Minimum Ground Time Day

When aircraft are running late, the airlines expect us to achieve the almost unachievable, doing a complete turnaround on an aircraft in the minimum time. That’s an offload of passengers, bags, cargo, catering, reload of all, fuel, complete clean of the cabin, change of crew, boarded again and off blocks.

Different airlines have different minimum ground times for each of their aircraft. For example, one airline says an A320 with 180 seats should be on blocks for only 50 minutes. A normal turnaround for it would be 60 minutes and yes those 10 minutes really do make a difference.

Such a target can be achieved but only with the complete co-operation of all parties involved, not least of which is the outbound crew turning up in time so they can perform the security checks and we can commence boarding. Then again it’s no use them being onboard if the cleaners haven’t finished yet since security checks can’t be done. And so on and so on back down the chain.

Today is already a bad day. As I arrive early in the office to prep myself for my shift, all my flights are going to be late inbound and now the pressure on me increases ten fold to try and claw back as much time as possible and at the least, achieve that black magic of a minimumn ground time turnaround. Showtime, the curtain's already up.

1604: My aircraft comes to a stop and the ramp guys spring into action, putting the chocks in place. As soon as the aircraft beacon light stops flashing, the steps move into place front and aft, the baggage trucks take their position and the fueller pulls up under the aircraft’s right wing. With the doors open, 180 passengers and 3 babies pile out through the exits with the usual expletives over the weather. The aircraft is already 14 minutes late arriving and was scheduled for its next flight at 1650. However due to the late inbound we are now expected to claw back some time and have it away again in 50mins, 1654. No time for stress ball, it’s chewing gum or nothing!

From when the wheels stop moving until they start again my head is a tangled mess of endless objectives I need to carry out to get this aircraft away again a.s.a.p.

1616: As the last passengers descend the front steps the cleaning crew are already making their way onboard via the aft. Two catering trucks have arrived, one to de-cater and the other to re-cater with ‘fresh’ meals for the next flight. After a quick reminder to the relevant person, the toilet servicing trucks pull into place and start emptying the aircraft waste tank and refilling the fresh water tank.My mind rushes to the next task, loading!

The outbound cabin crew turn up and begin their checks onboard the aircraft. No time for idle chit chat this afternoon, inform them of the passenger load and any special assistance passengers and leave them to it.With an almost full load of passengers for the flight, every minute we have for boarding is precious and the sooner they are ready, the better.

15 minutes before departure and the first passengers are let onboard the aircraft as the crew finish up their prep. As I peer up to the gate area through the glass I see a long line of people all waiting to pass through down to the aircraft. I pray all the passengers are there, today is no time to be turning up late and having me hunt for their bags. Half way through boarding the last of the outbound bags are loaded and the hold doors closed. I pray they shalln't need to be opened to remove bags if passengers fail to turn up!

1654. The new estimated time of departure. Did we make it? Almost, all the passengers are on, the doors are closed and the aircraft ready for pushback and start up, but it’s the middle of the afternoon rush and we’ll have to wait our turn in the queue. Que sera sera, but we achieved our 50 minute turnaround and the rest of the delay is effectively beyond our control. Still, it’s only a 4 minute delay and the 4 hour flight is generously overscheduled so should arrive on time at the destination.

1711: I catch a glimpse of my first flight rotating off the runway and climbing skyward. Having seen thousands of take-offs it still amazes me and I still feel privileged to work so closely with it. However it’s no time for dwindling in thought, I’m already at my next aircraft and trying to achieve another nigh on impossible time of 35mins on a 148 seat aircraft. What is it with late flights today? The stress continues for now.

I'm stressed just reading this! And you didn't even mention working in freezing weather, rain storms and between lightning bolts!

I look forward to more peeks at life from your side of the operation. Well told.

As well as entertaining, you're going to educate passengers and pilots both with your new blog. I an tell there are a lot of stories out there.

Ha Ha, this is so true. I work with the express jets so our turn time is 24 minutes from block in to block out. God forbid there be a rain cloud near ORD when the GDP comes out to play.

You mentioned that different airlines apply different turn times for the same aircraft... Does each airline come up with it's own sequence/process for the turn? Or do they just try to minimize the time using the same process?

Thanks for the comments.

head in the clouds,
Different airlines have their own way of doing things. For example one airline might have the crew assist the cleaners or clean the cabin in place of cleaners thus reducing the time, or do a crew handover, ie not leaving the aircraft until the outbound crew have turned up to make things easier.

It's an interesting question and one that confuses me, two airlines, same aircraft, same market, different requirements. I'll do a post soon on the differences some airlines have to increase the time aircraft can spend in the air.

As a passanger who has spent several hours looking through the windows in the terminal, seeing airplanes come and go, I wondered how this got done. So I am looking forward to reading more of your busy and crazy days...

Have to fly this weekend from PHL. Sometime ago I decided to never fly form PHL to another connecting flight. Happily, this time is a direct flight.

Wow, this brings a new perspective to the airline biz. Can't wait to read more about your thoughts.

Your blog is very informative, enjoyed reading and felt I was also in the ramp.
Quick question: Is ground time and turn around time the same?
