Questions & Answers about Посадка была мягкой, и мне стало спокойнее.
Here посадка means landing, most likely an airplane landing from the context.
This noun can mean different things in other contexts, for example:
- посадка на поезд — boarding a train
- посадка деревьев — planting trees
- посадка пассажиров — seating/boarding passengers
So this is a good example of a Russian noun whose exact meaning depends on context.
