Listening to Gulfstream Aerospace G500 and G600 Testing

SavannahGulfstream Aerospace is well along in flight testing of their new G500 and G600 models. Both aircraft are being built at and tested out of Gulfstream’s factory in Savannah at the Savannah-Hilton Head International Airport. If you live near the Georgia coast, you can hear some of the testing activity of these aircraft if you know what to listen for and where to listen for them at. You can also track them on Mode-S/ADS-B while you listen to them. Using Mode-S to identify the flights is actually the best way to identify a Gulfstream test flight as a G500 or G600 instead of another aircraft undergoing flight testing.

What do you need to listen for? First, you need to listen out for the flight testing callsign: GULFTEST ##. They almost always use GULFTEST whether they’re testing a G500 of G600, a G550 or G650, or an older aircraft that’s been in for service. On Mode-S or in Flight Aware, the callsign will show as GLF##. After you’ve found the right GLF## flight, look for an aircraft type of GA5C, which is the G500 or GA6C, which is the G600. They almost always have ADS-B turned on, so you can track their flight path as they do their test flights. To date, I’ve tracked seven G500s and five G600s, here are their N-Numbers and Mode-S codes:

G500
N500GA (A63A87)
N502GS (A64205)
N503G (A645AB)
N504GS (A64973)
N505GD (A64D1D)
N507GD (A6548B)
N511GD (A665C0)

G600
N600G (A7C7D5)
N601GA (A7CB8D)
N720GD (A9A426)
N730GD (A9CBA5)
N740GD (A9F324)

Where do you listen for them at? Most of the test flights take place off of the Georgia coast, so the local air traffic control frequencies for Savannah and the coastal area including Brunswick-Golden Isles Airport as well as SEALORD primary frequencies for offshore SUAs are your best bet and are listed below. Sometimes, the test flights are over land or are cross-country flights, so Jax Center and Atlanta Center frequencies are your best bets then. The Jax Center and Atlanta Center frequencies that can easily be heard from the Savannah area are listed on my MilAir page. The test flights can also be heard on two Gulfstream frequencies which are listed below.

119.100 – Savannah IAP Tower
124.975 – Hunter AAF Tower
123.000 – Brunswick-Golden Isles Airport
120.400 – Savannah Approach/Departure
125.300 – Savannah Approach/Departure
124.675 – Jacksonville Center Jekyll Low
126.125 – Jacksonville Cener Statesboro High
126.750 – Jacksonville Center Brunswick Low
132.425 – Jacksonville Center Hunter High
132.925 – Jacksonville Center Allendale Low
120.950 – SEALORD North Primary
123.200 – WCM9, Gulfstream Aerospace
123.350 – GULFTEST Air-to-Air

The Gulfstream flight testing is something you can listen to with almost any inexpensive scanner (almost all of them these days have VHF airband coverage). Amateur radio operators can also listen to them with a lot of 2m/70cm radios since many rigs that have those bands also offer extended receive in the VHF airband range. Most of the testing also takes place over 10,000 ft, so it’s not hard to hear with handheld radios, especially if you use something like the Diamond RH77CA. Even though most of the aviation activity I listen to is military aviation, I still enjoy monitoring the Gulfstream testing and catching the new G500s and G600s as they start testing.
