Combine the flour, smoked paprika, garlic powder, cayenne pepper and salt in a large bowl.
Add the wings and coat well.
Place in the fridge for 1 hour.
Spray your air fryer basket with non-stick spray.
Preheat your air fryer to 400 F.
Add the wings to the air fryer. Do not overlap.
Spray the wings lightly with more non-stick spray. If there are any 'floury' spots, give them an extra spray so that they crisp up good.
Bake for 10 minutes.
Gently turn the wings and lightly spray again with non-stick spray. If there are still some 'floury' spots, give them an extra spray so that they crisp up good.
