I only fly GA aircraft so don't know much about RAA type other than look at a few. From what I can see from that booklet the Brumby does not appear to have a landing light. Also does it have 2 tanks or just 1 behind the seats like some of them. Reason I ask is if just 1 the pilot would not have known he was fuel critical until it was all over given that aircraft fuel guages are usually unreliable. If no landing light to go with that what chance would he have had out in the bush on a dark night to force land? None I would suggest.
