Bearing Range Altitude Aspect vs EF1 E6B Flight Computer

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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

EF1 E6B is a complete electronic flight computer built for student pilots, CFIs, and certificated pilots who want a fast, offline, modern E6B without the bloat. EVERYTHING AN E6B DOES - FASTER • Wind triangle (heading, ground speed, wind correction) • True / calibrated / equivalent airspeed • Density and pressure altitude • Time / speed / distance • Fuel burn, endurance, and range • Standard atmosphere + lapse rate • Compass + magnetic heading with deviation and variation • Reciprocal headings, pivotal altitude, standard rate turns • Off-course (1-in-60) corrections • Climb / descent rates and ground distance • Cloud base, glide distance, holding pattern entry • Linear interpolation • Universal converter (length, mass, volume, speed, temp, pressure) CROSS-COUNTRY PLANNING Build a full multi-leg route with up to 20 checkpoints. Set true course, distance, wind, TAS, fuel rate, MSA, and frequencies for each leg. Drag to reorder, duplicate, or reverse the route in one tap. Choose VFR or IFR mode and the app applies the correct FAR fuel rules: • VFR: 30-min day or 45-min night reserve, optional alternate • IFR: 45-min reserve, alternate-required toggle, alternate fuel auto-computed from distance to alternate Trip totals show ETE, ETA, fuel legality (LEGAL or NOT LEGAL with margin), and per-leg fuel remaining. PRINTABLE NAV LOG Generate a clean PDF nav log — VFR or IFR titled — with every checkpoint, fuel breakdown, frequencies card, and a side panel showing usable fuel, taxi, climb, enroute, alternate, and reserve. Email, print, or save it. FLY THE CROSS-COUNTRY Tap START FLIGHT, then mark off each checkpoint as you pass it. The app records actual time enroute, actual ground speed, and ATA, then writes them back into your post-flight log automatically. WEIGHT & BALANCE Build aircraft profiles, enter station moments, and check CG against the envelope. DESIGNED FOR PILOTS • Works fully offline - no signal, no problem • Optimized for iPhone and iPad with dark cockpit theme • Adjustable font scale for kneeboard readability • US or metric units, switch any time • Save unlimited routes • Backup and restore your data SUBSCRIPTION The EF1 E6B unlocks all features with a 7-day free trial, then $3.99/month or $19.99/year.
