Starting in a tailwind is usually successful using normal starting procedures. An exceptionally strong tailwind (in excess of approximately 20 knots) may prevent positive N1 rotation at a max motoring RPM of 15% to 20% N2. In this condition the Captain should do one of the following:
.  
Have the aircraft towed into a position (headwind or crosswind) in which the N1 rotation stops or is in the correct direction.

OR

.  
Have the ground crew verify that both engines are clear of personnel and equipment, then deploy both engine reversers.  After approximately two minutes, have the ground crew verify zero N1 rotation.  Prior to starting an engine, verify the reverser is stowed and latched.

Engine Warm-up
Engines shutdown for two hours or less do not require warm-up time prior to takeoff.  Engines shutdown for more than two hours should be warmed up (normal taxi operation) for up to 5 minutes prior to takeoff.  This will minimize any adverse thermal stresses on the engines.  When taxi time is less than 5 minutes, it is not necessary to delay takeoff for warm-up as long as the engines are started at the gate.
Engine Compressor Stall
The compressor stall of an engine is not normal at any time in either forward or reverse thrust.  Compressor stalls indicate a malfunction of the engine, such as blade damage or a fuel control unit error, and should be written up in the aircraft logbook.
AFTER START CHECKLIST
The Captain will call for the AFTER START CHECKLIST after the engine(s) have reached a stabilized idle and the headset operator has been cleared to disconnect.  The AFTER START CHECKLIST will be completed prior to releasing the brakes for taxi.

F/O CHALLENGE CAPT RESPOND Electrical System................................ .......................................CHECKED
Check both AC generators for allowable voltage and frequency.  Return the VOLT/FREQ selector to the BATT AMP position.  Scan the AC load meters for proper indications.  Verify that all DC load meters indicate some load.
 Verify that both CSD OIL annunciator lights are out and that both CSD oil temperatures are below the yellow band. If right Engine Restart: only check of right generator/CSD is necessary.
Note:  The AC crosstie check is required on the First Flight of the Day only.  All electrical buses must be powered by the engine driven generators.  If external or APU electrical power is connected, the EXT PWR and APU L and R BUS power switches must be off.  The AC X-TIE switch must be in AUTO.
AC Crosstie Check:
L Gen Switch.................................................................................OFF

Move L GEN switch to OFF. Observe left AC load meter indicates zero and right AC load meter indicates approximately double. Observe L GEN OFF light is on, and all BUS OFF lights remain out.
L Gen Switch................................................................................ ON

Move L GEN switch to ON, observe left AC load meter indication increases, and right AC load meter indication decreases, both showing some load.  All electrical system warning and caution annunciators should be off.
R Gen Switch...............................................................................OFF

Move R GEN switch to OFF. Observe right AC load meter indicates zero and left AC load meter indicates approximately double.  Observe R GEN OFF light is on, and all BUS OFF lights remain out.
R Gen Switch................................................................................ ON

Move R GEN switch to ON. Observe right AC load meter indication increases and left AC load meter indication decreases, both showing some load.  All electrical system warning and caution annunciators should be off.
Galley Power, Ignition....................... .........................................ON, OFF

Note:  Anti-ice should be used during ground operation if outside air temperature is less than 6°C (42°F) and visible moisture is present or dewpoint and outside air temperature are within 3°C (5°F) of each other.
