NYC's East River is about 2000' wide. So when you approach the north
endpoint of the VFR corridor there, you need to make a U turn with a 1000'
radius (or less if you're not right next to the eastern shore when you
start
the turn).

Suppose you're afraid to fly too slowly because you don't want to stall
during the turn, so you cruise up the river at 90 knots. Suppose you're
afraid to bank too steeply because you don't want to stall during the
turn,
so you use just a 30-degree bank.

Oops: your turning radius is about 1200'.

Using the East River VFR corridor requires planning the turn
carefully--especially since you need to leave an extra margin in case you
have to dodge high-density traffic there.

only have to increase bank to 36 degrees to get under 1000' radius ( or
slow to 81 kts) or go half way and 33 degrees bank and 85 kts. shouldnt be
a problem in a 172 ( isnt that what you fly?) stall speed would still only
be 55 kts. ( assuming 50 kts strait and level from memory)
