APEX main Tanoa runway is about 2/3's the length of Altis's main runway.
The A-143 GROUND CAS jet usually requires no more than 2/3's the length of Altis's runway, and yet the A-143 GROUND CAS jet fails to even lift-off it's belly from the APEX Tanoa runway.
There seems to be scaling error somewhere.
(Version 1.68)
(Going from memory, the A-164 substantially reaches take-off speed with using only 2/3rd's of Tanoa's runway fully loaded, but with two turbines instead of just one.)
I have tested this several times, and this just doesn't make sense.
Bottom line, the A-143 GROUND CAS jet, although a preferably used jet versus A-164 for game playability, is currently useless within the Tanoa map.
TIP: If the player aims the A-143 CAS jet towards the left side of the Tanoa runway (while taking-off seaward or south), the jet will likely avoid the runway posts and bounce into the air after hitting the rocks if the nose of the jet is high enough into the air. The jet is then slightly airborne above the water surface, allowing the jet to further increase lift just enough to become further airborne with continuing lift.
