1)Would you expect RWY 22 to be equipped with a clearway?
Yes. Compare the takeoff run available (TORA) of 6,402 feet to the takeoff distance available (TODA) of 7,388 feet, and you can see that we have slightly less than 1,000 feet of clearway.

2)Are any of the runways equipped with a runway visual range (RVR) transmissometer?
Negative. 

3)You are planning to depart RWY 04. FSS is reporting 3/8 SM but you can count 13 sets of runway lights in the touch down zone (TDZ). Are you legal to depart? Answer for both fixed-wing and rotorcraft.
Fixed-wing: Negative, accredited visibility is too low.
Rotorcraft: Affirmative, rotorcraft takeoff minima is ¼ SM and we exceed that.

4)What must the pilot in command do to confirm obstacle clearance when departing RWY 04?
 Cross the departure end of the runway by at least 35 feet, make good a minimum climb gradient of 200 FT/NM, no turns below 400 feet above aerodrome elevation (AAE). 

5)What is the precise magnetic track of RWY 22?
217 degrees. 

6)Your planned climb speed on a SPEC VIS Departure off RWY 22 is 125 KIAS. What minimum ceiling and visibility will allow this departure given the above information?
With this IAS, you are a Category C aircraft and thus require a minimum visibility of two SM and a minimum ceiling of 1,200 feet. You must climb VMC to 2,400 feet ASL and the aerodrome elevation is just over 1,200 feet. The net difference requires a visual climb for 1,200 feet. 

7)You would expect the ATIS to operate (limited hours/24-7), please choose.
24-7, no limited hours symbol.
