HOW MUCH FUEL SHOULD AN AIRCRAFT CARRY FOR THE TRIP? Explained

HOW MUCH FUEL SHOULD AN AIRCRAFT CARRY FOR THE TRIP? Explained

Have You Ever ‘Wondered?’ HOW MUCH FUEL DO AIRCRAFT NEED TO Carry? HOW DO YOU KNOW WHEN YOU’VE HAD ENOUGH FUEL? well here is the answer for that.

Regulators such as EASA and the FAA specify the minimum amount of fuel that a passenger jet must carry. Airlines.
are required to carry significantly more fuel for a flight than is required to get from point A to point B in
case of an unexpected event such as an airport closure or aircraft emergency. Commercial flights typically carry
at least one hour’s worth of extra fuel on top of what is required to get to their destination, but this is
frequently increased by the pilots depending on the day’s circumstances.

Airlines must adhere to regulatory requirements when transporting fuel. The majority of government policies are
broadly similar and are detailed in each airline’s operating manual. According to EASA regulations (which are
very similar to those of the FAA and other authorities), the Captain must ensure that he has the following
minimum fuel before departure:

[the_ad_placement id=”article-ad”]

1. Travel Fuel
2. If a flight is planned with no alternate, divert fuel or hold fuel for 15 minutes.
3. Fuel Reserve
4. Emergency Fuel
5. Taxi fuel
6. Additional Fuel

Lets discuss each fuel and its usage.

1. Trip fuel
Fuel required from takeoff to touchdown, assuming departure on the SID from the assumed runway and arrival using
the STAR for the assumed arrival runway and routing based on the forecast wind.<break time=’2s’/>

2. Diversion Fuel

Fuel consumed during the go-around at the destination, as well as the climb, cruise, descent, approach, and
landing at the alternate airport of choice. Normally, this is calculated as the planned landing weight minus the
contingency fuel.

If no alternate flight is planned, the diversion fuel figure must be replaced by 15 minutes of holding fuel at
1500 feet above the destination airfield in standard conditions.

3.  Reserve Fuel
Is there a minimum amount of fuel that must be present in tanks at the alternate airfield? (or destination if no
planned alternate). The figure is based on 30 minutes of fuel holding at 1500 feet in a clean configuration with
a planned landing weight.

4. Contingency Fuel
This is done to account for unanticipated deviations from the planned operation. For example, different winds or
temperatures than predicted, or ATC restrictions on levels and speed. It can be used at any time after delivery
(once aircraft moves under its own power). It cannot be planned to be used previously. It is more likely to be
used for flight or arrival delays.

5. Taxi Fuel
This is fuel for the APU to burn on the ground, start the engine, and taxi out. Most airlines calculate this
using statistical data and the taxi time in minutes.

6. Additional Fuel
If the existing total fuel is insufficient to cover an engine failure or de-pressurization at the most critical
point along the route, additional fuel is planned and loaded. Fuel planning must allow for a descent and trip
fuel to an alternate airfield, a 15-minute hold at 1500 feet, and an approach and landing.

Pakistan’s Ambitious Plan to Acquire and Produce Chinese FC-31 Stealth Fighter

Pakistan’s Ambitious Plan to Acquire and Produce Chinese FC-31 Stealth Fighter

Pakistan is embarking on an ambitious endeavor to bolster its air defense capabilities with the acquisition and potential local production of the Chinese FC-31 stealth fighter jet.

Talks are reportedly underway between the Pakistan Air Force (PAF) and the Shenyang Aircraft Corporation, the developer of the FC-31, signaling a significant leap forward for Pakistan’s military aviation prowess.

The FC-31, a mid-sized, twin-engine fifth-generation fighter, promises advanced air combat capabilities, including stealth technology that surpasses anything currently in the PAF‘s fleet. With plans to retire the JF-17 production line by 2030, the FC-31 could emerge as the new flagship aircraft, offering unmatched performance and versatility.

Experts speculate that Pakistan’s interest in the FC-31 could also signal broader implications for the international market. As China develops both land and carrier versions of the FC-31, analysts foresee it becoming a cost-effective alternative to pricier options like the F-35, potentially challenging the dominance of the US aerospace industry and reshaping global strategic rivalries.

Adding complexity to the deal is China’s push for the WS-13 engine, previously rejected for the JF-17 but now under consideration for both the FC-31 and future JF-17 variants. Engine standardization could streamline logistical and maintenance processes for the PAF, further enhancing the appeal of the FC-31.

While negotiations continue, the success of the FC-31 acquisition and local production hinges on several factors, including the outcome of the WS-13 engine discussions. Pakistan’s pursuit of the FC-31 comes amidst its eagerness to replace its aging fleet, with previous attempts to upgrade its F-16s by the United States due to geopolitical pressures.

Amidst these developments, Pakistan previous interest in the Turkish-made Kaan fifth-generation fighter underscores its eagerness to replace its aging fleet. Despite previous attempts to secure upgrades for its F-16s from the United States, Pakistan’s quest for advanced aerial capabilities has led it to explore alternative avenues, with the FC-31 emerging as a promising contender in its pursuit of air superiority.
