If you want to know something about performance, read AC 91-79a. That will get you the most basic information you need. Then you need to read Part 25 requirements and AC25-7D Chapter 4 (although the whole thing is good to know), AC 25-32, SAFO 16009 and EASA certification/peroformance requirements. A lot of what Embraer does is to comply with EASA rules. You especially want to spend time on EASA's contaminated runway takeoff and landing information. All of that will give you the background information in AC 91-79a that will help you to understand why AC 91-79a teaches what it teaches.
If you do all that, you'll start to understand why we do what we do and why AOM1/FM1 says what it says. AOM1/FM1 only tells you how to comply with all the above. But if you don't know what you are complying with, you won't have the urgency to do what is necessary. That is when we start to see floating and carrying extra speed along with minimal brake usage. Also, if you know the information in the documents above, you might start catching all the mistakes our dispatchers make. I've filed at least 4 ASAPs for improper performance calculations over the last year. Just looking at the TPS is not enough. Dispatchers are like FO's, they are there to kill you.
Did you ever wonder why you rarely see a mainline pilot float to get a "greaser"? I get it is part of the development of a young pilot to think a good landing is a soft landing. And maybe I'm short cutting pilots that work here by trying to teach them this stuff instead of letting them figure it out for themselves. But every landing, every time needs to be on the 1000 foot marker at Vref-x. You can solve for x if you read AC25-7D.
Passengers and Flight Attendants do not define a good landing. Stop listening to their opinions. They are not the experts.
Ok, maybe it was a lot preachy. I'm sorry about that, but not about the information.
“I get it is part of the development of a young pilot to think a good landing is a soft landing.”
Classic. Stupid FOs never learning that a firm landing in the touchdown zone is better than a greaser that is floated down the runway...
If we were flying together and you decided to “teach” me that as if I wasn’t already aware, I would lose all respect at that point. Glad you feel like you have some sort of secret knowledge though.
Too bad the majority of the intentional floaters in the left seat are the lifers who have the most experience. They know they aren’t going to the big jets and could care less about the laundry list of references you just gave because landing distance is almost never critical in a 140/145. I’ve seen more “power-on” landings from old heads than I can count.
