The Duncan Aviation /Garrett APU system interfaces with the aircraft’s electrical system and includes controls for operating, monitoring, and regulating the APU. As seldom as these systems fail, when they do, it can be confusing to determine which box is causing the problem.
As LITEF LCR-92/93 AHRS units become increasingly difficult and costly to support, legacy PC-12 operators need a practical way to address avionics obsolescence without a major flight deck upgrade.

Few business jets have had the staying power of the Dassault Falcon 900. More than 40 years after its first flight, the three-engine Falcon 900 remains a capable large-cabin business jet, thanks to decades of refinements to its engines, range, aerodynamics, and avionics. While the different 900 models may look similar on the ramp, their capabilities, maintenance needs, and market values can vary significantly. Understanding how each generation evolved—and what those changes mean for ownership—can help buyers make a more informed decision when considering a Falcon 900.

When an aircraft is parked in direct sunlight, the dark tint of sunshields absorbs heat and interior fold-out sunscreens reflect it back into the window. Both can damage the acrylic material on the window, causing irreparable and expensive damage.
If done on a routine basis, compressor washes will reduce deterioration of the ITT margin, help restore engine efficiency, reduce engine workload and decrease fuel consumption.
