I think we agree it is not normal and should turn it over to the engineers. :cheers:

Mark or the plane?

Shouldn’t do it that much. You have corrosion on a ground to the airframe.

Thanks. I will sqwak it.

Scenario:

Landing on 6,500’ runway. Ref calculated as 102.

At 500’ you are ref +10. Speed bleeds to ref across the fence. Around 200’ feet you notice AOA is indicating “slow” while ASI is on speed.

Air is smooth, pitch feels normal. What do you do?

Land and a call a mentor?

Power up to fly AOA or maintain Vref per ASI?

(No cheating Mark)

Field altitude DA?

Not a jet guy but if pitch and attitude is normal, feels normal looks normal, land normally, TRs and max brake. ASI error?

As Marisa Tomei said in "My Cousin Vinny"... That's a bogus question....ya honah…

If you are on speed crossing the fence, you are at 50 feet... Land.

But if the Pawntiac had pawsitraction… (ahem)

I always went with the donut at the visual point....( but then I wouldn't necessarily go below ref either..) especially with a 6500' runway. Heck I'm retired now anyway....

(but I'm sure this is a gotcha question... So, what's the answer?)

You have to cross check copilot ASI. Otherwise you have a he said, she said.

When was the last time the AOA was checked and or calibrated?

Last 1-4 which is coming due soon I think.

Not a trick question.

I flew it on and all was normal. I was with a highly experienced Citation guy in the right seat and he expected us to drop in due to being “so slow”. Landing was normal.

After some confusion, we realized he was only referencing AOA and I was referencing ASI. I was on speed per ASI and 8kts slow per AOA (approximation).

We have another leg tonight so we’ll fly the AOA down and compare the two ASIs as well.

Based on “feel”, I think we’ll end up fast. He made a good point which was that I should be comparing the two and reacting accordingly.

If you don’t have an ADC miscompare, I’d call it an AOA malfunction. It happens. Pitch, power, speed all seem normal. I’m landing.

Means you are probably heavier then your calculated landing weight unless you are in the wrong flap setting.

At 200’ i would give it a bit of power and land. Vref is between 1.2 & 1.3 Vso. You are not going to fall out of the sky being Vref-5. You just won’t have much energy in the flare so be careful you don’t land hard.
