Nickmanl....
The proposal that appeared in the news was just that. And BA thought it up for purely commercial reasons.....another 100ft or so altitude over London would not make any difference to noise or emissions.
However, it would mean that BA's a/c can land halfway down 27L/R and vacate just where T5 is being built! Much shorter taxi! Funny that.
I bet BA wouldn't want to pay for the extra ILS needed, or the installation of new runway lighting that's needed!
Any reverse thrust greater than reverse idle is not allowed at LHR, except in wet, icing or limiting conditions
Not heard about this........only the request that reverse isn't used at night if operationally applicable.
