August 21, 201015 yr In the manual of the LCF, it states that there is no APU installed on the LCF. Since a normal engine start involves APU usage, how is the engine start procedure correctly performed in the LCF?

In the real world I believe a ground bleed air supply is used. Mark Adeane - NZWN

August 22, 201015 yr Commercial Member Without the APU, the aircraft would require an external bleed source to start the engines. GPU alone will not cut it. It'll give you all the electrical power you need, but you will not be able to spin the engines to light them.Kyle Kyle Rodgers

August 27, 201015 yr Just turn your nose in to some 50 knots winds. Should do the trick... Hauke Verrept
September 2, 201015 yr Just turn your nose in to some 50 knots winds. Should do the trick...Better get out and push!I belive there are usually two types of ground air available. One is a lower pressure variety that can be used for cabin cooling. The other is a Ground starter unit, which is of a higher pressure, enough to start the engines. I am not sure how much pressure you can get from the ground unit, may try and start only one engine at a time for the first two, then you should have plenty of bleed air to start the remaing two together.

November 14, 201015 yr There are 2 "types" of ground air units for aircraft. Neither have anything to do with the other, as the systems are separate. The 1st is an environmental conditioning unit. Also known by the rest of the world as an A/C. Next time you’re at an airport, take a look at the large diameter, usually yellow, hose going from the gate or ramp to the belly of the aircraft. This is connected to an a/c cart or jet way ECS unit to the airplane. Most of the systems are just a/c however there are some that provide cabin heating as well. The concept is identical to what many have in their homes.The 2nd unit is called an air start. All it is is a jet engine in a box. Its only purpose is to provide pressurized air to the aircraft for engine start. Now a days, you very rarely see this things making noise at an airport. Older aircraft that don’t have an apu require these units. And there are very loud and dangerous to the line guy who’s running it. There is a small diameter hose that connects the aircraft. The couplings / hoses have a tendency to "fly off" the unit once you hit the build psi switch on the unit. In our old terminals here at KJAX, there were 2 very large dents in the side of the building from air start couplings flying off the hoses and hitting the side of the concourses... Gotta love those 727's!ThanksJR JR
