Normally it takes an aircraft around a minute to travel 3NM on final approach into Heathrow. Yesterday as straw poll in the 25kt headwind (not the strongest of the morning) I noted it took an A320 1 minute 45 seconds to fly the final 3NM.
An average of 180 kts over the last 3 miles?!! Bit high, they are usually down to only 160 kts outside 3 miles and then slow down even further inside 3 miles. It would take significantly more than a minute to fly the last 3 miles. A 25 kt headwind component would not almost double that time.
