Hi all,
In the revision test for part 5 [Q30] it says that the most important cue in judging height is [i]texture flow on the ground[/i]. I haven't come across this term before and wonder if it is described or defined anywhere? I can take a guess at what this means but would like to be confident.
Many thanks,
--Nick
Not my area of expertise but you might like to have a look at some of the links in this search -

Thanks for the reply John. I had tried to look up this term myself before posting, and have read through all the front page results on your specific search too.
Unfortunately I must admit I am no closer to a confident understanding of this phrase.
I am [u]guessing[/u] that [b]texture flow[/b] relates to the pilot assessing the approach "...by noting the rate at which the terrain passes beneath him" (pg45, para5). When taken in context of the whole paragraph/page, this is a description of [i]false perceptions[/i] and [i]illusions[/i] (relating to sloping terrain), so I am not sure if I have guessed right and this is in fact the [i]most important cue in judging height[/i] that the revision question/answer is describing.
@bobtait have I missed something here or am I just overthinking things?
Many thanks,
