In this accident, the generators dropped off line as they are driven by the engines. It was dark. Clearly the RADALT and the Landing Light would greatly add value to an EOL conducted at night OR a relight managed by reference to the RADALT (although at the height he was in this case, this option was technically impossible).
Therefore, understanding the importance of the switch is the first aim. The second is to facilitate a greater understanding of what is important should an EOL become imminent.
The question remains....was an EOL anticipated in this particular instance....or was It a complete surprise?
This reliance upon a RADALT for Engine off landings is not necessarily a good thing....if you are looking out the windows while doing them.
Offshore at night....for sure it is a valuable tool....but onshore over a well lit city....not so much.
If the Landing Light is pointed in the right place....at night that is a real bonus.
In this accident....if the Pilot could not remember the Transfer Switches....what chance he would have had to think of the Load Shed Switch....AND get it shifted and turn on the landing light from the height he was above ground?
