125 in Lagos?
 
Maybe I'll check my logbooks when the current Mrs BM gives me a break...

Anyway whilst fying for a local tribal chief (awash with new oil $$$) out of Lagos in the 80s ..a couple of local lads (one only just qualified at OATS I think) .. attempted a single-engine take-off in a 125 (400 seies I recall). I can still recall the inevitable -especially @ ISA + 25 degrees C... pitch-up at end of (long) runway, stall, spin, crash, burn. Tragic. Stupid. bm:ugh:

Please remember guys..the sim is essentially designed to HANDLE like the aircraft.... not necessarily PERFORM like it! Cheers bm

NTSB Identification: SEA98FA047 .
The docket is stored in the Docket Management System (DMS). Please contact Records Management Division
Accident occurred Thursday, March 19, 1998 in PORTLAND, OR
Probable Cause Approval Date: 2/15/2001
Aircraft: Aerospatiale SN-601, registration: N600RA
Injuries: 4 Uninjured.
The cockpit voice recorder (CVR) recording indicated that the pilot was unable to start the right engine before takeoff, and elected to attempt takeoff with the right engine inoperative. Witnesses reported that the airplane's nose lifted off about 4,100 feet down the runway and that it then became airborne with its wings rocking, attaining a maximum altitude of 5 to 10 feet above the ground before settling back to the ground, departing the right side of the runway and entering an upright slide for about 1/2 mile. Investigators removed the right engine starter-generator from the engine after the accident and found the starter-generator drive shaft to be fractured. The aircraft has a minimum crew requirement of two, consisting of pilot and copilot; the copilot's seat occupant, a private pilot-rated passenger, did not hold a multiengine rating and thus was not qualified to act as second-in-command of the aircraft.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:

The pilot-in-command's decision to attempt takeoff with the right engine inoperative, resulting in his failure to maintain directional control or attain adequate airspeed during the takeoff attempt. Factors included a fractured right engine starter-generator drive shaft, resulting in an inability to perform a normal engine start on the ground.

Thank you all for your input
 
Apart from one or two "comments" all responses were educational.

In summary if I was stuck, with a hord of (non PC):=, Zulu spear chucking SLF, in hot persuit out of the terminal building, with the 101 cl bottles of red bull, I would make my exit with even the G550 APU only running.
After all the APU thrust vector is consided as a positive number.
Not forgetting the TROV.....

You would be surprised......
 
A Falcon 2000EASy with only a few thousand pounds of fuel, temperature of around 20C will do it and require just about all of 7000Ft. Dont ask me how i know, nuff said.
