Typically, the normal takeoff procedure will result in you climbing well above any climb gradient requirement on a SID or ODP. If there is no SID or ODP, then a 200 ft/NM climb gradient is required. For takeoff the minimum takeoff speed, all engines operating is V2+10. That provides you sufficient stall margin with 30 degree bank.
I can get into a whole bunch calculations, etc. concern how to compute a percent climb gradient and rate of climb when you have a SID or ODP climb gradient in feet/NM. The Collins Proline 21 has a neat feature that makes this easy. Use the Flight Path Vector.
If you have a SID with a 400 ft/NM climb gradient, after takeoff make sure that the Flight Path Vector remains 4.0 degrees or more above the horizon. The climb gradient in feet/NM roughly equals the flight path angle in degrees - See the US Government Terminal Procedures Publication Legend below.
Turbojets are generally capable of meeting a 500 ft/NM climb gradient on a SID or ODP without much further consideration up to 1500' above the airport elevation simply on the basis of the aircraft's OEI takeoff climb requirements. Again, it is not required nor expected that you meet the SID or ODP climb gradient with OEI.
Initially, rotate to the TO command bar pitch attitude. That's to prevent on over-rotation accident. After the aircraft is accelerating, then use FLC and 200 Kts to continue the climb. See FCOM 1 takeoff procedure below.
