Lear chutes
Way back when, I was driving around in the 20, 30, and 50 series Lears, somewhere in a manual I read where the chute risers were originally designed to pull apart above 256KTS.
Probably a good plan, if it deployed in flight I'm sure it would "rock your world".
Sure was a damn fine airplane once it got used to you.

Trying to remember from class (a few years ago now), but IIRC the Citation 1 (CE-500) even had an optional drag chute.
With ref speeds as low as the high 90s, no power brakes and a nitrogen backup to the brakes I can't fathom why, but.....I'm sure there are stranger things.
Anyone here ever use a drag chute in a bizjet?

Our late S/N Lear 35A is not equipped with one. However, for the general edification of everyone involved:
All factual information courtesy of the FlightSafety Learjet 30 Series Pilot Training Manual.
- The greatest deceleration rate is produced at the highest speed; however, the chute is still effective at speeds below 60 knots.
- The main chute riser attaches to the aircraft at the chute control mechanism just forward of the canister. The loop at the end of the main riser slips over a recessed metal pin that is held in position by spring pressure when the drag chute handle is stowed. Therefore, if the chute should inadvertently deploy (handle in stowed position,) the main chute riser will slip free of the pin and separate from the aircraft.
- In flight
- If the nose gear is not on the ground
- When the indicated airspeed is above 150 knots
- With thrust reversers deployed

I'm just a dumb airline guy that was curious about Learjet drag-chute kits. The other day I was thumbing through a publication that advertises aircraft and noticed that numerous Lears had these kits installed. I actually thought it was sort of interesting. I've never actually seen them in use anywhere, is it typically an emergency-only device? Or was it due to brake-design on the 20-series, etc? Just curious...
The -20 series Lears had good brakes so that was not a factor. I think the chute was included in the -24 and -25 because at that time, the approach speeds were far above what many gen av pilots were used to. While the chute was effective, it was not necessary as many operators just chose to use longer runways.

Chute used for hydroplaning
Three of the four LR35's I fly have the chute. One of our crews used it when they were hydroplaning one day. They were yawing 30 to 45 degrees each way skidding down the runway. The chute straightened them right up.
