Latest updates
1.106
- Added Bell 412EPX
- Updated to use iOS SDK 26.0 per Apple requirements
- On the Edit Aircraft page, fixed a problem that would sometimes prevent the ability to edit certain items
if a Lateral Arm was not required (Internal: due to reused table cells)
- AS350 and AS355, clarified via comments that the Cargo Swing is Breeze Eastern 140127 or Siren S1609
and that Cargo Sling is Breeze Eastern 17149-1, per AS350 and 355 manuals.
- AS355NP altered the Swing Hook to be Onboard Systems 200-292-02 per Sup 11.
- Fixed an error with weight calculations for Firefighting Foam tanks
- Improvements to handling of Jettisonable loads: Loads such as firefighting water, that can be loaded and unloaded in flight are
handled in the same way as Suspended loads: they are shown (summed with the suspended loads) on a seperate line in the Longitudinal
and Lateral pages, and individually listed under "Suspended/Jettisonable Loads" section on the Data page.
Loads like Firefighting foam that are loaded pre-flight, but can be expended or jettisoned in flight are accounted for in the same way as
fuel and appear in the main line in the Longitudinal and Lateral pages, and individually listed in the "All Up"
section of the Data page.
- Added "Sikorsky S-70i FireHawk", with United Rotorcraft Firefighter Transport layout,
including Firefighting water tank and firefighting foam tank.
- Custom load stations can now be set as "Jettisonable" and/or "Inflight loadable".
