2.Operating restrictions
2.1. Restriction of the speed of the flight and reparation of position fault of air-speed
recorder
Presented speeds of the flight applies to the maximum take off weight of 450kg and at the
conditions of the sea level by the MSA. The speed are presented in kilometers per hour.
Take off speed 75
Climb speed 130
Travel speed 180-220
Accession landing speed 120
The speed of bearing the surface 62
Maximum speed of horizontal flight 25
Never never-exceed speed Vne 275
Maximum speed at turbulence 180
Stalling speed with no flaps 80
Stalling speed with flaps 35degrees / 2
nd
grade flap / 62
Maximum speed for extending the 1st grade flaps Vfe 140
Maximum speed for extending the 2nd grade flaps Vfe 120
Vne is the never-exceed speed which the airplane can not fly
Vfe is the maximum speed for extending the lifting flaps, there are the same speed restrictions
for the flight with extended flaps as for their extension.
2.1.1. Air-speed recorder data reparation regarding the position fault of Pitot tube
Harming the by –passing in the area of placing the Pitot tube can run short that the speed data
indicated by the air-speed recorder do not correspond at all speed to the real aerial speed.
That´s why we do introduce the reparation of the indicated values for couple of the speed ranges.
The real speed is at about 6.3% - 8.2% lower than the speed indicated by the board air-speed
recorder. At low speed the relative mistake is lower and at higher speed the mistake is increasing.
For security reasons / not extending the maximum allowed speeds /we choose the type of lower
real / calibrated / speed than the indicated speed.
All speed limits introduced in this guidebook as operating restrictions are initiated as the speeds
indicated by the air-speed recorder. There is no need for any recount in the way of functioning of
the airplane.
