# Often asked: What Does 1000 Ft On Top Mean Aviation?

## How do you read flight level?

Flight levels are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, while being a multiple of 500 ft, therefore always ending in 0 or 5. Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as ” flight level 320″.

## What is the difference between VFR on top and VFR over the top?

It’s easy confuse ” VFR-on-top ” with ” VFR over-the-top.” A VFR on-top clearance is an IFR clearance that allows pilots to fly at VFR altitudes. VFR over-the-top, on the other hand, is an operation where you maintains VFR cloud clearance requirements while operating on top of an overcast layer.

## What is the max altitude for VFR flight?

First, you only need to comply with the VFR cruising altitudes if you are flying more than 3,000 feet above ground level (agl). Below 3,000 feet agl, you are not required to follow the altitude rule (although it’s a good idea) and neither are other aircraft.

## What is the highest flight level?

Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet. The highest business jet flying today reaches 51,000 feet.

## What is the lowest flight level?

The minimum safe altitude of a route is 19,000 feet MSL and the altimeter setting is reported between 29.92 and 29.43 “Hg, the lowest usable flight level will be 195, which is the flight level equivalent of 19,500 feet MSL (minimum altitude (TBL ENR 1.7-1) plus 500 feet).

## What is the proper phraseology to say the altitude 10000?

Confusing Phraseology ‘ Phraseology contributed to this incident.” “To correct future problems like this, the altitude should be given in the form of ‘ ten thousand ‘ or ‘eleven thousand’, instead of saying ‘one-zero’, or ‘one-one-thousand. ‘ There is too much of a chance of error.

## Can you fly over clouds in VFR?

“The short answer is yes. You may legally fly on top as long as you can maintain the appropriate VFR cloud clearances. VFR – on -top is conducted by an instrument-rated pilot on an IFR flight plan. It allows the pilot to change altitudes, provided VFR cloud clearances are maintained.

## How do you ask for the VFR on top?

You can request it on the ground, usually from clearance or ground control at a towered airport. Simply ask for an IFR climb to VFR-on-top. The controller will need to know your type aircraft and direction of flight. The clearance will usually have a clearance limit of a nearby VOR or other navaid.

## Do airlines ever fly VFR?

Generally the airlines operating procedures will only permit IFR operation. Occasionally non-revenue flights for aircraft positioning etc, will operate VFR for expediency. As far as I know, the size of the aircraft does not matter much. You just cannot plan airline flights (carrying passengers) in VFR.

## Can you fly VFR at night?

There’s no difference between flying in daylight and flying at night —except you can ‘t see anything. Even if you haven’t flown at night for year or more, you ‘re perfectly legal to blast off solo at midnight in a single-engine airplane under an overcast with three miles of drizzly visibility.

## What are basic VFR 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).

## What is BTH Flight Rule?

BTH probably means: Begin. Total-engine-overhaul-shop.

## How cold is it at 35000 feet?

How cold is it up there? The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.

## Can a plane fly at 60000 feet?

Some aircraft can fly higher Concorde has been the only significant exception amongst commercial aircraft. It could fly up to 60,000 feet due to the increased lift generated when flying at much higher speeds. At low altitudes, drag would prevent it from reaching its high speeds.

## Can you breathe at 35000 feet?

Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn’t have trouble breathing.
