and the nose gear.  In the event porpoising action starts, you may not catch it by using pitch control alone.  Because of lag and slow response of the stabilator from stop to stop, you may be one step behind the oscillation and increase the severity of the bounces.  The best remedy for a porpoise is an immediate go-around with maximum power and the control stick slightly aft of neutral.

Any of the above situations, if allowed to develop, can place you in a nose-high stall situation.  If this condition is encountered you can expect wing rock immediately followed by one wing dropping in due to loss of lift. This may cause wingtip contact with the runway and further aggravate the situation.  Should wing rock start to develop, it is imperative that immediate and positive action be taken.  Maximum power should be selected and back pressure released to allow aircraft acceleration.  Use of rudder at low airspeed is highly effective in maintaining directional control but you must use caution to not over apply it.

A landing irregularity, if not correctly handled, may place you in a potentially hazardous situation.  Although the best initial course of action is usually a go-around, the pilot should always keep in mind the option of aborting.  This decision will depend on the exact situation and would encompass such factors as aircraft position, airspeed, and remaining runway.
