Dispatcher Distance Learning Course-Week 12


This is View Only - You must be an enrolled student with AGS to take this exam!!!






1. Computerized aviation weather reports are provided on the Internet by:
GTE; DTC; and the Aircraft Dispatcher Federation (ADF) at www.dispatcher.org
United Airlines.
Automated Flight Service Stations (AFSS).


2. Load meters are also known as ammeters and their readings are calculated in amps.
True
False


3. Reduced thrust takeoffs are encouraged to:
save fuel.
achieve increased engine life and improve engine reliability.
reduce airport noise.


4. Electricity is a form of energy as a result of electrons and positive ions separating.
True
False


5. Buffet speeds and optimum cruise altitudes are dependent on:
gross weight.
temperature.
pressure altitude.


6. Cruising at 4000' above/below optimum cruise altitude results in a fuel penalty of 4-5%.
True
False


7. A VDP is used in conjunction with:
non-precision approaches.
precision approaches.
circling approaches.


8. Separating electrons and ions can be accomplished:
chemically.
by friction.
Both a and b.


9. Climb limit weight is based on engine bleed air ON for normal air conditioning.
True
False


10. Max runway slope for Part 121 operations is:
+-2%
+-4%
not limited under normal operating conditions.


11. An ILS has weather minimums of 200' and 1/2 mile. The captain has 48 hours PIC time in type. The required minimums for this approach are:
200' and 1/2 mile.
300' and 1 mile.
RVR 2400


12. As a swept back wing encounters turbulence and flexes up, it washes out at the wing tips which decrease the angle of attack and unloads the wing.
True
False


13. "Dutch roll" is:
a term coined from fat Dutch captains who sauntered through the old terminal at Schiphol.
a characteristic of sweptwing aircraft to yaw and roll at the same time.
a tendency for swept wing aircraft to yaw and pitch about the lateral axis.


14. Critical Mach is a free stream Mach number where local sonic flow occurs. Pick a true answer
The B737 and B727 top speed (Mach limit) is a transonic Mach number.
Mach speed is the ratio of IAS to the speed of sound (SOS).
The speed of sound is directly related to temperature and pressure.


15. The primary reason for operating jets at high altitudes is due to:
fuel efficiency; the higher the altitude, the lower the temperature, hence a better fuel burn.
weather avoidance at lower altitudes.
tailwinds associated with the jet stream.


16. On a hot day, V1 tends to be rather low because braking efficiency is not good and it takes a longer distance to get an airplane stopped than on a cool day.
True
False


17. Class I Navigation is based on operations conducted within the designated service volume of ICAO standard airway navigation facilities (VORs and NDBs).
True
False


18. A flight may depart an airport in VFR conditions but must obtain an IFR clearance within:
1 hour after departure.
50 miles after departing the airport.
the first 5000 feet of climb.


19. A full ILS requires an operative LOC, GS, and OM or FAF. What can be substituted for an OM?
A precision or surveillance radar fix.
An NDB, VOR, DME fix, or published minimums GSIA fix.
All of the above.


20. The landing minimums are RVR 1800. The PIC is on "high minimums". What are his minimums?
RVR 1800
RVR 4500
RVR 2400
