The effect is to increase the airplane's tendency to roll off abruptly in a cross-control stall
. A cross-control stall
in those airplanes can mean a loss of several hundred feet even if the recovery is done precisely right.
In addition, when excessive back-elevator pressure is applied, a cross-control stall
But so long as you keep the load factor low, you have a buffer over a cross-control stall
. Tip: Lift the nose a bit as you roll in and apply that top rudder early.
We consider ease of coordination a safety factor when maneuvering at low speed as an inadvertent stall is bad enough--a cross-control stall
almost guarantees a significant wing drop and incipient spin, dramatically increasing the altitude required for a recovery.
But a cross-control stall can result if the combination of low altitude and poor training tricks a pilot into holding a constant bank angle while trying to increase the turn rate with additional rudder input.
The Airplane Flying Handbook again: "In a cross-control stall, the airplane often stalls with little warning.
Unchecked, a cross-control stall
is an easy way to put the airplane into a spin.
So can a skidded turn on to final approach with a cross-control stall
as the final event in that fatal-accident scenario.
A cross-control stall occurs when--as its name implies--ailerons are deflected in one direction and rudder is in the other.
But--and as the accident record demonstrates--other types of stalls exist, including accelerated and cross-control stalls. Detailed examinations of these two variants are somewhat beyond this article's scope, however.
When maneuvering at low altitude, a cross-control stall
in one of these airplanes can be a killer, so much so that it long ago earned the title of "moose stall" (in honor of all of the late Alaskan pilots who hit the ground after a cross-control stall
when flying at low altitude to eyeball wildlife).
As long as you keep those cross-control stalls
in the front of your mind, the Champ loves to slip and landing is fairly simple.
