BRAA gives pilots a fast visual way to understand where another aircraft is, what it is doing, and how it is positioned relative to your own aircraft.
At cruise and flight levels, pilots continuously hear traffic, turbulence, chop, weather, and ride-condition reports over the radio. A crew may hear another aircraft report moderate turbulence, rough air, or changing weather ahead and immediately ask:
Where is that aircraft?
Am I heading toward that area?
How far away is it?
Is my ride likely to deteriorate?
Is that traffic crossing, flanking, converging, or moving away?
Radio calls are valuable, but they are audio-only. ATC may call traffic as “northwest, 120 miles” or “330 for 120,” yet the pilot still has to build the mental picture manually.
BRAA is built to solve that problem.
BRAA converts aircraft position data into a pilot-centered picture of bearing, range, altitude, aspect, and intercept-style geometry. Instead of only seeing a map dot, the user sees the target aircraft in practical aviation language, relative to ownship.
Think of BRAA as a GCI-style, “bogey dope” inspired awareness tool for civil aviation: bearing, range, altitude, aspect, and relative geometry presented in a clean iOS interface designed for quick interpretation.
Key capabilities include:
Airline and flight-number lookup
Bearing from ownship to target aircraft
Range in nautical miles
Target altitude display
Aspect interpretation (beam, flank, track relationship)
Ownship position reference
Map-based relative visualization
Test-position mode for training and demonstration
GPS-based ownship reference
Dark cockpit-style interface
Large, readable numbers for rapid scan
BRAA also introduces CATA: Collision Antenna Train Angle.
CATA helps visualize the heading relationship between ownship and a selected aircraft. It can present heading concept, projected merge point, estimated time to intercept, and whether an increased-speed scenario could reach the target aircraft under the current geometry.
The white X marks the projected merge or intercept point. Time-to-intercept helps show how quickly the geometry is changing. Additive speed values such as +100, +200, or up to +600 knots (MACH 1) represent increases over the current ownship speed for training, demonstration, or tactical geometry analysis.
This helps answer common pilot questions:
If I maintain course, will I cross that aircraft’s path?
If I speed up, could I catch it?
Where would the merge occur?
How long would it take?
BRAA is useful for:
Airline pilots building spatial awareness
Student pilots learning bearing, range, aspect, and relative motion
Flight instructors teaching traffic geometry
Aviation enthusiasts tracking airline traffic from a pilot’s perspective
Dispatchers, analysts, and aviation professionals who want more than a basic map
Pilots practicing intercept geometry, closure concepts, and relative positioning
Most tracking apps show aircraft on a map. That is useful, but pilots think in bearing, range, altitude, closure, aspect, ride reports, weather reports, and relative motion.
BRAA bridges that gap.
It turns aircraft data into a cockpit-style tactical picture that is easier to understand quickly.
BRAA is not certified avionics and is not a replacement for TCAS, ADS-B In, ATC instructions, onboard weather radar, approved navigation equipment, or operational decision-making systems. BRAA is a situational-awareness, education, visualization, and training tool.
The core pain BRAA solves is simple: pilots hear useful information but do not always immediately know how it relates to their aircraft. Is the other aircraft with a bad ride or asking for deviations in front of me, and if so, how far? Or are they no factor?
BRAA eliminates that guessing.
Built for pilots.
Designed for fast understanding.
Focused on the geometry that matters.
It is all about the angles.
