It’s NORMAL here ... they bring them down FAST to about 2000 above the glideslope at the outer marker,, then you power up to keep from going through it ,,, at MCO you generally take off and land southbound , 4 runways , 2 17/35’s and 2 18/36’s ,, all 10k’ plus...
I had a EMB120 blow an engine above my house a few years ago ,, you could hear on the ground that he accidentally went into beta while at speed.
I think they do it so that the aircraft taking off have vertical separation ,, they turn a lot of them north after takeoff and they’re limited on the paths they can use ,, DISNEY WORLD has it’s own permanent “NO FLY” zone just to the west...
I am a professional pilot. I fly in Florida. No, it is not normal.
The paths you refer to on take off are called Standard Instrument Departures. None of them have a climb gradient of five or six thousand feet per minute.
In Colorado, with mountainous airports like Aspen, minimum climb gradients are in the 465 foot per minute range.
