This upgrade for the stock King Air is all about better flying – better and more realistic handling, and hitting accurate book numbers in all aspects.
- No plugins to ‘force’ the flight model.
- No hidden parts,.
- No cheating the sim.
Just absolute accuracy and careful tuning to get the full potential out of an X-Plane aircraft!
Important: This an upgrade of the stock C90B King Air that comes with X-plane 11. No other purchase is necessary to use it.
Product Summary:
C90B King Air with flight dynamics and specifications enhanced for maximum realism.
Aircraft performance improved to match book values with average accuracy across all test points of over 99%!
This upgrade utilizes the current and now very stable Experimental Flight Model option for maximum accuracy (X-plane 11.4x-11.5x).
No new graphics, systems, or sounds are included. This package is a set of new flight dynamics that connects to the stock C90B King Air that comes with X-plane.
The stock C90B King Air is remains available to you after EFM installation if you wish to use it. The EFM package adds a new aircraft to X-plane.
Highlights:
- Utilizes the existing King Air C90 graphics and sounds included with X-plane 11 by Laminar Research.
- Cruise speeds accurate across all altitudes and power settings.
- Accurate stall speeds, flap up or down.
- Correct rates of climb.
- Correct glide ratio.
- Accurate single-engine performance.
- Accurate take-off and landing distances.
- Accurate ‘feel’ and handling.
- Accurate fuel consumption at all altitudes and power settings (respect the torque redline!).
Some issues in the stock model corrected in the EFM:
- Engines not ‘de-rated’ to produce full-torque to over 10,000ft.
- Aircraft unable to achieve fast-cruise at high altitude due to insufficient engine torque.
- Take-off distance too long.
- Landing distance too short.
- Climb rate on a single engine 30% too low.
- Stall speed with flaps extended 12kts too high.
- Too-high L/D (aerodynamic efficiency) resulting in excessive glide performance.
- Aircraft too fast for given power settings (probably related to the previous point).
(Please note that this is NOT intended as a criticism of the stock Laminar model, it was likely more accurate when first created, but X-plane flight dynamics have evolved and improved considerably since then, including means of adding greater depth and realism).
