quick replies to some statements :
Too many sectors : because too many aircraft wanting to use same airspace = only way today to increase airspace capacity is multiplying number of sectors. each needs a dedicated frequency here you go.
Use data link instead of R/T : equip first and with ATN , today only (far) less than 10% a/c are ATN D/L capable
Retrofit is very expensive. ACARS ( FANS-1A) is not suitable for ATC dense airspace operations ( too long responses times and no acknowledgment messages back )
Drop first 1 : excellent idea., but against ICAO / ITU regulations which stipulates that frequencies on R/T have to be read in full (to separate HF from VHF etc..) Attempts to change this failed. Nevertheless some Aeronautical charts have already done this.
Prepare a list of frequencies to be crossed en route :totally useless in most dense airspace as sectorisation is variable according to traffic load and staff availability. You never know in advance which sector is bandboxed or separated, and consequently which frequencies are in use.
121,5 : fully agree ; but as long as States or ANSPs will not monitor it , identify the culprits and fine the perpetrators nothing will change.
Golden rules of today dense European airspace : :1) make a position report at least every 30 minutes if you have not been called. I) if you hear nothing, you are probably on the wrong frequency.
