Straight-and-Level Flight

The Area XI note in the CFI ACS says the evaluator must select at least one Task from this Area of Operation. "At least one" means you cannot pick a favorite and ignore the rest — Tasks A through E are all in play, and E (unusual attitudes) is the one most likely to be paired with another because it is the only Task that starts with the airplane already out of shape.

Prepare A through D as one block: they share the same knowledge (K1: instrument limitations, attitude indications, function and operation, cross-check technique), the same eight risk elements (R1–R8), and the same tolerances — altitude ±100 feet, heading ±10°, airspeed ±10 knots (AI.XI.A.S2).

Prepare E separately. Its risk elements are its own — R1 situations leading to LOC-I or unusual attitudes, R2 assessment of the unusual attitude, R3 control input errors, R8 operating envelope considerations — and E.S1–S3 state no numerical tolerances at all. The standard there is identifying the attitude and applying control, power, and configuration in the correct sequence (AI.XI.E.S1). Do not walk in quoting ±100/±10°/±10 knots at an unusual-attitude question.

Because you will be teaching them. A private pilot applicant must log 3 hours of flight training in a single-engine airplane on the control and maneuvering of an airplane solely by reference to instruments, and 61.109(a)(3) names the syllabus: straight and level flight, constant airspeed climbs and descents, turns to a heading, recovery from unusual flight attitudes, radio communications, and use of navigation systems and radar services. That list is Area XI, in order.

Basic instrument maneuvers is also a required area of operation for the flight instructor certificate itself (61.187(b)(1)(xii)).

Yes. 61.195(l) allows a flight instructor to conduct training on control and maneuvering an airplane solely by reference to the flight instruments if the instructor holds a flight instructor certificate with the applicable category and class rating — a CFI-ASEL may teach the 61.109(a)(3) hood work in a single-engine airplane.

What you may not do without a CFII is conduct instrument training for the issuance of an instrument rating, a type rating not limited to VFR, or the instrument training required for the commercial and ATP certificates — that requires an instrument rating on the flight instructor certificate under 61.195(c). Know exactly where that line sits; the evaluator will push on it.

• The airplane must have fully functioning dual controls for flight instruction (91.109(a)); a throwover wheel is allowed for instrument instruction only if you determine the flight can be conducted safely and the person manipulating the controls holds at least a private certificate with appropriate ratings (91.109(a)(1)–(2)).
• Simulated instrument flight requires a safety pilot in the other control seat with at least a private pilot certificate and appropriate category and class ratings, adequate vision forward and to each side (or a competent observer supplementing it), and fully functioning dual controls (91.109(c)). As the CFI you are that safety pilot — which is why traffic scanning is not something you can delegate.
• On your own practical test you must supply the view-limiting device (61.45(d)(2)), and you and the evaluator brief when and how it goes on and comes off before the flight (CFI ACS, Equipment Requirements and Limitations).

1. Cross-check — the systematic, continuous observation of the instruments. Taught first because a scan cannot be corrected later; it is a habit.
2. Instrument interpretation — knowing what each indication means for this airplane at this attitude and power. Begins with understanding each instrument's construction and operating principles, then applying that to the airplane being flown (IFH 6-13).
3. Aircraft control — smooth, coordinated pressure applied to make the instruments say what you want.

Teach them in that order and diagnose errors in that order too: an inability to hold altitude is usually a scan problem or an interpretation problem long before it is a hands problem (IFH 6-12).

Both methods use the same instruments and the same control inputs; they differ in how much weight is placed on the attitude indicator (IFH 6-17).

• Control and performance — set attitude on the AI and power on the tach/manifold pressure (the control instruments), then confirm the result on the performance instruments (ASI, altimeter, VSI, HI, slip/skid). Navigation instruments are the third category (IFH 6-18).
• Primary and supporting — for each maneuver, one instrument gives the most direct indication of pitch, bank, and power; the others support it.

For a private student on 3 hours of hood time, teach control and performance. It is one sentence long — "set the attitude, set the power, then check the result" — and it survives task saturation. Introduce primary/supporting as the vocabulary for why the correction worked.

• Pitch — altimeter primary; attitude indicator, VSI, and ASI supporting.
• Bank — heading indicator primary; attitude indicator and turn coordinator supporting.
• Power — airspeed indicator primary; tachometer or manifold pressure gauge supporting (IFH 6-22).

The teaching point that makes it stick: the primary instrument is the one that tells you directly whether you are achieving the result you want, not the one you look at most. Altitude is the result in level flight, so the altimeter is primary for pitch — even though your hands are responding to the attitude indicator.

