Recovery from Unusual Flight Attitudes

The instrument-rating version tests the light-airplane IFH recoveries. The ATP version references AC 120-111 — the upset prevention and recovery training (UPRT) AC — and its skill element demands more than a recovery: identify the attitude (both nose-high and nose-low) by proper instrument cross-check and interpretation, then apply flight control, power input, and aircraft configuration in the correct sequence to return to a stabilized level flight attitude, all solely by reference to instruments (AA.IV.B.S1). The sequence is the graded item — and in a transport airplane the sequence comes from the manufacturer's procedure or the industry recovery templates, not from instinct.

An upset is an airplane in flight unintentionally exceeding the parameters normally experienced in line operations or training:

• Pitch greater than 25° nose up
• Pitch greater than 10° nose down
• Bank greater than 45°
• Or within those parameters but at airspeeds inappropriate for the conditions (AC 120-111, para 1-6a)

An unusual attitude is any unintended or unexpected attitude in instrument flight; an upset has defined parameters, includes stall events and overspeeds, and centers on unintentional situations that may lead to a startle effect — in training, an instructor-set 30° bank with 15° nose-up is an unusual attitude but not an upset (AFH ch. 5).

The recovery priorities, in order (AC 120-111, para 2-2e):

1. Manage the energy
2. Arrest the flightpath divergence
3. Recover to a stabilized flightpath

Two governing rules sit on top:

• When an upset is precipitated by stall, recover from the stall before initiating other recovery actions — the templates assume the airplane is not stalled (AC 120-111, para 2-2e and ch. 4 NOTE, pointing to AC 120-109 for the stall procedure)
• The manufacturer's procedures take precedence over the AC's templates (AC 120-111, para 4-2 NOTE)

The templates themselves were built by Airbus, ATR, Boeing, Bombardier, and Embraer to give commonality across types (para 4-1).

Either pilot recognizes and confirms the developing situation and announces "Nose High." Then the pilot flying:

1. AP — DISCONNECT (expect a possible large out-of-trim condition)
2. A/THR — OFF
3. PITCH — apply as much nose-down control input as required to obtain a nose-down pitch rate (may take full nose-down; use nose-down trim if sustained column force is needed)
4. THRUST — adjust if required (consider reducing thrust on underwing-engine airplanes to aid the nose-down pitch rate)
5. When airspeed is sufficiently increasing — RECOVER to level flight, targeting a slightly nose-low attitude to avoid entering another upset

WARNING: excessive use of pitch trim or rudder may aggravate the upset or cause high structural loads (AC 120-111, Tables 1 and 3).

Roll. If nose-down inputs are unsuccessful, pitch can be controlled by rolling the airplane — a large bank angle helps reduce excessively high pitch attitudes, though the bank should not normally exceed approximately 60°. Continuous nose-down elevator keeps the wing's AOA low, which keeps the normal roll controls effective, and the rolling maneuver converts the pitch rate into a turning maneuver, letting the pitch fall (AC 120-111, Table 3). As the nose approaches the horizon, roll back to wings level, check airspeed, and adjust thrust and pitch.

Either pilot announces "Nose Low." Pilot flying:

1. AP — DISCONNECT, A/THR — OFF
2. RECOVER from stall if required — even nose-low and slow, the airplane may be stalled at a relatively low pitch, and the fix is nose-down elevator, which may not be intuitive
3. ROLL in the shortest direction to wings level — do not increase positive G or feed in nose-up elevator or stabilizer trim until approaching wings level; it may be necessary to unload (reduce back pressure) to improve roll effectiveness, and past 90° of bank unloading may feel like pushing
4. THRUST and DRAG — adjust: airspeed low, add thrust; airspeed high, reduce thrust and extend speedbrakes if necessary
5. RECOVER to level flight, avoiding stall from premature recovery or excessive G loading (AC 120-111, Tables 2 and 4)

The lift vector is both the recovery tool and the hazard: unloading is necessary to improve roll control and to prevent pointing a large lift vector toward the ground (AC 120-111, Table 4), but once the wings are level the instinct is to pull hard. The template's repeated warning: avoid stall from premature recovery or excessive G loading (AC 120-111, Tables 2 and 4).

