Bizare, le doc LSA réfère au paragraphe 2.5.6 de l'annexe 10 de l'OACI (dixit l'organisme agréé qui a installé mon code binaire) qui parlerait elle de la marque d'identification; cad, pour l'exemple qui nous occupe, de 99ABC.Le transpondeur mode S indiquera l'indicatif (F-J...) et pas l'identification (99...) ! C'est prévu comme cela sur les documents LSA. Jean Bossy l'avait déjà précisé dans son message plus haut.
J'ais donc recherché ce texte et voici ce que je trouve:
http://www.eurocontrol.int/msa/public/faq/faq.html#qa42
J'en conclus donc qu'en cas de vol sous plan de vol, c'est : FJ***
et sans plan de vol, c'est l'identification 99ABC
de plus en plus drôle
Mais je vais encore chercher, il fait mauvais et j'ai mon après-midi devant moi
Et voilà j'ai trouvé:
1 CORRECT SETTING OF AIRCRAFT IDENTIFICATION
1.1 To comply with European airborne equipment requirements, Mode S transponder equipped aircraft must incorporate an Aircraft Identification Feature. Correct setting of aircraft identification is essential for the correlation of radar tracks with flight plan data in the ATM and Airport Operator ground systems. Initial operational trials using SSR Mode S have shown that many aircraft are transmitting incorrect aircraft identification, e.g. BC_1234 instead of ABC1234. Such erroneous settings of aircraft identification prohibit automatic flight plan correlation and, if perpetuated, will severely limit the effectiveness of Mode S to relieve the shortage of SSR codes.
1.2 In accordance with ICAO Doc 8168 [PANS-OPS] Vol. I, Part VIII, 1.3, flight crew of aircraft equipped with Mode S having an aircraft identification feature shall set the aircraft identification in the transponder. This setting shall correspond to the aircraft identification specified in item 7 of the ICAO flight plan, or, if no flight plan has been filed, the aircraft registration.
1.3 Aircraft Identification, not exceeding 7 characters is to be entered in item 7 of the flight plan and set in the aircraft as follows:
Either,
a) The ICAO three-letter designator for the aircraft operating agency followed by the flight identification (e.g. KLM511, BAW213, JTR25), when:
in radiotelephony the callsign used consists of the ICAO telephony designator for the operating agency followed by the flight identification (e.g. KLM 511, SPEEDBIRD 213, HERBIE 25).
Or,
b) The registration marking of the aircraft (e.g. EIAKO, 4XBCD, OOTEK), when:
1) in radiotelephony the callsign used consists of the registration marking alone (e.g. EIAKO), or preceded by the ICAO telephony designator for the operating agency (e.g. SVENAIR EIAKO),
2) the aircraft is not equipped with radio.
Note 1 No zeros, dashes or spaces are to be added when the Aircraft Identification consists of less than 7 characters.
Note 2 Appendix 2 to ICAO Doc 4444 [PANS-ATM], refers. ICAO designators and telephony designators for aircraft operating agencies are contained in ICAO Doc 8585.
Donc ce que nous a dit notre ami Jean Bossy est bien correct
Merci, comme celà je pourrai économiser ma salive et me concentrer sur le paysage ....
