Is the sentence clear?

[NewHope]

Basing on actual experience or perceptual knowledge would help you a lot, while without the experience or knowledge you might feel not so easy to understand my introduction.

[Francois]

Prior knowledge of the topics discussed in this introduction is recommended.

Hi Francois,

I didn't get you well.

In a conversation:

A: I'd be very pleased to listen to you if you introduce some techniques of driving a big airplane.

B: (Your listening) Based on actual experience or perceptual knowledge would help you a lot (in understanding my introduction), while without the experience or knowledge, you might feel not so easy to understand my introduction.

That is, the subject has been missed out.

[Francois]

OK, I thought it was for some kind of essay.
I'm afraid it will be difficult for me to make a clear introduction if you have no practical knowledge.

Hi Francois, what did "practical knowledge' refer to?
