Hi, I have an assignment in which I need to find the time and distance it takes for an A320 to brake from 30 knots to a full stop.
To do so I need to know the braking deceleration during taxi.
I have only been able to find the deceleration values for autobrake i.e.
LO - 2m/s2
MED - 3m/s2
MAX - 6m/s2
Am I right to say that autobrakes are off during taxi? What are the deceleration values of manual braking during taxi?
Thanks in advance.
In any academic assessment, exam or assignment, it is important to ask yourself
"What am I being asked to demonstrate that I have learnt here?"
Is this a basic physics unit which teaches you to calculate time and distance to decelerate to a standstill from a known velocity given a known acceleration?
Or is it a unit which teaches you to track down typical performance parameters such as the likely deceleration of an A320 at taxiing speeds?
Or is it perhaps intended simply to get you to calculate an estimate (with no fixed "correct answer") to make sure that you thoroughly grasp and remember how much space is required to stop?
Once you've answered this, you can then set about providing the type of answer required.
