What are standard takeoff minimums?
Standard takeoff minima are one statute mile for aircraft having two engines or less and one-half statute mile for aircraft having more than two engines. Specified ceiling and visibility minima will allow visual avoidance of obstacles during the initial climb at the standard climb gradient.
How do I calculate takeoff minimums?
The easiest way to find if an airport has takeoff minimums is to look at an approach chart. On the FAA charts, you will see a black triangle with “T” in it which is often called the “troubled T.” It’s troubling because there is something, most likely terrain, keeping pilots from executing a leisurely climb.
Where can I find alternate takeoff minimums?
If you see a “T” within a black, upside down triangle on an FAA approach plate, the airport has non-standard takeoff minimums. You can also find a list of these airports at the beginning of the FAA’s chart packet.
What is a zero zero takeoff?
A “zero-zero” takeoff is generally considered to occur when the pilot is taking off into low IFR conditions in which runway visibility is limited to the length of the runway or less and very low ceilings. Things like fog, snow squalls, heavy precipitation, or other similar conditions many times cause this to happen.
What does squawk 7500 mean?
being hijacked
If an aircraft transmits or “squawks” 7500, it is understood that the crew is letting everyone know they are being hijacked. The JetBlue pilots were trying to squawk 7600, which is the code for radio failure. They missed by one digit.
What is the 123 rule?
The 1-2-3 Rule is means of avoiding winds associated with a tropical cyclone by taking into account the forecast track error of the National Weather Service over a 10 year period which is approximately 100 nm in 24 hours, 200 nm for 48 hours and 300 nm in 72 hours.
Can you take off in zero visibility?
Under Part 91 operations an aircraft can takeoff with zero visibility (however dangerous that might be). Show activity on this post. It all depends upon the equipment the aircraft has board, the infrastructure at the airport that is landing on, and the regulations under which the flight is being conducted under.
How do you calculate alternate minimum?

When can you use lower than takeoff minimums?
The OpSpecs permitting takeoff with lower than the standard minimums allow for departure with visibility lower than 1 mile—as low as 500 feet of runway visual range (RVR).
What does squawk 7777 mean?
Under normal circumstance even interception missions are supposed to work with ATC. Squawking 7777 is sort of a last resort thing for the DoD to tell ATC to get out of their way and get everything else out of their way.
Why do pilots say pan?
The term pan pan, besides being known as airplane talk, is used in radiotelephone communications to signify that there is an urgency on board a boat, ship, aircraft, or other vehicle. It is referred to when it is a state of urgency, but not when there is an immediate danger to a person’s life or to the vessel itself.
What are basic VFR weather minimums?
Basic VFR Weather Minimums
cloud ceiling at least 1,000 feet AGL; and. ground visibility at least 3 statute miles (usually measured by ATC but, if not available, flight visibility at least 3 statute miles as estimated by the pilot).
Is RNAV a precision approach?
While these next two levels of RNAV minimums are not technically precision approaches (they do not meet international standards to be called such), they can be considered “precision-like.” The familiar localizer performance with vertical guidance (LPV) approaches are in almost no material way different from an ILS.
What is minimum RVR for takeoff?
Although RVR 500 is the lowest authorized RVR when the takeoff is based upon outside visual references, RVR 300 is the lowest authorized RVR when using a takeoff guidance system.
What is a low visibility takeoff?
Low visibility take-off (LVTO) means a take-off with a Runway Visual Range (RVR) lower than 400 m but not less than 75 m. ( IR-OPS Annex I) Note that ICAO requires LVP for all departures below 550m RVR, not just LVTO.
What is the 123 rule in aviation?
You need to name an alternate airport on your IFR flight plan if, for the period of time one hour before and one hour after your estimated time of arrival, the weather is forecast to include a ceiling of 2,000 feet agl and/or visibilities less than three statute miles (the 1-2-3 rule).
What is a takeoff alternate?
A Take-off alternate is an aerodrome at which an aircraft would be able to land should this become necessary shortly after take-off and it is not possible to use the aerodrome of departure.
Can airlines take off in zero visibility?
Yes, most commercial aircraft are capable of landing in thick fog, but it can depend on the type of aircraft and the facilities associated with the runway and airport. Some planes can land when the visibility is as low as 75 metres.
Why do pilots say v1 rotate?
Pilots say rotate because it is a verbal queue that an airplane has reached its predetermined rotation speed (frequently abbreviated to Vr). This is the speed at which control inputs can be applied to lift the nose off the runway and make the airplane fly away.
Why do pilots say crosscheck?
It’s an instruction to set the doors to automatic mode so that emergency evacuation slides will deploy when the door is opened. The cross-check means that after arming their assigned door, the flight attendant should check that their opposite number has also armed their door.
Why is Mayday three times?
A typical distress call will start with the word “Mayday” being said three times in a row so that it is not mistaken for another similar-sounding word or phrase.
Why is pilot called Mayday?
The Mayday call originated in the 1920s when a senior radio officer, Frederick Stanley Mockford became the first to use this signal to indicate an emergency at London’s Croydon Airport in London.
Can VFR pilots fly in rain?
To fly VFR, a pilot needs to see the horizon and use other visual cues to reliably maintain straight-level flight. Because rain affects visibility it can make VFR pilots uncomfortable even when the conditions are still VFR-legal.
Can student pilots fly above clouds?
The only regulatory restriction is that student pilots are not allowed to fly above a cloud layer without ground reference. VFR over-the-top can be a very useful tool to get above a cloud layer instead of flying in haze or restricted visibility below the clouds.
Is RNAV better than ILS?
RNAV approaches are safer and also simpler to use and manage than standard navaids such as VOR’s and ILS’s, which must be checked for flight under such tolerances. Standard VOR and NDB approaches are removed at most airports in the US and substituted by RNAV approaches.
