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.
