Several challenges face the new Lancair pilot. Please approach aerobatics v=
ery carefully. My Lancair 4P has a much higher wing loading, intended for c=
ruise performance. You will notice the Pitts and most aircraft designed for=
 aerobatics have very low wing loading, often with two sets of wings.
=A0I believe spatial disorientation is often a factor when these planes 'de=
part' controlled flight. Rotations and accelerations can be violent, depend=
ing on the airframe and builder technique. This is usually only a problem, =
in VMC, in military performance airplanes, so there is less training and ex=
perience, in the certified civil fleet.=A0 When the pilot is so disoriented=
, that they cannot even see instruments or horizon, it's not that they free=
ze up, but they just can't figure out what happened or what recovery action=
 to take. We called this type III Spatial Disorientation(SD). Type I is pri=
or to recognition, and type II is after the pilot recognizes his disorienta=
tion. In addition, being untested in spin modes, the departure may become a=
n unrecoverable stabilized spin, after a short period. Sometimes recovery i=
s only available by immediate action, which may elude the most experienced =
pilot, if they are surprised by the departure. All this is aggravated
 by the accelerated stall with high G loading.
=A0I think the two main killers of over 150 souls in the Lancair experience=
 are thunderstorms and low altitude stall-departure-spin scenarios, often w=
ith related engine failures or "magic turn" attempts.=A0 Stay fast in the p=
attern, even if you have to make a couple of circuits at pattern altitude, =
to let the "low wing loaded" get on the runway. Keep a visual sep of 10-20 =
miles from the cumulonimbi. The thunderstorm scenarios are SD departures wi=
th Ice and extreme turbulence and hail included. Join us at the LOBO meetin=
gs and training. Especially, talk to a LOBO or HPAT instructor about aeroba=
tics first.
