Due to the operating regime of very light jets, an assumption must be made that very little distinction might exist between a VLJ weighing 10,000 pounds or less and heavier corporate jets. The VLJ will weigh less than many popular turboprop cabin-class twins yet will be capable of operating near the upper limits of civilian airspace as well as being integrated into the traffic patterns of America’s high-density airports. The Air Traffic System and the owner-operators must recognize the vulnerability of these lightweight and high-performance aircraft.

The manufacturers of VLJs have started to look at the unique risks that exist for their products. Any training proposal put forth by the manufacturer or vendor must include an understanding of these potential problems and the intent to address them in all phases of the training plan. The following is a list of issues discussed and brought forward during VLJ manufacturer visits:

  • Wake turbulence encounters
    • At altitude and in the traffic pattern
    • In-trail spacing and profile adjustments
    • Best recovery configuration
  • Convective weather encounters

    • Alternate route identification
    • Contract flight planning and/or dispatch interaction
    • Circumnavigation fuel capability
