Flaps extension and stable approach

1

when i extend my last flaps for landing. i do it after gear down (only the last flap), basically on the final approach phase. i lower my speed to app speed first and then i extend the last flap.

issue im facing is after extending my last flap aircraft pitches up and down wildly, even if i do trim changes. it becomes so difficult to continue on a stable approach (3 out of 10 approaches). any solutions?

I think you were going too slow before you went full flaps so you were trimmed up too much for them. Try going full flaps closer to 150-160 kts. Also from my experience the 777 is a bit touchy on the pitch axis so it will be harder to fly a stable approach.

thank u so much on the advice. i will update u with the differences i feel on the next flight

actually after u mentioned about 777. i kinda realising this happens mostly with 777.

It’s normal for every IF aircraft, don’t worry, but it’s something that should be corrected by the IF team whenever they can.

idk it doesn’t happens always tb, 10 out of 3 for sure.

This is pretty simple. You dropped to approach speed on flaps 15 of course your aircraft is going to have trouble maintaining a stable approach

so ive to configure flaps before approach speed?

Absolutely , you should have your flaps configured before reaching your final approach speed. It should also be incremental , not straight from 15 to 30

thanks. understandable ❤️

another doubt gear down flap 15, this is what I follow.

so i will be around 170-180 IAS at this point, so when / what is the least speed for landing flaps to be extended?

No problem, also if you have a unstable approach like this you should be going around and trying it again

For this scenario try doing this . Flaps 15 at 180kts , 20 at >170kts , 25 at 160kts, 30 at 150kts and then drop to your approach speed which looked like around 141.