At altitude the margins are thinner than they feel — increased G raises the low-speed buffet speed while cutting the margin below Mach buffet. A jet cruising at 51,000 feet with buffet boundaries at 0.60 and just above 0.82 Mach at 1.0 G can meet buffet at 0.73 Mach with only 1.4 G (AC 61-107, para 3-2). A smooth, measured pull is not timidity; it is the recovery.

• Pitch trim: sparingly. Use it to relieve sustained column forces, not to fly the recovery — recovery to level flight may require it, but excessive use of pitch trim may aggravate the upset or result in high structural loads (AC 120-111, para 4-2b and Table WARNINGs)
• Rudder: only if roll control is ineffective, and carefully — the same structural warning applies (para 4-2b)
• Anticipate the trim state: disconnecting the autopilot may hand you a large out-of-trim condition at the worst possible moment (Table footnotes)

MONITOR airspeed and attitude throughout the recovery and ANNOUNCE any continued divergence — the templates assign that line to the PM verbatim, and the explanation is blunt: evidence shows the PM is often in a better position than the PF to recognize adverse trends in airplane state (AC 120-111, Tables 3 and 4). Recognition itself belongs to either pilot — whoever sees it announces "Nose High" or "Nose Low." The AFH's crew-response standard adds: communicate and confirm the situation clearly and concisely, transfer control to the most situationally-aware crewmember, and work as a team through standardized interactions (AFH ch. 5).

• Environmental — turbulence from clear air, mountain wave, wind shear, thunderstorms and microbursts; wake turbulence from other aircraft; icing destroying the smooth flow over the airfoil (AFH ch. 5)
• Mechanical — failures that directly depart normal flight: asymmetrical flaps, malfunctioning or binding flight controls, runaway trim; and malfunction or misuse of the autoflight system, where advanced automation may mask the cause of the anomaly — disengaging the autopilot and autothrottles lets the pilot control the airplane directly and possibly eliminate the cause (AFH ch. 5)
• Human — VMC into IMC, diversion of attention, task saturation, sensory overload, and spatial disorientation (AFH ch. 5); the ACS compresses these into AA.IV.B.R1

The automation point carries a duty: maintain proficiency to manually fly the airplane in all flight conditions without the autopilot/autothrottles (AFH ch. 5).

Startle: an uncontrollable, automatic muscle reflex — raised heart rate and blood pressure — elicited by a sudden, intense event that violates expectations (AC 120-111, para 1-6p). Surprise: an unexpected event that violates expectations and can affect the mental processes used to respond (para 1-6q).

Upsets in line operations are unplanned, so startle or surprise can adversely impact recognition or recovery — which is why instructors deliberately build both into scenarios (AC 120-111, para 2-5m). Contrast the classic unusual-attitude drill where you close your eyes and any element of surprise disappears (AFH ch. 5). The countermeasure is a recovery sequence trained until it survives the reflex.

Proportional counter-response is the timely manipulation of flight controls and thrust to manage an unintended attitude or envelope excursion, on a time scale of seconds or fractions of seconds — recognizing a developing upset and taking proportionally-appropriate avoidance action before the airplane reaches full upset parameters (AFH ch. 5).

It prevents escalation by front-running the psychological risk: the AFH warns that the sudden, surprising nature of a developing upset creates a high risk of panic and overreaction that aggravates the situation. Two completion standards formalize the idea: recognition — timely action to recognize divergence from the intended flightpath and interrupt progression toward a potential upset (AC 120-111, para 2-2d); prevention — timely action to avoid progression toward a potential upset (para 2-2c).

