The four new gates at the east end of te LCY ramp are properly sized for A318/E190 aircraft manoeuvres, without needing nose-in parking. These will presumaby be the gates of first choice for these two types.
I hope there is not an attempt to use the new types at the main gates 2-8, where not only is the manoeuvring probably not possible without a tractor, but the restricted passenger holding arrangements, which for a full 146 already mean passengers queueing for extended periods on narrow and steep stairs down to them, would undoubtedly fail any Health & Safety assessment for new construction.
