• This comprehensive study guide contains 200 verified practice questions covering
all major topics tested on the FAA Aircraft Dispatcher certification exam, with
detailed rationales for each correct answer to reinforce learning and understanding
of dispatcher responsibilities.

• Study this material by working through questions systematically, reviewing
rationales carefully to understand the regulatory framework, operational
procedures, and decision-making principles required for safe and efficient aircraft
dispatch operations.




Question 1: When conducting a pre-dispatch briefing, which document is the
dispatcher MOST critical to review first?

A) The aircraft maintenance log

B) The flight plan filed by the pilot

C) The weather briefing for the departure and arrival airports

D) The crew duty time records

E) The passenger manifest

✓ CORRECT ANSWER: C

RATIONALE: While all documents are important, the weather briefing must be
reviewed first as it directly impacts the feasibility of the flight and all subsequent
dispatch decisions. Adverse weather may necessitate route changes, alternate

,airport selections, or delays before filing a flight plan. The weather environment is
the primary factor affecting safety and must be evaluated before committing
aircraft and crew to a flight.



Question 2: Under Part 135, what is the maximum duty time for a flight crew
member in a 24-hour period without a required rest period?

A) 10 hours

B) 12 hours

C) 14 hours

D) 16 hours

E) 18 hours

✓ CORRECT ANSWER: C

RATIONALE: Federal Aviation Regulation Part 135.63 specifies that no certificate
holder may assign any flight crew member to duty for more than 14 hours in a 24-
hour period, unless an intervening rest period of at least 10 consecutive hours is
provided. This regulation is designed to prevent crew fatigue and maintain safety
standards.



Question 3: A dispatcher receives a weather report indicating moderate
turbulence at the planned cruise altitude. What is the dispatcher's primary
responsibility in this situation?

A) Immediately cancel the flight

B) File an alternate flight plan at a lower altitude

C) Notify the pilot of the turbulence report and ensure crew is aware for
operational planning

D) Request the FAA to close the airspace

E) Change the arrival airport

,✓ CORRECT ANSWER: C

RATIONALE: The dispatcher must ensure that all relevant weather information,
including turbulence reports, is communicated to the pilot. While the flight need
not be canceled, the crew must have complete information to make informed
decisions about cruise altitude, routing, and passenger comfort. The pilot and
dispatcher share responsibility for safe flight operations.



Question 4: Which regulation governs the minimum equipment list (MEL) for
commercial aircraft operations?

A) Part 91

B) Part 121

C) Part 135

D) Part 61

E) Part 101

✓ CORRECT ANSWER: B

RATIONALE: The Minimum Equipment List (MEL) is governed under Part 121 for
large commercial operations. The MEL specifies which aircraft equipment may be
inoperative and still allow the aircraft to depart safely. Part 135 operators follow
similar procedures. Parts 91, 61, and 101 do not address MEL requirements for
commercial operations.



Question 5: An aircraft dispatched for a cargo flight has a weight and balance
concern. The center of gravity (CG) is calculated to be 0.5% aft of the
maximum limit. What should the dispatcher recommend?

A) Approve the flight as 0.5% is within acceptable tolerance

B) Redistribute cargo to bring CG within limits before departure

C) Request the pilot to file a modified flight plan

, D) Proceed with the flight and monitor weight continuously

E) Cancel the flight immediately

✓ CORRECT ANSWER: B

RATIONALE: The center of gravity must be within published limits for all phases of
flight. An out-of-limit CG condition compromises aircraft stability and control. The
dispatcher must ensure load and balance calculations are within aircraft
specifications before release. Cargo must be redistributed to bring the CG within
the envelope, or cargo must be offloaded.



Question 6: What is the dispatcher's responsibility regarding the aircraft's
airworthiness certificate?

A) The dispatcher must hold an airworthiness certificate

B) The dispatcher must ensure the aircraft has a valid airworthiness certificate on
file before dispatch

C) The dispatcher need only verify the certificate if specifically requested

D) The airworthiness certificate is only required for international flights

E) The pilot is solely responsible for certificate verification

✓ CORRECT ANSWER: B

RATIONALE: Under 14 CFR Part 135, the dispatcher must verify that the aircraft has
a current, valid Airworthiness Certificate before releasing it for flight. This is a
fundamental requirement ensuring the aircraft meets all FAA airworthiness
standards. The dispatcher shares responsibility with the pilot for this verification.



Question 7: During dispatch, a crew calls to report that the departure airport
is now below operational minimums due to sudden weather deterioration.
What is the dispatcher's immediate action?

A) Issue a go/no-go decision within 5 minutes
