Regulation Text
§ 61.309 What aeronautical knowledge must I have to apply for a sport pilot certificate?
To apply for a sport pilot certificate you must receive and log ground training from an authorized instructor or complete a home-study course on the following aeronautical knowledge areas:
(a) Applicable regulations of this chapter that relate to sport pilot privileges, limits, and flight operations.
(b) Accident reporting requirements of the National Transportation Safety Board.
(c) Use of the applicable portions of the aeronautical information manual and FAA advisory circulars.
(d) Use of aeronautical charts for VFR navigation using pilotage, dead reckoning, and navigation systems, as appropriate.
(e) Recognition of critical weather situations from the ground and in flight, windshear avoidance, and the procurement and use of aeronautical weather reports and forecasts.
(f) Safe and efficient operation of aircraft, including collision avoidance, and recognition and avoidance of wake turbulence.
(g) Effects of density altitude on takeoff and climb performance.
(h) Weight and balance computations.
(i) Principles of aerodynamics, powerplants, and aircraft systems.
(j) Stall awareness, spin entry, spins, and spin recovery techniques, as applicable.
(k) Aeronautical decision making and risk management.
(l) Preflight actions that include—
(1) How to get information on runway lengths at airports of intended use, data on takeoff and landing distances, weather reports and forecasts, and fuel requirements; and
(2) How to plan for alternatives if the planned flight cannot be completed or if you encounter delays.

Research Notes — § 61.309 Aeronautical Knowledge for Sport Pilots
Scope of the Knowledge Areas
The § 61.309 knowledge areas are substantially similar to the private pilot knowledge requirements in § 61.105, but scoped to sport pilot operations. Key shared areas include weather, navigation, aerodynamics, emergency procedures, and ADM. The primary omission compared to § 61.105: no requirement for night flight knowledge areas (since sport pilots generally cannot fly at night). Source: 14 CFR § 61.105 — Private Pilot Aeronautical Knowledge.
Density Altitude — Mandatory Knowledge Area
§ 61.309(g) specifically calls out density altitude effects on takeoff and climb performance. This is not accidental — many light-sport aircraft have limited performance margins. High-altitude airports, hot days, and high humidity can dramatically reduce climb performance in LSA, which typically have smaller engines and lower horsepower-to-weight ratios than training airplanes. Source: FAA Density Altitude Safety Brochure.
ADM — Aeronautical Decision Making
§ 61.309(k) requires aeronautical decision making and risk management training. This reflects the FAA's recognition that most general aviation accidents stem from decision-making failures, not aircraft malfunctions. The sport pilot ACS integrates risk management elements into every task. Source: FAA Pilot's Handbook of Aeronautical Knowledge (PHAK), Chapter 2 — Aeronautical Decision Making.
Stalls and Spin Awareness
§ 61.309(j) covers stall awareness, spin entry, spins, and spin recovery — the same knowledge requirement that exists for private pilot certification. Sport pilots are not exempt from understanding stall/spin dynamics even if the practical test may not require spin demonstrations in all categories.
