Read back the clearance and review the DP. Although a
departure frequency was not given in the clearance, note that
on the DP, the departure control frequency is listed as 123.8
for the southern sector. Since a departure from runway 24
is anticipated, note the instruction to climb to 2,100 prior
to turning. After tuning in the appropriate frequencies and
setting up navigation equipment for the departure routing,
contact ground control (noting that this is IFR) and receive
the following clearance:

"Cessna 1230A taxi to runway 24 via taxiway

Read back the clearance and aircraft call sign. After a review
of the taxi instructions on the airport diagram, begin to taxi
and check the flight instruments for proper indications.

Hold short of runway 24 and complete the before takeoff
checklist and engine run-up. Advise the tower when ready
for takeoff. The tower gives the following clearance:

"Cessna 30A cleared for takeoff runway 24.
Caution wake turbulence from 737 departing to the

Taxi into position. Note the time off on the navigation log,
verify that the heading indicator and magnetic compass are
in agreement, the transponder is in the ALT position, all the
necessary lights, equipment, and pitot heat are on. Start the
takeoff roll. To avoid the 737's wake turbulence, make note
of its liftoff point and take off prior to that point.

En Route
After departure, climb straight ahead to 2,100 feet as directed
by the Birmingham Three Departure. While continuing a
climb to the assigned altitude of 4,000 feet, the following
instructions are received from the tower:

"Cessna 30A contact Departure"

Acknowledge the clearance and contact departure on the
frequency designated by the DP State the present altitude
so the departure controller can check the encoded altitude
against indicated altitude:

"Birmingham Departure Cessna 1230A climbing
through 2,700 heading 240."

Departure replies:

"Cessna 30A proceed direct to Brookwood and resume
own navigation. Contact Atlanta Center on 134.05."

Acknowledge the clearance, contact Atlanta Center and
proceed direct to Brookwood VORTAC, using the IFR-
approved UPS equipment. En mute to Kewanee, VORTAC
Atlanta Center issues the following instructions:

"Cessna l230A contact Memphis Center on

Acknowledge the instructions and contact Memphis Center
with aircraft ID and present altitude. Memphis Center
acknowledges contact:

"Cessna 1230A, Meridian altimeter is 29.87. Traffic
at your 2 o'clock and 6 miles is a King Air at 5,000
climbing to 12,000."

Even when on an IFR flight plan, pilots are still responsible
for seeing and avoiding other aircraft. acknowledge the call
from Memphis Center and inform them of negative contact
with traffic due to IMC.

"Roger, altimeter setting 29.87. Cessna 1230A is in
IMC negative contact with traffic."

Continue the flight, and at each fix note the arrival time on
the navigation log to monitor progress.

To get an update of the weather at the destination and issue
a pilot report, contact the FSS servicing the area. To find
the nearest AFSS, locate a nearby VOR and check above
the VOR information box for a frequency. In this case, the
nearest VOR is Kewanee VORTAC, which lists a receive-
only frequency of 122.1 for Greenwood FSS. Request a
frequency change from Memphis and then attempt to contact
Greenwood on 122.1 while listening over the Kewanee
VORTAC frequency of 113.8:

"Greenwood Radio Cessna 1230A receiving on
frequency 113.8, over."

"Cessna 30A, this is Greenwood, go ahead."

"Greenwood Radio, Cessna 30A is currently 30 miles
south of the Kewanee VORTAC at 4,000 feet en
route to Gulfport. Requesting an update of en route
conditions and current weather at GPT, as well as

"Cessna 30A, Greenwood Radio, current weather at
Gulfport is 400 overcast with 3 miles visibility in light
rain. The winds are from 140 at 7 and the altimeter
is 29.86. Weather across your route is generally IFR
in light rain with ceilings ranging from 300 to 1000
overcast with visibilities between 1 and 3 miles.
Pensacola weather is much better with ceilings now
at 2,500 and visibility 6 miles. Checking current
NOTAM at GPT shows the Localizer out of service
and runway 18/36 closed."
