In the last few days we have lost 2 pitot heaters on club a/c. They can no longer fly IFR now...and therefore we cannot perform IMC training in IMC conditions.....this has thus reduced the effective usuability of the aircraft.
Now if they have gone thru normal use fair do...but if it was through bad practice then it means people are having lessons or flights cancelled when the situation was avoidable.
Ho hum.
