Maybe I can shed a little light on this topic...
While this is a couple months old thread I figured I would add my 2 cents to this forum to possibly help add some perspective to this discussion from the meat missile's side of the coin...
Let me first start out by stating a few obvious points...
- No not all dropzones work the same way. Yes there are some idiot (#$@%) jump pilots but most of them are actually really good and helpful.
- The larger turbine based DZs will but dropping skydivers on a more regular basis during the day than the smaller Cessna DZs.
- Typical Cessna DZs only go to 10,500 AGL (climb time could be 25-35 min), turbine DZs will usually go from 12K-14K AGL (climb time can be as short at 8min to about 20 min depending on the aircraft)
- Technically jumpers are VFR.
Ok so a little background on me so you don't think I have just done a couple tandems and think I know what I'm talking about. I am an Accelerated Free Fall instructor (the way we teach people to skydive) and I am a tandem instructor. I have 698 skydives. I am also a private pilot with 160 hrs of flight time. If you are wondering I work at Skydive Atlanta based at OPN in Thomaston GA. (btw if you look at a current VFR sectional there is not a parachute symbol, and yes we have been working with the FAA for a long time to get one on the chart).
Skydiving operations first: I am going to speak in terms of our DZ although most of this can be inferred taking into account some of the things I stated earlier. Jump operations are announced ahead of time with usually a 2 min call "skydiving over Thomaston in 2 min" and a "jumpers in the air over Thomaston 14K' and below" when we exit. We teach and are taught to spot the airport (landing zone), clear of clouds, and traffic. We can not see all aircraft but experienced skydivers know roughly where an aircraft should be if they are in the pattern or entering into it. We routinely call out any traffic we might see (even if it is not a conflict) to all jumpers in the airplane and our pilot will call out to us a rough position of any aircraft that might have been making radio calls in the area. during the freefall I would like to say we are still looking for traffic but honestly we're not typically. most formations will break between 4K'-6K' to gain separation to open out parachutes. That is the time we start looking again for traffic (other skydivers and aircraft). Just as a reference typical free fall has us passing 1000' of altitude every 5.5 seconds. from break to opening usually will be maybe 8 seconds max. FAA requires us to be open by 2000' AGL but most will be open from 2500-5000'.
Ok WHERE are we falling?.... our spots are all dependent on the winds up to 15K' if you know the winds you can quickly guess where we are. We will always be upwind. There is some drift in freefall but majority of our spot will be for the winds at 5K' and below since our drift under canopy is much greater.
Skydivers are taught to get over their landing area and fly a pattern just like pilots do. our pattern entry altitude is typically 1000' AGL and it is very close in to our landing area, WAY INSIDE the pattern you would be flying at the same altitudes. We also have established procedures for an altitude NOT to cross a runway below (500' or 1000' is typical). Skydivers are taught to stay away from the runway at these altitudes assuming aircraft operations WILL be continuing.
Flying operations: ok my advice if I were flying around a dropzone. Skydiving operations are generally set up to allow flight ops to continue even while skydiving is going on if we work together.
- most importantly..... Never ever overfly mid-field while skydiving is going on (yes I have seen it during freefall). I don't really care if it is a "normal procedure" that you like to do, you will be playing Russian roulette.
- pay attention to the local frequency, the jump aircraft is required to announce jumpers in the air. As stated earlier 90% of jump operations will also be talking to the ATC facility covering the area so they might not be on the frequency the entire time.
- announce your position and intentions (like we're supposed to do anyway)
- fly an established pattern, if you are nervous then widen your pattern a little bit. I would suggest to stay outside the airport area until you are in a position to properly enter a downwind leg (preferably on a 45 degree entry)
- If the jump pilot is on the frequency and not slammed at the moment they typically would be willing to give you a quick reference of how far they have off set their jump run from the runway "jump run offset .5mi to the north"
As stated before, you are welcome to stay outside the area until canopies are on the ground, but at a real busy DZ you are going to get frustrated. Our field happens to also have some of the cheapest 100LL in the area so we have a steady stream of pilots landing to gas up. Most have gotten to know us and have no issues operating together. BTW I don't think I have ever heard a radio call for all the canopies are on the ground... most turbine aircraft are back on the ground and shutdown before the last tandems land.
We're all aviators, and skydivers love to talk as much if not more than pilots.... if you land at an airport that has a skydiving operation, by all means come over and say hi. If you have questions about how your local DZ handle their air operations ask them, most likely you'll end up with a nice conversation with the pilot and/or owner and have a much better understanding how they expect the skydivers to operate.
This post is getting long so I'll stop here. I will happily answer any questions I can. I hope this has helped someone.
