Today, PT. Tiarangkasa answer request from IDAF to test smoke trail with a colour other than white. This test is performed to determine the propeller engine can be able to use multi-color smoke trail or not. During this test we use red and blue colour for smoke trail beside white. The conclusion of the test is further development still needed in order to decrease the residue of multi-colour smoke trail.
PT. Tiarangkasa thanked to IDAF which has provided an opportunity to test the smoke trail by using one of The Jupiter Aerobatic Team, KT-1B in Adisucipto Air Force Base, Jogyakarta.
