PALS has been assigned a unique ICAO call sign to be used for PALS missions, PALS HOPE.
The 3 letter designator (3LD) for air/ground communications will be PLZ followed by a unique number assigned by PALS based on your PALS Member ID. You can find your number in the Pilot Community or day-of flight email which includes your itinerary.
The call sign and instructions for use of the call sign were issued by the FAA.
To use the new call sign:
File your flight plan with your PALS call sign PLZ426 (for example), and put PALS HOPE and your usual tail number, for example, N345GW in the Remarks.
Change the transponder ADS-B Flight ID to PLZ426
– File a flight plan with whatever software you are currently using.
– For instructions on how to change the ADS-B Flight ID consult the following:
Q. Can we drop the HOPE from PALS HOPE?
A. FAA rules state it should not be a one-syllable word, typically 2 to 3 syllables is best
Q. Why can’t it be PALS FLIGHT?
A. FAA rules prohibit the word FLIGHT
Q. How did PALS choose the PLZ and PALS HOPE?
A. There are over 5,000 3LD Designators already in use. We needed to choose one that was not in use.
Q. The ATC called it PALS or PALS FLIGHT, can I call it PALS or PALS FLIGHT?
A. For the first call out, you should use PALS HOPE. If Controller truncates, you can repeat back what they said. This is new for the controllers, they may not have updated telephony codes. It will not cause issues if they call you PALS, and they will get used to the PALS HOPE.
Q. I forgot to listen for PALS HOPE – I need to get used to it.
A. It may take time for you to grow accustomed to listening for the new call sign. If you do not respond, the controller may say “Papa Lima Zulu” to get your attention. The more you use it, it will grow on you. You may want to keep a Post-it on the dashboard while you are starting to use it.
Q. How are the air traffic controllers made aware of the new call signs?
A. Air traffic controllers mostly become aware of new call signs through usage. New call signs are added all the time. Call signs are kept in a book and digital information system.
Q. Can we change our call sign number? Can we use fewer digits than what is assigned?
A. No. These numbers were assigned based on PALS member ID. We have to be able to provide frequent updates to FAA of the call sign numbers, and this system is the simplest way to ensure recordkeeping and compliance.
Q. What if the plane is rented?
A. You can reach out to the place you rent the plane from and ask them to add the function on the transponder to change the call sign. At least one pilot has had success with this.
Q. What if I change the call sign in the flight plan, but not in the transponder?
A. They must be the same. This is a very important requirement. You should not change the call sign in the flight plan without changing the transponder – you will not be ADSB compliant.
Q. Do I have to use my PALS call sign? What is the benefit to using it?
A. You do not need to use it if you do not want to. Some pilots report getting more direct routing based on using the call sign, which can be helpful if the passenger is uncomfortable. This is a courtesy. The call sign does not give you emergency routing. If you are unable to change your transponder, please do not use it in the flight plan.
Q. How to file flight plan with the new call sign?
A. There are a few ways.
Here are the FAA Rules for Choosing a Call Sign that PALS had to follow:
Among other rules, telephony is further vetted by ICAO and FAA to confirm it:
