7.9  Full and static pressure system 

The full and static pressure probe (1) (see

 Fig. 12

is located on the left wing strut. It supplies 

the air pressure to the altimeter and the airspeed, vertical speed (if installed), angle of attack 
(if installed) indicators (6). 

This  system  supplies  the  full  (dynamic)  and  static  pressure  of  the  outside  air  to  the 
instruments measuring the flight parameters: airspeed, rate of climb, altitude and angle of 
attack. The system consists of the full and static pressure probe (1) and full (2, 3) and static 
(4)  pressure  lines  connecting  the  probe  to  the  instruments.  Full  and  static  pressure  lines 
have joints  (5) used to disconnect  the lines when the left  wing is removed during aircraft 
disassembly. 

The  full  (2)  and  static  (3)  pressure  lines  are  connected  to  the  airspeed  indicator.  The 
altimeter and vertical speed indicator are connected to the static (3) pressure line. The full 
(2) and (3) pressure lines are connected to the angle of attack indicator. 

Good condition of the full and static pressure system is important for correct measurement 
of  the  flight  parameters  and  therefore  for  flight  safety.  Pilots  must  take  all  measures 
necessary to keep the system in good condition. During the preflight check pilot must remove 
the cover from the full and static pressure probe and inspect the probe and lines to make 
sure that they are not damaged or blocked (by water, ice, dirt, etc.). After flight pilot must 
put the cover back on the probe.
