FTA Exposure Time Question

[ptc-4810289]

When I want to specify an exposure time that is shorter than the flight time in an SAE fault tree. Do I divide the time by flight time, or 1 hour.

Ex. my exposure time is 3 minutes, my Flight Time is specified as 2.14 as in hours.

So is the Exposure time = to 3/60 or 3/(2.14*60)

Jennifer. I'm new to the community, so I did not see your question earlier. I believe your 3/(2.14*60) is correct. I am using the same formula for exposure time in my FTA's.
