FAA MEI key terms

A published departure route or climb gradient that lets a pilot avoid obstacles after takeoff when standard climb performance is not enough. It may be flown only under the conditions stated on the chart.

The ratio of altitude gained to horizontal distance flown, usually expressed in feet per nautical mile. It differs from climb rate because it accounts for groundspeed and wind, and it drives obstacle clearance planning.

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

The altitude indicated when the altimeter is set to 29.92 in Hg. It is the basis for aircraft performance charts and for flight levels at and above the transition altitude.

The altitude at or below which pilots set the local altimeter and above which they set the standard setting of 29.92 in Hg. It varies by country and is published on charts.

The local station pressure value dialed into the altimeter so the instrument shows height above mean sea level at the reporting point. An incorrect setting causes the aircraft to fly higher or lower than indicated.

The charted limits of total weight and center of gravity within which the aircraft is approved to operate. Flying outside it can reduce controllability and increase structural loads beyond certification limits.

The point where the aircraft's total weight is considered concentrated. Its fore and aft position affects stability, stall recovery, spin behavior, and takeoff and landing performance.

The difference between maximum certificated takeoff weight and empty weight. It includes fuel, oil, passengers, baggage, and any removable equipment the flight needs.

The weight of the aircraft and all contents except usable fuel. It is a structural limit on some aircraft because fuel stored in the wings offsets bending loads.

The engine whose failure would most adversely affect performance or handling, historically the left engine on conventional twin-engine aircraft because of P-factor and asymmetric thrust.

The minimum control speed in the air, the slowest speed at which the aircraft can be kept under control with one engine inoperative and the other at takeoff power, with the critical engine failed.

A training maneuver in which the instructor has the pilot slow the aircraft toward Vmc with one engine at zero thrust, showing the loss of rudder authority and the onset of directional divergence.

The maximum density altitude at which the aircraft can maintain a 50-foot-per-minute climb with one engine inoperative and the other at maximum continuous power.

The gradual loss of altitude while flying on one engine at a speed that cannot sustain level flight. Pilots plan a drift-down profile to reach a suitable airport or an engine-out altitude.

The runway length needed to accelerate to decision speed with all engines operating and then stop after a failure, using maximum braking and, on some aircraft, reverse thrust.

The runway length at which the accelerate-stop distance equals the accelerate-go distance to 35 feet. It is a certification and planning concept for multiengine takeoff performance.

A simulated engine failure setting in which the propeller of the inoperative engine is set so it produces negligible thrust and drag. It lets the pilot practice single-engine handling without shutting down the engine.

Rotating the propeller blades to an edge-on angle that minimizes drag when an engine stops. It reduces the asymmetric drag that otherwise degrades single-engine climb and control.

The best single-engine angle-of-climb speed. It gives the greatest altitude gain over horizontal distance and is used to clear obstacles after an engine failure.

The best single-engine rate-of-climb speed. It yields the greatest altitude gain per unit of time and is the target speed in most single-engine climb profiles.

A spoken three-way procedure in which one pilot says 'You have the controls,' the other acknowledges 'I have the controls,' and the first confirms. It prevents confusion about who is flying.

The practice of deliberately removing or postponing nonessential tasks during high-workload phases so attention stays on flying and decision-making, a core element of single-pilot resource management.

The instructor's deliberate process of identifying hazards in a training flight, weighing their likelihood and severity, and applying controls before and during the lesson.

A systematic approach to choosing among alternatives in flight by recognizing hazards, assessing risk, and applying countermeasures. It is taught as a repeatable process rather than intuition.

A pilot's accurate perception of what the aircraft, environment, and crew are doing, and what that means for the near future. It degrades gradually and is often noticed only after a surprise.

The condition in which workload exceeds the pilot's capacity to handle it, causing tasks to be dropped or rushed. Instructors should build workload gradually and teach prioritization.

A temporary pause in apparent progress during flight training, often after initial rapid gains. It is normal, and instructors respond with varied practice, rest, and encouragement rather than more repetition.

The effect of prior learning on new learning or performance. Positive transfer helps when skills share common elements; negative transfer occurs when old habits interfere with new procedures.

Instruction built around realistic, decision-rich situations rather than isolated maneuvers. It develops judgment and lets the instructor observe how the pilot applies knowledge under workload.

A written preflight briefing outline that states the objective, completion standards, required knowledge, and sequence of a maneuver. It keeps instruction focused and makes evaluation consistent.

The observable criteria that define acceptable performance of a maneuver, stated in terms of altitude, airspeed, heading, and bank tolerances. They tell the pilot when the objective has been met.

An instructional technique in which the instructor explains and demonstrates a maneuver, then the pilot performs it while the instructor observes and corrects. It is standard for flight maneuvers.

A maximum-performance climbing turn through 180 degrees that begins at cruise speed and ends near stall speed. It develops coordination and planning of bank, pitch, and power.

A maneuver tracing two 180-degree climbing and descending turns in which airspeed and altitude change continuously. It teaches feel for coordination, energy management, and planning ahead.

A level turn of 45 degrees bank or more, in which load factor and stall speed increase sharply. It trains smooth control input, back pressure, and power coordination.

The named segments of the airport traffic pattern: upwind, crosswind, downwind, base, and final. Standard entry calls and positions depend on knowing these legs precisely.

A pattern with left traffic replaced by right traffic, or with an unusual shape, published for noise abatement or terrain. Pilots must brief the difference before entering.

Any unauthorized presence on a runway, whether by an aircraft, vehicle, or person. It is a leading cause of serious accidents and is avoided by clear communications and sterile cockpit discipline.
