The leading airlines of the world have one key feature in common: fleet standardisation. What distinguishes One Air from other Spanish flight schools is that we have transferred this concept to our school by using exclusively next-generation Diamond aircraft for pilot training.

Our Fleet is composed of twin-engine DA42 Diamond and single-engine Diamond DA20C1 and DA40 aircraft. Used worldwide, they represent a benchmark in security. The US Air Force uses Diamond aircraft in the initial pilot training phases. Our Garmin 1000 Glass Cockpit avionics technology allows our students get used to the systems they will find in actual commercial aircraft.

You will learn to fly with the best fleet of Diamond aircraft: DA20 C1 Eclipse, DA40 GARMIN 1000 and Diamond DA42 GARMIN 1000.


The Diamond DA20 Eclipse is a two-seater, low-wing single-engine aircraft designed by Diamond Aircraft.

The flight control system of the DA20 is based on a control stick, while its cockpit offers great visibility to perform manoeuvres in total safety.

The fuselage is manufactured with carbon fibre and fibreglass (as in Formula 1 vehicles), offering great performance and safety in the cockpit.

The Diamond DA-20 C1 Eclipse has one of the highest glide ratios for this kind of aircraft at 14:1.

The C-1 Eclipse is the best equipped and has the most powerful engine within the DA20 range. Also, unlike other DA20 models, it has rear windows offering better visibility.

At One Air we have chosen the Eclipse model for all our DA20 single-engine aircraft. The aircraft is powered by a Continental IO-240-B engine, 125 hp (93 kW) which offers exceptional power-to-weight ratio thus achieving the best performance for this kind of aircraft.

  • Stall speed: 42 kn
  • Range: 1,013 km
  • Service ceiling: 13.123 ft
  •  Rate of climb: 1,200 ft/min

DA40 GARMIN 1000:

The DA40 G1000 is a four-seater single-engine model designed by Diamond Aircraft. The fuselage is manufactured with carbon fibre and fibreglass, as in Formula 1 vehicles.

At One Air we have equipped our aircraft with the latest technology so that you can fly in total luxury, including Garmin 1000, autopilot, radar, leather seats and much more!

 The DA40 has different variants depending on the engine. With us you will fly the most powerful model, which has a variable-pitch propeller and a fuel injected Lycoming IO-360-M1A direct injection engine.


  • Cruising speed: 147 kn
  • Stall speed (Vs): 51 kn
  • Range: 1,200 km
  • Service ceiling: 16,000 ft
  • Rate of climb: 1,200 ft/min

DA42 GARMIN 1000:

Our twin-engine Diamond DA42 aircraft have carbon fibre composite cockpits, just as Formula 1 vehicles. Our Platinum Edition aircraft are fully equipped with GARMIN 1000, autopilot, weather radar, TCAS anti-collision alert systems, TKS ice protection systems, long-range fuel tanks, FADEC digital engine control, etc…

As a fairly recent development, the first variant of the DA42 Twin Star was the first fixed-wing diesel-powered aircraft ever to perform a non-stop crossing of the North Atlantic. It flew from London to St. Johns (Ontario, Canada) in 7 and a half hours, and then to Oporto (Portugal), the entire flight taking 12 and a half hours.

Some variants of the DA42 are designed following specifications established by the UK’s Ministry of Defence, and the Swiss and Austrian air forces, which include surveillance systems equipment.
