Whew a lot of information has been posted and some of it not 100% accurate.
I'll give you my real-world experience in coordinating with a local MediVac program (2 heli).
- A) As noted the hospital "usually" has no real contact other than the "Incoming" notification to the ER so they can start getting ready.
- B) Most are operated by a 3rd party and they usually have a base/office somewhere far away from your actual hospital. It's usually at another much larger hospital in a larger city that you wouldn't want to fly near anyway.
- C) Finding the contact information for this 3rd party can be an exercise in "chasing your tail". Don't give up and get discouraged.
- D) It took us weeks to track down the right person(s) to talk with about local MediVac operations. Once we had the right people we made an appointment and had a face to face. We explained our operations (Commercial 333/107) and often times operating within sight of the hospital. The problem is they don't have a lot of time to chit-chat when things get busy so we worked out a system that wasn't cumbersome to us but also wasn't a time waste for them.
- E) There are no "Designated" approach paths for a MediVac usually unless terrain/structures etc are a factor. They could be arriving from any direction and just about any altitude depending on how far out the pickup was. Don't rely on knowing where they come from because it changes.
We established a routine to place a phone call their "Flight Watch" when we are operating within a certain distance from the helipad. Outside of that distance we just stay extra vigilant and are always ready to ditch the drone if needed.
Process:
We call Flight Watch 30 minutes before the flights commence. We have our exact location (in proximity to the heli pad), our intended flight altitude MAX, estimated flight duration, and # of aircraft being operated. We give that information, my name and a call back number to them. We also tell them we will call at the end of the flight sessions when we are clear of the area. We make a note on our logs of this conversation, time and their name. We also make sure we call back to let them know we are clear of the area and no longer a concern.
We've been doing this since (IIRC) 2014 or so and it's worked splendidly. They have contacted us half a dozen times to let us know that
MAMA (1 or 2) is inbound to our location and 1 time to let us know
MAMA (1 or 2) was going to be landing near our location due to an accident. Every time they gave us ETA and we ceased operations until "she" had landed or cleared the area.
Keep in mind this isn't daily "hobby" flights but Commercial Ops in the area that are in close proximity to the heli pad. For daily hobby flights they may ask for something different or just say "Keep and eye out for us". You won't know until you contact them.
Good luck and KUDOS for trying to go the extra mile for safety. The whole industry should be thrilled to have Safety Conscious operators in the group.
