The VSL LongEZ POH states "The Long-EZ is equipped with a buzzer gear warning system which is actuated at low power settings with the gear up."
I am wondering if the gear down warning conditions could be slightly more aggressive?
Situation 1: (single warning came very late)
Gear Up, 75 kts, full speed-brake, trim take-off pos, descent rate 300-400fps, rpm 1500-1800
Warning buzzer started around 1250-1300 rpm with manifold press slightly less than 15
Situation 2a: (first warning was ignored because it stopped - wanted to see if/when it would start again)
Gear Up, 85 kts, half speed-brake, trim take-off pos, descent rate 1300fps, rpm 1400, manifold press "between 12 and 13"
Warning buzzer started with rpm at 1400 and manifold pressure of 12.5
Situation 2b: (second warning came very late)
Gear Up, 75 kts, half speed-brake, trim take-off pos, descent rate 400fps, rpm 1400, manifold press at 13
Warning buzzer started around manifold pressure of rpm 1250-1300, man press 12.5
I'm sure there are a number of tradeoffs to be considered in trying to detect a gear up landing situation. If it can be a bit more aggressive about warning, I would feel safer. Could a trigger of airspeed under 87 with gear up be used?
