Thumbs up A340

The A340 will climb from lift off to 1500' AAL at V2 to V2+10 then automatically command an acceleration to 250 Kts or min drag speed (if higher) {about 270 kts at max AUW}at 1500' AAL then climb at this to 10,000' when it will accel to climb speed (~300 Kts/.8) You can frig the system to climb at any speed you like for noise abatement and/or performance. At VAA we do the auto speed schedule to at least 4000' to make the min gradient then accel if there is "no speed restriction" The ac doesn't accel and climb very well-especially the -300. Occasionally we do the early part of the climb at 190 with flap 1 -rather than completing the acceleration then climbing- if required to make a ht constraint. All this is do-able at MTOW on 3 engines without selecting full power-although I might! I know that many people moan about Airbus climb performance-especially the -300, but the ac is optimised for the cruise when an over powered ac is less efficient.
