# Connection Time Calculation

There is a ground (tournaround) time for aircraft, and then there is a minimum connection time for passanger.

My AC has a segment blocked time e.g. 0100 pm - 0400 pm from C to A. This already includes ground time at A, because the AC is ready to fly another segment at exactly 0400pm (or 0401pm). Let's say the minimum connection time is 1 hour. How do I know which of the ground time can already count as a connection time? (suppose the Ac arrives at 3.20, so 3.20pm through 0400pm would be 40 minutes, so the passanger would need extra 20 minutes to connect to another flight).

Imagine that i want to fly: C-> A -> B. I need to know how much is the ground time at A, in order for me to schedule proper departure from A to B, so a passanger that comes from C to A, can take connecting flight A to B. I only know, for example, that the minimum connection time at A is one hour. Do I need to put 1 hour on TOP of the segment time, or is the ground time (already included in segment time) considered part of the connection time?

E.g. does the time between "Arrival time" and "Ready for departure time" consider part of the passanger transfer time?

Example:

C to A

departs 0100 pm -> arrives 0320 pm (ready for deparure 0400 pm)

segment time blocked in scheduling is 0100 pm to 0400 pm

At what time can I schedule connecting flight (A to B ), so passanger from C can connect to a flight to B, after arriving at point A?

For example, here we are talking about the same aircraft.

As far as I know, if the transfer time is 40 minutes, all passengers require that minimum time to go from one plane to another.

Example:

"Airport A" has a transfer time of 40 minutes.

"Airplane #1" lands at "Airport A" at 12:00pm, and is scheduled for another flight at 12:40pm.

"Airplane #2" lands at "Airport A" at 12:05pm, and is scheduled for another flight at 12:45pm.

Passengers can move from "Airplane #1" to "Airplane #2", because the difference in arrival/departure times is equal to or greater than 40 minutes -- in this case, it's 45 minutes.

However, passengers cannot move from "Airplane #2" to "Airplane #1" to depart at 12:40pm, because they don't have the minimum time (40 minutes) between their arrival and "Airplane #1"s departure time of 12:40.

Sorry it's not exactly answering your question, but I got a bit confused and thought it better to try and solve it this way.

By "Airplane #1" lands at "Airport A" at 12:00pm do you mean the arrival time as listed in the table (with the green OKs) when you schedule the flight, or by the end of the block/segment time?

Hi,

transfer time starts when the plane has landed, not when the plane is ready again for its next flight.

Turnover time of a plane can be different from airport to airport. If in doubt, check the aircraft performance tool on the manufacturer's page.

Once again, the turn around time of AC has nothing to do with passengers' transfers. While minimum transfer time (differ from small to large airports) is the minimum connection time for passengers to transfer from a flight to another flight. Although you are using the same AC, you have to reach the minimum transfer time in order for passengers to transfer. As you said, your AC arrives at 3.20 and so your passengers would probably transfer to your next flight/s at 4.00 (if the minimum transfer time is 40 minutes).

You can choose to depart at 4.00 although your AC has turn around time of 30 minutes. This can be useful for a small hub but not a large airport.

Although you are using the same AC, you have to reach the minimum transfer time in order for passengers to transfer.

That is not correct. If you use the same aircraft, the minimum transfer time is 0 as the passenger/freight will stay on board.

May be you have misunderstood what I said. The same AC does not refer to passengers staying on the same AC, but while he is scheduling the same AC with 2 different routes which then passengers from different flights/AC may need the minimum transfer time.

ok, in this case you are right ;)

The arrival time of the aircraft listed in the Route Management (or other pages). If you are speaking of the Scheduling table for that particular aircraft, remember the time in each green box (each flight) has included with it: takeoff, air flight time, landing, and turnover time for that particular aircraft.

It's confusing and intricate. The best way I've learned to deal with it is use planes that have similar or equal turnaround times to the airports' transfer times as possible. Not always possible, but it helps keep time right in my head.

Am I right in assuming that time would still need to be allowed if one is trying to gain additional transfer passengers from other flights?

According to what I have read, if other flights arrived prior to that flight and arrived earlier than the minimum transfer time, then you would need additional ground time for the particular aircraft where you want to get connecting passengers into.
