The BGA believes that every qualified pilot has an obligation to understand and respect the rules and regulations concerning UK airspace. To do otherwise can have serious consequences for the safety of the pilot and other airspace users. It is critically important that all pilots do their utmost to understand the airspace they are flying in and ensure compliance. It is also important that regulation of airspace is risk based and proportionate taking into equal consideration the needs of all airspace users. The BGA is committed to supporting that approach, including working with others to reduce infringements.
What is airspace?
In simple terms, the sky over the UK comprises of airspace that is categorised as controlled or uncontrolled. Most gliding takes place in uncontrolled airspace. There are various categories of controlled airspace, many of which are not accessible by sailplanes. All airspace, including uncontrolled airspace, is subject to temporary restrictions and changes. Information about restrictions and changes is published in Notices to Airmen (NOTAMs). All pilots should check NOTAMs (see below) as part of their pre-flight planning.
Respecting others…and staying legal
All pilots are urged to consider others who are also operating perfectly legitimately in the same airspace. This includes military, other air sport and GA, commercial air transport and emergency services. By staying aware of other operations, pilots can plan to avoid hazards. Instrument procedures/approaches that extend into uncontrolled airspace need extra care. Glider pilots should try to avoid flying close to controlled airspace, instrument approaches and ATZs as marked on charts. If it is not possible to avoid, timely radio contact should be made with the appropriate air traffic control frequency clearly and calmly describing your position – air traffic controllers are there to help.
An ATZ assumes the airspace classification of the surrounding airspace (eg Class G) and as such in most cases is not classified as controlled airspace. Aircraft are not prevented from operating in or through an ATZ, but they must comply with rules of the air and make contact with Air-ground/FISO/ATC as appropriate.
Infringements of ATZ’s and controlled airspace are potentially dangerous, disruptive and unacceptable. The CAA records all infringements, interviews the pilots involved, will require the infringing pilot to take a test, and may take legal action. Learn more about avoiding infringements.
Airspace access or air traffic control problems? The CAA provides a FCS1521 form for reporting issues regarding UK airspace including refusal of access. The same form is useful to report when we, as responsible aviators, do contact ATC even where we are not strictly required to – and end up getting attempts to control us or keep us constrained in some way as if we were flying in controlled airspace. The FCS1521 form is available here .
Aeronautical Information Circulars. AICs contain useful information and glider pilots are urged to regularly browse the latest updates on the NATS AIS website.
Airprox. When a pilot feels that the proximity of another aircraft was in their view unsafe, they can submit an Airprox report. Airprox reports are investigated and given a risk category. You can learn more on the Airprox website, which includes their published Airprox investigation reports.
Charts. Glider pilots use the 1:500 000 chart that is designed for use in visual navigation. The charts are regularly updated. Out of date charts should be discarded. VFR chart information, including a list of stockists, is available on the NATS AIS website. Radio frequency cards are available on the NATS website and linked from this webpage.
Cross country flying. Airspace is a major consideration. Learn more from the Cross Country and Airspace Guidance publication.
French Alps. Many UK glider pilots visit the French Alps. The airspace arrangements can be surprisingly complex. As ever, it is vitally important that pilots respect the rules. The FFVV has a dedicated French Alps airspace webpage here.
Gliding needs airspace. People and organisations sometimes struggle to understand why soaring pilots need free airspace. This briefing document that describes the soaring pilots perspective is helpful.
Gliding awareness. Pilots who don’t fly gliders may need some help in understanding how and where gliders operate. View the BGA briefing document ‘Gliding awareness for non-glider pilots’
This briefing that was published in the RAF flight safety magazine in Spring 2016 may be helpful.
GPS. Global Position Satellite navigation is used extensively in aviation. Most cross-country glider pilots use GPS to assist with navigation and to help avoid airspace restrictions. A number of freeware and commercial software options are available that take much of the load that otherwise would distract from flying the glider and looking out.
