Hardly rumours and news.

Not a rumour, since it was published in a government document, and not really news, since said document was released amongst great pomp and ceremony a few months ago. Maybe those guys at the Times have nothing else to write about....

Angry

Any chance of bringing them in on 27 Left instead of 27 Right weekday mornings?

Sick to death of being woken up by some BA 747 with what sounds like reheat switched on over my house at 2500ft.

I love flying and I love aeroplanes but the noise from aircraft during early morning (ie 5am) approaches to EGLL is becoming unbearable

PS: I lived in Hounslow for two years right underneath the final approach to 27 Left and it was never as bad - guess I got used to the (brief) noise!

Officialy the runways rotate at 3 every day, and the alternation switches every week, but due to T4 being the wrong side of 27L I assume the early morning arrivals for T4 are brough onto the South Runway a lot more frequently?
Guess you will have to wait until T5 opens before you can stop that 744 from waking you up in the morning

We use both runways between 0600 local and usually 0645ish local, because the inbound flow rates for the rest of the day are based on zero inbound delay at 0700 local. Also, at that time usually all the stacks are full of aircraft going round and round, while there is maybe one departure every five to ten minutes......it would be a waste if we didn't use that spare capacity to land a/c!

I have been the 'faulty' initiator of a similar forum around Brussels airport & DHL. It is quite interesting to read these postings and to notice similarities w/ BRU.
It looks like unilateral decisions on airport ops are the fact of the matter at LHR.

2 x LGW's side by side, I can hardly wait!. Pilots and ATCers better start taking blood pressure pills now in preparation.

Hi -
can someone advise what a 57dB & 91dB levels correspond to?
I know noise is subjective but I am trying to get a feeling for these noise levels. Tx.

In simple terms a sound that is 57 dB would be in the normal noise floor of any decent sized city. In other words you would not hear it unless pretty close. At 97 dB, you could hear it for many thousands of feet away.

Every 10 dB you double the noise energy of an event so a 97 dB event is 16 times as loud as a 57 dB event. Its been awhile, I might not be saying that exactly right.
