Atom interferometers have demonstrated excellent performances in the field of high precision inertial measurements. Foreseen applications include terrain measurements (inertial navigation, geophysics, oil prospection...) and tests of fundamental physics. In this respect we are developing a dual species atom interferometer in order to carry out a test of the Universality of Free Fall (UFF) onboard an aircraft carrying out parabolic flights. We have already demonstrated that it was possible to operate an atom interferometer in an aircraft, reaching very high acceleration sensitivities (up to a few 10-5g) by rejecting the plane's vibration noise.
