![]() In my experience it used to great effect as an abbreviation from a pilot to a controller to sum up the following longer message: ![]() It is very ‘Biggles’ for those who don’t have experience using it, but it is also quite funny for those who do, because it can be used like all good abbreviations to carry a longer hidden meaning. On many levels “Roger” is quite an amusing RT word. It was an unexpected piece of information at the end of a tiring flight and I wanted time to think for a second about how I needed to react, if at all, whilst simultaneously letting the controller know that I had received that transmission. I can remember using “Roger” at the end of my transatlantic flight when an air traffic controller in Oxford warned me that a Spitfire was manoeuvring in my vicinity. But there are many other situations where information is passed or a suggestion is made, but it is not an instruction as such. There are many situations where a pilot is given an instruction, which they are expected to comply with, in which case the controller will expect to hear “Wilco” (Will Comply) as part of the response by the pilot. If an air traffic controller passes a piece of information to a pilot, which the pilot hears clearly but is not yet sure what to make of it or how it will influence their decisions, then “Roger” is the only appropriate response. That sounds a small and pedantic difference, but it is a hugely important one. ”Roger” is used, particularly commonly in aviation, to mean that the transmission has been received, without giving any indication as to whether it has been understood or whether an instruction will be complied with. On this subject, the word “Roger” is also misused frequently, but it too has a very definite and much misunderstood meaning: it means “I have received your last transmission.” In military and maritime environments they are still used. The two should never be used as part of the same transmission.Īviation has largely dispensed with both “Over” and “Out” depending on an almost ritualised structure of words combined with tone and rhythm to achieve the same effect. ![]() “Over” can be used many times during the course of a conversation, but “Out” should be heard only once and as the final word. There is not an instance when the two should be used together. “Out” means that the transmitter has finished speaking and is not expecting to hear any more from the receiver. “Over”, used at the end of a transmission, tells the receiver that the transmitter has finished that section of their broadcast and is expecting and will await a response. The two words have distinct and contradictory meanings. It is never used for a good reason: it makes no sense. This expression is never used these days by those with any training in radiotelephony or ‘RT’ as it is more commonly known. The expression, ‘Over and Out’, brings a smile to anyone with experience using radios.
