Here are some preview images from Stairport Sceneries and their upcoming scenery of Zagreb Airport for X-Plane 11:

Zagreb Franjo Tudman Airport or Zagreb Airport is an international airport serving Zagreb, Croatia. It is the largest and busiest airport in Croatia. In 2019, it handled 3.45 million passengers and some 13,000 tons of cargo.T he current terminal building was opened to the public on 28 March 2017.

X-Plane Developer: Locking Airports On The Gateway

Pin It

If you've been experiencing frustration with the airport locking mechanism on the Gateway, it's probably my fault! The logic behind this feature was changed recently and it kinda caught us out. All of this deserved an explanation, and some further tweaking from us to make things better.


To protect against two artists working on the same airport, some time ago we introduced the capability to "lock" an airport on the Gateway (for the duration of its development cycle). Originally this feature was unlimited, but was later revised to restrict the number of simultaneous locks that could be taken.

Recent Changes

The original locking mechanism was better than nothing, but not much. There was no intelligence behind it, that is to say, nothing to prevent an artist from holding an airport indefinitely (by releasing and renewing the lock) and no taking into account previous submission history for a given artist. As a result, we sometimes heard from frustrated artists that a certain high profile airport was being held for a silly long time by a newbie. Another source of frustration was not being able to lock enough airports to keep busy, a direct result of us trying to solve an earlier problem that artists were occasionally holding too many airports!

So, we brainstormed a new design that took into account each artist's skill set and submission history. Higher skill sets = more airports that can be locked, more and longer extension periods. Locking an airport and then abandoning it without making a submission = fewer airports that can be locked, fewer and shorter extension periods. I signed off on the new design and Daniela (as always) did a beautiful job coding it to the exact specifications.

Shortly after we went live there was a noticeable drop in Gateway submission levels. This sometimes happens, and I attributed it to the normal ebb and flow. However, it has since become apparent there is more to this. The new "locking" mechanism that was supposed to make things better and fairer was having the opposite effect. At first I could not understand this–surely artists don't need to lock more airports than they can simultaneously work on? But of course this is wrong! The problem is that, during the wait period between submission and moderation, the airport must remain locked, and hence an artist potentially needs to hold onto a bunch of airports that are "in limbo". No doubt everyone in the community already knew this, but I failed to take it into account when signing off on the new logic.

The Solution

The solution is to not tally airports that are waiting "in limbo". This means as soon as you submit your airport, it is no longer tallied against your lock total (but is still locked in an absolute sense, and therefore cannot be claimed by another artist). One thing to be aware of – when an airport becomes approved or declined, it ceases to be in limbo, and WILL be tallied against an artist's lock count. It's important therefore to manually release locks that are in effect, but no longer needed.

If you're reading this, it's already done. Things should be a little better!

Pin It

Supercritical Simulations Group (SSG) continues to improve their 747-8 for X-Plane with the release of v2.3. This update includes a long list of improvements and fixes to the external model, cockpit, systems, FMS, tablet and manuals.

Version 2.3 of the 747-8 for X-Plane improvements and fixes include:

External Model

  • FPS improvements, especially in Vulkan/Metal but also works well in OpenGL.
  • The complete external model was revised and many new UV fixes were made.
  • Fixed an error where the magenta track was off-center when the ND range was set at less than 2.5 miles.
  • Complete a new set of PBR textures.
  • New custom-designed external lighting.
  • Added Freighter main deck lights.
  • Added working Ram Air Turbine (RAT) and logic/systems.
  • Added electrical system dependency to certain cargo door operations.
  • Added details to the landing gear.
  • Improved particle system, including added fuel jettisoning and potable water draining.


  • Improved internal lights.
  • Fixed CDU and general instrument brightness.
  • Added crew lavatory to Intercontinental.
  • Added crew rest to Intercontinental.
  • Some texturing fixes were made.
  • Added more button sounds and animations.


  • Added RAT to the hydraulic system.
  • Added the second GPU for better system behavior.
  • Updated the automatic connection between electrical sources and bus ties.
  • Updated fuel, hydraulic, electrical, and other synoptic pages.
  • Improved the EICAS advisory message behavior and reset button function.
  • Added/revised fuel advisory messages.
  • Added emergency lights message.
  • Fixed engine #3 starting/shutdown logic.
  • Fixed and revised the external lights system and its power sources.
  • Updated behavior of the leading edge flaps and spoilers/speed brakes during all flight phases.
  • Added pitch limit indicators to the PFD.
  • Added fuel and electrical dependencies to APU starting.
  • Updated the wiper system to include independent control and added the cycle time for intermittent settings.
  • Updated some system sounds and added some new sounds for the improvements in this version.
  • Updated caution warning sound.
  • Fixed some manipulators such as vertical speed dial and autopilot disengage.
  • Fixed flaps up command for VREF + 100.


  • Increased the route legs list to 25 pages.
  • Fixed an error where the magenta track was off-center when the ND range was set at less than 2.5 miles.
