Mixed Deck — All DADE Topics Flashcards

Standard passenger weights used in Part 121 load planning are primarily intended to:

Answer: Simplify load planning using FAA-approved statistical averages instead of weighing each individual

FAA-approved standard weights use statistical averages for passengers and baggage, allowing efficient load planning without individually weighing each traveler.

When must a Part 121 carrier notify the FAA of an aircraft accident?

Answer: Immediately by the most expeditious means available

Aircraft accidents must be reported immediately to the NTSB by the most expeditious means available under 49 CFR Part 830.

A dispatcher notices ATIS information 'Kilo' is current. What does this indicate?

Answer: The current ATIS identifier is the 11th sequential letter of the alphabet

ATIS identifiers cycle through the phonetic alphabet; 'Kilo' is the 11th letter, indicating the 11th update.

What is the effect of high density altitude on aircraft performance?

Answer: Reduced performance and increased takeoff distances

High density altitude indicates that the air is less dense, similar to conditions found at higher altitudes or in hot weather. Less dense air reduces the efficiency of aircraft engines, resulting in less thrust, and diminishes the lift generated by the wings. Consequently, aircraft require longer takeoff distances, experience slower climb rates, and have reduced payload capacity.

When ATC issues an Expect Further Clearance (EFC) time during an airborne hold, the dispatcher's concern regarding fuel should focus on:

Answer: Verifying the aircraft has sufficient fuel to hold until EFC plus fly to the alternate and land with required reserves

The dispatcher must verify that available fuel covers the holding period to EFC, plus the missed approach, alternate trip, and required fuel reserves.

When computing takeoff weight for dispatch purposes, what does zero fuel weight (ZFW) represent?

Answer: The aircraft weight with all payload but excluding usable fuel

Zero fuel weight is the total weight of the aircraft with all payload (passengers, cargo, crew) but excluding usable fuel.

What is the primary concern when an aircraft's CG approaches the forward limit?

Answer: Reduced elevator effectiveness and higher control forces required for rotation

Near the forward CG limit, the elevator must work harder to raise the nose, requiring greater control forces at rotation and potentially increasing stall speed.

What does a freezing level at 5,000 feet MSL mean for dispatch of an aircraft without de-icing equipment?

Answer: Potential structural icing risk exists below 5,000 feet in visible moisture

With a freezing level at 5,000 feet, any flight through visible moisture below that altitude risks structural icing on an aircraft without de-icing equipment.

A Temporary Flight Restriction (TFR) is established by NOTAM under which FAR authority?

Answer: 14 CFR Part 91.137

14 CFR 91.137 authorizes TFRs for disaster/hazard areas, and related sections cover Presidential, VIP, and security TFRs.

Which statement about VDL Mode 2 (VHF Digital Link Mode 2) is correct?

Answer: It is a digital data link standard that replaces analog ACARS on VHF frequencies for higher data rates

VDL Mode 2 is a higher-speed digital data link operating in the VHF band that is replacing older analog ACARS for AOC and ATC datalink communications.

What is the primary purpose of a Load and Trim Sheet?

Answer: To document the aircraft's total weight and CG position and confirm both are within certified limits

The Load and Trim Sheet documents computed weight and CG, confirming both are within limits before the captain and dispatcher sign the dispatch release.

How many hours of dispatch experience or training are required before an applicant can take the Aircraft Dispatcher practical test?

Answer: 200 hours of approved training under an approved program or 2,000 hours of flight time

Applicants must complete either 200 hours of approved dispatch training under an FAA-approved program or accumulate 2,000 hours of relevant flight time experience.

What communication action must a dispatcher take when a crew reports an in-flight emergency via ACARS?

Answer: Immediately assess the situation, provide all possible assistance, notify company operations, and coordinate with ATC as needed

In an emergency, the dispatcher must actively assist the crew, coordinate with ATC and company resources, and provide any information that aids safe resolution.

What does 'ADS-B' stand for in aircraft communication systems?

Answer: Automatic Dependent Surveillance–Broadcast

ADS-B stands for Automatic Dependent Surveillance–Broadcast. It is a surveillance technology where an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked by ground stations and other aircraft. This system enhances air traffic control's ability to monitor aircraft and improves situational awareness for pilots by providing real-time position data.

What must a dispatcher do when a SIGMET is issued for severe turbulence along a released flight's route?

Answer: Evaluate the information and advise the pilot-in-command so appropriate action can be coordinated

Upon receiving a SIGMET, the dispatcher must evaluate the impact on the flight and immediately advise the PIC so they can jointly determine the appropriate response.

What is 'VMCA' and how does it affect dispatch decisions?

Answer: Minimum control speed in the air with critical engine inoperative; must remain below V2 speed

VMCA is the minimum control speed in the air with the critical engine inoperative, and V2 must be equal to or greater than 1.1 × VMCA to ensure controllability after engine failure during takeoff.

What is the purpose of the 8.33 kHz channel spacing now required in European airspace?

Answer: To triple the number of available VHF communication channels in congested airspace

8.33 kHz channel spacing replaces 25 kHz spacing, tripling available VHF frequencies to reduce congestion in high-density European airspace.

How does temperature inversion affect low-level turbulence and visibility for dispatch?

Answer: Inversions trap pollutants and moisture below, reducing visibility, while the top of the inversion can produce wind shear turbulence

Temperature inversions trap pollutants and moisture, reducing surface visibility, and the shear zone at the inversion top can produce significant turbulence.

Which federal regulation specifically addresses the requirement for two-way radio communication capability for airplanes operated under Part 121?

Answer: FAR 121.347

FAR 121.347 prescribes the radio communication equipment requirements for air carrier operations under Part 121.

What is the function of hazard identification in SMS?

Answer: To identify potential safety risks and hazards

Hazard identification is the process of identifying potential risks and safety issues that could affect aviation operations, enabling appropriate mitigation measures.
