Newbie Question, Plane Speeds

Recommended Posts

Hey I was wondering what speed in mph planes would be traveling on exit? Anyone know the approx. speeds for king air, Cessna 182, twin otter, skyvan, and caravan when on the jump run?
Just curious about something that hasn't come up in training

No I wasn't. Although it was C205 which i was referring to (i just checked :) the plane specs are quite similar so you might be right anyway.

I did a little research and thats what i found:

Twin Otter: 85kts / 98mph / 157kmh
AN-2: 65kts / 75mph / 120kmh
Cessna 206: 75kts / 86 mph / 139 kmh
Cessna Grand Caravan: 80kts / 92mph / 148kmh
Pilatus Porter: 70kts / 81mph / 130kmh
Twin Beach: 83kts / 95mph / 153kmh

Keep in mind that these are exit speeds under competitive conditions. Student conditions may differ. The Jump Pilot's Handbook (2005) says:

Quote

Terminal velocity of the human body is
approximately 110 knots (127mph) and at speeds below
70 knots (81mph) flying the human body in freefall is
more difficult.
Speeds of 60 knots (69 mph) will make it easier for
an inexperienced jumper to climb out onto the
step and reduce the chance of an unplanned
canopy deployment or the jumper falling off.
Exit speeds can be the subject of considerable
debate and you will be best guided by the
DZSO as to what is required for the particular
operation.
