Skydive flight at Teuge 20-04-2008

Post by Jerrie »

Hello everyone!

A friend from my brother was going for a skydive, at Teuge airport!
My brother and I were lucky, there was space for 2 extra persons in the aircraft, so we made a very nice flight!
The plane we were flying with: PH-JMP Cessna Caravan:

Inside:

Very nice view at around 9000 feet:

After everybody was outside, we made a freefall with the plane, for around 10 seconds
The altitude was 12000 feet, and after less than 5 minutes we were making our touch down!
During a steep turn (look the horizon on the cockpit) Sorry for the moving picture, but there were a lot off G-forces

Another Skydive Caravan, with a departing Cessna in the background:

Enjoy the pics,
But the pics aren’t that cool than the experience to lose your weight in a flying aircraft!

Greetz,
Jerrie

I made a skydive myself once, a great experience! :D I see the PH-JMP making a very steep descent very often, it reaches the ground earlier than the parachutists comming out of it! Nice pics! :D

Nice bit of info: I believe Cessna Caravans can reverse their propellor thrust while making a dive to keep it below overspeed limits, this is why they can dive (almost) vertically.

I dont think he didn't do it like that..
He was flying with a very low airspeed to drop the jumpers, and when the last one was out of the plane, he dive with the trottle idlle till an alarmbell was beeping. (I guess overspeed). It was after around 10 seconds.

If that is true, nice feature, but i think also a bit dangerous; what if the prop thrust stays in reverse and won't go back to idle? That must mean an almost 100% chance of disaster!

Love the artificial horizon position, also nice to see the vertical speed indicator :lol:
Nice pics Jerrie!

If, If, in aviation it is "normal" that alars bells gonna ring. Offcourse it is better that it didn't happen but it is a sign for the pilot to not continue his/her current setting. The propeller pitch is controlled by a so called governer system which regulates the pitch by hydraulic mechanical power. This governers reacts to the speed of the propeller. To keep it short, a momentum is created in a governor this mechanical device reacts directly to changes of the propeller. To keep the propeller speed constant it changes the pitch by hydraulic power. This is why this type of governer is also known as constant speed drive.

Almost all aircraft are equipped with such a device on the propeller, except for the real smaller ones and aircraft with poor pilots ;)

kind regards Maarten

I know that, however as far as i know, the beta range, or ground fine pitch of a propellor, can only be selected when the airplane is on the ground, by selecting reverse thrust. It cannot be selected during flight, because the reverse thrust range of the thrust lever is blocked. Therefore it seems as a surprise to me that on the Cessna Caravans it is possible.
