Mislanding

What on earth is a 'mislanding' - and how does it differ from a go-around?

Is it some American term? Because I've never heard of it in 35 years and 10000 hrs of (non-FAA) military and civil flight time - yet it came up in a draft document the other day.

Googling didn't find any definition....apart from this:

Mislanding caused by thermal deformation of the shadow mask during CRT operation was effectively improved by an electron-reflecting coating formed on the shadow mask surface. Coatings with high atomic number materials exhibit high electron reflectance and reduce the amount of mislanding by about 40% compared to a conventional mask, when the CRT screen was brought to the highest brightness condition. These improvements in mislanding were mainly due to the energy dissipated by the electrons reflected by the coating. The effects of coating characteristics on mislanding were made clear, and the mechanism of the improvement was discussed.

I read the title of this post and thought you meant "misslanding".

Where is the picture of that lovely flight officer!!!!

I then wondered if you meant "miss handling" but it was not to be.

After some 16000 hours (not a p***ing competition), I, too, have never heard of "mislanding".

Is it another term for a baulked landing which is a go around below DA? We train them although they are more commonly called Baulked Landings.

So is the ATC instruction now going to be,

"G****, baulk your landing, I say again baulk your landing" or even,

"G **** , miss your landing, I say again, miss your landing"

Could this be an above ground abortion?

Mislanding caused by thermal deformation of the shadow mask
And what about the Trinitron!

No it will still be go around, why would they need to change their phraseology? The reason they are given different names is to differentiate between different considerations and possible configurations etc.

BEagle,

It's in the existing AMC and GM to Part-FCL under Exercise 12/13 and 12/13E for the LAPL(A) and PPL(A), and is the usual Euro-guff which has been introduced replacing common useage phraseology.

What on earth is a 'mislanding'
I've come across this term quite a bit recently, to describe any unsuccessful attempt at a landing that led to a go around or a crash.

Thanks, all! I have concluded that it's nothing more than complete and utter bolleaux and we agreed today that it will be $hit-canned from the document.

Sounds like one of those words that are a result of mistranslation.

Mislanding caused by thermal deformation of the shadow mask during CRT operation was effectively improved by an electron-reflecting coating formed on the shadow mask surface. Coatings with high atomic number materials exhibit high electron reflectance and reduce the amount of mislanding by about 40% compared to a conventional mask, when the CRT screen was brought to the highest brightness condition.

Is that CRT stuff still in the syllabus?

I wouls suggest that it is more to do with the operation of a Cathode ray Tube (CRT ) fitted in old style Televisions.

To Quote from Explain that stuff! Science and technology made simple
''The electron gun circuit splits the video part of the signal into separate red, blue, and green signals to drive the three electron guns. or even a single gun in very old B/W systems

The circuit fires three electron guns (one red, one blue, and one green) down a cathode-ray tube
The electron beams pass through a ring of electromagnets. The electromagnets steer the electron beams so they sweep back and forth across the screen, line by line.
The electron beams pass through a grid of holes called a mask, which directs them so they hit exact places on the TV screen. Where the beams hit the phosphors (colored chemicals) on the screen, they make red, blue, or green dots. Elsewhere, the screen remains dark''.

I suggest that the BEags quoted txt refers to improving the performance of the CRT tubes for such developments as wide screen CRTs etc. The electric
current waveforms applied to the coils that stear the beams are very complex (unlike the voltage waveforms for plate systems for engineering oscilloscopes like those you used to see in the Radar /Radio bay). So lots of fine tuning of those beams is required for a high defination picture.
Alternativly this could all be a load of B.....ks.