Controlled airspace changes every now and again. The 1/2 million hard copy chart is updated annually. It’s very important that GPS data files are also updated. You can read more about airspace files here. Pilots should note that they should take great care when programming their GPS before flight, and must always maintain situational awareness in flight through using visual navigation techniques and a current chart. This final point is nothing to do with ‘old school’ – it’s simply an important aspect of airmanship, ie cross checking and being prepared for equipment failure or pilot ‘finger trouble’.
Files. Keeping moving map airspace files up to date is important. Read more here.
Infringements. Airspace infringements are unacceptable. Learn more about Avoiding Infringements.
Letters of Agreement (LoA’s). Where there is a need and the related risks can be managed appropriately, it is possible to establish letters of agreement between airspace controlling authorities and operators. Sometimes these are national arrangements. In other cases these are local arrangements. Some LoA’s are legally binding. Others are voluntary in nature. In all cases, pilots must understand and comply FULLY with the detail within the LoA. If in doubt, ask. Do not assume.
Some clubs have a local agreement with NATS on flexible use of airspace. The ongoing success of the agreement between London GC and NATS is reliant on pilots receiving a specific, face to face briefing by the London GC. Unless that LoA briefing has taken place and pilots are briefed on the operating protocols in place on the day, pilots may not use the LoA. The LoA is not published on this website. Contact the London GC for further details.
The challenges of maintaining mutual awareness between busy flying operations is in part being addressed around Cambridge airport using protocols described in a Cambridge LoA that all glider pilots who are likely to operate in the Cambridge area are requested to comply with.
The published LoAs are available in the Airspace Documents Library. If a pilot or club identifies any changes or errors with published LoA’s, please contact the Airspace Committee via the BGA office.
Military – Learn more about the military perspective on the airspace we share with. The RAF flight safety magazine, Air Clues, is available here.
Information about activity that can be expected at military airfields is available here.
Military flying unit contacts for use during notification of significant gliding activity are available here.
A USAF supplied Mid Air Collision Avoidance leaflet relevant to the UK is available here.
NOTAM. All pilots are expected to check Notices to Airmen (NOTAMs) before flight. Failure to do so can have serious safety repercussions. Infringements of temporary restricted airspace will result in CAA investigation and may result in prosecution. Accessing NOTAMs forms a part of all glider pilot training. Any pilot who is unsure about how to check NOTAMs is advised to discuss the matter with his or her CFI or with another experienced pilot.
Learn more on the BGA’s NOTAM webpage.
Radio. You can learn more about using radio here.
Restricted Areas (Temporary) are a regular feature within UK airspace. A common example of a RA(T) is when an air display needs protection from other activity. The RA(T) will be notified in advance through NOTAM and all pilots must comply with the requirements. Usually that means avoiding a specific volume of airspace for a particular period. RA(T)’s are also notified through Temporary Airspace Restrictions listed within specific Aeronautical Information Circulars (AIC) on the NATS AIS website.
Rules of the Air. For further information, please go to the Laws and Rules webpage for helpful links.
Task notification. The BGA provides a Task Notification tool through the BGA Ladder website. Having logged on, competition organisers can upload details of the days task which can then be viewed by anyone signposted to the notification tool from a NOTAM. Use this link to view the daily tasks.
Task setting. Airspace is a major consideration when task setting. Learn more here.
Transponders. Aircraft flying in certain categories of controlled airspace or in all airspace above FL100 are required to be equipped with a transponder. In 2012 the BGA negotiated a number of non-transponder areas above FL100. These are detailed as exceptions in the UK AIP under ENR 1.1 and 5.2. Although the original exemption has expired, an extension has been granted until 31st March under CAA ORS 4 1131. The situation continues under review with both BGA and CAA keen to ensure that the level of risk is understood and continues to be appropriately mitigated.
Freedom to fly – you can help!
The BGA Airspace Committee works with other airspace stakeholders with the aim of maintaining reasonably safe airspace, equitable access to airspace, and freedom of movement across the UK for gliding. The task is ongoing and growing as an increasing amount of airspace is being demanded for the exclusive use of commercial operations. Volunteer assistance is always welcome. Airline pilots have particularly valuable experience. If you can help, please contact the BGA Airspace Committee chairman via the BGA office.
