This is one of mysteries of this "restriction" on the 170. It's very odd that Cessna would placard the gauge and restate it in the owners manual without putting into the Type Certificate or the Flight Manual.thammer wrote:I don't know about 170's but the 120/140 has a one or two page C.A.A approved "Airplane Flight Manual" (not the operators manual) that one of our eagle eye pilots noted contains the 1/4 tank take off restriction in section 1 "Limitations" "(c) Fuel Quantity Gauge - Do not take off on a fuel tank less than 1/4 full."
Maybe at least the early 170's have a similar item in their AFM.
