In the US, most ARFFs are maned by a crew of 6 men, only switching to 2 once the unit arrives on scene. The remaining 2 men stay in the ARFF to man the cannons.
Also, the 2 new calls both require only one ARFF. This response may be good for a Cessna having a small fire, but if a 747 had a cabin fire, they might deploy 3-5 ARFFs before the airplane touches down.
I like the airport update, and just want to see some improvements.
I saw it in another post, but I would also like to see a stair vehicle for large airports.
