I have made numerous searches, but nothing really answered the problem to the calculation I am trying to solve

From
https://wiki.airlinemogul.com/index.php/FAQ#How_can_you_calculate_block_time.3F

Airbus A320-200
Speed 469 (I assume nm/p/h)
Range 3504 nm
Turnaround time 0.72 (I assume is 0h43m)

Route
1071nm

Flight time calculates as route distance divided by speed
1071 / 469 => 2.28 hours or 2h17m

Block time calculation
"A one way flight can be calculated by dividing the flight length by the aircraft speed (e.g. 1000 miles / 500 miles per hour = 2 hours), then you have to add the turnaround time"

2.28 + 0.72 = 3.00 (3hr00m)

However AM has 3.61, a difference of 0.61

Other routes
220nm the difference is 0.67
1128nm the difference is 0.60
1545nm the difference is 0.64

What did I miss?

Hi there!

Welcome to the forum. Looks like we need to update the Wiki. On newer worlds where "Progressive flight paths and block times" are enabled the calculation has gotten a little more realistic.


The old method was a straight calculation of speed over distance, however in reality planes will travel at different speeds through flight. The calculation now reflects that as well as some additional milage flown through the air during departure and arrival sequences. The different stages of flight are loosely based on the following from Eurocontrol.

To find the time needed to fly a route before you buy gates or aircraft, check using the Research Route feature which should be able to calculate it for you.

Let us know if you have any other questions.

I was looking for a formula that I can use on an as and when required basis

I then discovered the link to the Updated block time in the FAQ, rather than just the plain calculation,
Research Route page
However it is dead

The Research Route menu adds a little work on a route by route basis

I used this before, all I get is the aircraft capable
There is no detail for the flight time or block time

I have now found it
The index of figures between the Speed and Seat
New: x.xx ,Old : x.xx

Glad you found it, it is a little hidden in there but each engine potentially has a different block time due to the speeds and engine technology.