• Reduced air density reduces aerodynamic damping, overall stability, and control — at high altitude and high Mach the airplane can simultaneously exhibit slow-speed problems like Dutch roll, adverse yaw, and stall (AC 61-107, para 3-3)
• The buffet margins converge: increasing gross weight or load factor raises the low-speed buffet speed and lowers the Mach buffet speed, and a maneuvering pull can erase a 1.4 G straight-and-level buffet protection entirely — any change in airspeed, bank, or gust load may reduce it to no protection (AC 61-107, para 3-2)
• Thrust is scarce: thrust available varies significantly with altitude — the AC's demonstration is timing how long a 25-knot level-flight speed change takes at low versus high altitude (AC 120-111, para 2-5l) — so energy mistakes cannot be bought back quickly

A pilot in a typical FSTD feels less than 10 percent of the actual airplane G, and pilot control inputs are highly influenced by load factor — so the sim systematically under-teaches how a real recovery feels (AC 120-111, App. 3, para 4). The same appendix warns that upset recoveries in an FSTD at high altitudes can be prone to oscillations that go unnoticed unless the full suite of displays is used. Say this in the oral and you demonstrate exactly the risk understanding AA.IV.B.R6 (control input errors) is probing: the airplane will load up in ways the box never showed you.

• Underwing engines — thrust produces a nose-up pitching moment, which is why the nose-high template offers reducing thrust as a tool for achieving a nose-down pitch rate, and why thrust is adjusted rather than firewalled (AC 120-111, Table 3); if pitch is being managed with trim and elevator, reducing thrust is not recommended
• Swept wings — tip-stall tendency moves the center of lift forward at high AOA, and the type-specific behaviors (Task IV.C) shape what the recovery feels like
• T-tails — susceptible types can reach a deep stall where the tail is immersed in the wing wake and loses effectiveness; high AOA can exist at any pitch attitude, even nose below the horizon, so the correct action — push further nose-down — may seem counterintuitive (AFH ch. 16)

The honest oral answer is type-specific: AC 120-111 directs carriers to consult the FSB report for the type, including its Training Areas of Special Emphasis on in-flight handling (para 3-2b).

• Incorrect assessment of what kind of upset the airplane is in — the templates begin with recognize-and-confirm for a reason; energy state and its rate of change drive how the PF handles the recovery (AC 120-111, Tables 3 and 4)
• Failure to disconnect the wing leveler or autopilot
• Failure to unload the airplane when necessary
• Failure to roll in the correct direction — shortest way to wings level
• Inappropriate airspeed management during the recovery

Each maps onto a risk element: assessment is AA.IV.B.R5, interpretation is R4, the control-input errors are R6.

Mostly after it — a recovery can leave the airplane well off its assigned altitude and heading. The AC's training-scenario emphasis names five items to reestablish situational awareness on while returning to the desired flightpath after the recovery (AC 120-111, App. 2):

• Heading
• Terrain
• Altitude
• Other aircraft
• Flight deck automation

The paired common error is losing situational awareness and failing to return to the assigned flightpath or follow ATC instructions after recovery (AC 120-111, App. 2). Two more traffic hooks: searching for traffic is on the AC's list of distractions that can lead to an upset in the first place, and overcontrolling for a TCAS resolution advisory is a pilot error that can itself create an undesired aircraft state (AC 120-111, para 2-5). Once stabilized: check TCAS, talk to ATC, get back on the clearance.

121.423, Pilots: Extended Envelope Training, whose required maneuvers include upset recovery maneuvers (121.423(b)(4)) along with manually controlled slow flight, loss of reliable airspeed, and instrument departure and arrival — all conducted in a Level C or higher full flight simulator (AC 120-111, para 3-2d). Recurrent extended envelope training on those items is required within 24 calendar months preceding service as a pilot (121.423(d)). Full-stall and stick-pusher training under the same rule is developed in the Area V tasks.
