Hi guys so today i did a flight with the 772 and when i started Decending ones i reached 4000ft the plane started doing something weird the nose was going up and down and loosing speed and gaining speed for example my speed was 40%it then when up to 60% and then down 59 40% again why is that and i stall ones because of it.
What was your flap settings and speed?
220 and i had flaps 15°
Your speed auto pilot was probably set and your flaps weren’t down enough and you stalled
GS or airspeed
That should be fine!
It doesn’t really matter at 4000.
Do you know your airspeed?
Just googled the 772 flap speeds. You seem to be 5 knots faster for 15 but that shouldnt be an issue
Was A/P enabled?
I don’t think so
yes it was
i though about my weight but it was just fine 5%
Sharing your replay would be great, it is easier for us to see what exactly was happening.
Ummmmmm? Has this issue been fixed?
Well if you read the last 5 messages, you would’ve seen that no, it hasn’t been fixed.
Well yeah I am sorry he chose the previous post as a solution and then removed it just now
I have read the last messages.
This could happen if you were descending very fast (>-1500 ft/min) and then all of a sudden leveled off. This happens when you activate VNAV. Make sure to always be present during your descent to monitor both lateral and vertical speeds.
