GO/NO-GO DEPICTIONS

 
1.  "GO" (A TYPICAL SITUATION, with Vmcg low ):
 
Vmcg    ->       Vrot     ->       Vr
 

2.  "GO" ( SPLIT - MARKERS ):
 
Vmcg      ->       Vr      ->      Vrot
 

3. "GO" ( NOT TYPICAL, BUT POSSIBLE; COMPARE WITH #1 - AS LONG AS Vrot IS BEFORE Vr, IT DOESN'T MATTER WHERE Vmcg is.)
 
Vrot        ->       Vr      ->     Vmcg
 

4. "NO - GO":
 
Vr        ->       Vmcg     ->      Vrot
  xxxxxxxxxxxxxx                  For split-marker takeoff Vmcg must be lower than Go speed.

5. "NO- GO":
 
Vr       ->         Vrot      ->      Vmcg
  xxxxxxxxxxxxxxx                 For split-marker takeoff Vmcg must be lower than Go speed.

TECHNIQUE:
If Vgo = Vrot, then Vmcg is not a factor.
If Vgo not = Vrot, (split markers), then Vmcg MUST < Vgo
If Vgo = 147 KCAS or Vbmax, then Vcefs MUST < Vgo.
ANOTHER TECHNIQUE:
Vr is the lowest of these three (Vr, Vrot, Vmcg) you will have a "No-Go" situation.
