What is a critical point in aviation?
The Critical Point (CP) or Equal Time Point (ETP) is when an aircraft completes the same flight time of 2 potential diversions on the route. Calculating the appropriate CPs aids in decision-making when making a decision following a significant event such as an engine failure or an onboard medical emergency.
What is the point of no return in aviation?
Time in a flight when an aircraft is unable to return to the aerodrome from which it took off due to fuel problems. Beyond this point, the aircraft must fly to another destination.
How to calculate the same time?
To calculate the critical point (as the ETP is sometimes called) we use a simple formula:
- Distance to ETP = total distance x back GS / (front GS + back GS)
- Distance at ETP = 116 nautical miles x 95 knots/(65 knots + 95 knots)
- =68.9 nautical miles.
What is the point of safe return?
The Point of Safe Return (PSR) provides the pilot with the furthest point the aircraft can reach and safely return to the take-off point, with one stop, approach, one landing, and appropriate fuel replacement.
How do I find the point of no return?
Point of no return (AKA safe return point) These are calculated by dividing the predicted cruise fuel flow by the predicted ground speeds to the destination and flyaway, and the result is the fuel required per nautical mile traveled in each direction.
What do you call a point of no return?
The point of no return (PNR or PONR) is the point beyond which the current course must continue because a reversal is dangerous, physically impossible, or difficult or prohibitively expensive.
What do V1 VR and V2 mean?
When the aircraft reaches speed Vr, the pilot, not manipulating the controls, calls out turn, then the flying pilot applies the rear stick or side stick to raise the nose. … We can say that V1 is the engagement of airspeed. V2 is the speed at which the aircraft will climb in the event of an engine failure.
Is there a point of no return in relationships?
We know a couple who broke up last week. He said he was done. What most people don’t realize is that every relationship has a “tipping point,” a point of no return when daily dissatisfaction turns into “I’m done!”. …
What is the point of no return for a man?
At emission, the man reaches ejaculation death, the point of no return. The semen is deposited near the top of the urethra ready for ejaculation. Ejaculation occurs in a series of rapid contractions of the muscles in the penis and around the base of the anus. Involuntary pelvic thrusts can also occur.
