Q3.An a/c is flying at 400ft from a high temp area to a cold temp area where the temp diff. is 20degree. what will be actual height of a/c:
Ans-3680feet
{As we are going from low density to high density area........the true height should decrease right!....i get that point but how to calculate barometric error......because QNH is not given
....only temprature diff of 20degree is given.........plz explain}
