Hi everyone! I recently took a trip on Southwest from Phoenix to San Jose. An interesting thing happened on the take-off out of San Jose. There was the normal power reduction at about 1000 feet, but then another unexpected and pretty large reduction about a minute later. The engines powered up again after about 2 minutes and things went on as usual. I never felt uneasy or in danger in any way, but I'm a little confused about that second power reduction. Things were nice and smooth, no clouds... Does anybody know what happened? Maybe noise abatement procedures?
