Despite scorching heat and average tarmac temperatures above 50 degrees Celsius during flying hours, IAF technicians ensured a very high availability of aircraft for all exercise related requirements, during exercise Red Flag at Air Force base, Nevada, USA. The exercise concluded its operations on 23 Aug 08. During extreme heat conditions there is a tendency of the flying machines to develop snags such as leaks in hydraulic systems, engine oil, gear box etc. The performance of avionics system also becomes erratic as integrated circuits develop problems in extreme heat conditions. However due to proper planning and hard work of IAF technicians, aircraft serviceability was kept high at all times.
