262 An aircraft with 1020mb set on the altimeter sub-scale departs from Dekelia-Tatoi(LGTT), which is about 800ft above mean sea level (amsl). The flight is made to the planned destination aerodrome in Sparti(LGSP), which is in an area of low pressure, but the altimeter sub-scale is not updated en route. If the QNH at aerodrome of destination, is 999mb, and the highest point on the landing area is 500ft amsl, what should the altimeter read?
Assume 1mb = 30ft.
