Earlier today, Airlink performed a pre-match flyover at DHL Stadium in Cape Town.
Our lowest recorded ADS-B altitude was 50 ft at standard pressure, or approximately 205–210 ft AMSL when corrected for the local QNH of 1019 hPa. With DHL Stadium standing about 164 ft tall near sea level, that puts the aircraft roughly 41–46 ft (12.5–14 m) above the top of the stadium.
