August 22, 201213 yr what does it means when I see the "BUFFET ALERT" on the scratch pad of the CDU? what action(s) should be taken? Joel Strikovsky
August 22, 201213 yr BUFFET ALERT Current conditions result in a maneuver margin less than specified. Bring the airplane back within the operating envelope Agustín Contreras B737-8AS FO

August 24, 201213 yr thanks. you're probably going to fast or too slow :huh: Best RegardsMarc ManandiseWindows 10 PRO
August 24, 201213 yr Hi, Basically it means: Bring the aircraft back within its limitations. (Example: The higher your aircraft is above optimum altitude, your buffet margin gets reduced. Realistically, you don't want to climb to your next ICAO flight level until your opt alt is within 1,000ft.) So, it means the current conditions have resulted in a maneuver margin less than whats specified on your Perf page. what does it means when I see the "BUFFET ALERT" on the scratch pad of the CDU? what action(s) should be taken?

August 24, 201213 yr Author Thanks Mike.. and all of you. I'll look at the flight log and see what was the cause , I think it was speed (to fast). Joel Strikovsky
August 24, 201213 yr Example: The higher your aircraft is above optimum altitude, your buffet margin gets reduced. I got it by being above the maximum altitude. I requested lower level, and the warning disappeared. Like you said. Best regards Cristiano Mueller
August 25, 201213 yr Hi. Basically its a game with speeds and altitude. If you climb to a higher altitude you have to increase True Air Speed TAS to keep constant or increase Calibrated Air Speed CAS because air density decreases, but if you increase your TAS your Mach number increases. You have to maintain your speed between a lower and higher limit. keep in mind as your altitude increases the margin becomes narrower. Also every turn, moves the numbers closer to each other.
