A300-B4 has a placard in the cockpit giving pitch and power settings to achieve climb, cruise and descent at various altitudes, weights, speeds and flap settings. A very satisfying exercise to do in the sim. The figures do, of course, work admirably, but to button-down and actually do it in a crisis takes some discipline and a cool head while all about is confusing the $%*& out of you.
Do most aircraft have these placards? (Just trying to illustrate that there is another way other than an aircraft flying alongside).
Always assuming your pitch information has not gone walkabout too!
