Incident at J.A. DOUGLAS MCCURDY SYDNEY AIRPORT (ATM - weather observation systems)


2014-11-13: On initial contact with Charlottetown radio, an aircraft was given a wind and altimeter digital display system (WADDS) altimeter of 29.82 but pilot questioned this as he had just received an altimeter of 29.88 from Moncton, NB (YQM) ACC as per the 1422Z Sydney, NS (CYQY) aerodrome special meteorological report (SPECI). FSS called the contact weather office (CWO) at CYQY to verify the altimeter. The CWO advised that he was replacing the dew cell which may have led to incorrect altimeter readings. The altimeter on the 1500Z CYQY metar corresponded with WADDS data.CYQY SPECI 1422Z 21012G24 15 SM BKN005 RMK ST7CYQY METAR 1400Z CCA 20014G25 15 SM -RA FEW006 BKN050 BKN067 13/12 A2988 RMK ST2SC7AC2 SLP118
