Questions tagged [aircraft-limitations]

All aircraft have specified performance limitations that they cannot (or at least should not) exceed, for altitude, speed, weight etc.

Every aircraft's operating handbook includes the operating limitations of the aircraft. These are limits for altitude, speed weight etc. that have been tested and documented by the manufacturer. Pilots should not operate an aircraft outside its limitations for safety reasons, and doing so may be illegal under local regulations.

Limitations can apply to many areas of operation, including:

  • Airspeed, e.g. maximum airspeed with flaps extended
  • Engine, e.g. maximum RPM or manifold pressure
  • Weight and balance, e.g. maximum takeoff or landing weight
  • Maneuvers, e.g. no spinning
  • Flight rules, e.g. no IFR flights

It's important to note that performance limitations are set by the manufacturer during the testing and certification of a new aircraft type and there may be other limits set by regulation that pilots must also observe.

Use this tag for all questions about limitations on aircraft performance. Questions about limitations set by law should usually be tagged with the appropriate regulations tag as well.

Is it possible to fly a B-24 under Bixby Bridge?

If that sounds like a ludicrous question it's because I believe it is, but here is why I'm asking. My grandfather flew B-24s in WWII and there was something of a local legend that he once flew a crew-laden Liberator under Bixby Bridge (near Big Sur…

What is the lifespan of commercial airframes (in general)?

You always hear that the Boeing 737 have been flying for so many years and the Airbus A310 for that many years, but of course that include new airframes being produced all the time. What is the lifespan of one airframe on average in general use by…

Is the aircraft used by NOAA specially modified?

I have just seen this short video showing "NOAA hurricane hunters" flying through current hurricane "Irma". My guess is that normally an aircraft would not be able/allowed to fly in winds sustained wind speed of 160kts, gusting to 180+kts, with the…

Why does maneuvering speed vary with weight?

Aircraft certified by the FAA under 14 CFR Part 23 have many V speeds, one of them which manufacturers are required to determine and publish in the POH is maneuvering speed, or Va. In aviation, the maneuvering speed (Va) of an aircraft is an…

Is there a tailwind limit while in cruise?

The storm Ciarán is, as of posting, making its way through the Atlantic Ocean with winds easily passing 300 km/h (161 kts). While this is going on, a BA flight took only 8 h 45 mins to do LAS-LHR with a tracked speed peaking at 1200 km/h (~mach…

Why don't airliners have any mirrors or cameras?

It seems odd that airliners do not have an easy way to monitor critical components on the exterior of the aircraft, should for example, a bird or something else strikes hard enough to cause damage. A mirror or camera would allow a pilot to see and…
