I am certain there are many IV and IV-P pilots out
there with more experience than mine (100 hr on type, 1000 total time) but I
have been trained by some fellows who have a lot more flying experience, and
they clearly determined two speeds were too low in the POH and the PTM training
manual which many may have read. First, a caveat about our
experience. When doing stalls in training, we found our IV-P did not
stall at the book value of 61 Dirty, rather more like 66 Dirty and not at 69
clean, but more like 75 clean, so this impacted our thinking.
The first was rotational speed. 65 as per POH
was too low, too close to stall for safety. I was taught to start lifting
the nose gear up at 75 - 80 and let it fly off. When fully loaded, 90 is
my speed to begin lifting the nose gear.
The second was base and final approach
speeds. The book speeds were too low for margins of error, so in circuit,
it is 120 on downwind, 110 on base, and only 100 on short final, 90 over the
fence.
Hope this helps the discussion.
