We departed again early in the morning with light fog
around. During the start run the airspeed rised up slowly although the feeling
of the acceleration was normal and we were airborne with only indicating 40
kts. The runway was too short to abort the take-off. We had enough fuel on board to fly the whole way of 2500 km non-stop.
I decided to fly 4 hours without airspeed indicator to our alternate airfield. The
runway in SNGI was long enough to make a safe landing. I made the landing with
my common power setting and flew the approach with the AoA (Angel of Attack).
After landing I checked the pitot tube and found out that there must be an
insect inside that blocked the tube.
It was Sunday and nobody on the airfield was here to help us
with tools and a compressor. After a while somebody arrived and we could get
access to compressed air and tools. I was able to blow the insect from the
instrument side out of the tube. But it was too late to continue our flight.
