All well and good, and great information here, but in practical terms, what should a pilot do to make these corrections and when should he do so?
On the ILS the error at 200 feet is not large. Provided the airfield has an inner marker, DME etc, and the airplane has a radio altimeter, there is no reason for the airplane to be in jeopardy. Applying the corrections for this situation is also easy.
The danger comes about in the intermediate approach phase, where the airplane is in close proximity to terrain. Under these circumstances the pilot should be aware of the errors and should make the required corrections, advising ATC of his revised altitude.
The radio altimeter will help to maintain a safe altitude and should be included in the cross reference. I have not seen this mentioned.
But in many cases the approach is not limited by terrain (eg where the airfield approach is over the sea or has no hills in the area) and therefore not applying the corrections would not put the airplane in danger.
Perhaps the procedure for applying corrections for low temperature should mention this?
