Something to keep in mind when over the mountains, by book values, the P unit will hold 18,500 feet alt on either engine should you experience an engine out. The NA unit will hold about 5,500 feet on the front engine and 7,500 feet on rear engine. Those values were taken from the 1971 F unit. This is why I chose the P unit years ago.
