"Arrive Arbey time....."
Now this ones quite a talking point amongst the ranks. If you are given an RTA, what are the time tolerances ?
The two most common answers are;
1. 60 seconds early, 0 seconds late
2. 30 seconds early, 30 seconds late
What are your thoughts, and more importantly what are your Jepp/ATC references to back up your answer.
Cheers
