Hi All.
I had some emails regarding the "...three red..." call of Olivia, when they took off with the Herc. Just to indicate to all out there that "THREE RED," means the wheels are up and unsafe for landing, here is a short explanation.
Blinking green lights or red lights indicate the gear is in transit and neither up and locked, nor down and locked. When the gear is fully stowed up with the up-locks secure, the lights often extinguish to follow the dark cockpit philosophy; some aeroplanes have gear up indicator lights, either amber, or red. It is NEVER green, as green indicates that the wheels are DOWN and LOCKED and SAFE TO USE. Red, Amber, or dark, indicate UNSAFE wheels. Some systems even support a sort of silhouette of each gear to indicate when it locks in the DOWN position. The lights are triggered by micro switches in the wheel wells or even on the wheel transition gearbox. When the wheels are UNSAFE, it is neither down and locked nor up and locked.
Some general aviation aircraft have only a lever, marked UP or DOWN. No indication is given if the wheels are SAFE, thus many an accident happened when landing, THINKING the wheels are down, but in fact, the wheels never LOCKED in place for a safe landing. This most often results in a lot of headache or tears, or both.
THUS:
Green = Good.
Blinking, Red, Amber = Not Good.
RED, AMBER, NO Light = Really not Good.
Hope this helps.
Another thing: I have no idea why the part of Dave saying: "... said the spider to the fly...." is in italics. The original upload was good. It must be something with the SOL converter. Sorry, it's out of my control. I'll try to upload a fresh copy.
Stay safe.
Bye 4 now.
