Note: Use the CX# Wind Correction menu. Do not use the wind Component menu.

Calculation:
3 Engine TAS 320
68 knots tailwind
GS out: 320 + 68 = 388 knots
GS Home: 320 - 68 = 252 Knots

For the distance to CP use the engine inop speed or reduces TAS
Distance to CP = (Total Distance x GS Home)/(GS out + GS Home)
Distance to CP = (2180 x 252 )/(388.41 + 252
Distance to CP = 549360/640.41 = 857

For the Time to CP use the all-engine speed as you are not going to keep flying out after a failure
Calculation: GS out 549.89 knots

Time to CP = Distance to CP/GS out x 60
Time to CP = 857/549.89 x 60 = 93.51 mins or 1.558 hours or 1 hour 34 mins

A person operating an aircraft in VFR flight in Class C airspace shall ensure that:
(a) the aircraft is equipped with:
(i) radio communication equipment capable of two-way communication with the appropriate ATC unit, and
(ii) a transponder and automatic pressure-altitude reporting equipment, and
(b) a continuous listening watch is maintained by a flight crew member on a radio frequency assigned by ATC.

Airspace classified as Class C becomes Class E airspace when the appropriate ATC unit is not in operation.

Use the CX3 Airspeed function. Enter the OAT -30C; CAS 199 knots; Pressure alt 24000 ft. The answer is 288.75 knots.

Note: ignore the position and instrument error, density and pressure error, and temperature rise

All pilots will be advised that simultaneous LAHSO are in progress.
Controllers will issue appropriate traffic information.
ATC must include specific directions to hold short of an intersecting runway (e.g. “Cleared to land Runway 27, hold short of Runway 36.”). Pilots, in accepting the clearance, must read back “Cleared to land Runway 27, hold short of Runway 36.” Having accepted the hold-short clearance, pilots are obligated to remain 200 ft short of the closest edge of the runway being intersected.
If, for any reason, a pilot is unsure of being able to comply with a hold-short clearance, the pilot must advise ATC immediately that they cannot accept the clearance; it is far better to be safe than sorry.
If a rejected landing becomes necessary after accepting a LAHSO clearance, the pilot must maintain safe separation from other aircraft and vehicles and notify ATC as soon as possible.
