VORTEX GNRTR CESSNA 401,A,B

Per the supplier: Yes, Micro VGs are STC approved for Cessna 172L. The VGs are located on the wings, the underside of the horizontal stabilizer, and on both sides of the vertical stabilizer. The VG kit is compatible with the leading edge cuff kits (Sportsman, Horton, Robertson, etc). Since the VGs work by energizing the airfoil you have, the combination reduces the stall speed from what it is with the modified wing, and in addition, it adds more crisp response to the elevator and rudder at those slow speeds.

Per the supplier: No. This product is not certified to change any weight carrying capacity in this aircraft.

Yes, the 337 form is included with the product.

Per the vendor: It depends on the aircraft. The registration number is required when special ordering this item to determine the qty req'd. They will span across the horizontal stab.

It is for the whole aircraft.

Per the manufacturer: "When an aircraft been modified in a way that results in additional wingspan such as with a WingX kit, Flint Tips, etc, we provide additional VGs and templates to accommodate this length at no additional charge if MENTIONED AT THE TIME OF THE ORDER."
