NTSB investigates altitude data
What we know:
In an update on Tuesday, NTSB officials stated that they had been provided with information from Potomac TRACON, the air traffic control facility overseeing the airspace around Ronald Reagan National Airport. "The TRACON fuses information from multiple radar sensors and ADS-B data, providing the best quality flight track data to air traffic control," NTSB officials explained online. "This data showed the Black Hawk was at 300 feet on the air traffic control display at the time of the collision. This data is rounded to the nearest 100 feet."
