Just for interest, I computed on Ipad the landing performance: The A320 CEO and A320 with sharklets have exactly the same VAPP for conf 3 and conf Full. With a landing weight of 60T it was VAPP of 135kt in F3 and 138 for conf Full.
the 320 NEO was Vapp 140kt conf 3 and 130kt conf full.
Weird that in conf Full the speed is actually 5kt lower but in Conf 3 it’s 2kt faster. Any explanation for that? the flaps and slats extension are exactly the same. IAE and PW engines.
I also compared the A321 CEO versus the NEO and for a landing weight of 70T VAPP conf 3 was 146 kt & 141kt conf Full versus 146kt conf 3 and 135kt conf full on A321 Neo. 11kt difference! But this is explained by the difference in flaps extension difference in Config Full the Neo has flaps down to 34 degrees versus only degrees for the 321 CEO.
