there are a number of aircraft out there that have both anti and de-ice. 2/3 of the twins that I fly have anti ice in the form of a chemical release system and one them also has de-ice with inflatable boots.
The Cherokee 6 I fly has electric anti ice. The big problem is weight, all of these systems are heavy and subsequently need a lot of horse power.
The new Da42 twins that are being delivered to AFT at Coventry have chemical de-ice. Looking forward to flying them sat up in the airways on o2 at FL180!