Two numbers, both rules of thumb from the IFH:

• Size the correction. For errors of less than 100 feet, a half bar width pitch change on the attitude indicator; for errors in excess of 100 feet, an initial full bar width correction (IFH 7-4).
• Size the rate. Make an attitude change that produces a vertical speed approximately double the altitude error — off by 100 feet, return at about 200 fpm. Larger errors get proportionally more, but never more than the optimum rate of climb or descent for the airplane. A deviation of more than 200 fpm from the desired rate of return is overcontrolling — trying to fix 200 feet at more than 400 fpm is the classic case (IFH 7-5).

Give them both numbers in the brief. "Small and smooth" is not a standard; 200 fpm is.

• Fixation — staring at a single instrument. The IFH example is a pilot who stares at an altimeter reading 200 feet low, wondering how the needle got there, while unconsciously exerting control pressure that starts an unnoticed heading change (IFH 6-12). Call it: "You're parked on the altimeter — go around the AI."
• Omission — dropping an instrument from the scan, usually after an attitude change. The most commonly omitted instrument is the slip/skid indicator (IFH 6-28). Call it: "Where's the ball?"
• Emphasis — relying on the one instrument you understand best instead of the combination. A pilot can hold reasonably close altitude with the attitude indicator alone but cannot hold it with precision without the altimeter in the scan (IFH 6-13).

Diagnose out loud, name the error, then give the single corrective action. Naming is the instruction; "you're wandering" is not.

The IFH describes three (IFH 6-11–6-12):

• Radial (hub and spoke) — eyes return to the attitude indicator between each flight instrument. The default for a beginner, because the AI is the only instrument showing pitch and bank at once.
• Inverted-V — AI to turn coordinator, back to AI, down to VSI, back to AI.
• Rectangular — across the top three (ASI, AI, altimeter) and back across the bottom three.

A scan that is too fast is a real error: a beginner "might cross-check rapidly, looking at the instruments without knowing exactly what to look for" (IFH 6-12). The fix is interpretation, not speed — slow them down and make them say aloud what each instrument is telling them. Also teach selective scanning: after establishing a standard rate turn for a 90° heading change, the heading indicator does not need rechecking for roughly 20–25 seconds (IFH 6-12, 7-25).

An out-of-trim airplane demands held control pressure, and held pressure destroys the light touch small corrections require while eating the attention that belongs to the scan. Trim is applied to relieve pressures already held to stabilize an attitude — never as a substitute for the wheel and rudder (IFH 7-13).

The IFH trim faults, with your correction:

• Improper seat or rudder pedal position — tension in the ankles makes it impossible to relax rudder pressure. Fix it on the ground.
• Confusion about the operation of trim devices, which differ among airplane types — some trim wheels are aligned with the airplane's axes, others are not, and some rotate contrary to expectation. Brief the direction on the ground every time a student moves to a new type; a student trimming the wrong way in cloud makes the problem worse at the speed of the wheel.
• Faulty sequence — trimming into the attitude instead of out of the pressure. "Hold the wheel first, then trim the pressure away."
• Excessive trim control — use trim continuously, but in small amounts.
• Failure to understand the principles of trim — including that the airplane is being trimmed for airspeed, not a pitch attitude (IFH 7-13).

The explanation phase happens on the ground, before the airplane (AIH 9-5). Cover:

• Objective — control the airplane by reference to instruments alone; this is a survival skill, not an instrument rating.
• The honest limitation — say out loud that this training does not prepare them for marginal weather or IMC. The AIH requires you to impress this on the learner, because attempting VFR flight into IMC is one of the most common causes of fatalities in NTSB data (AIH 9-11).
• Elements — the three skills, the control-and-performance method, the scan pattern.
• Completion standards — the numbers they will be held to: ±100 feet, ±10°, ±10 knots (AI.XI.A.S2).
• Safety — hood on and off procedure, who is looking for traffic (you are — 91.109(c)), altitude floor, and the positive three-way exchange of controls: "You have the flight controls" / "I have the flight controls" / "You have the flight controls" (AIH 9-8).

Demonstrate the way you want it imitated, in the order you explained it, and avoid extraneous activity so the picture stays clean; if the demonstration deviates from the explanation, acknowledge and explain the deviation immediately (AIH 9-5, 9-6).

1. "Cruise power set — I'm not touching it again."
2. "Attitude indicator: wings level, miniature airplane on the horizon. That's the control instrument."
3. "Now the result. Altimeter — steady. Heading indicator — steady. Airspeed — steady. Ball centered."
4. "Watch my eyes: AI, altimeter, AI, heading, AI, airspeed, AI. Never two performance instruments in a row."
5. "Altimeter's creeping up 40 feet. Less than a hundred, so half a bar width down, aiming for about 200 down. Watch it stop."
6. "Pressure's off — trimming it away. Now I'm free to scan again."

