Its NOT required, DONT say it!!!
That makes a long story short. It's all about adhering to the rules guys! I don't have to say this, do I?
He told me that "Roger " means, I understand & will comply. "Wilco" means I will comply
Seriously?!! A check captain said this??
Roger: I have
received your message..ONLY received it!
Wilco: I have
understood your message and
will comply with it!
Now your Checker is the one who should be grounded for R/T!
