Question about Embraer E-Series and and Bombardier CRJ's

[Panama Jack]

Could anybody please tell me whats the maximum operating temperature of the Bombardier CRJ 200 & 900 and the Embrarer E-series jets during takeoff/landing?

Engine limitations on the E190:

PARAMETER MIN MAX
N1 - 100%
N2 59.3 100%
ITT: - -
Ground Start 740°C
Inflight Start - 875°C
Normal and Maximum Take-off and
Go Around - 983°C(1)(2)(3)
Maximum Continuous - 960°C
OIL PRESSURE 25 psi (4) -
OIL TEMPERATURE: - -
Continuous - 155°C
Engine Starting -40°C Not good if you are operating into/out of YEG in the winter

APU Limitations:

OPERATIONAL LIMITS
PARAMETER MIN MAX
START: TEMPERATURE -54°C - ISA + 35°C This will probably affect you more than the engine start limit.
ALTITUDE - 30,000 ft
OPERATION: - TEMPERATURE -62°C ISA + 35°C
ALTITUDE: ELECTRICAL GEN - 33,000 ft
BLEED - 15,000 ft
TO ASSIST ENGINE START - 21,000 ft
ROTOR SPEED - 108%
EGT: - START - 1032°C
CONTINUOUS - 717°C

Minimum Jet A...............................................................................................................................-37oC
Minimum Jet A-1, JP 8, QAV 1......................................................................................................-44oC
FUEL TANK TEMPERATURE

OK yycflyguy,

So after sifting through all of that, the executive summary would read: "maximum temperature, at sea level, for takeoffs and landings is 50 degrees centigrade"?

[yycflyguy]

Yeah, that is to start the APU so not necessarily a landing limitation. The other end of the spectrum is -40 for engine start... but I think hell would have to freeze over for that to be a concern where you would be operating.

[Rockie]

Is this what you're looking for on the Embraer? 52 degrees C for takeoff.

[yycflyguy]

52 degrees C if you are operating 1000 feet below sea level! Like I said and the graph shows ISA +35 degrees C.

[Rockie]

Well, he didn't say where he was operating. It could have been an airfield serving the dead sea for all I know. But...you win.

[Go Guns]

CRJ200 and 900
Minimum ambient temperature approved for takeoff ‐40°C

CRJ200
Maximum ambient air temperature for takeoff and landing 50°C

CRJ900
Maximum ambient air temperature for takeoff and landing ISA+35°C

Well, he didn't say where he was operating. It could have been an airfield serving the dead sea for all I know. But...you win.

Yea! I finally win something in life... and to celebrate it shall be my new signiture.
