.
Monitor parameters with regard to time limits.
.
At N2 = 50 % (43% for V2500), check start valve cross line.
.
MAN START pb to "off".
.
Engine mode selector to NORM.
.
Determines and applies appropriate engine start procedure (Auto or manual).
.
Monitors engine parameters on ECAM during the starting sequence.
The action of putting the engine mode selector switch to NORM will trigger the after start scan (FCOM 3.03.09 [SOPs - After Start]). This is followed by the after start checklist.

05 - TRAINEES’ ACTIONS
On receipt of taxi clearance, set nose light "on". While maintaining pressure on pedals, release the parking brake. Check brake pressure reads zero, indicating a successful hydraulic power changeover. At light weights no power is needed for the airplane to start moving. At heavy weights apply minimum power smoothly to get the aircraft moving, thereafter little power is required to maintain motion.

REV 21 MAY 98
Avoid high power settings due to the risk of FOD (Foreign Object Damage). Maintain suitable ground speed with reference to the ND. Do not ride the brakes. Allow aircraft to accelerate, brake, then accelerate again. This reduces brake wear. On carbon brakes, brake wear is a function of number of brake applications not the pressure applied nor the duration of the braking. Brake wear is greatest when the brakes are cold. Carbon brakes do not "fade" at high brake temperatures.
If brakes fail during taxi, select A/SKID & N/W STRG sw to "off ". Pedals should be released when switching A/SKID to "off ". Steering is then achieved through differential braking. Only in extreme emergency should the aircraft be stopped with parking brake, as full pressure is immediately applied.
