AIRCRAFT DISPATCHER FINAL PAPER
PRACTICE SOLUTION TESTED QUESTIONS
WITH COMPLETE ANSWERS
●● What part of the FARs discusses the certification of dispatchers?
Answer: Part 65.
●● What causes the weather?
Answer: The sun.
●● What 3 things are required for radiation fog to form?
Answer: Clear skies, little or no wind, small temperature dewpoint
spread of less than 5 degrees F.
●● Is low pressure an area of convergence or divergence?
Answer: Convergence; winds flow inward; counter-clockwise.
●● What type of clouds will you notice along a warm front?
Answer: Stratiform clouds with the possibility of embedded
thunderstorms.
●● What does the ceiling do as a warm front approaches?
,Answer: Gradually becomes lower.
●● Name a few characteristics of a warm front.
Answer: Stratus cloud; extensive geographical coverage; slow-moving;
rime ice; continuous precipitation.
●● What are the stages of a thunderstorm?
Answer: Cumulus, mature, dissipating.
●● What approach category is the B737?
Answer: Category C (121-140 kt).
●● What is a dryline?
Answer: Moist warm air flowing north from the Gulf of Mexico abuts
drier, cooler, denser air; differences in moisture & temperatures spawn
squall lines and tornadoes.
●● What are squall lines?
Answer: Unstable, narrow, non-frontal band of convective activity
usually found in advance of a cold front.
●● How often are surface analysis charts issued?
Answer: Every 3 hours.
,●● How often are constant pressure charts issued?
Answer: Twice a day at 0000Z and 1200Z.
●● How often are TAFs issued?
Answer: 4 times a day starting at 0000Z.
●● How often are weather depiction charts issued?
Answer: Every 3 hours.
●● What does hatching represent on a constant pressure chart?
Answer: Winds of 70 - 110 kt.
●● Where are you likely to find CAT?
Answer: In an upper trough on the cold (polar) low pressure side of the
jet stream.
●● How far apart are isobars depicted on surface analysis charts?
Answer: 4 mb.
●● What weather providers are you authorized to obtain weather from?
Answer: NWS, WSI, FSS, and Jeppesen.
, ●● How can you detect a potential for windshear in weather reports and
forecasts?
Answer: Isobars close together on charts; reports of thunderstorms;
PIREPS, TAFS, SIGMETS, AIRMETS.
●● What does the pneumatic system do?
Answer: Uses compressed bleed air from engines for various systems
including engine start, cabin pressurization, and anti-ice protection.
●● Do we have anti-ice or deice on the B737?
Answer: Anti-ice; hot bleed air (stages 5 and 9).
●● If we use anti-ice, is there a performance penalty?
Answer: Yes, it is expressed in a subtraction of pounds of payload.
●● What is an MEL?
Answer: Minimum Equipment List - items authorized to be inoperative.
●● If maintenance advises that DME must be deferred, can we still fly
above FL240?
Answer: Yes, because the MEL states we can dispatch with just one
DME.
