Sure!, if you fly to, let's say HLLM/MJI, and you wanto to fly Jeppesen chart 23-2 (2 VOR Rwy 29), when you study your plate you find a "CAUTION: PROCEDURE UNDER EXPERIMENTAL BASIS." note, right in the middle of the chart. Do you just go ahead and shoot the approach?, do you consider any limitations in terms of nav aids, weather...?, why?, any documents or references where to look in order to make the right decision?
