Another part of the PPL syllabus is demonstrating that you can
recover from a spiral dive.
Without crashing.
Or breaking the plane.
The last one isn’t much of a joke, you get very very close to
redlining your airspeed. Red line = Vne (never exceed speed). After this
speed the manufacturer can’t guarantee that bits won’t start falling off of
your plane.
My previous exposure to them has been two fold, if you let the nose
drop during a steep turn then you can quite happily end up in one fairly
quickly. That one happens to most students the first few times they try them.
The other method I’ve come across is if you get distracted (Bob’ll get me to do
some pointless map reading, other instructors favour the “oops, I’ve dropped my
pencil” routine), again it is easy to let the plane bank and the nose drop.
Last lesson though Bob introduced a new one, the failed spin entry.
Spins are very different beasts to spirals. In a spin you are
stalled. In a spiral you are most definitely not. The recovery technique is
very different. Try the spin recovery for a spiral dive and you are in all
kinds of trouble. The airspeed is the key.
But this particular entry method is nasty because right up until
the moment your ASI zooms towards the red, you think you are going to stall. I
was certainly convinced.
I was 100% certain that Bob was lying to me and was about to put me
in a really nasty aggressive climbing turning spinning stall. Until the nose
went over and he called “recover”. Literally the ASI went from the “so-low-that-you-are-going-to-stall-any-minute”
end of the arc to the “oh-man-you’re-gonna-break-the-plane” end, I swear without passing through the space
in between.
If I didn’t know that spins aren’t on the PPL flight test, I would
have been convinced that I was in one and done all the wrong, potentially plane
breaky things.
In the blink of an eye you can go from one extreme attitude to
another, you really need to be sharp and watch what those instruments are
doing.
I think I’ll be okay but it truly shocked me how quickly the
airspeed started doing crazy stuff.
