LIMITATIONS
Float inflation pressure:
Minimum float operational pressure is 2.0 psig.
Types of operation:
Night flight over water beyond autorotation capability to ground is prohib-
ited, unless Night Landing Lighting Kit is installed .
Takeoff and landing on water at night is prohibited, unless Night Landing
Lighting Kit is installed.
Environmental operating conditions:
Changes of altitude are limited in accordance with the following.
The water landing site altitude may be at any altitude equal to or higher
than the takeoff base altitude, provided that the descent from the peak
altitude flown does not exceed 7700 feet.
NOTE
: Each float cell has a pressure relief valve nominal setting of 5 psig. If the above
noted allowable decrease in altitude is exceeded, minimum operational float
pressure (2.0 psig) may not be available should the relief valve function at its
lower tolerance limit. This assumes the increase in temperature with decrease
in altitude is the standard lapse rate, i.e., (+) 3.6
°
F per ( − ) 1000 feet.
For takeoff from a high altitude base with the water landing site at a
lower altitude:
If the float pressure
(psig) at takeoff is:
The allowable altitude
decrease (feet) is:
2.0 0
2.5 1300
3. 0 2700
3.5 4300
4.0 5900
4.5 7700
5.0 9500
