<p>A method of controlling a buoyancy system for an aircraft includes: determining the roll angle phi and the pitching angle theta of the aircraft; verifying whether -phiR <+R and whether -thetaR <theta<+thetaR, where phiR and thetaR are predefined limit angles; if at least one of the angles phi and theta is no longer in its above-defined respective range, activating an automatic trigger of the buoyancy system; if the angles phi and theta are in their above-defined respective ranges, determining the altitude A of the aircraft; inhibiting the automatic trigger if A >AR, where AR is a predefined limit altitude; and if AR >=A, and if at least partial immersion of the aircraft has been detected, activating the automatic trigger.</p> |
