Lesson 10 – Hazy lesson on circuits

Firstly before getting into the lesson – answer to Steve’s question on Headng Indicators

The Heading Indicator uses a a gyroscope to give a direction indication. Generally it does not have a auto north-seeking sensor so you have to align it manually with the magnetic compass before flight. This is what the instructor was doing on your trial flight. The heading indicator reads the same as the compass but with the trailing zero removed i.e. 36 = 360 deg.

Apparantly is much easier to use than a compass so is the primary instrument for setting headings. Having read up a bit on the instrument – I now feel a bit more confident about how to use one!

The lesson

Once again the weather was difficult for circuit flying – there was a temperature inversion (condition in which the temperature of the atmosphere increases with altitude in contrast to the normal decrease with altitude – this is ideal condition for trapping pollutants). This meant there was some smog-like haze on the circuit which meant that it was very difficult to see – so once again I felt disorientated. Only did two circuits – both approaches were too high and – needed help with both landings.

too high – reduce power and pitch nose down – maintain 70kts

Learning Points
  • Apply rudder when applying full power on the runway – otherwise can veer to the left
  • Use heading Indicator to help keep idea of direction
  • need to almost raise nose to full extent to stop landing on nose wheel

Heading for left hand circuit of Coventry Airport. However these are ideal headings – if I overshoot on one of the legs especially the base leg – the heading could be different to get back on course
