At Midday MAN goes into 'single runway operation' for upto 4 hours, queues inevitably build up for departing aircraft. Usually once an outbound aircraft has taken off the next incoming is cleared to land. Today however was different, operating margins were much tighter, and incoming aircraft were given the instruction to "land behind the departing aircraft", even though the departing aircraft was still rolling at the time. Is this a new procedure or new instruction? Is it common elsewhere?
It lead to 2 incidents today, both around 1pm. A departing BA citiexpress regional flight pulled onto runway 06L to take off and developed a fault, an incoming BA LHR shuttle had to abort landing on short final, this may not be too unusual but at the time the incoming flight was less than 30 seconds from touchdown. It went round again and landed some 15 minutes later.
The second incident involved BMI's Washington flight. Whilst it was rolling a BMI Embraer was 'cleared to land behind it'. Although the Washington bound 757 left the ground around 10 seconds before the Embraer touched down, the Embraer captain was far from happy. He reported ground turbulence on the runway and suggested that he was given clearance to land too close behind a departing aircraft.
I often here on my radio that 2 departing aircraft have to be separated by 1 minute, or 2 minutes. Is there a standard timing procedure between departing and arriving aircraft using the same runway?
