i read a somewher about the thunderbird f-16 near crash in october of this year or last, and the mistake happend because the pilot didnt zero out his altimeter. but wouldnt that make it worse beacuse the airfeld was most likely not at 0 feet and if the altimeter showed 5000 ft it could of been only 1500 above? so could someone please explain why they would zero out their altimeters. and they also said that it would be easier to calculate they above alt. with the altimeter at 0 rather than set to the airfield alt. and whats the dif between MSL and actual Alt.? and one last thing, is the AGL the same as actual alt.? thanks alot. heres the link to the thread at fsnetwork, http://www.flightsimnetwork.com/dcforum/DCForumID2/7500.htmland hers the articlehttp://www.f-16.net/f-16_news_article968.htmladam
