I was controlling at London City on advanced for about 3 hours today and it was astonishing the amount of people who just decided it’d be a good time to back taxi right now.
You need to be cleared before back taxi
Just because you are cleared to taxi to a runway does not mean you can back taxi down a runway to the runway you were cleared to taxi to. To cross a runway you need permission. Samething with back taxi.
Do not request runway crossing
If you need to back taxi the tower will tell you to back taxi. The tower will not clear you if you do not have enough room to take off, so you do not need to worry. When you are first in line request take off as you normally would and tower will tell you to back taxi when ready
Airports such as London City that have back taxi get congested much easier because of the extra step. So please be patient. It is quite possible when busy you could be waiting upwards of 10 minutes. Today I had a couple people wait 20 minutes to take off. Landings have priority over take off so you need to be patient.
Do not request take off more than once. Just because you are waiting awhile doesn’t mean we forgot about you. You can use your radar and see there is a lot of inbound traffic, so there is no use requesting again, I promise we didn’t forget about you.
“Back taxi line up and wait” just means to back taxi and line up and wait on the runway. I saw many people backtaxi and hold short when I told them to line up and wait.
Just because the person in front of you back taxis doesn’t mean you can. I saw a conga line tonight. Someone back taxied and everyone else followed, no one being cleared.
Do not enter runway unless instructed to
Runway crossing is not the same as back taxi
