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.
