One hundred and forty slots are available for the five flying courses held each year at Florennes. The majority of these slots (118) are assigned to the seven MoU-signatory nations. In 1999 the slot allocation was as follows: Belgium 12 slots, Denmark 4 slots, Germany 28 slots, Italy 16 slots, the Netherlands 14 slots, the UK 28 slots and the USA 16 slots. The rest of the slots are sold to guest nations : Canada, France (which receives a number of free slots in return for the use of its low-flying areas for TLP courses), Greece, Norway, Portugal, Spain and Turkey. The number of slots bought by each nations varies each year according to their requirements and operational commitments.

The following aircraft types are regular attendants : Belgian Air Force (F-16), Royal Danish Air Force (F-16), France's Armée de l'Air (Jaguar, Mirage F.1CT/CR and Mirage 2000C/D/N), German Luftwaffe (F-4 Phantom and Tornado), German Marineflieger (Tornado), Hellenic Air Force (F-16 and Mirage 2000), Italian Air Force (AMX, F-104, Tornado IDS and F.3), Italian Navy (AV-8), Royal Netherlands Air Force (F-16), Royal Norwegian Air Force (F-5 and F-16), Portuguese Air Force (F-16), Spain's Ejercito del Aire (EF-18 and Mirage F.1), Spain's Armada (EAV-8), Turkish Air Force (F-4 Phantom and F-16), UK's Royal Air Force (Jaguar, Tornado GR.1/4 and F.3) and the US Air Forces in Europe (F-15C/E and F-16C).

For each course, one participant is responsible for bringing a two-seat aircraft so that a TLP instructor can take part in the missions and monitor them from the air. For the last two weeks of every flying session, external participants are added. Most of the time they are made up of 4 to 6 additional air defence aircraft in the form of F-4 Phantoms, F/A-18s, F-104s, Mirage 2000Cs, F-16s or Tornado F.3s.

ECM-tasked aircraft are also regularly added to the flying programme of week 3 and 4. Spanish Falcon 20s, Italian PD.808s and Canadian CE-144s have been seen to operate in this role. Additionally, the TLP instructors may come up with an original scenario for some missions which can include C-SAR assets like helicopters or A-10s (click here to see the external C-SAR participants for TLP 2000-4). Transport aircraft (C-130s and Transalls) can also be seen flying one or two missions with the other participants but that is exceptional. Finally, the TLP missions are often controlled by an E-3 AWACS which normally operate from its home base.
