When I was a kid, I went to an airshow and saw a maneuver that I thought was spectacular and wondered if it's still being done. If memory serves, it was called a Vertical Reversement. The pilot rolled 90 degrees to a knife edge and applied hard bottom rudder. The tail would describe an 180 degree downward arc, the pilot would roll level effectively doing a 180 degree change of direction in a *very* small space.

Is something like this still done and what is it called?

BTW, for those that missed it, the chat with Patty Wagstaff, Dale Snodgrass & Mike Mancuso was a lot of fun! Look forward to the next one!

Thanx,

I haven't seen that manuever done exactly that way (I am understanding that the rudder pitches the nose down and around in knife edge). In a way it sounds like a "split-S" but it (split-S) isn't done in knife edge, the pilot rolls inverted and pulls through to level.

I have seen Patty do a manuever I like where she pulls up in a quarter loop. At the 90 degree point she rolls 90 degrees to knife edge and then uses the rudder to more or less do a wing-over to a 45 degree downline, where she rolls level.

Not sure why but I like to watch that one.

In this case the nose pitches up and over the knife edge - the tail describes a lower semicircle.

I like to watch just about anything that Patty does ( Sorry, Dale!)

Can you believe that the technique for a Vertical Reversement is clearly outlined in, of all things, a Cessna 152 Aerobats POH?

I know this because I was flicking through one the other day trying to work out what the hell one was...it appears on the "approved manouevers" placard in the 152s I fly so I decided to look it up!

Anyway, from memory, the Vertical Reversement is basically a half snap roll initiated during a steep turn. Ie roll and perform a steep turn to the left, pull hard/stomp rudder, and the aircraft will start to snap roll. Recover from the snap and continue turning in the opposite direction.

I've snap-rolled 152s plenty of times so am keen to try one...
