Just wanted to make a quick topic regarding some of the cruise profiles of the A330. I’ve personally had a few PM’s regarding violation removal due to their aircraft stalling in cruise. I would like to make it clear that moderators and staff members alike cannot be removing violations when you stall a heavy aircraft at an altitude above what the aircraft is capable of.
When the aircraft stalled, the autopilot kicks off because of excessive bank/pitch angle turning it off as initially designed. I wanted to clarify that when you’re heavy, it may not be possible to get up to your cruise altitude initially. Below you’ll find a quick table to reference when deciding what altitude to cruise at.
The A330 is a bit more sensitive to weight and altitude than what you would find in the B777 or other similar sized aircraft from what I’ve tested. 19.1 also made a few minor changes to the engines as well. The altitudes and the weights that you were flying pre-19.1 may be different than what you can fly now.
To break the table down in a simple manner, its broken into 3 weight classes. Light, Normal and Heavy. Each of these weight settings can be found under the weight and balance setting. I’ve listed each weight class with the weight in both (lbs and kgs) as well as the aircraft load percentage. At each of these load percentages, I can guarantee you with 110% confidence that you will not stall or crash at the altitudes in level flight while using the speeds specified in the table. that’s a pretty bold statement if I must say. Pun intended 🙂
Now you can change the passenger, fuel, cargo load as you wish. Just keep in mind that once you leave the specified aircraft load and leave one of the altitude ranges listed below, my statement does not carry any value. The altitudes are recommended Flight Levels for the aircraft load. You may deviate from those altitudes on your own will but it may result in poor aircraft performance. Do that at your own risk. 😉
|Weight:||348,015lbs (157,857kgs)||409,845lbs (185,903kgs)||471,681lbs (213,951kgs)|
|Altitude||FL380-FL410||FL360 and lower||FL340 and lower|
|Speed:||M.78 - M.80 (Max M.86)||M.78 - M.80 (Max M.86)||M.78 - M.80 (Max M.86)|
*Service Ceiling of the A330 is roughly 41,100ft
On longer flights consider the linked topic below to get to higher altitudes if you’re unable to get to your desired cruise altitude right away:
Hope this helps and provides a little assistance when flying your new birdy.
