9.7.5.2 Telephone users. When using the telephone to make a reservation, you are prompted for input of information about what you wish to do. All input is accomplished using the keypad on the telephone. The only problem with a telephone is that most keys have a letter and number associated with them. When the system asks for a date or time, it is expecting an input of numbers. A problem arises when entering an aircraft call sign or tail number. The system does not detect if you are entering a letter (alpha character) or a number. Therefore, when entering an aircraft call sign or tail number two keys are used to represent each letter or number. When entering a number, precede the number you wish by the number 0 (zero) i.e., 01, 02, 03, 04, . . .. If you wish to enter a letter, first press the key on which the letter appears and then press 1, 2, or 3, depending upon whether the letter you desire is the first, second, or third letter on that key. For example to enter the letter “N” first press the “6” key because “N” is on that key, then press the “2” key because the letter “N” is the second letter on the “6” key. Since there are no keys for the letters “Q” and “Z” e.CVRS pretends they are on the number “1” key. Therefore, to enter the letter “Q”, press 11, and to enter the letter “Z” press 12.
NOTE.
Users are reminded to enter the “N” character with their tail numbers. (See TBL GEN 3.3.4 and TBL GEN 3.3.5 Helpful Key Entries).

Helpful Key Entries
# After entering a call sign/tail number, depressing the ‘‘pound key” (#) twice will indicate the end of the entry.
*2 Will take the user back to the start of the process.
*3 Will repeat the call sign/tail number used in a previous reservation.
*5 Will repeat the previous question.
*8 Tutorial Mode: In the tutorial mode each prompt for input includes a more detailed description of what is expected as input. *8 is a toggle on/off switch. If you are in tutorial mode and enter *8, you will return to the normal mode.

9.8 Operations at Uncontrolled Airports with Automated Surface Observing System (ASOS)/Automated Weather Sensor Sys-tem(AWSS)/Automated Weather Observation System (AWOS)
9.8.1 Many airports throughout the National Air-space System are equipped with either ASOS, AWSS, or AWOS. At most airports with an operating control tower or human observer, the weather will be available to you in a METAR hourly or special observation format on the Automatic Terminal Information Service (ATIS) or directly transmitted from the controller/observer.
9.8.2 At uncontrolled airports that are equipped with ASOS/AWSS/AWOS with ground.to.air broadcast capability, the one.minute updated airport weather should be available to you within approximately 25 NM of the airport below 10,000 feet. The frequency for the weather broadcast will be published on sectional charts and in the Airport/Facility Directory. Some part.time towered airports may also broadcast the automated weather on their ATIS frequency during the hours that the tower is closed.
9.8.3 Controllers issue SVFR or IFR clearances based on pilot request, known traffic and reported weather; i.e., METAR/SPECI observations, when they are available. Pilots have access to more current weather at uncontrolled ASOS/AWSS/AWOS air-ports than do the controllers who may be located several miles away. Controllers will rely on the pilot to determine the current airport weather from the ASOS/AWSS/AWOS. All aircraft arriving or depart-ing an ASOS/AWSS/AWOS equipped uncontrolled airport should monitor the airport weather frequency to ascertain the status of the airspace. Pilots in Class E airspace must be alert for changing weather conditions which may effect the status of the airspace from IFR/VFR. If ATC service is required for IFR/SVFR approach/departure or requested for VFR service, the pilot should advise the controller that he/she has received the one.minute weather and state his/her intentions.
