FlightFX updates Hawker 800XP to v1.6 on the Microsoft Marketplace

A core systems routine had been running at an unnecessarily high frequency and increasing main-thread load. v1.6 reduces that frequency to lower CPU burden. Geopol borders and city-name rendering that caused large stutters at certain locations were fixed.

The update adds direct mouse controls for the MFD and PFD to replicate CCP and DCP controls. These can be disabled via the EFB. The MFD CCP menu was updated to more closely match the real Hawker 800XP layout and operation.

Terrain rendering on the MFD was improved to resemble the Pro Line 21 display, including highest/lowest terrain elevation readouts. Brightness controls that could dim or blank displays when entering clouds were fixed. The ESIS backup display brightness has been reduced by 50% at night and now returns smoothly to daylight levels as ambient light rises.

A ground-only shortcut was added: triple-clicking the elevator trim wheel sets takeoff trim for the aircraft's current center of gravity. There's also a new click spot for toggling Active Noise Reduction on the headset port, and the lavatory seatbelt sign now follows seatbelt-logic rules.

SimBrief transfers to the FMC now populate the runway field. Several issues that affected flight-plan sequencing and approach/runway synchronization were corrected, including cases where an approach had to be entered twice for performance data to appear. The update adds manual runway entry on the approach performance page for approaches without an assigned runway.

Issues fixed include ILS autotuning retaining previous approach frequency, unexecuted flight-plan changes affecting LNAV guidance, and flight-plan recalculations that used outdated heading and bank data. GCS buttons on the MFD now restore previous states correctly when pressed again.

The simulator's AUTO THROTTLE DISENGAGE command now disconnects the Hawker's ATS. The ATS respects the thrust-rating selected on the THRUST LIMIT page as its maximum in all modes. The update fixed flight-director guidance that had been holding the aircraft below the glideslope in strong headwinds by addressing a glideslope director limit.

Pilots who use the Hawker for regular flights will see smoother performance, more reliable avionics interactions, better flight-plan and VNAV behavior, and a few added conveniences (mouse control, trim shortcut, headset noise control). Several edge-case bugs related to displays and guidance were corrected, improving day-to-day usability.

If you fly the Hawker 800XP in MSFS 2024, installing v1.6 is likely to reduce stutters and address several nuisance issues that affected avionics and VNAV accuracy.
