Info and Pricing


The Amp is a two-seat electric Special Light-Sport Aircraft (SLSA).  The design is for a super quiet (<65 dBa), comfortable, safe, efficient and green aircraft. We are making this possible by combining the new battery technology with the latest aircraft innovations.

Many Different Uses

The Amp is designed to fit in many different aspects of flying, some of which include:

  • Flight training – the Amp is an excellent training platform, providing over an hour of takeoffs and landings with time left to spare before needing to re-charge.
  • Leisure flight – take your Amp for a flight to another local airport and not go broke in the process.  With direct operating costs less than $10/hr*, the term “Hundred-dollar hamburger” will soon be a forgotten joke of the past.
  • Noise-sensitive flight operations –  with the whispering-quiet propeller, the airplane can be used in noise-sensitive areas without too much impact on wild life.
  • Remote operations – with optional solar-powered remote charging equipment, there’s no more need to supply fuel, or even electricity to the aircraft’s home base**.

* Based on current US electricity rates, the current battery costs, and the average flight of 50 hours a year or less.
** Will require a minimum of 4 hours of sunshine per day to operate.

A New Definition Of Comfort

The Amp has a 46-inch wide cockpit, along with an extremely quiet environment, comparable to that of a car.  No more need for headsets!

A Truly Remarkable Airframe Design


The Amp features a super-light composite airframe, which is built from a special new type of carbon fabric.  The advancements in the carbon composite technologies has allowed us to create a super light, yet super strong airplane.

Prior to now, most airframes have been designed to fit the needs of the gas-powered engines.  Alternair’s approach to the airframe design was to maximize the performance for the least amount of energy spent.  Our airframe has the maximum L/D at a slightly higher speed of 75 knots, and is capable of up to a 90-knot cruise in the nominal power setting range.  However, the airplane still has the low-speed handling characteristics similar to most modern gas-powered LSAs.

Next Generation of Advanced Systems

The Amp has a new feature never seen before on small General Aviation airplanes – an Aircraft Health Management (AHM).  This new feature is allowing us to help you, the operator, better understand what is going on with your airplane.  The AHM is also one of the reasons why we are able to offer a 5-year limited warranty at no extra cost (restrictions apply).
