9 - Procedures for Use of ‘HusBos Radio’ 127.580



The Gliding Centre has been issued its own dedicated radio frequency by The Civil Aviation Authority. This is so that during busy periods we can avoid any safety issues with cross talk from other gliding sites. The allocated Husbands Bosworth frequency is 127.580 and is for the Passing of Safety Information Only. It is not to be used as a local or X-Country general chat frequency. 



This frequency has the restriction that it may only used within 10nm of HusBos & not above 3000ft agl.



Deenethorpe airfield - 4nm NE Corby - also uses this frequency!


Call Signs

Excluding aircraft call signs there are 2 additional call signs that may be used on this frequency. They are:


“HusBos Radio” which is used by the operator of the radio within the launchpoint and any pilot wishing to contact that radio.


“HusBos Traffic” which is used in all blind radio calls ie. General calls not to any specific person, the majority of calls at Hus Bos.


Examples of Its Use

Please note that our normal aerotowing launch signal calls will remain totally unchanged. Apart from the aerotow launching signals: “TAKE UP SLACK”, “ALL OUT” and STOP”, only flight safety calls are to be made from the ground.

We have set out some examples of how radio calls may happen, demonstrating the use of the different call signs. In the examples given we have broken each radio call into its constituent parts with the use of ‘–‘ to help with the understanding of each call.

Blind Radio Calls

The purpose is so that pilots, if they so choose, can make a general radio call to all those listening, announcing their intentions and thus enhancing everybody’s situational awareness and safety. There is no need to reply to these calls unless it is relevant to do so!

An example might go:- 

‘HusBos Traffic – Glider FXQ – Final Glide 5kms from the South East’

‘Glider FXQ – G-SS downwind 27 Left’

Tug SS is now aware of a possible conflict with Glider FXQ and will be keeping a sharp lookout for him. Glider FXQ is also now aware of the possible conflict and will also be keeping a good lookout as well as maybe adjusting his circuit joining procedure.

Blind radio calls can also be used on the ground, again this is so that other pilots and ground operations are aware of any intended actions:


‘HusBos traffic – G-TX crossing 27 to the hangars’

‘G-TX – Hus Bos Radio – caution cables’


‘HusBos Traffic – G-OS backtracking 27’

      ‘G-OS – Hus Bos Radio – winch launch in progress’

‘HusBos Radio – G-OS – Roger’


In the last two examples, if there is no flight safety issue, there is no need to say anything.

As a general rule, If in doubt - say NOWT.



Direct Calls To HusBos Radio

All pilots – please DO NOT make any requests of ‘HusBos Radio’ OTHER THAN requesting which runway is in use (flight safety information), as a general information service is not allowed on this Air/Ground frequency. Use it ONLY to listen out to what others are doing and to inform others of your position and intentions.


Ground operators should be very clear on the fact that they CANNOT pass any message that could be construed to be an air traffic control instruction OR anything that could be construed as an approval of any proposed action.




Examples of radio calls might be:

‘HusBos Radio - Helimed XX is transiting through your overhead, any traffic information?  Over.’

‘Helimed XX  - Hus Bos Radio  - there is winch launching in progress’


‘HusBos Radio - G-ABCD inbound to you from XX request joining information over’.

             ‘G-CD – Hus Bos Radio – runway 27 in use – winch launching in progress’


Ground Operators Please Note The Following!

Radio operators must ensure that our FULL CALLSIGN – that is, including the suffix “RADIO” is used in response to the initial call.   e.g.  ‘Helimed XX - Hus Bos Radio…..’ 


DO NOT reply to any call unless it is directed at you (HusBos Radio) OR that Flight Safety Information is required AND that you are very clear about any reply!


Police 22

The police helicopter operates from the field to the south of us.  They will call when lifting and when returning to base.

If you hear them call, ie:- ‘Police 22 lifting’, or ‘Police 22 returning from the north’, please acknowledge them with ‘Police 22, gliding in progress’.  Quite often helicopter pilots not familiar with our operation will make a call and if they receive no answer will assume that we are not operating and cross our field in a manner that could cause us a problem,
