Can we say that 2 aircrafts that are 100 nm apart for both of their departures, heading to the same destination, the ODP and MSA is taken into fact, but the the aircraft closest to the destination after departure would be assigned a lower altitude, right? And the the other aircraft further away or right behind him, would get the higher altitude. Here from Timmins airport, there have been instances where 3 aircrafts departed within say 5 or 10 minutest of each other and assigned departure radials. Example, departures southbound to Toronto Pearson Airport, departs rwy 21 direct to Mans VOR, he would intercept the 209 degree radial, and a Bearskin flight, same rwy21 departure to Sudbury CYSB would be asked to interecept the 179 degrees radial (V5 airway) and the 3rd aircraft would be asked to climb VFR if able, until the first 2 guys are radar identified at 10 000 feet for separation rules. If aircraft # 3 could not climb VFR, he would be asked to climb VFR, and not above 4000, or his departure woud actually be delayed altogether. Let me know how this sounds.
