When flying HAWK N666CB, the proper phraseology for initial contact with McAlester Flight Service is: McAlester Flight Service Station, Hawk Six Six Six Six Charlie Bravo, Receiving Ardmore Vortac, Over.’, McAlester Station, Hawk Six Six Six Cee Bee, Receiving Ardmore Vortac, Over.’, McAlester Radio, Hawk November Six Six Six Charlie Bravo, Receiving Ardmore Vortac, Over.’

Back

McAlester Radio, Hawk November Six Six Six Charlie Bravo, Receiving Ardmore Vortac, Over.’

Answer explanation

Remember that there are different types of facilities, and that each facility will be addressed a little differently over the radio. In this case, Flight Service is always referred to as Radio, so that’s why the correct answer choice needs to start with McAlester Radio. Another giveaway here is that the N in the N-number of N666CB will be pronounced November.

If Dallas Executive (RBD) tower is not in operation, which frequency should be used as a Common Traffic Advisory Frequency (CTAF) to monitor airport traffic?

Back

127.25 MHz.

Answer explanation

After locating the Dallas Executive (RBD) airport icon on the chart, look for the airport information text next to the icon. Remember that in the testing supplement legend, you’re actually being told exactly where a lot of information is on the Sectional Chart. In this case, if we want to find the CTAF frequency, we can consult the legend: (See beginning of Test Supplement Book)

The CTAF frequency is always going to be to the left of the circle C icon. In the legend section above, the CTAF frequency is also the CT or Control Tower frequency, and it is 118.3.
