What I mean are the LPV approaches with minima down to 250 ft AGL, requiring a SBAS receiver. I agree that EGJA (Alderney) has such approaches.
(APV baro)=Vertical Guidance by means of baro VNAV. Taking e.g EDMA, RNAV (GPS) RWY 07, our avionics equipment is such that we are eligible for the LNAV/VNAV minimum of 1930 ft WITHOUT a SBAS receiver. The term "EGNOS" is not mentioned on the approach plate.
(LPV)=Localiser performance with vertical guidance. On the RNAV (GNSS) RWY 10 approach in LSZR, however, itīs a different story. Here you have the LPV minimum and also find "EGNOS" on the approach plate. You MUST have the SBAS receiver in order to be eligible for the LPV minimum.
I read an article somewhere that the introduction of new EGNOS approaches
is slowed down by bureaucrats for whatever reasons.
