FAA Recreational Pilot - Airplane (RPA) key terms

A Federal Aviation Administration pilot certificate that lets a person act as pilot in command of a small single-engine airplane carrying no more than one passenger, without compensation or hire, under the limits in 14 CFR Part 61 Subpart D.

The person aboard the aircraft who is directly responsible for its operation and safety, with final authority over the flight. The pilot in command may deviate from regulations in an emergency to the extent needed for safety.

An authorization placed on a pilot certificate that names a class of aircraft within a broader category, such as single-engine land. A recreational pilot may fly only the class listed on the certificate.

Two levels used to group aircraft. Category groups by broad design, such as airplane, rotorcraft, or glider; class groups within a category, such as single-engine land or sea. Ratings are issued at both levels.

A required review of aeronautical knowledge and flight maneuvers with an authorized instructor, normally every 24 calendar months, that renews a pilot's privilege to act as pilot in command of an aircraft.

The flight time and training a pilot must document to qualify for a certificate or rating. For a recreational pilot certificate this includes logged instruction, solo flight, and cross-country time as specified in the regulations.

A signed entry by an authorized instructor in a pilot's logbook or training record that certifies specific instruction, competence, or preparation has been completed, such as sign-off for solo flight or a knowledge test.

Flight time during which a student or pilot is the sole occupant of the aircraft. Solo flight requires instructor authorization and, for students, specific endorsements and medical or alternative documentation.

A document issued after an examination by an aviation medical examiner that states a pilot meets the health standards for a given class. A recreational pilot generally needs at least a third-class certificate or an accepted alternative.

An alternative to holding a traditional FAA medical certificate that lets eligible pilots fly certain small aircraft after a physician's examination and a required online course, subject to specific operating limits and aircraft weight restrictions.

A pilot's personal judgment, before each flight, that they are physically and mentally fit to fly, considering illness, medication, fatigue, alcohol, and stress. It applies even when a formal medical certificate is held.

A preflight personal check of Illness, Medication, Stress, Alcohol, Fatigue, and Emotion or Eating. It helps a pilot decide whether they are fit to fly and supports the self-certification required before flight.

A condition in which body tissues receive insufficient oxygen. In aviation it can result from high altitude, shallow breathing, or carbon monoxide exposure, and it impairs judgment before the pilot notices symptoms.

A hazard caused by inhaling colorless, odorless exhaust gas, often from a cabin heater leak. Symptoms include headache, dizziness, and drowsiness, and the pilot should shut off the heater, open vents, and land as soon as practical.

A pilot's mistaken perception of the aircraft's position or motion, often when outside visual references are lost. The reliable remedy is to trust and cross-check the flight instruments rather than bodily sensations.

False sensations of turning, tumbling, or tilting produced by the inner ear's balance organs during acceleration or abrupt attitude changes. They are most dangerous in low visibility, when instrument reference is essential.

Regulations that govern flight when the pilot can see and avoid other aircraft and obstacles, requiring specified visibility and cloud clearance. A recreational pilot is limited to flying under these rules.

Weather conditions equal to or better than the minimum visibility and cloud clearance required for visual flight rules. Pilots must remain in these conditions unless holding an instrument rating and clearance.

A lettered category, from A through G, that defines the rules, equipment, and pilot qualifications required in a given volume of airspace. Classes B, C, and D require specific communication and clearance procedures.

An airborne radio device that replies to radar interrogations with a squawk code and, in Mode C or S, altitude information. It supports traffic separation and is required in certain airspace.

A continuous recorded broadcast of current weather, active runway, and field conditions at an airport, updated periodically and identified by a phonetic letter that pilots report when contacting controllers.

The radio frequency 121.5 MHz, monitored for distress calls and emergencies. Pilots may use it to declare an emergency or request assistance when other communications fail.

A document issued by the FAA certifying that an aircraft conforms to its approved type design and is safe to operate. It must be aboard the aircraft and remains valid while maintenance and inspections are kept current.

An FAA approval of an aircraft's basic design, including its limitations and approved configurations. Production aircraft must conform to this design to receive an airworthiness certificate.

Legally mandatory maintenance or modification instructions issued by the FAA when an unsafe condition exists in a product. Compliance is required and must be documented in the aircraft records.

A complete inspection of the aircraft and its components performed at least every 12 calendar months by an authorized inspector or repair station, required to keep the airworthiness certificate valid.

Simple, minor preservation work and part replacement that a pilot may perform on an aircraft they operate, as listed in the regulations, provided the work does not involve complex assembly or major alteration.

The calculation confirming that an aircraft's total weight and center of gravity fall within approved limits for a given flight. Exceeding limits degrades performance and control and may make the aircraft unairworthy.

The point where the aircraft's total weight is considered concentrated. Its position must stay within a forward and aft range; an out-of-range value changes stability and control forces.

Pressure altitude corrected for nonstandard temperature. High density altitude reduces engine power, propeller thrust, and wing lift, lengthening takeoff and landing distances and reducing climb performance.

The altitude indicated when the altimeter is set to the standard datum of 29.92 inches of mercury. It is used for flight levels and as the basis for computing density altitude.

The local barometric pressure value, in inches of mercury, entered into the altimeter so it displays height above a reference datum. Setting it incorrectly causes the aircraft to fly at unintended altitudes.

A routine coded report of observed surface weather at an airport, including wind, visibility, clouds, temperature, dew point, and altimeter setting. Pilots decode it to assess conditions before flight.

The height above ground of the lowest broken or overcast cloud layer, or of an obscuring phenomenon. It is a key element in determining whether visual meteorological conditions exist.

A loss of lift that occurs when the wing exceeds its critical angle of attack, regardless of airspeed or attitude. Recovery requires reducing the angle of attack, often by lowering the nose.

The angle between the wing's chord line and the relative wind. Increasing it raises lift up to the critical angle, beyond which the wing stalls.

Drag created as a byproduct of producing lift, greatest at high angles of attack and low airspeeds. It decreases as airspeed increases, which is why total drag has a minimum at a specific speed.

A gyroscopic instrument that shows the aircraft's pitch and bank relative to the horizon. It gives an immediate picture of attitude and is central to recovering from unusual attitudes or disorientation.

The required preparation before flight, including reviewing weather, fuel requirements, alternatives, and aircraft performance. It is a regulatory duty, not just good practice, and must be completed before every flight.
