Proposed Radio Mandatory Zone (RMZ) Framework Briefing 7 th January - - PDF document

Framework Briefing Notes

7th January 2015 CAA House Kingsway In attendance; (EGNR ATC) (CAA) made a presentation regarding the propose RMZ. advised us of the ‘red tape challenge’, clarifying that an RMZ may be a suitable solution to Hawarden’s issues as it is less restrictive to airspace users. However, it was noted that RMZs had only previously been used for Radar limitations during the Wimax upgrade programmes

• r as a stop gap, prior to implantation of class D airspace.

clarified that the adoption of an RMZ would not lead to any changes in the routings of VFR and IFR aircraft from those available and used at present. advised that whilst the concept of a RMZ did not necessarily fall wholly within the remit of the CAP 744 Airspace Change Process, the document should be used as guidance material. The scope of consultation and the associated reports should be proportionate to the impact. confirmed the stages and associated timeframes of the Airspace Change Process that would need to be followed. He also clarified the CAA decision process and promulgation of changes should they be approved. clarified the pre-consultation stakeholder engagement that had taken place and outlined the existence and content of the web site. discussed the airspace operators that would be directly affected and also clarified the typical scope of consultees in respect of airspace users. It was agreed that due to there being no changes in disposition of aircraft routes, consultation with parish councils and planning authorities would not be mandated. confirmed that Airbus communications would guide the scope of the consultation in respect of parish councils and planning authorities. re-capped on the CAP744 process and next steps. The meeting was concluded.

Why are we applying for an Airspace Change?

SAFETY & EFFICIENCY

• Hawarden Airport is situated within Class G Airspace where two

way communication with Air Traffic Control is not mandatory providing aircraft remain outside of the Aerodrome Traffic Zone (ATZ).

• The whole track of an IFR approach to Runway 04 and a

significant part of an IFR approach to Runway 22, aircraft

• perate within Class G Airspace.
• For both runways, aircraft departures are flown in Class G

Airspace before entering Class A (Controlled Airspace).

Why are we applying for an Airspace Change?

• Large and fast aircraft mixed with GA traffic.
• Forecast national air traffic increases & known A3ST increased

activity.

• Poor radar returns from small aircraft.
• Variety of ATS agencies in area (Hawarden, Liverpool,

Shawbury, London FIS). If we know a/c intentions in advance, we will be able to vector our traffic to ensure the safety of all, whilst minimising the disruption to all flights.

Why are we applying for an Airspace Change?

Airspace Infringements Complex controlled airspace in the vicinity of Hawarden has a history of airspace infringements. Hawarden can provide navigational assistance to help avoid these infringements.

Airspace infringements account for 20% of reportable incidents at Hawarden. Of the 22 reported Airspace infringements, 4 were Hawarden ATZ infringements, 8 were N864 infringements, 9 accounted for infringements of the Manchester TMA/CTA (one of these also infringed N864) and 2 were Liverpool CTA

• infringements. Of the 22 reported Airspace infringements, only 4 were being

provided with a service from Hawarden ATC. (Review of Hawarden incidents 2013)

Possible solutions

CTR Class D Airspace Too restrictive to operators. More than is needed. TMZ This would provide most of the information we need but not all & would be an unreasonable demand on local airspace users. RMZ This would provide all of the information Hawarden needs & would aid aircrew awareness, providing reasonable alternative means of compliance can be incorporated.

Why an RMZ?

• An RMZ is a piece of airspace of defined

dimensions wherein the carriage and operation of radio equipment is mandatory.

• All flights operating in the airspace designated as

an RMZ, shall establish two way communication before entering the RMZ and maintain continuous voice communications with ATC unless in compliance with an alternative procedure.

What must a pilot do?

Before entering the RMZ, an initial call containing:

• call sign & type of aircraft.
• position, level, the intentions of the flight.
• Maintain a listening watch.

What are we proposing?

• RMZ Designs – design not finalised.
• Revised Letter of Agreement with Liverpool Air Traffic Control (subject to

impact).

• Revised Letter of Agreement with Llantisilio Gliding Site.
• Letters with others within the RMZ.
• Alternative means of compliance (excerpt from SN2014/007 – Southend RMZ

…. In essence, before entry to the RMZ, all aircraft are to establish two-way communication with Southend ATC, although aircraft not fitted with radios can still

• perate in the RMZ provided the pilot is able to co-ordinate arrangements with

Southend ATC (+44 1702 538420) prior to departure)

• Possible use of SSR ‘listening squawk’.

Effects on operators

• Comply with communication obligations
• Increased awareness provided to aircraft by common frequency.
• Aircraft may be asked if they can accept modified routing or level,

if not agreeable, Hawarden will work around.

• Non-radio aircraft can be given an exemption provided the flight

details above are passed by phone.

• RTF failures (inbound) may continue to land at Hawarden.
• RTF failures (transit) having passed details may continue.

What have we done so far?

• Assessed options for Airspace classifications.
• Discussions with Local ATSUs & some local airspace

users at open evening.

• Letter to local flyers, and organizations.
• Website www.hawardenrmz.co.uk.
• Feedback from website.
• RMZ design being prepared for consultation.
