1. How does runway or taxiway construction affect a flight?

It would affect the flight by changing the runway or taxiway or you may have to taxi around the intersictions.

2. What are some hazards of a flight being dispatched to an airport with freezing rain in the forecast?

Roughens large surface areas.

Distorts airfoil shapes.

Makes flight extremely dangerous or impossible in a few minutes.

May develop aloft.

3. How can a dispatcher mitigate the hazards in Question 2?

Dispatcher could direct the flight somewhere else or may plan for an extra fuel to prevent any damages from the freezing rains.

4. What factors should be considered when choosing a cruise altitude?

- federal aviation regulation - time to climb or total trip time - wind aloft forcast

- clouds - terrain - true airspeed - fuel consumption -

physiological factors - aircraft limitation - turbulence

5. According to Ops Spec C055, what is the name of method that we use to determine if an alternate is acceptable to use for a given flight?

“Alternate airport IFR weather minimum”

6. Once the aircraft is on the way to the alternate, what minimums are used?

use the approach chart minimums.

7. You are looking at using an airport with one runway as an alternate for a domestic flight. Runway 9 has an ILS and runway 27 has a LOC/BC approach. Can these two approaches be used for the two NAVAID rule? Why or why not?

No,

Because they have the same frequencies.

8. You are looking at using an airport with one runway as an alternate for a domestic flight. Runway 9 has an ILS and runway 27 has a VOR approach. Can these two approaches be used for the two NAVAID rule? Why or why not?

Yes,

Because we have two different frequencies

9. What is included in Basic Operating Weight?

32,463.64

10. What is included in Payload?

Aircraft, cargo, flight crew, crew baggage, payload or other equipment except the unusable fuel.

11. What is the standard weight of a passenger in this class?

195 lb

12. How do you know your weight and balance plotter is aligned correctly?

To line it up with the equal sign in the middle of the plotter horizontally.

Use the following information to complete the attached weight and balance graph and answer questions 13 – 16 regarding the fully loaded aircraft.

BOW: Use the one for our aircraft

ROW 5-8: 14 PAX

ROW 1-4: 14 PAX

Cargo: 1,000 LBS.

Fuel: 6700 LBS

Center Fuel: 2,000 LBS.

13. What is the final CG?

12.5

14. What is the total weight?

50000

15. What is the trim setting?

7.5

16. Is this aircraft overweight?

no

17. Are we within CG limits?

yes

Use the en route performance tables to answer questions 18 and 19.
