World 3501
Airline 16069
Aircraft 5955 (Although all 707-320s have this problem)

There seems to be a miscalculation for the Boeing 707-320 where block times are the exact same or higher as much slower aircraft, even accounting for turn time.

See comparison below for a Lockheed Electra and 707.

Depart   PEK Beijing Capital International   
Arrive   SGN Tan Son Nhat International; Ho Chi Minh City   
Distance   2,114nm
Aircraft Details   
ID   Aircraft   Speed   Range   Freq   Block Time
5955   Boeing 707-320   541   6,610nm   1.5   7:54 (7.90 hours)

Depart   PEK Beijing Capital International
Arrive   SGN Tan Son Nhat International; Ho Chi Minh City
Distance   2,114nm
Aircraft Details   
ID   Aircraft   Speed   Range   Freq   Block Time
6214   Lockheed L188 Electra   352   2,507nm   1.5   7:09 (7.15 hours)

Additionally, there's a discrepancy in construction time between the 707-320 and the 707-420--the former is 96 days and the latter is 72. There's no discernible difference between the size of the aircraft!

Which engines does the 707 have? Turbojet aircraft have a bug in the game leading to excessively long block times, but a fix is in the works.

The construction time I don't know, it's usually calculated automatically when creating the aircraft in the database.

The block time issue occurs in newer worlds due to changes in how we handle supersonic aircraft. I put a fix around turbojets so that slower aircraft (like the 707) are handled like a turbofan but faster aircraft (Like the Concorde or TU-144) are handled correctly. The fix will be in-game when we do our new big feature release which is order books.

We can swap out your 707-320's for another 707 variant if you like, that should allow you to create routes as you wanted to despite the issue with block times. The 707-320B has turbofan engines and will produce normal block times.

Looking at the 707-420 stats on the back end, it should probably be a 96 day construction length rather than a 72 day one. As Matias said it is an automated calculation and sometimes older data remains in the database where we changed the construction length formula but didn't update all the aircraft at once.

Would it be possible to replace them with 707-420s?

All set, the 707-320s have been switched over to the 707-420, I put the letter A on the end of the name so you can see which ones we modified.

Go ahead and edit each route to get the block time to be re-calculated. No need to cancel and re-create or swap aircraft, just updating the fares is enough to fix the blocks. N112ZR (ID 3536) is the example I used to get the blocks back to normal.

Let us know if you run into any other difficulties!

Thanks Stephen! I have deliveries of 7 more brokered -320s coming in the next few days that were previously ordered plus two that were just delivered. Should I ping you when they are "on property?"

Is this issue also a problem for the 720? I've now cleared out my order book of 707-320s and they need to be converted to -420s.

Thanks!

I think it depends on if they are turbojets or turbofans

All set with the latest 707-320s.

For the Boeing 720s, looks like the normal 720 has turbojet engines while the 720B has turbofans. I can swap those around as needed as well. I think due to the time period of this world we notice the turbojet/turbofan issue more than other worlds.
