For a short-field landing, the Airman Certification Standards (ACS) for the private pilot rating require that the applicant “Maintain manufacturer’s published approach airspeed or in its absence not more than 1.3 Vso, +10/-5 knots with gust factor applied.”
You’re about to land on a 1000-foot backcountry airstrip with an elevation of 3000 feet on an 80-degree F day. 1.3 Vso in your STOL- and VG-equipped Cessna 182 is 45 knots. At that speed you should be able to get down and stopped in 700 feet. There’s a decent margin for error—especially if you’re dealing with a tailwind on a one-way strip or slippery grass.
