Excerpt from Threshold

Synaptic Simulations has just released an update for their A220 aircraft in Microsoft Flight Simulator 2020 and 2024. This update upgrades the aircraft to version 1.0.4 and introduces a variety of fixes related to the systems, artwork, EFB, and flight model, which significantly enhance the overall experience. Notable improvements include a reduction in display texture size, cabin draw calls, mesh vertices, and model node count, all contributing to better performance.

The update includes a detailed changelog, which is outlined below:

v1.0.4

Systems

Fixed – General pass over the ND and EICAS to make improvements to performance

Fixed – Slightly adjust FMS cross-track gains when en-route and on approach 1

Fixed – Starting engines with throttles set to max causes crazy N1/N2/EGT values

Fixed – APU start sequence broken when door opens before start request is commanded

Fixed – Ailerons droop the wrong way in windy conditions

Fixed – CI legs with no course change draw loop on the map

Fixed – CI legs find intercepts on the other side of the world

Fixed – VA legs incorrectly treated as vectored when computing discontinuities

Fixed – VM legs incorrectly treated as unvectored when computing discontinuities

Fixed – IF legs not replaced with TF legs when clearing discontinuities 2

Fixed – Top-of-descent marker pinned to aircraft’s present position

Fixed – Turn arcs and intercept arrows are not always drawn correctly on the map

Fixed – PFD displaying date one day ahead

Fixed – PFD vertical and lateral deviation preview pointers using wrong icon for FMS source

Fixed – Map OVLY task menu should time out after 2 seconds

Fixed – Altitudes swapped when entering between altitude constraints into FMS

Fixed – Missing runways in custom sceneries that would use “Macadam” or “Undefined” as surface types

Fixed – FLAPS HANDLE INDEX variable not set to current detent 3

Fixed – AUTOPILOT ALTITUDE LOCK VAR variable not set to current preselector altitude

Fixed – Checklist RESET ALL function should only be selectable from index pages

Fixed – Checklist INLET_OFF variable state flipped

Fixed – VHF frequencies rounding down when set externally or when switching channel spacing

Fixed – OFF indication missing on avionics cooling inlet switch

Fixed – Incorrect relative altitude shown for TCAS traffic

Fixed – Procedure identifiers on FMS PLAN INIT page not cleared when corresponding segment is deleted

Fixed – Several incorrect indications on the AIRCRAFT…
