The asost emoa cause of HeIia crsahe~ and major daarage -- though
nmmr with s~iatss fnjuxy to occupants --
has been from efforts to
pull the aircraft off the ground prematurely at toa law B speed
and/m roactirr;ntly to try to cltaab aut with tao low an airspeed
psith flaps dcwa se that the remlting high-drag exceeda the re-
drtced thrust ef the propeller a;t km fmrvmrd Bpeeds, Thus, with
power full-on, the rafrcr~ft my either sink ?mck ta the ground
or fail ta clear otherwfiae -joy-sasaaoontable sbstactes.
It takes considerable expcricn~e ta rscogaize the point at which
I
the nose high attitude starts to reduce the rate-of-climb aad then
may finally progmss to an actual rate-of+fnk despite full power.
This condition is often referred to am **the back side”* af the
thrust drag curve, or simply as
“the back side rof the mer curve”.

With 30 degree flaps alluw the aircraft to accelerate as quickly

MPH, fly the ieircrsft off by applying the approprfPte back pxe8-
msre on the elevator until it is airborne, Permit the sirsaecsd to
build up for rpprcmimatalg two mxands au abaut 50 MPH, then begfn
rotation to the point that will climb the aircraft over the barrier
without further build up of airrpted.
After consfdtrable txperi.mcel ewea shorter barrier diatanee can
be attained by hoEding the aircraft to about 30 MPltI &n a smooth
ruuwuy and then %omimg** over the barrier at an amble sufficiently
steep to clcrar the barrier without lass of airspeed after whfch the
~~cme can be lowered and the nmma rate-of-climb airspeed attaiaed.
Grcrt skill ia: n6Ctssary,
