What is a BRAA ?

BRAA is a standardized way to give information about a contact (C) to a pilot (P). BRAA is the acronym of:

  • Bearing : Angle of C to P, it is the heading that P should take to have C in its 12 o’clock
  • Range : Distance between P and C
  • Altitude : Altitude of C
  • Aspect : Aspect of C for P, it could be cold (C is in same direction than P), hot ( C is coming on P ), or flanking ( left right or right left mouvment for P )

By using BRAA everytime, communication is more efficient and faster, pilot is waiting the BRAA datas in the right order.

Example:

group 080 for 120 at 9000, hot

It means that a group of contact is on your 080 degrees for 120Nm at 9000ft and it is hot on you. Same BRAA but faster:

group 080, 120, 9000, hot

BRA also exists, same than BRAA but without the aspect part

BRAA in LotAtc

You can make BRAA in several ways in LotAtc.

Manually

You can use the measure line by using right click to make a line between the pilot and the contact. Measure line label gives you the bearing and the range, get altitude from the contact label, and its aspect and you can give the BRAA to the pilot.

Automatically

LotAtc provides an easy way to doing BRAA.

Maintains Ctrl key and right click on the pilot, then move the mouse over the contact a brown line appears like the measure line, an circle appears on the selection, release the right button.

Then, the BRAA will be stored in the BRAA dock window and will be updated until pilot or contact disappears.

The computed BRAA gives you also the interception line if possible with its bearing and time, you can help pilot to have efficient interception with that (for example to a tanker)

Automatic BRAA can be make to or from :

  • an aircraft/helicopter (AI or human)
  • an airport
  • the bullseye

You can delete it from the BRAA dock window.

If the start reference of the BRAA is a human, you can send him every 10s (go in BRAA options to change that) the BRAA value through the DCS chat system.
