A Deconfliction service cannot be provided below this so for instance, if you were getting airbourne from Hawarden, the MSA is 3100ft and the base of controlled airspace is 3000ft... Therefore you will never get a DS as by the time you climb above the MSA, you are inside controlled airspace and will be on a RCS.
