Is that the time-of-flight tape on the right side of the HUD in air-to-air (missile) mode?

[Sarix]

When using air-to-air missiles and locking a target with the radar, does the right-hand (orange-colored) tape signify time-of-flight?

In my experience using the S350F and the R.530 it appears to be stuck on approximately +440 and +250 until I reach the employment envelope (green light on the HUD), and then starts counting down. Screenshots attached, head-on against Il-76, approximately Mach 1.5 closure rate. Can provide a track if needed.

Correct, only with radar missiles and R530IR (if there's a radar lock).

Awesome. Are there plans to include this (the orange tape being the time-of-flight indicator) into the manual in the future?

It is included in our flight manual internal version.

What unit is the tape in? Seems too high to be time of flight in seconds.

Distance/heading scale: this scale reads distance or heading depending on the mode selected. Distance is read in NM for large distances, and in hm (hectometers or hundreds of meters) for distances ranging from 0 to 3500 m.

Closing speed, target aspect angle or missile flight time scale: If the radar is locked, a graduated closing speed scale from -100 m/s to +600 m/s appears in orange when using the (C + M or SW) R mode. When using cannon mode or A/A short range missiles it shows target closing velocity. When using 530 missiles it represents:
◦ before firing: missile flight time
◦ after firing: the time remaining before the break-away.
10 units represent 1 second.
