### Description

In the framework of the Future Circular Collider study, the option for an energy upgrade of the LHC is explored, the so called High Energy LHC (HE-LHC). To achieve the targeted 27 TeV, it relies on the use of 16 T dipoles, based on $Nb_3Sn$ and which are currently under development for the FCC-hh. At injection energy, the field quality of these dipoles is of major concern due to its large impact on the dynamic aperture. Here we present the results of the dynamic aperture calculations using the latest field quality estimates for different injection energies together with the employed nonlinear corrections schemes.
