FAA Airline Transport Pilot Multiengine Airplane Knowledge Test Practice Test

The FAA Airline Transport Pilot Multiengine Airplane Knowledge Test (ATM) covers aviation knowledge applied to multiengine airplane operations. Practice questions sample aircraft systems, flight instruments, navigation, weather-related flight planning, performance calculations, and operational checks such as confirming landing-gear position before landing.

About the FAA Airline Transport Pilot Multiengine Airplane Knowledge Test Exam

Preparing for this test involves interpreting indications and applying aviation concepts to flight decisions. Aircraft-systems questions may ask how a propeller governor, magneto, anti-skid system, or fuel-pressure indication relates to operation or a possible abnormal condition. Instrument and navigation questions can involve setting an altimeter to local pressure or interpreting a centered VOR course deviation indicator. Flight-planning problems connect wind to groundspeed and en route time, while performance calculations require understanding quantities such as weight-and-balance moments. Operational scenarios also test whether a pilot can relate thrust, drag, and flight condition, and recognize the importance of verifying that the landing gear is down and locked. These topics support the practical work of monitoring aircraft status, assessing flight information, and making sound decisions during multiengine operations.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

In an airplane equipped with a constant-speed propeller, what does the propeller governor primarily do?

  1. AMaintains selected engine manifold pressure by changing throttle position
  2. BChanges blade angle to maintain the selected propeller RPM
  3. CPrevents the engine from exceeding its maximum cylinder-head temperature
  4. DSynchronizes the two engines' ignition timing
Show answerCorrect answer: B

A constant-speed governor senses RPM and adjusts propeller blade angle to keep RPM near the selected value as power or flight conditions change. It does not directly control manifold pressure or engine temperature.

Question 2

A pilot is planning a flight with a forecast headwind. Compared with a no-wind estimate, what is the expected effect on groundspeed and en route time, all else equal?

  1. AGroundspeed increases and en route time decreases.
  2. BGroundspeed decreases and en route time increases.
  3. CGroundspeed and en route time are unchanged.
  4. DGroundspeed decreases but en route time also decreases.
Show answerCorrect answer: B

A headwind reduces groundspeed relative to true airspeed. For a fixed route distance, lower groundspeed generally means a longer en route time.

Question 3

When setting a barometric altimeter for a local altimeter setting, what does the pilot primarily accomplish?

  1. AAdjusts the instrument’s pressure reference so it indicates altitude relative to the local pressure datum
  2. BCorrects the altimeter for aircraft weight
  3. CSets the indicated airspeed scale to true airspeed
  4. DEliminates all errors caused by nonstandard temperature
Show answerCorrect answer: A

The barometric setting adjusts the pressure reference used by the altimeter, allowing its indication to correspond more closely to altitude relative to the local pressure datum. It does not remove temperature-related errors.

Question 4

What is the primary function of an airplane’s anti-skid system during braking?

  1. ATo prevent the wheels from rotating whenever brake pressure is applied.
  2. BTo modulate brake pressure to help prevent wheel skid and maintain effective braking.
  3. CTo increase tire pressure as runway friction decreases.
  4. DTo steer the airplane automatically toward the runway centerline.
Show answerCorrect answer: B

An anti-skid system senses an impending wheel skid and reduces or modulates brake pressure as needed. This helps preserve tire-runway traction and directional control while allowing effective braking.

Question 5

A pilot is using a VOR receiver to track a selected course. What does a centered course deviation indicator (CDI) indicate?

  1. AThe aircraft is on the selected course, but the indication alone does not show whether it is moving toward or away from the station.
  2. BThe aircraft is directly over the VOR station.
  3. CThe aircraft is on the selected course and tracking inbound, regardless of the TO/FROM indication.
  4. DThe selected course is aligned with the aircraft’s current heading.
Show answerCorrect answer: A

A centered CDI means the aircraft is on the selected course line, within the instrument’s sensitivity. It does not by itself establish station passage, direction of travel, or alignment with heading; the TO/FROM indication and aircraft motion provide additional information.

Question 6

A pilot notices that the fuel pressure indication is below its normal range. What is the most appropriate general response?

  1. AIgnore it if the engine is currently producing normal power.
  2. BConsult the aircraft checklist and promptly assess the fuel system and engine indications.
  3. CIncrease pitch attitude to restore fuel pressure.
  4. DSwitch off all electrical equipment before taking any other action.
Show answerCorrect answer: B

An abnormal fuel-pressure indication may signal a fuel-supply or system problem. The pilot should use the airplane-specific checklist, cross-check related indications, and take appropriate action rather than dismissing the warning.

Question 7

In a reciprocating engine, what is the principal function of the magneto?

  1. ATo meter fuel according to manifold pressure.
  2. BTo maintain oil pressure during engine operation.
  3. CTo generate high-voltage ignition for the spark plugs independently of the aircraft electrical system.
  4. DTo regulate alternator output voltage.
Show answerCorrect answer: C

A magneto is an engine-driven ignition source that generates the high voltage needed at the spark plugs. Because it operates independently of the aircraft battery and alternator, the engine can continue running if the aircraft electrical system fails, subject to the airplane’s design and condition.

How to use this practice test

The free practice session draws up to 20 random questions from a 50-question ATM bank. Answer the questions, then use the results shown after the session to identify concepts that need another review, such as instrument interpretation, aircraft systems, or flight-planning calculations.

Preparation tips

  • For constant-speed propellers, review how the governor changes blade angle to maintain the selected RPM, and distinguish that function from engine power control.
  • Practice converting wind effects into groundspeed and en route time, keeping true airspeed and route distance consistent in each calculation.
  • Work through altimeter-setting and VOR CDI scenarios, stating what each indication tells you and what it does not establish.
  • Review multiengine aircraft-system indications and abnormal cues, including low fuel pressure, magneto function, and anti-skid braking.
  • Practice weight-and-balance moment calculations and verify landing-gear position and locking indications as part of landing checks.
