The angle of attack is the angle that the wings are cutting the air at the learjet is good at 1800 ft per minute When the plane is going up the gauge is should read within 1800 sometimes it can go to 2000 try to keep that gauge smoth and steady for the passengers sake .

And, the AOA indicator is a splendid tool to make sure you're flying the vref+5 approach speed. In real life, just keep the needle centered aorund the green band (3 degree range) that will show up when aircraft is in landing config.

If It Was Good Enough for The Wright Brothers...

An angle-of-attack indicator is needed in the cockpit of every airplane. "It's the most useful piece of information you can get," declared Capt. Ron Rogers, an A320 pilot. Rogers, who is also director of aircraft development and evaluation programs for the Air Line Pilots Association (ALPA), was speaking recently at that august organization's annual safety meeting.

In two days of discussions about runway incursions, simultaneous offset instrument approaches, "hard" and "soft" control limits on Airbus and Boeing aircraft, and other safety issues of the day, Rogers' remark struck a nerve. Of the thousands of words uttered at ALPA's two-day safety symposium, Rogers' call for an angle-of-attack indicator was the only one that generated spontaneous and fervent applause from the large meeting hall full of pilots.

The measure is so critical that the only flight instrument on the Wright brothers' first airplane was a device to measure angle-of-attack. The Wrights' crude instrument consisted of a stick protruding forward of the wing's leading edge - and clear of the airflow around the wing - with a length of yarn attached to the front end. In flight, the angle-of-attack was easily measured by the position of the yarn streaming back relative to the stick.