The narration teaches the reasoning, which is what transfers. A silent demonstration teaches only that the instructor can fly.

• Acceleration and deceleration — depending on how fast the erection system works, there may be a slight nose-up indication during rapid acceleration and a nose-down indication during rapid deceleration (IFH 5-19). Your student will see it on a level-off from a climb when they add cruise power.
• Small pitch and bank error after a 180° turn — these inherent errors are small and correct themselves within a minute or so of returning to straight-and-level flight (IFH 5-19).
• Erection time — the gyro is not erect at start-up; self-erection can take as long as 5 minutes but is normally complete in 2 to 3 minutes (IFH 5-19). This is a preflight teaching point, not a trivia question.
• Tumble limits — older instruments were limited to roughly 60° in pitch and 100° in roll and had caging mechanisms; newer instruments have no such restrictive tumble limits and no cage (IFH 5-19). This matters directly in Task XI.E: do not depend on a spillable attitude indicator after an upset, because its limits may have been exceeded (IFH 7-27).

• Heading indicator — a non-slaved gyro is not north seeking and must be set to the magnetic compass. Check it against the compass about every 15 minutes (IFH 5-20). Precession is the reason a student's "steady heading" quietly becomes a 20° error.
• VSI — the pointer lags a few seconds behind the actual pressure change, but it is more sensitive than the altimeter and is valuable as a trend instrument (IFH 5-8). Teach trend first, rate second — chasing the VSI needle is the single most common pitch error (IFH 7-12).
• Magnetic compass — reliable only in straight, level, unaccelerated flight. Northerly turning error leads, southerly lags; a rule of thumb is to roll out 15° plus half the latitude early on a northerly turn and the same amount late on a southerly one (IFH 5-13–5-14). Acceleration on easterly and westerly headings indicates a turn toward north, deceleration toward south — ANDS (IFH 5-14).

Set the guard rails in the brief, then enforce them without debate:

• Traffic — you are the safety pilot (91.109(c)). The student cannot see; collision avoidance is entirely yours (AI.XI.A.R3). If your own scan gets pulled inside to referee their altitude, you have quietly become a single pilot flying IFR in VMC with a passenger on the controls.
• Airspeed and bank trend — a nose-low, banked, accelerating combination is the entry to a spiral. Name it once; if it does not stop, take the airplane. Recovery from an upset the student created is Task XI.E, not a surprise.
• Fatigue and stress (AI.XI.A.R1) — hood work is exhausting. Twenty focused minutes beats an hour of degrading performance, and a fatigued student learns errors instead of skills.
• Disorientation — if the student reports the leans or vertigo, take the controls, get the hood off, and debrief it. Illusions are normal perceptions, not weakness, and the counter is trained reliance on the instruments (IFH 3-9).

This is its own risk element in all four of Tasks A–D, and applicants skip it because it feels like an ADM question rather than an instrument question. Teach it as a trigger, not a judgment call:

• The rule you give the student — advise ATC of the problem and, if necessary, declare an emergency before the situation deteriorates beyond the pilot's ability to recover (IFH 11-7). The decision point is while you still have capacity, which is always earlier than it feels.
• Name the triggers out loud in the brief — inadvertent IMC, a vacuum or electrical failure, disorientation that will not clear, or the honest realization that the airplane is ahead of them. Any one of those is a reason to key the mic, not a reason to try harder alone.
• Teach that declaring is the correct reaction, not an admission of failure. Once an emergency is declared ATC gives priority handling, and 91.3 lets the PIC deviate from any rule to the extent required (AIH 1-20). Say this explicitly or students will treat the emergency declaration as a paperwork threat.
• Build the habit in training — have the student actually use ATC for flight following and traffic advisories on hood flights, so asking a controller for help is a rehearsed action rather than a first attempt under stress (AIH 1-25).

The instructor angle: a student who has never said "N12345 requests" in calm air will not say it in cloud.

It changes when: integrated instruction says instrument references begin the first time each new maneuver is introduced, not in a dedicated hood block later (AIH 9-10). The AFH calls it the integrated or composite method — outside references and flight instruments used together, with roughly 90 percent of attention outside on visual references and traffic (AFH 3-5).

The payoff you can quote in a brief: learners trained this way develop the habit of continuously monitoring their own and the airplane's performance, which shows up as more precise airspeed control and therefore improved landings, better cross-country navigation, and a firm foundation for a later instrument rating (AIH 9-10).

The trap: integrated instruction is not hood training, and hood training is not IMC preparation. Say both boundaries out loud.
