To retrofit some of the upgrades of HondaJet Elite to pre-Elite HondaJets, an APMG (Advanced Performance Modification Group) upgrade is available for $250,000. This includes 100 to 120 nmi range increase,[57] and a 45 kg (99 lb) MTOW increase and take-off run reduction by 135 m (443 ft) to 1,064 m (3,491 ft); this is achieved by a few inches span extension of the horizontal tailplane, and removal of wing fences and vortex generators.[58] Avionics upgrades include takeoff and landing (TOLD) calculations, Flight Stream 510 wireless gateway compatibility, an enhanced electronic checklist, angle-of-attack indicator on the PFD, and visual approaches.[57] On the other hand, HondaJet Elite features such as an additional fuel tank or engine inlet acoustic improvement, are not available with APMG.[59]
