estimate distance with degree change
almost embarrassed to ask this, but i will anyway,
can anyone give me the equation or magic formula to work out the distance from an NDB when they give you two relative bearings, and time between the two bearing locations and TAS?
i can draw it and get the angles, but the formula for the distance escapes me and i don't have the old books that gave it back in the last ice age flight training.
i have dug through all the books i do have and its not there. have fished the net but couldn't find it either.
i know it must be simple, but to get it clear would help me for the nav tests feb 6th.
another question gave me the DME from the station and asked me to determine the distance between the two bearing locations.
has to be some isosceles triangle thing to it but i'm not related to Pythagaras that i know of.
cheers
