BUFFET ALERT

 

Current conditions result in

a maneuver margin less

than specified.

 

 

Bring the airplane back

within the operating

envelope

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.

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).

I got it by being above the maximum altitude. I requested lower level, and the warning disappeared. Like you said.

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.
