500 and 550 and Bell models 205A1, 212 and Huey II.

Also added for in-production aircraft is a standard avionics listing. There are now 215 different models in the Aircraft Comparator, ranging from the Cessna 172 to the Boeing

757 to the Sikorsky S92.

The Aircraft Comparator contains performance charts, specifications, and interior and exterior drawings of fixed wing turbine, piston and rotary-wing turbine aircraft. For individual handbooks with software, prices range from $375 to $750, plus $50 per book charge for international orders.
