Landing without PAPI/VASIs
If your FMS has fix pages which take landing rwy as a fix, enter it and put 1nm or 2 nm range rings out to the NPA minima range.
Target alt at rwy is rwy elevation + 50'.
1 mile out target is 320' more to maintain nominal 3 degree G/S (NOT 300´/NM!)
2miles is 640' more than threshold and so on.
Write down these targets in BIG PRINT for both to see in the darkness and hopefully between PF and PM you will be able to monitor the progress towards the threshold after the NPA minima as you drive through the "black hole".
Works a treat on the 73NG but your individual a/c and FMS will dictate.
Same setup keeps you out of smoking hole and/or the office on the rare visual circuit.
Hope this is of use, practise on a good day at familiar field before using in anger?
